Evaluation of the pollution pressures posed by groups of chemicals on British riverine invertebrate populations

open access: yesBiological Reviews, EarlyView.
ABSTRACT Globally, rivers receive a diverse range of chemicals, including metals, pesticides, persistent organic pollutants, petrochemicals, human and veterinary pharmaceuticals and personal care products. However, the extent to which these different chemical groups affect riverine invertebrate communities is not well defined.
