A simple bioassay with artemia larvae to determine the acute toxicity of antifouling paints

, : A simple bioassay with artemia larvae to determine the acute toxicity of antifouling paints. Water Research 23(7): 893-898

The toxic effects on mollusc cultures, of chemicals leaching from coatings on the ship hulls of pleasure craft, has triggered substantial research on the hazard of antifouling paints for non-target biota. Conventional laboratory bioassays are mostly carried out on individual (pure) toxicants incorporated in such patients and thus do not stimulate the leaching the toxic-compounds from the antifouling coatings. In order to simulate such conditions, an attempt has been made to determine the toxicity of coated test panels to nauplii of the brine shrimp Artemia as test-species. The "surface-to-volume ratio" (S/V=coated surface of test panel to volume of seawater to the test-vessel) has been used as a criterion for determination of the S/V-LC50, which may be a useful approach for toxicity ranking of antifouling paints. This preliminary study explains the principles for a rapid and cost-effective bioassay for direct determination of the toxicity of surfaces coated with potentially hazardous compounds.
