Contaminants, diet, plasma fatty acids and smoking in Greenland 1999-2005.

摘要: Abstract Objectives The purpose of this study is to monitor and assess human exposure pollution in the Arctic which presents a potential future health risk for local populations. Epidemiological studies Greenland have shown that blood levels several organic contaminants are very high, especially North where people depend on food. In East (Ittoqqortoormiit (Scoresbysund)) population shows highest persistent pollutants found countries, PCB, exceed Canadian guideline levels. As other predominant source these diet. However, factors such as smoking may influence metabolism thereby accumulation toxic substances. Study design This project part program ongoing circumpolar “Artic Monitoring Assessment Programme”. Lifestyle, anthropometric factors, dietary survey results covering 500 men women from 6 Greenlandic districts were analyzed along with lipids, fatty acid profiles, heavy metals concentrations (POPs). Results showed traditional food average provided 20–30% total energy intake. relative monthly meal intake seal, whale, polar bear, fish game, composition imported food, varied between districts. Seal bear intake, and, particular all plasma n-3 acids, significantly correlated contaminant concentrations, (betaHCH, chlordanes, DDTs, Hexachlorobenzene, Mirex, PCBs, toxaphenes) p ⁎⁎ . After adjusting age, district, or was high above mentioned POPs. Conclusion main predictors male gender, n-3/n-6 ratio marker marine mammals.
