Women of childbearing age from around the world have been found to have high levels of mercury, a potent neurotoxin which can seriously harm unborn children.

The new study, the largest to date, covered 25 of the countries with the highest risk and found excessive levels of the toxic metal in women from Alaska to Chile and Indonesia to Kenya. Women in the Pacific islands were the most pervasively contaminated. This results from their reliance on eating fish, which concentrate the mercury pollution found across the world’s oceans and much of which originates from coal burning.

The most extreme levels were found in women from sites in Indonesia where mercury is heavily used in small-scale gold mining and where fish is also commonly eaten. Such gold mining leads to serious mercury pollution and is also a source of harm to women in Kenya, Paraguay and Myanmar.

Industrial pollution is another source of mercury, and the research found this affected women in Nepal, Nigeria and Ukraine.

“Millions of women and children in communities mining gold with mercury are condemned to a future where mercury impairs the health of adults and damages the developing brains of their offspring,” said Yuyun Ismawati, an Indonesian woman from Ipen, the coalition of NGOs that produced the scientific report. “As long as the mercury trade continues, so too will the mercury tragedy.”

Cook Islands resident Imogen Ingram, from the Island Sustainability Alliance, learned that her own mercury levels were two-and-half times higher than the US Environmental Protection Agency’s safety threshold. “It is really alarming to learn that you have, without knowing, passed on mercury to your child,” she said. “Mercury contamination across the Pacific Islands is high because we eat fish. But I do not want to be told not to eat fish. Coal-fired power, one of the primary sources of mercury pollution in the oceans, is the real offender. It is time to phase it out.”

The Ipen work expanded a smaller study it conducted with the UN Environment Programme to test hair samples from more than 1,000 women from 36 places in 25 countries. In the Pacific Islands, which are far from all industrial sources of mercury pollution, 86% of the women had levels above the 1ppm safety limit, with most over three times that.

Above 1ppm of mercury, brain, heart and kidney damage can occur. The most recent scientific assessment indicates that lifelong brain damage to foetuses can begin at the lower level of 0.58ppm and in many of the sites studied virtually all the women exceeded this level.
