MOS (soil organic matter) is a natural carbon reservoir, and divided into different stages of decomposition according to its solubility and structural complexity. In view of this context, this work aimed to quantify the carbon content in the humic fractions of the soil organic matter under an agroforestry system in three toposequences in the swamp of altitude in Pernambuco, Brazil. The study was carried out on the Yaguara farm, and the studied areas were native forest and three toposequences of agroforestry system. Soil samples were collected in trenches 1.5 x 1.5 m, at depths 0-20, 20-40 and 40-60 cm, with four replications. The carbon concentrations in the humic fractions of the soil decreased with increasing depth. The area with agroforestry system had the highest concentrations of carbon in the humic fractions. The stocks of humic fractions found in the agroforestry system area showed higher average values in the top area 5.62, 9.72 and 22.53 Mg ha-1 in relation to native forest 4.84, 8.28 and 19.20 Mg ha-1, respectively for fulvic acid, humic acid and humine. Among the evaluated areas, the soil with agroforestry system top area has great potential to increase the carbon storage in the humic fractions of the soil.

Published: January 2024

The present study analyzed the effect of artificial perches in the supply of vegetal propagules and in the avifauna attraction in degraded area due to mining, in Rio Grande do Sul, Southern Brazil. The seed rain was sampled monthly from December, 2014 to April, 2015, in four collector tables arranged under artificial perches and in four control collector tables (without perches). We compared the seeds number by the Mann-Whitney U test (5% probability level) and used the Spearman correlation to calculate the association degree among the visitor birds on perches and the seeds number sampled in the collectors under perches. The avifauna monitoring was performed during the same period by fixed point method, totalizing 40 hours of sampled effort. The treatments differed statistically, with registration of 1588 seeds in the tables under perches and 237 seeds in the tables without perches. The sampling of seed rain in the perches followed the pattern of avifauna visitation, presenting high value to coefficient of association degree (0.975). We observed nine species of birds in the study area, and the Tyrannidae family was predominant. The species observed visiting the artificial perches were Knipolegus lophotes and Tyrannus melancholicus, both from Tyrannidae family. The number of sampled seeds demonstrates that artificial perches were efficient to return seed rain in the mined areas. The Tyrannidae family demonstrates to be the most effective group of birds to dispersion of seeds in the local of study.

Confidence intervals for the ratio of two means using the distribution of the quotient of two normals
Authors: Galeone Carlotta , Pollastri Angiola
Published: January 2024

In various scientific fields such as medicine, biology and bioassay, several ratio quantities assumed to be Normal, are of potential interest. The estimator of the ratio of two means is a ratio of two random variables normally or asymptotically normally distributed. The present paper shows the importance of considering the real distribution of the estimator of the ratio of two means, because generally the approximation to Normal is not satisfied. The estimated asymptotic cumulative and density function of the estimator of the ratio is presented, with several considerations on the skewness. Finally, a new method for building confidence intervals for the ratio of two means was proposed. In contrast to other parametric methods, this new method is worthy to be preferred because it considers the skewness in the distribution of the ratio estimator, and the confidence intervals are always bounded.

El estudio se centró en la formulación de estrategias gubernamentales en la provincia de Tarapoto para abordar la violencia contra la mujer desde una perspectiva jurídica. Para llevar a cabo esta investigación, se adoptó un enfoque cualitativo con un diseño fenomenológico, que permitió explorar las experiencias y percepciones de diversos actores involucrados en este contexto. Los participantes en este estudio comprendieron 10 operadores de justicia, 6 expedientes judiciales relacionados con casos de violencia de género y 5 mujeres que habían sido víctimas de este tipo de violencia. Se emplearon dos guías de entrevista y una guía de análisis documental como instrumentos de recolección de datos. El método comparativo y dogmático se utilizó para analizar la información recopilada. Los resultados refieren que se identificó que la labor del Ministerio Público estaba significativamente limitada en la prevención y persecución de la violencia de género. Además, se constató la ineficiencia en la ejecución de sentencias condenatorias emitidas por el Poder Judicial. También se encontró que las mujeres víctimas de violencia experimentaban una sensación de indefensión y falta de apoyo adecuado por parte de las autoridades. En última instancia, estas estrategias son esenciales para proteger el derecho a la integridad de las mujeres y prevenir la violencia de género en la provincia de Tarapoto, y pueden servir como un modelo para abordar este problema a nivel nacional.
Effect of temperature and Humidity on the Thermal Conductivity λ of Insulation Materials
Authors: Kendzierawska Weronika Anna , Trochonowicz Maciej
Published: January 2024

The aim of this article is to address the influence of air humidity and testing temperature on the thermal conductivity coefficient (λ) of various thermal insulation materials. This group includes wood-based materials, rock wools, heat-insulating renders, climate boards, and lightweight cellular concretes. These materials are used both indoors and outdoors in buildings. Over the course of several years, data were collected from laboratory tests to determine the thermal conductivity coefficient (λ) in relation to increases in temperature and humidity. The obtained results were compared with values provided by the manufacturers of the insulation materials. The aforementioned research was carried out due to the rather high sorption of most materials and thus the possibility of them becoming humid at high air humidity. Because of the very large difference in the thermal conductivity coefficient of water and air, a relatively small increase in the mass moisture content of the materials results in a loss of insulation.

Background/Aims: Endoscopic ultrasound-guided tissue acquisition (EUS-TA) using Franseen needles is reportedly useful for its high diagnostic yield. This study compared the diagnostic yield and puncturing ability of EUS-TA using 22-gauge cobalt-chromium (CO-Cr) needles with those of stainless-steel Franseen needles in patients with solid pancreatic lesions.Methods: Outcomes were compared between the 22-gauge Co-Cr Franseen needle (December 2019 to November 2020; group C) and stainless-steel needle (November 2020 to May 2022; group S).Results: A total of 155 patients (group C, 75; group S, 80) were eligible. The diagnostic accuracy was 92.0% in group C and 96.3% in group S with no significant intergroup differences (p=0.32). The rate of change in the operator (from training fellows to experts) was 20.0% (15/75) in group C and 7.5% (6/80) in group S. Stainless-steel Franseen needles showed less inter-operator difference than Co-Cr needles (p=0.03).Conclusions: Both Co-Cr and stainless-steel Franseen needles showed high diagnostic ability. Stainless-steel Franseen needles are soft and flexible; therefore, the range of puncture angles can be widely adjusted, making them suitable for training fellows to complete the procedure.

Published: January 2024

Background/Aims: This study aimed to compare the safety of the double-guidewire technique (DGT) with that of the conventional single-guidewire technique (SGT) in real-world situations.Methods: A total of 240 patients with naïve papilla who underwent endoscopic retrograde cholangiopancreatography (ERCP) at Daegu Catholic University Medical Center between January 2021 and December 2021 were included. The primary outcome was the rate of post-ERCP pancreatitis (PEP) in the SGT and DGT groups.Results: A total of 163 patients (67.9%) belonged to the SGT group, and 77 (32.1%) belonged to the DGT group. The rates of successful biliary cannulation were 95.7% and 83.1% in the SGT and DGT groups, respectively (p=0.002). In the study group, PEP occurred in 14 patients (5.8%). The PEP rates were not significantly different between the SGT and DGT groups (4.3% vs. 9.1%, p=0.150). In the multivariate analysis, the age of <50 years (odds ratio [OR], 9.305; 95% confidence interval [CI], 1.367–63.358; p=0.023) and hyperlipidemia (OR, 7.384; 95% CI, 1.103–49.424; p=0.039) were significant risk factors for PEP in the DGT group.Conclusions: DGT did not increase the PEP rate in patients with naïve papilla. In addition, the age of <50 years and hyperlipidemia were significant risk factors for PEP in the DGT group.
Nile basin land and water acquisition research agenda: A policy brief
Authors: Enserink Bert , Abazeed Abeer , Elhatow Lama , Muricho Onencan Abby
Published: January 2024

Land and water acquisitions exacerbate the complexity of the water allocation challenges in the Nile region and consequently have contributed to the growing tensions along the Nile River. Smallholders are especially negatively affected by the increase in water use by foreign investors, the loss of access to the commons, and disposition of ownership. This policy brief is a result of a scenario workshop organized in early 2020 in Leiden, the Netherlands, during which some 30 young scientists from a variety of disciplines joined forces to develop four plausible Nile-futures in 2050. The exercise revealed new challenges and potential knowledge gaps in four areas of policy-based research: local innovation and technology, institutional capacity, gover- nance, and investment regulation. Most urgent was the recommendation to have a unified basin- wide university, which would support basin-wide legislation to promote sustainable farming and reduce the negative impacts of land and water acquisitions.

Authors: Trach Dmitrii
Published: January 2024

Ensuring the positive dynamics of the agricultural organizations development taking into account their specifics is an extremely difficult process. It is due to the seasonal nature of the activity and significant dependence on external factors. In this regard, it requires high efficiency of management personnel, which is expressed in the quality of the development strategy being designed, the ability to analyze the current results achieved in their correlation, based on the results of the analysis, to make adjustments to the development strategy and current activities. To solve these problems, a system of indicators is important, which will make it possible to draw objective conclusions on the analysis of the relevant subject of research. In the proposed article, the author uses the correlation method to analyze and study the impact on the profitability of sales of such indicators as labor productivity, return on capital of production assets, turnover of working capital, labor capital ratio, current liquidity ratio, investments per 1 hectare of agricultural land. For the first time, the object of the study was twenty peasant farms in the region. As a result of the analysis, a forecast of the level of management efficiency dependence of on selected factors was made, calculated on the database of the studied enterprises in the region. The use of the systematic analysis of correlations will make it possible to make adjustments to current activities and thus ensure its positive dynamics and achieve the ultimate goal of ensuring financial stability.

Published: January 2024

Phase change materials (PCMs) with superior cooling capacity and temperature equalization have great potential to mitigate thermal accumulation, benefiting the safety of electric vehicles (EVs) drivers. Although the composite phase change materials (CPCMs) with organic form stable addition can prevent leakage, they are still restricted in battery module due to easy flammable performance. Another challenge is that the inorganic flame retardants always distribute unevenly in organic CPCMs. Herein, to overcome the drawback of uneven additives dispersion within paraffin, we proposed a novel CPCM with inorganic flame-retardant and organic form stable material, composed of Paraffin/Styrene-Ethylene-Butylene-Styrene/AmmoniumPolyphosphate/Silicon dioxide/Carbon micro-nano aggregates (PS/APP/SiO2@C). The prepared material exhibits anti-leakage property with 99.5% mass retention after heating for 10 h at 70°C, and the smoke generation rate is only 0.01 m2·s-1. The total heat releasing time is extended to 700 s, three times longer than that of PS. As for battery thermal management system, the maximum temperature and the temperature difference of battery module with PS/APP are 81.2°C and 5.6°C at 5 C discharge rate, respectively. In comparison, the maximum temperature and maximum temperature difference can be controlled to 58.5°C and 1.5°C, respectively, without heat accumulation during the twenty cycles. It indicates that the temperature is lower than the critical one to avoid thermal runaway of EVs. Therefore, this study presents CPCMs as an advanced thermal management approach that can enhance the thermal safety of battery packs, resulting in a significant impact on millions of drivers of EVs around the world.

La carga parasitaria gastrointestinal en ovinos (Ovis aries L.) es un factor que limita su producción en las zonas tropicales y subtropicales, ya que la aplicación de productos químicos para su control representa un alto costo. El objetivo de este estudio fue comparar la resistencia genética y alimenticia con la carga helmíntica en corderos de las razas Katahdin y Pelibuey en el sureste del trópico mexicano. Se utilizaron corderos Kata hdin y Pelibuey con media sangre de cruzas Dorper, de tres a cuatro me ses de edad, con un peso corporal de 20.09 ± 2.88 kg. Los tratamientos fueron: 1) Pelibuey con alta suplementación (PAS); 2) Pelibuey con baja suplementación (PBS); 3) Katahdin con alta suplementación (KAS) y 4) Katahdin con baja suplementación (KBS). La suplementación alta con sistió en 1% de su peso vivo en grano de maíz amarillo cada día; para la suplementación baja se suministraron 100 g del mismo grano por día.  Se determinó la condición corporal (CC) y el índice FAMACHA mediante la prueba de Wilkoxon. Se evaluó ganancia diaria de peso (GDP), huevos por gramo de heces (HGH) y hematocrito (H); además se identificó el género de los parásitos gastrointestinales. Se utilizó un diseño completamente al azar con arreglo factorial 2 x 2. No se encontraron diferencias para ningu na variable por efecto de raza (p>0.05). Sin embargo, la suplementación afectó (p<0.01) la GDP: 4.64 ± 2.23 kg con alta suplementación y 2.43 ± 2.34 kg con baja suplementación. El H no mostró diferencias entre razas (p>0.05). La raza Katahdin fue más pesada que Pelibuey (p<0.0001): en KAS, el peso corporal fue de 22.96 + 0.36 kg; y en KBS fue de 22.06 + 0.33 kg. Los corderos con alta suplementación fueron más pesados que los que tuvieron baja suplementación (p<0.0001). En PAS, el peso corporal fue de 19.90 + 0.33 kg, y en PBS fue 17.70 + 0.38 kg. Se encontró correlación negativa (p=0.01) entre las variables CC-HGH (r=-.241) e índice FAMACHA HGH (r=-.198). Los únicos géneros presentes fueron Haemonchus spp. y Trichostrongylus spp.

El estudio se realizó en el Campus Buenavista de la Universidad Au tónoma Agraria Antonio Narro en Saltillo, Coah., México, del 12 de di ciembre de 2012 al 14 de febrero de 2013. Se evaluó la producción y la calidad (acidez, proteína y grasa) de leche y el peso de cabras y crías, en cabras Murciana-Granadina alimentadas con triticale hidro pónico, sustituyendo el heno de alfalfa en 0, 20 y 40%. En todos los tra tamientos se proporcionó 30% de alimento concentrado (Apileche®).  Se utilizó un diseño experimental completamente al azar, cada trata miento estuvo compuesto por cinco cabras (n=5). No se encontraron diferencias (p>0.05) en la producción de leche, pero sí (p<0.0001) en la calidad: el testigo presentó la mayor acidez (2.05 °D), los trata mientos con sustitución de 20 y 40% de heno de alfalfa fueron esta dísticamente iguales con 1.65 y 1.60 °D expresados al 10%. También hubo diferencias (p>0.05) en la acidez en relación con los muestreos:  el primero fue el más bajo, con 1.60 °D; el segundo muestreo tuvo 1.78 °D; el cuarto, 1.80 °D, y el tercer muestreo, 1.88 °D. Los conte nidos de proteína y grasa, así como el peso de las cabras no mostra ron diferencias (p>0.05) entre tratamientos. En el peso de las crías, el testigo mostró el mayor peso (p<0.001) durante la prueba (10.03 kg), seguido del tratamiento con la suplementación de 40% de heno de alfalfa (8.85 kg), las crías alimentadas con la suplementación al 20% tuvieron el menor peso (7.85 kg). La sustitución de alfalfa por triticale hidropónico no aumentó la producción, ni los contenidos de proteína y grasa, pero sí afectó la calidad de la leche al bajar el nivel de acidez.

Published: January 2024

Se evaluó el efecto de la suplementación alimenticia de toretes charolais con subproductos de cervecería sobre su comportamiento productivo. Se utilizaron 18 toretes, los cuales se desparasitaron, vitaminaron y se distribuyeron en seis tratamientos que resultaron de la aplicación de tres niveles de Masilla húmeda de cervecería (MC), y dos niveles de levadura inactiva de cervecería (LC) durante tres etapas de crecimiento. Las variables evaluadas fueron: Consumo diario de materia seca (CDMS), Ganancia diaria de peso (GDP) y Conversión alimenticia (CA). Se utilizó un diseño completamente al azar con arreglo factorial A x B, en donde A = niveles de MC (0, 10 y 20 %) y B = niveles de LC (0 y 10 %). En la primera etapa solo se encontró diferencia significativa (P<0.05) en el CDMS con la interacción de MC x LC; se observó una disminución con la combinación de 20 % de MC y 10 % de LC. La concentración de colesterol disminuyó (P<0.05) con la LC. Durante la segunda etapa se observó un efecto de interacción MC x LC sobre el CDMS y sobre la GDP: ambas variables disminuyeron (P<0.05) con la combinación de 20 % de MC y 10 % de LC. La CA y el perfil sanguíneo no se afectaron (P>0.05) con la suplementación de ambos subproductos durante la segunda y tercera etapa. Sin embargo, en la tercera etapa se registró un mayor CDMS (P<0.05) con la inclusión de 10 % de LC en la ración. De lo anterior se concluye que el posible efecto asociativo entre los subproductos de cervecería radica en el efecto regulador que ejerce la LC sobre los decrementos en el CDMS provocado por la MC, aún así, los subproductos representan una opción para la alimentación de toretes de engorda.

Published: January 2024

Se realizó un experimento con el objetivo de evaluar el efecto de la incorporación de tres niveles de zeolita tipo clinoptilolita a la dieta de cerdos en un programa de alimentación de tres etapas, en base a su comportamiento productivo y perfiles metabólicos. Se utilizaron 42 cerdos: 24 machos castrados y 18 hembras de cruzas tipo comercial Yorkshire, Hampshire y Landrace de 13 a 99 kg de peso vivo. Los tratamientos se diseñaron de acuerdo a la combinación de niveles de los factores: etapa de producción (inicio, crecimiento, finalización) y nivel de inclusión de zeolita en la dieta (0, 2, 4 %). Se utilizó un diseño experimental de bloques al azar. El experimento tuvo una duración de 114 días y se realizó en la Granja Porcina de la Universidad Autónoma Agraria Antonio Narro (UAAAN), localizada en Saltillo, Coah., México. No se encontraron diferencias (P>0.05) para Ganancia de peso, pero si para Consumo y Conversión alimenticia (P<0.05). La zeolita al 4 % incrementó el consumo, pero redujo la Eficiencia alimenticia, en tanto que al 2 % mejoró la Conversión alimenticia sin aumentar el consumo de alimento. La concentración de glucosa en suero aumentó en las etapas de crecimiento y finalización, pero se mantuvo constante en iniciación (P<0.05). La concentración de urea y creatinina disminuyó en las tres etapas de producción (P<0.05). Las proteínas totales tuvieron una tendencia a disminuir en la iniciación y a elevarse en crecimiento y finalización (P<0.05). El colesterol y los minerales no fueron afectados (P>0.05). Se concluye que la adición de zeolita en la dieta no mejora el aumento de peso, ni afecta el metabolismo de minerales y grasas, pero si al consumo de alimento, la conversión alimenticia y los procesos enzimáticos involucrados con el metabolismo de carbohidratos y proteínas.

The main source of data about possible future climate change over the Czech Republic studied within the project PERUN is a series of Aladin-CLIMATE/CZ model simulations driven by the global climate model CNRM-ESM2-1. Other available model simulations, in particular the CMIP5 and CMIP6 global climate models, Euro-CORDEX regional climate models, and other new simulations at high horizontal resolution, will be used to estimate the uncertainties in the climate change scenarios. This paper presents examples of such uncertainty analysis.

Hydrological methods based on the analysis of data from a large sample of catchments with different characteristics (large-sample hydrology; comparative hydrology) allow a comprehensive analysis of the hydrological regime and thus a description of hydrological variability and change in the components of the water balance. These methods provide insight into hydrological processes that are shaped by environmental and climatic factors and allow more general conclusions to be drawn. However, in addition to climate and runoff data, catchment attributes, such as geology, soils, topography and vegetation, are essential for effective hydrological behaviour analysis. For these reasons, the global hydrological community has recently developed a number of freely available large-scale datasets known as CAMELS (Catchment Attributes and MEteorology for Large-sample Studies), which provide catchment attributes, as well as hydrological and meteorological time series, in a comparable structure at national scales. The aim of this contribution is to present the current state of preparation the CAMELS database for Czechia (CAMELS-CZ) as a reference data platform for analysis and modelling, using large-sample of catchments.
Change in precipitation distribution as temperature rises expressed in diagnostic and prognostic data
Authors:   Ústav fyziky atmosféry AV ČR v. v. i., Sokol Zbyněk , Řezáčová Daniela
Published: January 2024

We summarize the main results that show how the distribution of precipitation changes with increasing temperature. Hourly rainfall totals from 97 rain gauge stations in the Czech Republic for the years 1997 to 2019 are used for the evaluation. Ground temperature, ground dew point temperature and temperature at the lifting condensation level are used to express the temperature change. The results show how an increase in temperature and a corresponding increase in saturation humidity (CC scaling) affects the distribution of precipitation in the study area. In general, the increase in precipitation as a function of observed temperature is clearly evident for the upper quantile values, but only for certain temperature intervals. It confirms the findings of other studies. In this paper, data from reanalyses performed by the ALADIN-CLIMAT/CZ model are treated similarly to the measured data.
Number of Sultry Days in the Territory of Slovakia
Authors:   Slovenský hydrometeorologický ústav, Szabóová Kristína
Published: January 2024

Sultriness is formed by the interaction of several weather factors. It is the state of the atmosphere when the water vapor pressure exceeds 18.7 hPa. This condition has adverse physiological effects on plants, animals and especially on the human body. For this reason, in this research, emphasis was placed on the time evolution of sultriness at the meteorological station Hurbanovo in the Slovak Republic. The paper will examine the 40-year period (1981–2020). The study is a continuation of the work of Štefan Kveták, who examined the previous 30-year period (1951–1980). We hypothesized that the number of sultry days is also increasing due to climate change. The basis of the whole assumption was hourly data from meteorological stations in the database of the Slovak Hydrometeorological Institute. As the scientific goals of the project, we preferred the categorization of sultriness according to various criteria, the evaluation of their frequency and time trends of occurrence, and we compared their development with the previous period.

Published: January 2024

To analyse the regionalisation of the territory of the Czech Republic in terms of risk and changes in the frequency of extreme events, a first set of "risk characteristics" describing selected categories of hazardous events – heat, frost, drought, torrential rains, storms and fires – was prepared. So far 12 characteristics have been tested for the period 1991–2020, some of them for multiple thresholds. For example, the number of hot days with a maximum temperature of 34 °C or more for a limit of 3 and 6 days on average in a given period, or the average daily maximum temperature in the extended growing season April–October for a limit of 21 °C, etc.
Historical development of groundwater levels in selected areas

Published: January 2024

Fluctuations in groundwater levels in the Czech Republic are characterized by a different proportion of seasonal fluctuations, a long-term trend in fluctuations in groundwater levels and the speed of reaction to significant recharge episodes. Within one hydrogeological region with the same hydrogeological conditions, there are thus wells with very different fluctuations in groundwater levels. It is therefore very difficult to describe one hydrogeological region with one type of characteristic fluctuation of groundwater levels, which describes the dynamics of fluctuations of groundwater levels in the hydrogeological region. On the other hand, hydrogeological regions at different distances from each other in different geological environments have very similar fluctuations in groundwater levels. For these reasons, all wells of the ČHMÚ observation network were divided into 4 main groups: a group with predominant seasonal fluctuations in the groundwater level, with a long-term trend of fluctuations in the groundwater level, a group of long-term affected wells in the hydrogeological regions of the deep layer, and a group of wells that were excluded from the evaluation groundwater levels. The above-mentioned classification made it possible to compare the development of groundwater levels in different areas with an emphasis on the behaviour of groundwater levels in recent years.
Start of the Information System on the state and development of drought on the territory of the Czech Republic
Authors:   Český hydrometeorologický ústav, Pecha Martin , Čekal Radek
Published: January 2024

No official warnings regarding the drought onset and its development had been issued in the Czech Republic until 2022. The amendment to the Water Act requires the Czech Hydrometeorological Institute (CHMI) to regularly inform the selfgovernments, such as the Regions and Municipalities with Extended Powers, about the risk of drought onset. In 2022, an information (alert) system was created to inform (alert) about the drought onset and development on the territory of the Czech Republic. This short paper introduces the whole system, including the methodology.
Comparison of SPEI drought indexes with three different statistical distributions based on data from Slovakia
Authors:   Slovenský hydrometeorologický ústav, Slavková Jaroslava
Published: January 2024

The Standardized Precipitation Evapotranspiration Index (SPEI) is among the most commonly used indicators for assessing meteorological drought. SPEI represents the normalized value of the water balance D (where D = precipitation − evapotranspiration) for a specific station and time period. Normalization is carried out based on the statistical distribution of D calculated for a chosen reference period (typically recommended to be 30 years or longer). The calculation process of SPEI lacks a strict definition, allowing certain parameters to be user-dependent. For example, the user can determine the index's duration, the method used for potential evapotranspiration calculation, the reference period, and the statistical distribution applied to the water balance parameter (D). These choices can impact the resulting index value. This study compares SPEI indexes calculated with three different statistical distributions: Log-logistic, Generalized Extreme Value, and Pearson III. Our evaluation is based on three criteria: a) The frequency of cases where the model cannot calculate the parameters of the selected statistical distribution; b) The number of cases where the final SPEI values do not conform to a normal distribution (the assumption is that correctly chosen statistical distribution for D should yield normally distributed index results); c) The incidence of overestimated extremes (|SPEI| > 6).

Published: January 2024

The aim of the contribution is to evaluate how hydroclimatic variables change due to the influence of advancing climate change and whether their change is reflected in the change in the water quality of surface streams. To evaluate the impact of climate change, four streams in the Sázava River basin were selected – Šlapanka, Sázavka, Jankovský potok and Chotýšanka. This is a watershed of a typically rural character, where the dominant source of pollution is agriculture. Data series of hydroclimatic parameters and water quality parameters provided by the ČHMÚ and Povodí Vltava s.p. were available. The selected parameters were: air temperature, total precipitation, height of snow cover in the basin and water temperature, conductivity, ammonia nitrogen, nitrite nitrogen, nitrate nitrogen, phosphate phosphorus and total phosphorus in streams. Data were analysed using regression analysis, correlation coefficients, and the Mann-Kendall trend test. Data analysis showed that hydroclimatic parameters changed in the observed period. The air temperature increased, its increase was proven by the Mann-Kendall trend test (Sázavka and Šlapanka River basin). Furthermore, the number of tropical days increased, the height and duration of the snow cover decreased. No trend was found in the rainfall totals data. There was a slight increase in stream water temperature, but this increase was not confirmed by the Mann-Kendall trend test. Nitrate concentrations were high in all selected streams and their concentrations stagnated or slightly decreased. Phosphate phosphorus concentrations also decreased. Dependency analyses showed that in selected river basins nitrates come from areal sources of pollution, while phosphates rather come from diffuse point sources of pollution. The planned management of activities in the river basin is therefore necessary to adapt to the character of pollution sources.

Published: January 2024

For a targeted screening of organic micropollutants in the surface waters of the Czech Republic, a passive sampling technique designed for polar organic substances was used. The results from two sampling campaigns in 2021–2022 as well as the results obtained in previous years (2012–2020) in 43 surface water profiles were included in the assessment. Various substances from the groups of pesticides, pharmaceuticals, bisphenols, benzotriazoles, perfluorinated substances, illicit drugs, personal care products including UV filters, flame retardants, etc. were monitored. Using the targeted screening of 412 polar micropollutants in 2012–2020, the occurrence of 342 substances (83% of the monitored substances) was proven. 205 substances of 252 monitored ones (81%) were found in years 2021–2022.
