Over the past decade, this series has identified and drawn attention to the worst, and most dangerously polluted places on the planet, while documenting and quantifying the startling health and environmental impacts of this neglected problem. The “World’s Worst” series of reports aim to raise global awareness about the extent and impacts of toxic pollution in low- and middle-income countries while also highlighting cost-effective solutions. This year’s report, The World’s Worst Pollution Problems 2016: The Toxics Beneath Our Feet presents an update of the top ten polluting industries based on each source’s global burden of disease. The top ten industries are identified as used lead acid battery (ULAB) recycling, mining and ore processing, tanneries, dumpsites, industrial estates, smelting, artisanal small-scale gold mining (ASGM), product manufacturing, chemical manufacturing, and the dye industry. These industries collectively put over 32 million people at risk and account for 7 million to 17 million Disability-Adjusted Life Years (DALYs) in low- and middle-income countries. Each industry sector is described in detail with its respective pollutants outlined. Worst Polluting Industries Ranked by DALYS RANK INDUSTRIES DALY 1 ULAB 2,000,000–4,800,000 2 Mining and Ore Processing 450,000–2,600,000 3 Lead Smelting 1,000,000–2,500,000 4 Tanneries 1,200,000–2,000,000 5 ASGM 600,000–1,600,000 6 Industrial Dumpsites 370,000–1,200,000 7 Industrial Estates 370,000–1,200,000 8 Chemical Manufacturing 300,000–750,000 9 Product Manufacturing 400,000–700,000 10 Dye Industry 220,000–430,000 (Left) A woman tends fires of burning coal at a village outside Djaria, India, the epicenter of the country’s largest coal deposits. Villagers scavenge coal from the bottom of nearby open pit mines, burn the coal pieces to form charcoal, then sell bags of the processed coal in local markets. Photo by Larry C.

As the extent and number of the worst sites became better understood, it became important to generate contaminated sites globally and refined our burden figures for the health impacts of these sources. of disease calculations.

The report evaluates the Pure Earth and Green Cross Switzerland have leading pollution-causing industries globally and investigated and analyzed hundreds of additional associated contaminants that can be harmful to The Toxics Beneath Our Feet 6 both human health and the environment. MAIN FINDINGS FROM 2012 REPORT Data for the report is largely the result of toxic site identification efforts by Pure Earth, formerly The 2012 report extrapolated from Blacksmith Institute, and Green Cross Switzerland.

Scale of the Problem The top ten list of industrial sources were identified as: battery recycling, lead The number of toxic sites identified and recorded smelting, mining and ore processing by Pure Earth, Green Cross and local collaborators tannery operations, industrial/municipal has continued to increase and an extrapolation from this suggests that there are perhaps 150,000 dumpsites, industrial estates, artisanal gold sites in the approximately 50 countries where mining, product manufacturing, chemical investigations are underway.
