The Riachuelo/Matanza River is one of the most polluted areas in the world. It runs straight through the capital city of Buenos Aires but comes with a host of problems that are affecting people living in proximity to the river. Around 90,000 tons of heavy metals are dumped into the river every single year.
Unfortunately, a lot of this pollution comes from the discharge of more than 15,000 local enterprises, mainly chromium and sulfides. Unfortunately, a lot of the air pollution in Argentina comes from the piling of landfills, which emit toxic fumes into the air (DW).
