Green America and China Labor Watch have launched their campaign to protect the health of factory workers assembling the devices in China. The groups unveiled an online petition protesting the use of benzene and n-hexane in the production of iPhones. Benzene is a carcinogen that can cause leukaemia if not handled properly and n-hexane has been linked to nerve damage. Apple says it has already removed a long list of toxic chemicals and ensures all remaining toxic substances comply with U.S. safety standards.
