Blacksmith Institute and Green Cross Switzerland have published the 2012 The World’s Worst Pollution Problems report attempting to quantify how human health was impacted by specific industries and toxic pollutants created. This evaluation is based on data collected on toxic hotspots around the world. Below table shows the 10 worst industrial pollutions on 2012.
DALY means "disability-adjusted life year". It measures the overall disease burden, expressed as the number of years lost due to ill-health, disability or early death. One DALY, therefore, is equal to one year of healthy life lost.
The study also indicates that the impact on health in low and middle income countries from these sites, identified as blue dots on the map below, is very significant and likely higher than in the developed world.
