Chemical contamination is a significant environmental and public health concern in both Brazil and the USA. In Brazil, industrial contamination of rivers (particularly in the Amazon and in industrial regions like São Paulo) is a major environmental justice issue. In the USA, Superfund sites and the Flint water crisis have brought chemical contamination into mainstream public discourse. The term is used extensively in regulatory, scientific, and media contexts in both countries.
