A goldsmith in Gusau, capital of Zamfara State, Nigeria, is burning sulphuric acid and gold, in order to remove last impurities. The lead contamination in artisanal gold extraction is caused by ingestion and breathing of lead particles released in the steps to isolate the gold from other metals. This type of lead is soluble in stomach acid and children under-5 are most affected, as they tend to ingest more through their hands by touching the ground, and are developing symptoms often leading to death or serious disabilities.
