food and estimated daily dioxin toxic equivalent intake.
This is an expense she is willing to pay--they will receive at least three years' light from Little Sun, and the family are free from breathing hazardous kerosene fumes (breathing fumes from a kerosene lamp is the toxic equivalent to smoking 40 cigarettes a day).
Table 1 - international toxic equivalent factors (I-TEF) for the congeners of the chlorinated dioxins and furans Dioxin congener I-TEF Furan congener I-TEF 2,3,7,8-tetra CDD 1 2,3,7,8-tetra CDF 0.
4 grams Toxic Equivalent Quotient ("TEQ") of dioxins and furans.
He added that late in 1994 the Environmental Protection Agency proposed regulations that would provide for the measurement of the dioxin family to be expressed as toxic equivalent quotients.
The unique congener pattern [TCDD was the major (70-80%) contributor to the toxic equivalent (TEQ) (38,39)] suggested that the community was exposed to a TCDD-contaminated stock of the herbicide 2,4,5-trichlorophenoxyacetic acid (2,4,5-T), similar to the defoliant Agent Orange that was used in Vietnam.
Blood dioxin levels for the TrCP workers were originally obtained from a small sampling in 1992 which indicated a higher overall toxic equivalent (TEQ) exposure along with the presence of the toxic PnCDD congener.
Furthermore, the final result is only a toxic equivalent and thus gives no information about the dioxin pattern of exposure, which yields information about the exposure scenario, including the source.
They based those values on how long a man had worked (and where in the plant) and, if available, on recorded body concentrations of TCDD-the most potent dioxin-or its toxic equivalents.
Emissions from hospital and hazardous waste facilities are estimated as totaling about 4300 grams per year in toxic equivalents.
Apparent elimination rates calculated using these two approaches were derived for each individual for each dioxin congener and for summed dioxin toxic equivalents [TEQ; WHO (World Health Organization) toxic equivalency factors (van den Berg et al.
