The world’s ten most polluted places of 2013

Independent environmental organization Green Cross Switzerland in cooperation with the US-based Blacksmith Institute, presents a list of the world’s ten most polluted places. These ten sites are spread over eight countries.


The top-ten list appears in alphabetical order by country. Given the variety in size, population and type of pollution, a ranking would be neither realistic nor feasible.

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.
