Brazil uses forensic science to trace gold’s origin and tackle illegal mining in the Amazon

By Gabriela Sá Pessoa BRASILIA, Brazil (AP) — Brazil is using forensic science to tackle illegal gold mining in the Amazon, a top threat to the rainforest, Indigenous groups and other communities there that has accelerated deforestation and driven mercury contamination to dangerous levels. The work takes place at the National Institute of Criminalistics in Brasilia, the country’s capital, where federal police have set up a “gold lab” that collects and analyses samples from across the country.
