- The key question is whether these naturallly occurring compunds break
- down at qualitatively different rates or or have radicallt different
- bioaccumulation ratios. The Greenpeace report does not claim that
- there are no natural organochlorine compounds, only that they are
- rare and "behave" differently since organisms have evolved in their
- presence.
