Lipid Peroxidation and Oxidative Status Compared in Workers at a Bottom Ash RecoveryPlant and Fly Ash Treatment Plants: Hung-Shin LIU, et al. Department of Occupational Safety and Health, Chung Shan Medical University, TaiwanFly ash and ambient emissions of municipal solid waste incinerators contain polychlorinated dibenzo-p-dioxins and dibenzofurans (PCDD/Fs), polycyclic aromatic hydrocarbons (PAHs), other organic compounds, metals, and gases. Hazardous substances such as PCDD/Fs, mercury vapors and other silicates, and the components of bottom ash and fly ash elevate the oxidative damage. We compared oxidative damage in workers exposed to hazardous substances at a bottom ash recovery plant and 3 fly ash treatment plants in Taiwan by measuring their levels of plasma m a l o n d i a l d e h y d e ( M D A ) a n d u r i n e 8 -hydroxydeoxyguanosine (8-OH-dG). Significantly higher MDA levels were found in fly ash treatment plant workers (3.20 µM) than in bottom ash plant workers (0.58 µM). There was a significant association between MDA levels in workers and their working environment, especially in the fly ash treatment plants. Levels of 8-OH-dG varied more widely in bottom ash workers than in fly ash workers. The association between occupational exposure and 8-OH-dG levels may be affected by the life style of the workers. Because more dioxins and metals may leach from fly ash than from bottom ash, fly ash treatment plant workers should, as much as possible, avoid exposing themselves to fly ash.

“…The potential environmental impact and health risks of environmental pollutants, especially PCDDs and PCDFs generated by hazardous waste incinerators (HWIs; Agramunt et al 2003) and municipal solid waste incinerators (MSWIs; Kumagai et al 2003;Takata 2003), are subjects of controversy and concern (Schuhmacher et al 2002).…”

The objective of this study was to evaluate the congeners of polychlorinated dibenzo-p-dioxins (PCDDs) and polychlorinated dibenzofurans (PCDFs) in Korean serum samples as biological markers. Serum samples from 103 participants were analyzed. Participants consisted of 28 workers in municipal solid waste incinerators (MSWIs), and 21 men and 54 women who had lived for at least 3 years prior to 2002 in areas within 300 m of incinerators in large Korean cities. Serum samples were analyzed for 17 PCDD/PCDFs congeners by high resolution gas chromatography-high resolution mass spectrometry. Geometric mean (GM) PCDD/PCDF levels in the serum samples were 3.14, 8.04, 6.12 and 6.60 pg TEQ/g lipid for workers, male residents, female residents and the sum of male and female residents, respectively. The GM PCDD/PCDF level in the serum of workers was not significantly different from the values for residents near MSWIs. In the 75 participants who resided near MSWIs, the congeners that most contributed to the total TEQ were 1,2,3,6,7,8-hexachlorodibenzofuran (1,6-HxCDF), 2,3,4,7,8-pentachlorodibenzofuran (4-PeCDF), 1,2,3,4,6,7,8-heptachlorodibenzofuran (1,4,6-HpCDF), 1,2,3,7,8,9-hexachlorodibenzofuran (1,9-HxCDF), 1,2,3,4,7,8-hexachlorodibenzo-p-dioxin (1,4-HxCDD), 1,2,3,6,7,8-hexachlorodibenzo-p-dioxin (1,6-HxCDD). In the workers, the congeners that made the greatest contribution were 1,6-HxCDD, 4-PeCDF, 1,2,3,4,6,7,8-heptachlorodibenzop-dioxin (HpCDD), and 1,6-HxCDF. In conclusion, the serum TEQ levels for PCDD/PCDFs in the incinerator workers and residents near the MSWIs in Korea were lower than those reported for other countries. Comparison of the PCDD/PCDF levels of workers at MSWIs and nearby residents revealed no significant enhancement of PCDD/PCDF exposure in workers. PCDD/PCDF intake from animal origin was assumed to be lower than that of Europeans. Further studies of Korean foods are needed to clarify the exposure route for PCDD/PCDFs in the Korean population.

“…They are generally thought of as an industrial problem because they are formed as the by-products of chlorine-containing manufacturing processes or from incineration (Everert and Baeyens, 2002;Birnbaum et al, 2003;Hays and Aylward, 2003). Therefore, incineration workers have usually been chosen to evaluate the toxic effects of dioxin in humans (Kumagai et al, 2003). However the incineration workers generally are exposed to another toxic component, PAHs which are a class of stable organic molecules made up of carbon and hydrogen.…”
