Dioxin-like PCBs released from waste incineration and their deposition flux.

摘要: To investigate the formation and decomposition behaviors of dioxin-like PCBs during incineration municipal solid wastes in a recently constructed facility, concentrations were measured waste before incinerator emission gas residues. Using these values, release/inflow ratios PCB congeners (ratio amount released from to flowing into through waste) calculated. For 126, 169, 189, greater than 1. In contrast, other much less take account atmospheric sources, amounts via emissions compared with depositions Kyoto City area. Most PCDD/F homologue groups deposited similar those found incinerator. Deposition 81, 189 also emissions. However, 105, 114, 118 greatly exceeded reviewing congener profiles industrial products gas, following general trends observed: (i) whose contents are high (e.g., 105 118), higher gas. (ii) percentages 126 189),
