Article Synopsis
- This study examined the chronic effects of various concentrations of iron (Fe) and aluminum (Al) on zebrafish, looking at potential changes in behavior, health, and genetics.
- Significant locomotion changes and histopathological alterations, especially related to aluminum exposure, were noted even after recovery periods, indicating lasting impacts on the fish.
- The findings stress the need for updated environmental guidelines and monitoring, as low levels of pollutants can still cause harm to aquatic life and affect future generations.
Potential use of distinct biomarkers (trace metals, micronuclei, and nuclear abnormalities) in a heterogeneous sample of birds in southern Brazil.

The analysis of metal concentrations in bird feathers and genotoxicity tests are tools used to evaluate anthropogenic impacts on ecosystems. We investigated the response of birds, used as bioindicators, to disturbances observed in three areas with distinctive environmental characteristics (natural, agricultural, and urban) in southern Brazil. For this purpose, we quantified metals (Mn, Cu, Cr, and Zn) in feathers and determined the number of micronuclei (MN) and other nuclear abnormalities (NA) in 108 birds from 25 species and 17 families captured in the study area.
