Most humans have detectable body burdens of polychlorinated biphenyls (PCBs), hexachlorobenzene (HCB), and p,p´-dichlorophenyldichloroethylene (p,p´-DDE), a metabolite of p,p´-dichlorodiphenyltrichloroethane (DDT). Native American communities may be at increased risk of exposure through subsistence-based diets and greater physical contact with contaminated soil and water. In this article we describe the levels of toxicants (PCBs, p,p´-DDE, HCB, mirex, lead, and mercury) among youth 10-17 years old (n = 271) of the Akwesasne Mohawk Nation. Ultratrace, congener-specific PCB analysis of human serum quantitated 83 PCB congeners (plus 18 as pairs/triplets), in addition to p,p´-DDE, HCB, and mirex, and included all major Aroclor-derived congeners typically present in human samples. Twenty congeners (

The new method of nCPAP with Infant Flow was adopted as standard practice in Poland. We monitored its safety and effectiveness over a 2-yr period and found it to be safe and effective as implemented. Additional research is still needed to determine the optimum patient population, strategy for use, and devices.
