MICROSUBSTANCES IN URBAN STORM WATER

During 1976 a catchment in Goeteborg was investigated with respect to microsubstances in storm water and atmospheric fallout. The microsubstances studied were 17 heavy metals and PCB, DDT with derivatives, HCB and Pah. The concentrations of heavy metals in storm water were not remarkably high compared with the concentrations in waste water and sometimes in drinking water. For AS, CD, HG, SB, V and PB atmospheric fallout could explain a great deal of the metal content in the storm water. For the other metals only a smaller fraction could be explained by atmospheric fallout. Most of the heavy metals originate from traffic and from corrosion. The concentrations of pcb, DDT, and HCB were relatively low compared to results of earlier investigation of dustfall. The concentration of PAH in the storm water was high (10-320 g of naftalene- equivalents/1. Unfiltered sample), on one occasion even higher than in waste water. Most of the pah was found to be attached to particles. Applications of the different microsubstances and their effects on man, flora, and aquatic fauna are given. /TRRL/
