Dioxin-like PCBs in the environment - human exposure and the significance of sources

Dioxin-like compounds in agricultural soils near e-waste recycling sites from Taizhou area, China: Chemical and bioanalytical characterization

“…PCBs with dioxin-like structure represents potent AhR agonists (Alcock et al, 1998). As shown in Table 1, the concentrations of PCBs did not vary significantly among sampling locations.…”

Atmospheric polychlorinated biphenyls in Indian cities: Levels, emission sources and toxicity equivalents

“…TEQ input of coplanar PCBs was mainly contributed by PCB congeners CB-77, -105, -118, -156, and to a lesser extent CB-126 (Alcock et al, 1998). PCB-126 in the above samples from these three cities could be a summated influence of the domestic burning of coal and wood (Lohmann et al, 2000) for residential cooking and heating and combustion of the solid waste (Oliver and Niimi, 1988;Lohmann et al, 2000).…”

Variables Affecting Emissions of PCDD/Fs from Uncontrolled Combustion of Household Waste in Barrels

“…Total PCBs were approximately a factor of 200 greater than total PCDD/Fs; however, TEQ PCB is approximately 5% of TEQ DF , which is an observation that is consistent with data from MWCs. 16 This suggests that, in burn barrels, the PCBs that are formed are predominantly the nonplanar (ortho-substituted) PCBs that do not exhibit dioxin-like activity in biological systems.…”
