Smoke from burning electronic waste at Agbogbloshie in Accra is filling the air with toxic chemicals, and researchers have long said the harmful effects are already getting into people's bodies — making them sick and, in some cases, killing them. It has been nearly two decades since clear evidence of direct human exposure to e-waste contaminants was found among workers at Agbogbloshie. In a 2012 study, urine samples from 20 male e-waste workers aged between 15 and 42 found significantly higher levels of iron, the flame-retardant antimony, and lead in the urine of the e-waste workers.
