As public health professionals, we are concerned about the high rates of birth defects in Alaska and possible links to environmental contaminants. As reported last month in the Daily News, the fact that "Alaska infants are twice as likely to be born with major birth defects as infants in the U.S. as a whole" cannot be explained simply by cigarette smoking, alcohol consumption, maternal age and diet. The article did not discuss the growing body of scientific evidence that suggests environmental contaminants are linked to birth defects and other harmful reproductive health effects in both males and females.

Even though many people think of Alaska as pristine, Alaska has over 2,000 toxic waste sites. They include over 700 formerly used military defense sites, countless open dump sites throughout rural Alaska, and five major military sites that are designated among the most hazardous sites in the country (known as Superfund sites) -- two of which are in Anchorage. These sites contain hazardous materials that are linked to a range of adverse health effects, including birth defects.

Alaska and the circumpolar Arctic are also subject to pesticides and industrial chemicals that originate from thousands of miles away, traveling northward via oceanic and atmospheric currents and eventually settling in cold climates. These chemicals accrue in the north because the cold climate and fat-based food web favor retention of these persistent toxics.

Even toxic chemicals that have been banned in the U.S. (such as the insecticide DDT and class of industrial chemicals known as PCBs) continue to accumulate in the Arctic and sub-Arctic. Contaminants threaten the health of northern peoples who rely on traditional diets of fish and marine mammals.
