These activities increase the risk of contamination by runoff and leaching of pesticides and heavy metals. This study presents the concentration and bioaccumulation of heavy metals copper (Cu) and total chromium (Cr) in matrinxã (Brycon falcatus), a species of fish highly consumed in the region. Liver and muscle tissue was analyzed from 41 samples of B. falcatus collected during the dry season in 2013 from the Teles Pires River basin.
