This research was conducted in Southern Brazil to determine the wildlife dynamic in a highly human-modified landscape using Oxygen-18. The map shows the location of samples of terrestrial carnivores, herbivores, and omnivores collected for analysis. The isotopic analysis showed that wildlife depends on artificial water reservoirs for their drinking habits. This emphasizes the need to improve sanitary control of these manmade ponds to protect natural fauna in the study region.

Results from research designed to investigate the efficiency of electrocoagulation in removing COD, turbidity, and apparent color from healthcare waste (HCW), these graphs show the percent removal of these parameters as a function of electric current, electrode distance, and hydraulic retention time. One of the conclusions associated with these results is that the high removal of turbidity, COD, and apparent color showed that electrocoagulation was effective for treating gas scrubber effluents.

This series of maps shows the enrichment, geoaccumulation, potential ecological risk, and distribution of metals results in the Aguada Blanca Reservoir in southern Peru. This reservoir is the main source of drinking water for more than one million people in the city of Arequipa. It can be observed that most of the elements present an increase in their concentrations as they approach the reservoir outlet, which could indicate water quality problems due to inappropriate sediment removal in the last 30 years.

This study was intended to evaluate the risks of cascading dams in rural areas where they are commonly built to support irrigation, animal watering, or other purposes. These hydrological structures can cause significant damage when they collapse under heavy precipitation conditions. The figure shows the resulting classification from low to high Hazard Potential (DPA for its acronym in Portuguese) considering them isolated, under current Brazilian law, and the proposed Cascade Classification. The results emphasize the need for a preliminary safety assessment of the dam with special attention to small dams in cascade since accidents in the smaller dams are usually not reported even though they occur more frequently. And only a few countries have specific legislation or criteria for evaluating the safety of these structures.

In this research, the use of laterite in natura for the removal of phosphorus in domestic effluents was investigated. The three parts of this graphic illustrate the interaction of the variables used in the study as follows: a) dosage of adsorbent material and pH; b) pH and contact time; and, c) dosage of adsorbent material and contact time in relation to the removal rate of phosphorus. The best adsorption occurred at pH 4 and other low pH values. High pH conditions affect the surface load of the adsorbent decreasing the adsorption rate. Laterite proved to be effective for the removal of phosphorus in synthetic effluents and can be used in filtering units to remove pollutants. Simplified techniques such as this can be used to meet the demand of the population without access to water treatment and distribution.

Iron concentration in water affects water biota and water quality as a whole. Human activity, landscape characteristics, and soil type are the main factors associated with iron bioavailability. The map above shows altimetry of Dourados and Brilhante rivers where considerable elevation change can be observed from both river headwaters increasing high iron concentration rock weathering. In this intense agriculture activity region native forest conservation practices are critical to revert water contamination with metals and reduce both water biota and human health risks.

These maps show the residence time (RT) isolines in the Mundaú/Manguaba Lagoon Estuary Complex (CELMM), located on the coast of Alagoas state, Brazil. These isolines are associated with wind and freshwater discharge and affect water renewal processes as well as salinity levels and water temperature. As shown in the map, the region near the inlets and in the channel’s residence time was low and less than 10 days. In the back area of the lagoon, the residence time is high with a significant spatial variation. These areas of low circulation are important to identify since they are potentially susceptible to pollutant accumulation.

The Permanent Preservation Area (PPA) Water index is intended to assess the level of degradation of urban water resources. Its unique feature is not to employ water quality monitoring data, usually unavailable in developing countries. In contrast, it employs easy-to-apply innovative territorial information available in existing databases. The example presented in the map shows the result of PPA Water Index applied to the municipality of Fortaleza, CE, Brazil, categorized in five PPA management levels: Unconcerned (red), Inefficient (orange), Regular (yellow), Concerned (light green), and Efficient (dark green) management of PPAs.

These maps show the distribution of heavy rainfall in Brazil based on a 5-year return period. These results were obtained from IDF (intensity-duration-frequency of heavy rain) relationships of gauge stations in the Brazilian territory. The map in the top left shows heavy rainfall with 5-minute duration. The one to the right shows 30-minute duration. The one at the bottom left shows 60-minute duration and the last one to the right 120-minute duration. According to these results, the highest values are concentrated in the Amazon region and in the southern part of the country and the lowest in the semi-arid region in the northeast. These estimates are important for the design of micro-drainage structures preventing them from being damaged by heavy rainfall events.

With the goal of assessing possible impacts of fish farming in great-volume cage systems on the water quality of a reservoir, the authors provided abiotic data from 72 samples obtained before and after farming site implementation. The figure shows the principal components analysis results for seven limnological variables. The highest dissolved oxygen (OD) concentrations were observed before the fish farm became operational. During the post-production period, the highest phosphorous (PT) and ammonium (NH4) concentrations were observed as well as high conductivity and turbidity values. Authors concluded that fish farming in cage systems located in Solteira Island Reservoir, Brazil, caused significant temporal and sudden spatial changes in water physical and chemical variables.

This research is based on the evidence that the extract of Moringa Oleífera Lam has shown excellent performance for water clarification, reaching 90-94% of turbidity removal. In order to verify such potential, this study focused on applying a hybrid treatment system to the removal of reactive dye Blue 5G from aqueous solutions. This figure shows the surface response for the concentration of residual iron. This surface shows that the lowest values for the concentration of residual iron are achieved when a high dose of aqueous extract of Moringa Oleífera Lam is used and low values of electric current intensity are employed.

In a review about the use of isoscapes for natural resource management in the Brazilian context, which has high biological diversity and landscape heterogeneity, the authors present this figure that shows mean annual precipitation δ18O (A) and δ2H (B) isoscapes. As this figure presents, the average rates show a significantly lower spatial variation in comparison to temporal and spatial fluctuation found by other studies at a state level. Therefore, developing precipitation isoscape models specific for Brazil is imperative, since current global models mask part of the natural variations of isotopic ratios.

The figure shows the resulting morphometric characterization of Peixe river watershed derived from different digital elevation models generated from five elevation data sources (three from SRTM 90-meter resolution data and two from 1:100.000 scale topographic maps). Results indicated that SRTM-O, SRTM-TR, and CT-TR provided the incorrect generation of hydrography in the region of the São Franciscana Depression (flat region), observed by the diversion of main river and generation of the mouth in another basin, causing significant errors in the determination of the morphometric characteristics of the basin, mainly in the drainage area and length of the main river. On the other hand, SRTM-TRH and CT-TRH presented excellent performance and are indicated for on-site study.

These maps show the variation of EI30 index that was computed as the product of total kinetic rainfall energy (EC) and maximum 30-min precipitation intensity (I30) in Mato Grosso State, Brazil. During the first and second EI30 periods (October-November and December-March, respectively) many agricultural activities occur in the State. The most critical period is October to February when activities such as tilling, sowing, and harvesting are concentrated. The third period (April-September) is the least critical because the majority of the soils are covered by the crop canopy.
