The Finnish study found that children with the worst teeth were born to mothers with the highest levels of dioxin in their breast milk, thus establishing a dose-response relationship. The researchers examined PCBs separately from the other dioxins and dioxin-like compounds and they found that the PCBs did not contribute to the children's tooth problems. People living near any of the 110 Superfund sites where dioxins have been identified. Sport fishers in the Great Lakes regions are very likely to have high exposure to dioxin, with Lake Huron the highest, Lake Michigan next highest, and Lake Erie the lowest. Currently 66 fish advisories have been issued by 21 states because of dioxin-contaminated fish.
Many indigenous people eat far more fish than the average.
Under these circumstances, even low levels of dioxin contamination in fish can add up to a hazard. People eating food grown on soil treated with sewage sludge may be in danger.
