The hazards of synthetic (anthropogenic) chemicals.
International Congress of Toxicology. Seattle, Washington USA, 1995/07/02.
Currently, there is a highly politicized debate on the comparative risks of naturally occurring and synthetic chemicals.
Since humans are often exposed to complex mixtures of both classes of chemicals, the real-world value of this debate is unclear.
However, in any such comparison, it is important to realize that some naturally occurring substances - such as lead or tobacco - have been so altered or disturbed by human activity that they are best considered as products of human activity, or anthropogenic.
Reasons for concern over synthetic and anthropogenic chemicals include :
persistence and propensity for long-term storage in biota and the environment ;
structural similarity to endogenous biomolecules ;
and additivity to natural hazards.
