||Exposure evaluation of dioxins in municipal waste incinerator workers
||July 2003, Vol.41, No.3, p.167-174. Illus. 29 ref.
||In Japan, the largest source of dioxin is solid waste incineration plants. Workers employed at these plants handle fly ash and slag contaminated by dioxins and can absorb dioxins into the body during work, with possible adverse health effects. This study examines dioxin exposures, daily dioxin intake and blood dioxin level in workers employed at municipal incineration plants. Estimated dioxin exposures were 0.5 to 7.2pg TEQ/m3 (TEQ=toxicity equivalents) in daily operations and 0.2 to 92,000pg TEQ/m3 in periodic maintenance. It was also found that the daily dioxin intake can exceed the tolerable daily intake limit values in incineration plants with fly ash of high dioxin concentration. The mean blood dioxin concentration was 346pg TEQ/g lipid in the highest exposed worker group of the Toyono-gun incineration plant and 11 to 40pg TEQ/g lipid in the other incineration plants.
