Concentrations of non methane-VOCs and risk levels of employees' exposure to VOCs were determined at two Finnish waste water treatment plants. The concentration of hydrogen sulphide (H2S) reached the Finnish OEL (occupational exposure limit). The concentrations of styrene, 1,2-dichloroethane, and toluene were found to be elevated at plant A. 328.4 microg/m3 of styrene and 709.8 microg/m3 toluene was found in the sludge dewatering, and 955.8 microg/m3 of 1,2-dichloroethane was detected in the… CONTINUE READING
