Environmentalgraffiti.com have published what they think is the top 5 deadliest cities in the world.
2. Dzerzhinsk, Russia
Until recently, the city of Dzerzhinsk in Russia used to produce huge quantities of chemical weapons, including mustard gas and lewisite. Chemical weapons ceased to be produced by 1945. However, the waste was buried underground, contaminating water and crops. The site however, remains the largest producer of chemicals for the Russian Federation. Life expectancy is low at 42 for men and 47 years for women. This is attributed to the high levels of persistent organic chemicals.
