The steps of gold washing and burning boards, which cause fatal damage to the environment, are also the two steps through which Guiyu people earn substantial profits.
Gold washing refers to using concentrated acids to extract gold from circuit boards, while burning boards involves throwing plastic boards into a charcoal furnace for burning to obtain the copper inside.
Both operations produce a large amount of thick smoke, containing dioxin, lead, and other highly toxic carcinogens.
The workshops for gold washing are almost impenetrable, filled with rolling smoke. Sisi felt suffocated and uncomfortable after just a minute inside, experiencing headaches and nausea.
Sisi and her two companions disguised themselves as tourists. Perhaps because they were fashionably dressed and young, the locals did not show much hostility towards them and were willing to answer some questions.
