Goodbye, mad hatter: UBC expert promotes safer gold mining

Small-scale or artisanal mining is responsible for producing around 400 tonnes of gold a year worldwide. It supports 160 million people, including about 16 million who are directly involved in mining. But because most small-scale miners rely on mercury to extract gold (big mining companies no longer use mercury), the waste runoffs from the mines end up polluting the air and nearby waterways.
