Here you will find an essay titled "Chemical Contaminants and Human Disease: A Summary of Evidence" which introduces a spreadsheet compiled scientists that summarizes representative knowledge about links between environmental exposures and human diseases. While extensive, it is not an exhaustive list. Of special value is the perspective it provides on the strength of the scientific evidence linking a given health condition with a particular chemical exposure. The accmpanying database is of particular value as it summarizes many links between chemical contaminants and about 200 human diseases, disorders, or conditions.
