The Carcinogenic Potency Project , which is a part of the US EPA 's Distributed Structure-Searchable Toxicity ( DSSTox ) Database Network , has been systemically testing the carcinogenicity of chemicals , both natural and synthetic , and building a publicly available database of the results since the 1980s . Their work attempts to fill in the gaps in our scientific knowledge of the carcinogenicity of all chemicals , both natural and synthetic , as the scientists conducting the Project described in the journal , '' Science '' , in 1992 : Chemistry professor writes that historically chemists have experienced chemophobia from the population at large , and considers that it is rooted both in irrational notions and in genuine concerns ( such as those over chemical warfare and industrial disasters ) . Professor Gordon Gribble has written that the start of chemophobia could arguably be attributed to '' Silent Spring '' , and that subsequent events such as the contamination of Times Beach and the disaster at Bhopal , India only exacerbated the situation
