Laboratory soft bottom microcosms, containing sediment with natural populations of meio-
and microfauna and the amphipod Pontoporeia affinis Lindström, were used to investigate …

The chronic toxicity of Cd was reduced by an increase in water hardness from 58 to 116
mg/l; a further increase in hardness to 230 mg/l, however, had no further effect on chronic Cd …

Acute and chronic ecotoxic effects of organophosphorous insecticide malathion (Fyfanon 50
EC 500 g L− 1) were investigated on three strains of Daphnia magna. The nominal effective …

Seven‐day‐static‐renewal tests with fathead minnow larvae (Pimephales promelas) and
Ceriodaphnia dubia were conducted monthly and results were used to assess …

Studies assessing the tolerance of the Asiatic clam, Corbicula spp., to a variety of chemical,
environmental, and physical stressors are summarised and reviewed. A majority of the …

In the toxicant bioassays, invertebrates with special reference to aquatic arthropod species
have been of recent interest as test models due to the need for developing nonmammalian …

This study investigates the use of concentration-time-response surfaces as a tool to predict
potential long-term effects of metals to Daphnia magna, using mortality as an endpoint …

Traditionally, aquatic toxicity studies examine the toxicity of a single chemical to an
organism. Organisms in nature, however, may be exposed to multiple toxicants. Given this is …

Four species of freshwater clam, Anodonta anatina, A. cygnea, Unio pictorum, and U.
tumidus were exposed for 2 weeks to acidified soft water (pH 4.0–4.5, Ca 4.6 mg/L) and for 4 …

Typically, the sublethal effects of exposure to environmental contaminants are assessed by
measuring the responses of one, or few, biochemical or physiological systems within …
