Examination of organic and inorganic xenobiotics in equipped printed circuits

摘要

To develop a proper recycling and waste disposal strategy for equipped printed circuit boards a good know- ledge of the hazardous residues residues is required. Following substance groups were selected for investigation: PCB_z, PBBz, PCPh, PBPh, PCB, PBB, PBDPE, PAH and TBBP-A. After sampling in a electronics Recycling and disposal company the printed circuits were disassembled and the components ere sorted into 34 fractions ad gravimetrically registered. The amounts of the organic and inorganic xenobiotics of 22 fractions was determined individually.
