From IT World Canada:
Something’s cooking in a forgotten corner of the province of Zheijiang, China — and it’s the perfect recipe for a health and environmental disaster. Ingredients of this toxic swill include assorted electronic circuit boards simmered in pure nitric and hydrochloric acids.
For a meagre $1.50 a day, labourers in the province’s Taizhou region heat computer circuit boards in order to extract and recover valuable metals within the products for reuse. The process is done outdoors, by hand, and releases lethal toxic fumes.
