Abstract
This article characterizes the main heavy metals of environmental concern, describing sources of contamination and health effects, including historical cases such as Minamata disease. The research compares heavy-metal concentrations in compost made from source-separated versus non-separated waste in municipalities of Antioquia, supporting source separation as a quality criterion for organic amendments.
