Toxic Metals Detected in Bananas After Brazil Mining Disaster

Researchers from Brazil and Spain have investigated the presence of toxic metals in bananas grown near the Doce River estuary, an area contaminated by the 2015 mining disaster in Minas Gerais. Focused on crops like bananas, cassava, and cocoa, the study found levels of metals like lead and cadmium that pose health risks, particularly to young children. While adults face lower immediate danger, long-term exposure could lead to cumulative health effects. The study is part of Amanda Duim's doctoral research at the University of São Paulo, supported by FAPESP. Duim's research aims to understand how these metals transfer from contaminated soil into plants and enter the human food supply.
