Description

Laboratory studies are being conducted in which fish are exposed to defined concentrations of known chemicals. Natural steroids, synthetic steroids and xenoestrogens will be assessed. The choice of test chemicals will depend on field studies in the UK and Germany, which run more or less in parallel with the laboratory studies. This will resolve the question of whether we should be more concerned about the presence of natural and synthetic steroids or xenoestrogens in the environment.
