The results suggested that potential health risk might be occurred in those ambient air.

📌 3 Key Takeaways

🎯
Objective & Hypothesis:The objective of this study was to assess the potential health risks of polychlorinated dibenzo-p-dioxinsand dibenzofurans (PCDD/Fs) in ambient air of different factories.
📊
Key Findings & Data:We found that toxic equivalent concentrationof PCDD/Fs (TEQ) ranged from 0.236 ± 0.198 to 0.48 ± 0.442 pg I-TEQ/Nm3 in 11 kinds of factories, andaverage value of TEQs in 11 factories were lower than atmospheric PCDD/F standard (0.6 pg I-TEQ/m3)announced in Japan, and the mean values of TEQ in ambient air of factories were in the decreasing orderof MWI > MSWI > PILI > MF > OC > SST > HSWI > OMC > PM > EF > IC.
💡
Conclusion & Impact:The results suggested that potential health risk might be occurred in those ambient air.

Özet

The objective of this study was to assess the potential health risks of polychlorinated dibenzo-p-dioxinsand dibenzofurans (PCDD/Fs) in ambient air of different factories. In this study, fifty-five locations wereselected and represented eleven type factories, including municipal solid waste incineration factory(MSWI), hazardous solid waste incineration factory (HSWI), sewage sludge treatment factory (SST),medical waste incineration factory (MWI), electronic factory (EF), pharmaceutical factory in large infusion (PILI), oral medication class factory (OMC), inorganic chemical factory (IC), organic chemical factory(OC), paper mills factory (PM) and mechanical factory (MF). We found that toxic equivalent concentrationof PCDD/Fs (TEQ) ranged from 0.236 ± 0.198 to 0.48 ± 0.442 pg I-TEQ/Nm3 in 11 kinds of factories, andaverage value of TEQs in 11 factories were lower than atmospheric PCDD/F standard (0.6 pg I-TEQ/m3)announced in Japan, and the mean values of TEQ in ambient air of factories were in the decreasing orderof MWI > MSWI > PILI > MF > OC > SST > HSWI > OMC > PM > EF > IC. In addition, lifetime average dailydoses (LADDs) and their resultant excess cancer risks (ECRs) for workers in those factories were calculated. The results suggested that potential health risk might be occurred in those ambient air.
