Webcomplication in toxicity assessment is that noncancer toxicity can result from relatively low dose levels. For example, all doses of Aroclor 1016 predicting a cancer risk above 5E-6 are also associated with an unacceptable noncancer hazard. Another consideration for toxicity assessment is the dioxin-like activity of co-planer PCBs. WebThe risk of DL-PCB toxicity via inhalation in the Agbogbloshie area was 4.2 pg TEQ/day, within similar order of magnitude of an estimated risk of 3.85 pg TEQ/day faced by e-waste workers working averagely for 8 h per day.
