For the first time since 2007, the Blacksmith Institute based in New York and Green Cross Switzerland are pointing fingers on not just what, but where in the world the toxic threats are the worst.
In previous years, the two institutes have identified the top toxic threats and clean-up successes as seen on a global scale. Last year's number one threat for example was lead exposure from lead-acid rechargeable car battery recycling sites.
"In this year's report, we cite some of the most polluted places we've encountered. But it is important to point out that the problem is really much larger than these ten sites," says Richard Fuller, president of Blacksmith Institute in a press release. "We estimate that the health of more than 200 million people is at risk from pollution in the developing world."
Some of the sites listed in the 2007 report are still so devastating to human health as to be included again in 2013, those sites are marked here with an * at the top of this list. Others, such as two sites in China, have made enough improvements to be removed from this list and replaced with other areas such as Agbobloshie, an e-waste processing site in Accra, Ghana, and Kalimantan, Indonesia, which has become contaminated with mercury resulting from small-scale gold mining. The list, presented here is not ranked.
