title: Environmental monitoring analysis of municipal solid waste incineration in Europe and the needs for changes in brazilian legislation

description: Abstract Incineration is a solid waste treatment technology whose main purpose is to reduce the volume and mass of the waste to be disposed of in landfills. The incinerators built in the last decades bring the possibility of energy recovery from waste, in the form of steam and/or electric energy. However, this technology still raises questions about possible environmental impacts related to its emissions. Incineration is regulated in Europe through specific legislation which, among other issues, requires the disclosure of environmental monitoring data for incinerators. In the present work, atmospheric emissions data from incinerators associated with the Confederation of European Waste-to-Energy Plants (CEWEP) are analyzed by searching the websites of the respective incinerators, scientific articles and technical reports. Monitoring data on all continuous and periodic measured pollutants defined in the legislation in time series from 2010 to 2017 were analyzed. All annual average emission values of the incinerators analyzed were below the limits defined by the European Union's Directive, with little variation over the observed years. The comparison of European with Brazilian emission standards shows the need for a change in local legislation on incineration so that, if this technology is implemented in Brazil, it will operate within safe limits, with a guarantee of minimizing impacts on the environment and surrounding populations.

title: Biological treatment of mine drainage — scenario updated, perspectives, and recommendations for future works

description: ABSTRACT Rocks containing metal sulfides be can oxidized biologically or chemically. Chemolithoautotrophics prokaryotes and Fe3+ catalyze this process. The mining activities also accelerate the process for creates metal sulphides tailings with a big contact surface. The leached formed is called Mine Drainage (MD) whose composition is rich in sulphate, hydrogen ions and inorganic chemical contaminants such as Fe, Zn, Mn, Cd, Ni, As e Al. Currently, in order to remove these pollutants, the main treatment used is the addition of alkaline reagents. However, the method has limited efficiency, high cost with input reagents and generates wide amounts of toxic solid residues with high solubility. The sulphide reducing bacterias (RSB) can oxidize organic matter generating sulphide. Some metabolic pathways consume H+ neutralizing the pH. The sulphide formed can react and precipitate inorganic pollutants, allowing their recuperation from the liquid phase. The use of industrial and urban by-products containing different carbon sources have been investigated as an electron donor in the MD treatment. The diverse microbial consortia synergic acting can present bigger efficiency in the presence of mixed carbon sources, besides lower cost in relation to the pure matter. Here will be detailed the biological treatment about which and how the variables of the system can influence the microbial activity and relevant molecules to the treatment. After is described the current situation of the research about alternative carbon sources. New carbon sources whose are a by-product of the expanding industry presenting good feature to anaerobic degrading are suggested. The by-product potential is described from the point of view of sustainability, and waste management.

title: Microbiological quality of water and Perna perna (Linnaeus, 1758) mussels cultivated in Piúma, Espírito Santo, Brazil

description: ABSTRACT This study aimed to verify the microbiological quality of water and mussels cultivated by the Piúma Farmers Association (Associação dos Maricultores de Piúma — AMPI), Espírito Santo, Brazil. Seven samples of water and mussels were collected monthly from October 2016 to May 2017. The mussels were collected from the long lines of the AMPI, and in each month 40 mussels Perna perna and 100 mL of water were sampled from the site. The collected material was sent to the laboratory for duplicate microbiological analysis, Most Probable Number of Total (CT) and Thermotolerant (Ctt) coliforms, presence or absence of Salmonella sp and number of Staphylococcus aureus colony forming units. The results showed that the number of Ctt in the water samples in January was higher than that allowed by Resolution 357 of the National Environment Council (Conselho Nacional do Meio Ambiente — CONAMA). The levels of Ctt and Staphylococcus aureus in mussel meat were within the acceptable range by the Brazilian National Environment Council (Agência Nacional de Vigilância Sanitária — ANVISA) Resolution RDC No. 12. However, colonies with characteristics of Salmonella sp were found in December and March in the mussels, making it impossible to sell and consume. This period coincides with a high flow of tourists in the municipality. Finally, it is recommended to perform microbiological analyzes continuously, especially in the summer, where there are a lot of tourists in the city of Piúma, period that showed the presence of Salmonella in the meat of mussels and Ctt levels in water above the allowed current legislation.

title: Degradation of the EBR-CFRP strengthening system applied to reinforced concrete beams exposed to weathering

description: Abstract Little is known about the behavior and durability of strengthening systems applied on concrete substrata and the possible loss of performance due to the degradation of the intervening materials by the structure’s natural aging process and exposure of the externally strengthened elements to aggressive environments. In this context, the present work presents an experimental analysis of the behavior of reinforced concrete beams strengthened with Carbon Fiber Reinforced Polymer (CFRP), applied according to the Externally Bonded Reinforcement (EBR) technique, maintained in a laboratory environment (indoor and protected) or exposed to weathering (outdoor exposure). In addition, specimens of the intervenient materials were also molded and exposed to the same environmental conditions as the beams. The results indicate that weather-exposed epoxy adhesives present reductions up to 70% in their mechanical properties after exposure, while the CFRP composite properties remain similar. It was also found that the strengthening system provided 50% and 28% increments in the load-carrying capacity and stiffness of the elements, respectively. However, the tests conducted after 6 months of weathering exposure showed a 10% reduction in the load-carrying capacity of the strengthened elements.

title: Evaluation of rainwater quality stored in cisterns of concrete plates and polyethylene in a municipality in the semi-arid of the Paraíba State

description: ABSTRACT An evaluation of rainwater stored in cisterns in the semiarid region of the state of Paraíba is presented in this paper. Water samples from concrete plates cisterns (CPLAs) and polyethylene ones (CPOLs) were collected and analyzed in order to verify whether there are differences between water quality parameters in the two types of cisterns. Statistical tests were applied to detect whether there are differences between the physical and chemical parameters pH, temperature, turbidity, electrical conductivity, total dissolved solids, dissolved oxygen, alkalinity, color, hardness, chloride, ammonia, sulfate, salinity, and nitrate. Analyses of the variability of the parameters and verifications of compliance were also carried out in accordance with the Ministry of Health Consolidation Ordinance 05/2017, which establishes water potability standards. Among the parameters analyzed in the water samples from the CPLAs and CPOLs, those that confirmed the hypothesis of equality of means were chloride, dissolved oxygen, and sulfate. There were higher alkalinity and salinity variability in CPLAs waters in relation to these parameters in CPOLs. Almost all physicochemical parameters were in compliance with the ordinance, and the exception were color, pH, and turbidity.

title: Hydrometeorological conditions in the semiarid and east coast regions of Northeast Brazil in the 2012-2017 period

description: Abstract Various studies have identified that between 2012 and 2017, Brazil’s semiarid region suffered severe drought. However, few studies have analyzed whether this drought also affected the eastern coastal region of Northeast Brazil (ENEB). Therefore, the objective of this work is to identify rainfall anomalies in these regions and verify the hydrometeorological impact on reservoirs in the 2012-2017 interval. For this purpose, we used precipitation data and atmospheric variables in the period from 1981 to 2017 to investigate the rainy season and associated dynamic patterns, as well as the consequences of these mechanisms on the variation of the water parameters of important reservoirs. The results indicated that rain events in the ENEB during 2012-2017 presented similar climatological behavior, without the characteristic of a drought event as observed in the semiarid region. The meteorological analyses showed that the combination of convergence with moisture over the Atlantic Ocean possibly favored greater frequency of shallow convective rainfall in ENEB, an important factor to explain the absence of generalized negative anomalies in the region. As a consequence, the reservoirs did not suffer from water collapse, unlike in the semiarid region.

title: Influence of hemodialysis blood flow rate on the thrombogenic potential in patients with central venous catheters

description: Abstract In this study we apply methods to determine the tendency for thrombus formation in different central venous catheters (CVC) models associated with flow rate variation. To calculate the thrombogenic potential, we proposed a new numerical model of the platelet lysis index (PLI) equation. To compare the results of PLI and flow rate in different models of catheters, numerical calculations were performed on three different tips of CVC. The results showed that the PLI increases as a power function of the flow rate independent of the type of CVC. This study evidenced that the higher the blood flow rate used in the catheter, the greater the potential for thrombus formation. The PLI computed at the catheter outlet presented higher values when compared to the values computed at the vein outlet indicating that the blood flow through the CVC arterial lumen presents a proportionally larger thrombogenic potential when compared to the blood flow that leaves the vein towards the atrium. This finding may have consequences for clinical practice, since there is no specific flow value recommended in the catheter when the hemodialysis machine is turned on, and with this equation it was possible to demonstrate the thrombogenic potential that the flow rate can possibly offer.

title: Analysis of drought frequency using clustering technique and probabilities functions

description: Abstract The objective of this work was to adjust probabilities density function to drought indexes: Severity and Duration in three sub-regions of Brazilian semi-arid (BSA). For that, were used data of total monthlies precipited of 320 rain stations for period from 1984 to 2014, kindly provided by the Agência Nacional de Águas (ANA). Were used the “Run Method” and total monthlies precipited for obtain the monthlies indexes that characterize the drought: Severity (mm) and Duration (months). We then used the Cluster Analysis technique to regionalize theses characteristic drought indexes. The following step was to adjust probabilities density functions to drought indexes: Severity and Duration in three sub-regions of in the Brazilian semi-arid (BSA). The Gamma bi-parametric, Generalized Extreme Value (GEV) and Logistics functions were better adjusted to the indices of drought Severity (mm) and the GEV, Weibull tri-parametric and bi-parametric models, were better adjusted to drought indices Duration, to the homogeneous sub-regions 1, 2 and 3, respectively.
