In the last year the Blacksmith Institute and Green Cross Switzerland have been using field studies and expertise in pollution analysis to prepare estimates on the contribution of industrial toxic pollutants to the burden of disease. The estimates in this report are based on information collected through the Blacksmith Institutes Toxic Sites Identification Program (TSIP). This program is an ongoing process to identify and screen contaminated sites in low and middle-income countries. The goal of TSIP is to identify point-source pollution coming from contaminated sites that present a risk to public health. The TSIP database includes information on the concentration.
