Ten most polluted places in the world

The US-based Blacksmith Institute, an independent environmental organisation, in cooperation with Green Cross Switzerland presents a list of the ten most polluted places in the world in 2007.


The criteria for the list were compiled by an international group of experts, including scientists from Johns Hopkins University, Hunter College, Harvard University, IIT Delhi, University of Idaho and Mt. Sinai Hospital. The panel also includes leading representatives of international environmental companies as well as the Blacksmith Institute’s own Technical Advisory Board and specialists from Green Cross Switzerland. The methodology this year was refined to attach more importance to the scale and toxicity of the pollution as well as the number of endangered people. The Blacksmith Institute and Green Cross Switzerland have been partners since 2006. The two organisations jointly work on a project to eliminate pollution from former mining and smelting operations in Rudnaya Pristan in Russia’s far east. This place was listed in the 2006 top ten.

Environmental Reports


Since 2007, the yearly environmental toxin reports published by Green Cross Switzerland and the Blacksmith Institute have been instrumental in increasing public understanding of the health impacts of toxic pollutants and their sources.


The Environmental Toxin Report 2012 describes known environmental toxins and points to their industrial applications and most frequent health effects. In addition, the Report identifies the ten most important sources of environmental toxins and quantifies, for the first time, the global scale of health damage due to toxic substances. It also shows that the health impacts of industrial pollutants measured are roughly equal to those of the three major global infectious diseases AIDS, tuberculosis and malaria.


The Environmental Toxin Report 2011 is based on the estimated number of people affected by the sources of pollution, as well as the number of locations, identified worldwide, where environmental toxins occur in concentrations that are detrimental to health. Reports on the ten most dangerous sources of environmental toxins and the worst pollution problems were issued in the years 2008 and 2010. The environmental report published in 2009 contains case studies concerning successful remediation projects.
