In spite of this, no detailed studies list the exact chemical composition of these effluents. The present study reports the results of analyses performed over a 6-month period involving 15 standard water parameters. Over 160 substances including 33 metals, 58 volatile organic compounds (VOCs), 16 polycyclic aromatic hydrocarbons (PAHs), 24 chlorophenols (CPs), 16 alkylphenols (APs), 5 chloroanilines (CAs) and 7 polychlorobiphenyls (PCBs) were monitored. The industrial effluents presented polycontamination involving metals, minerals and organics with a high degree of qualitative and quantitative variability. Of the 160 substances monitored, 46 were regularly found: 25 inorganics including 8 metals (Co, Cr, Cu, Fe, Ni, Pb, Sn, Zn) and 21 organics (4 PAHs, 10 VOCs, 4 CPs and 3 APs). Eighteen were systematically presented at quantifiable levels.展开更多
