(00474)Trace metals in soils and water in the area of a small - medium waste electrical and electronic equipment recycling plant

摘要

A research conducted in order to investigate the environmental impact of an e-waste recycling plant to the soil and water resources of the surrounding area. Therefore trace elements in both water and soil samples were determined with Inductively Coupled Plasma - Mass Spectrometry (ICP-MS). Heavy metals in water comply with drinking water criteria, except Pb. Pb, Concentrations of Pb, Cr, Ni, Cu, Mn, Zn were higher in the rainwater collection tank (43.50, 10.90, 18.87, 81.17, 177.99, 330.17 μg/L)than the surficial water inside (8.93, 1.27, 4.97, 17.0, 91.87, 72.97 μg/L)and outside the plant (4.18, 1.28, 1.60, 10.35, 26.21, 12.10 μg/L). Ecological risk of soil samples was assessed with Enrichment Factors. Enrichment factor, for soils showed low to moderate enrichment. The more enriched soil samples in Cu, Pb, Zn, Cd and Hg were two collected west of the company S19 and S20 and two samples collected east S9 and S10.
