摘要

This research analyzed nine casting industries located in western Mexico and their waste streams, including slags, sand, dust and sludge. All of these are considered dangerous by Mexican Legislation due to their concentrations of heavy metals. Analytical results show that lead is the main problem in these wastes. Field sampling showed that these industries do not have any protocol for waste handling and storage.
