The aim of this study was to examine the water quality of the Extrema River spring in a Brazilian Cerrado area. Three collection sites (P1 - P3) were sampled in the dry and rainy seasons, which are close to industries from different sectors. In the physicochemical analysis, a decrease in dissolved oxygen levels (<5 mg/L) and pH (< 6) at P3 was detected.

Article Synopsis
  • Disturbance in stream surroundings affects water quality and harms aquatic life, prompting a study on the impact of land use on fish biomarkers in Brazilian savanna streams.
  • The study focused on the Neotropical tetra fish, Astyanax lacustris, with fish exposed in cages across 13 streams during both dry and wet seasons, analyzing blood, liver, and gills for various biomarkers.
  • Findings revealed that increased anthropogenic disturbance correlated with genetic damage and reduced liver enzyme activity while also indicating negative impacts on water quality, suggesting that multibiomarker strategies can effectively assess the effects of landscape changes.

The increasing use of pesticides has caused global concerns about the toxic effects and adverse consequences of pesticides on humans and the environment. Among the ways to understand the impact of pesticides, the Allium cepa bioassay stands out. This test is suitable to evaluate different toxic, cytotoxic, genotoxic, and mutagenic outcomes.

Uncontrolled urbanization growth contributes to the pollution of aquatic environments. Heavy metals released by domestic and industrial effluents can negatively affect aquatic organisms. This study aimed to evaluate the effect of environmental pollutants, such as metals, on fish DNA damage, in stretches of an urban stream.
