Environmental destruction answer given by professional and technical personnel: BCR3 state by continuous extraction method and Tessier5 step sequential extraction method for certain heavy metals in the waste board chemical speciation studies. The results show that, BCR sequential extraction of heavy metals in the circuit board for waste extraction rate higher than the Tessier sequential extraction method. Discarded circuit boards Cu, Pb, Zn and Ni various forms of distribution vary widely. BCR and Tessier sequential extraction method results show that PCB waste in the presence of Ni mainly of residue, a small risk of contamination of the environment; while Pb and Zn mainly in acid extractable or exchangeable state and the presence of carbonates in Southern acid rain environments easily eluted; BCR sequential extraction method and activity evaluation Tessier of gold-plated Cu Dongguan inconsistent recovery, but due to the high amount of waste in the Cu wiring board, the impact on the environment can not be ignored.
