Effects from low-level concentrations of harmful chemicals preserved in three generations of fish
I've seen related findings going back many years but all too often we rely on short term high concentration toxicology testing. Increasing evidence is finding that persistent low level exposure to various chemicals can have important health consequences for the individual. This study finds that it is not only the individual that is affected but also the following generations. It is about endocrine disruptors, molecules which impact on hormonal functions. So the result isn't that surprising because hormones are very powerful molecules which are produced in relatively small quantities.
