title: Spatial statistics to evaluate the relationship between basic sanitation, HDI and remnant vegetation in the State of Goiás, Brazil

description: Abstract This study presents the results of the spatial clustering of the 246 towns of the State of Goiás, Brazil, considering basic sanitation data, human development index and land use. Monthly data related to E. coli, turbidity and apparent color from 140 local sources between 2005 and 2009 were also analyzed and compared with the vegetation cover and precipitation. For the preparation of spatial clustering analysis, the Getis-Ord index was used and it was applied to sanitation, Human Development Index (HDI) and vegetation cover index (Landsat 7 ETM+ images acquired in 2002). It was observed that there is a strong correlation (p&lt;0.05) between areas that have higher rates of sanitation with the regions that have the highest HDI levels, and an inverse relationship with the occurrence of remaining vegetation cover index. There was a change in water quality among towns that have greater intervention in land use, especially in the North of Goiás, Brazil, which has the largest remaining vegetation areas and showed better values for apparent color, turbidity and E. coli than the other municipalities. In addition, concentrations of these parameters increased with rainfall, which in the State of Goiás, Brazil, occurs primarily between November and April.

title: Effect of carbon dioxide and sunlight on algae biomass produced in laminar photobioreactor

description: Abstract This work measured the influence of CO2 supply and photosynthetically active radiation on microalgae production in the laminar photobioreactor. In order to accomplish this, the production and concentration of nitrogen and phosphorus in the biomass collected from each of the 36 subdivisions of the system was analyzed weekly. Additionally, productive and energetic efficiencies were determined by estimating biomass production. The artificial CO2 supply affected biomass production, increasing the productivity from 3.9 to 27.0%. The photosynthetically active radiation was related to the production of biomass, which varied up to 60.5%, producing between 1.42 and 2.28 g m-2 d-1. The nitrogen concentration in the biomass was not influenced by any of the evaluated factors; nevertheless, the phosphorus was influenced by both factors. The productive and energetic efficiencies had similar influence, ranging from 0.28 to 0.44 g mol-1 and from 2.12 to 3.34%, respectively.

title: Structure of herbaceous vegetation in riparian landscapes in Southern Santa Catarina, Brazil

description: Abstract The structural and ecological characteristics of herbaceous vegetation make it sensitive to environmental changes, acting as environmental quality indicator. However, studies of the herbaceous community are as yet rare in neotropical regions. This paper describes the floristics and phytosociology of terrestrial herbaceous vegetation in the riparian forest of seven rivers near the town of Urussanga, Southern Santa Catarina, Brazil, and also analyzes and quantifies the status of scientific knowledge related to terrestrial herbaceous vegetation in Brazil. The study selected 320 sampling units of 4 m²; species were identified and related data regarding phytosociological parameters were collected. The sampling discovered 58 taxa, of which 38 belonged to angiosperms and 20 to ferns, distributed in 25 botanical families. Poaceae was the most prevalent with 11 species. Structurally, Goeppertia monophylla (Vell) Borchs and S. Suárez, Blechnum brasiliense Desv and Heliconia farinosa Raddi stood out. The most common form of life was reptant hemicryptophyte. The results indicate a richness of terrestrial herbaceous vegetation adapted to the climatic conditions of a riparian forest, contributing to diversity of the regional flora. Regarding scientific production, 50 papers were found in electronic databases (1990-2015), with 2011 as the year with greatest scientific production regarding terrestrial herbaceous vegetation. Nevertheless, despite the low number of indexed papers found regarding terrestrial herbaceous vegetation, the amount tends to increase due to advancements in database access technology.

title: Influence of the number of vulnerability classes in determining morphometric susceptibility to flooding

description: Abstract Watershed morphometry is an important tool to diagnose susceptibility to flooding. This diagnosis can guide the planning and implementation of mitigation measures to avoid flooding damage. The objective of this work was to study flooding susceptibility in Espírito Santo Stream Basin (ESSB), located in the municipality of Juiz de Fora, Minas Gerais, Brazil, based on its morphometric characterization using two, three and five classes of vulnerability. In order to accomplish this, the basin was divided considering two levels of detail: in the first, less-detailed level, three sub-basins were generated; and in the second, more-detailed level, 65 watersheds were generated. Morphometric susceptibility to flooding was evaluated in these study units and the results were compared using the K-means and Fuzzy C-means clustering techniques. The results showed that the number of classes adopted affects the result of classification vulnerability, suggesting that cluster validation criteria can be used to delimit the choice of the number of classes to be adopted. Groups formed only by morphometric similarities differ from those obtained by the methodology based on classification of areas susceptible to flooding, since the methodology for susceptibility analysis transforms the numerical values of each morphometric parameter in a class of susceptibility.

title: Water Quality Index and suitability for bathing of Bica Stream, Portalegre, RN, Brazil

description: Abstract Water quality is characterized by physical, chemical and microbiological parameters, which are constantly subject to the interference of nature, the ecosystem and human land-use activities. In Rio Grande do Norte State, Brazil, the improvement of water quality requires attention, considering that the region loses a significant portion of its waters through high evaporation rates. In this context, the town of Portalegre has a complex landscape formed by perennial springs, upper swamps and waterfalls. Considering the uniqueness of the area, this research characterized the water quality of Bica Stream, which flows through the watershed area located on the north side of the city, and is very popular for leisure activities. This research analyzed the Water Quality Index (WQI) at three points of the Bica Stream, as well as the Pinga Waterfall's suitability for bathing, as it is frequently used for this purpose. The results show that the water quality is better at the spring of Bica Stream, with a WQI classified as "regular". The other parts of the stream were classified as "bad". The waterfall water was classified as excellent for bathing.

title: Detection of Giardia spp. cysts and Cryptosporidium spp. oocysts in untreated water collected from treatment plants in Blumenau, Santa Catarina State, Brazil.

description: Abstract Giardia spp. and Cryptosporidium spp. are water-borne pathogenic protozoans spread through fecal-oral transmission which cause several health problems, to include gastrointestinal diseases associated with the consumption of contaminated water. There are limited data regarding the occurrence of these protozoans in surface waters in southern Brazil. The aim of this study was therefore to investigate the presence of cysts and oocysts in untreated water collected from water treatment plants in Blumenau, Santa Catarina State, Brazil. The methodology employed to study the protozoans was filtration through mixed cellulose ester membranes followed by the immunofluorescence reaction using the Merifluor(r) kit. Microbiological analysis was conducted using the Standard Methods for the Examination of Water and Wastewater and multi-parameter probes were used for the physico-chemical analysis. Cysts of Giardia spp. were found in 23.19% of the samples and oocysts of Cryptosporidium spp. in 7.24% of the samples (n=67). All of the samples analyzed were contaminated with Escherichia coli and 11.76% of the untreated water samples had turbidity values higher than the recommended limit. In the case of the treated water samples, 23.52% had turbidity values above the limit established by legislation (Portaria MS 2914/2011). The detection of pathogenic protozoans in the untreated water at the treatment plants highlights the importance of adopting preventative measures, such as the protection of areas where water is present and adequate treatment of domestic sewage, in order to reducing the risk of protozoan transmission via potable water.

title: Anaerobic biodigestion of sugarcane vinasse under mesophilic conditions using manure as inoculum

description: Sugarcane vinasse is one of the most polluting residues produced by Brazilian ethanol industries, mainly because of its harmful effects on the environmental, such as high organic matter load and acidity. Anaerobic digestion is a highly efficient wastewater treatment method that could potentially be used to treat sugarcane vinasse. This study examined the anaerobic biodigestion of sugarcane vinasse in mesophilic conditions (30 - 45°C) by varying the inoculum concentration (0.5 to 5.5%) and pH (6 - 8). Changes of Chemical Oxygen Demand (COD), total solids content, and yield and composition of biogas after the biodigestion of the vinasse were assessed. The vinasse was efficiently digested under mesophilic anaerobic conditions over a 23-day Hydraulic Retention Time (HRT) and a 5-day acidogenic phase with a consequent reduction of COD (54 - 83%) and total solids (52 - 87%). Statistical analyses at a confidence level of 95% suggested that temperature, pH and inoculum concentration did not influence on the anaerobic biodigestion of the vinasse. The optimal operating parameters were found to be temperatures of 30 - 35°C, inoculum concentration of 0.5% and pH of 6 - 7. The results emphasize the promising use of the treated sugarcane vinasse as a biofertilizer for agriculture, indicating that the anaerobic digestion process is an excellent alternative for Brazilian ethanol industries.

title: Photocatalytic degradation of an organophosphorus pesticide from agricultural waste by immobilized TiO2 under solar radiation

description: This paper describes solar heterogeneous photocatalysis using immobilized TiO2 applied in the treatment of agricultural waste resulting from the application of commercial formulations of methyl parathion. The disappearance of the insecticide, as well as the formation of its metabolite, was monitored by high-performance liquid chromatography-tandem mass spectrometry (LC-MS/MS), while mineralization efficiency was monitored by measurements of total organic carbon (TOC). Toxicity studies were performed using the microcrustacean Artemia salina. The TOC removal efficiency by photocatalytic process was 48.5%. After 45 minutes of treatment, the removal efficiency of methyl parathion was 90%, being completely mineralized at the end of treatment. The formation and removal of the metabolite methyl paraoxon was observed during the photocatalytic process. The photocatalytic treatment resulted in increased microcrustacean mobility, indicating a reduction of acute toxicity.
