The increasingly sophisticated PCB boards bring about a lot of wastewater full of chemical substances.If I remember correctly, in some countries, PCB production is also banned,even including PCB-containing products.Though I know PCB will bring much pollution,I am still willing to learn about more details.Thanks!
