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.
