NUUK, Greenland - Twice as many girls as boys are being born in remote communities north of the Arctic Circle. Across much of the northern hemisphere, particularly in the US and Japan, the gender ratio has skewed towards girls for the first time.

Now scientists working with Inuit villages in Arctic Russia and Greenland have found the first direct evidence that this trend is linked to widespread chemical pollutants. Despite the Arctic’s pristine environment, the area functions as a pollution sink for much of the industrialised world. Winds and rivers deliver a toxic tide from the northern hemisphere into the polar food chain.

Scientists have traced flame-retardant chemicals used in everything from industrial products to furniture, phones and laptops to the food chain, finding high levels of these pollutants in seabirds, seals and polar bears. The Inuit have traditionally relied on a hunter- gatherer’s diet almost exclusively made up of marine animals, making them especially vulnerable to toxic pollutants.

Historically in large populations, it is considered normal for the number of baby boys slightly to outnumber girls in a trend believed to compensate naturally for greater male mortality rates.

The researchers suspect-ed that this linked widespread exposure among pregnant women to hormone-mimicking pollutants. But Danish scientists examined 480 families in the Russian Arctic and found high levels of the hormone-mimicking pollutants in the blood of pregnant women, and twice as many girls being born as boys.
