  • The impact of pesticides on freshwater creatures

    A recent study has concluded that, although spray drift of pesticides can have short-term effects on individual stream-dwelling invertebrates, there is no evidence to suggest that there is an impact on populations as a whole. However, to reduce the impact of the pesticides on these organisms, a no-spray buffer zone is shown to be a simple and effective measure. Pesticides play an important role ...
