Parental exposure of the freshwater snail Planorbella pilsbryi to copper results in transgenerational effects in offspring

Although not assessed in standard ecotoxicological tests, exposure to a toxicant that does not result in an observable adverse effect in the parents may lead to transgenerational effects. These are adverse effects observed in unexposed offspring as a result of their parents' exposure to a toxicant. The goal of this study was to investigate whether transgenerational effects are observed in freshwater snails exposed to a toxicant. Using copper …
