Why did you measure substances for which there is no documented
health or ecological effect?
Environmental research should not progress on a single front. Clearly,
for those compounds for which health or ecological effects are well
known, there is reason to undertake environmental studies of their movement
and distribution. But, at the same time, studies need to be done to
evaluate the movement and distribution of potentially harmful substances
regardless of the state of knowledge about their health or ecological
effects. The results of this study will be used to prioritize research
on the health and ecological risks of these chemicals.
