The toxicity of Pentron D-90, a low-molecular-weight polyacrylamide-based ferrous sulphate compound, was evaluated by standard 96-hour static bioassays, in order to assess the environmental impact of its use for corrosion control in power stations. Juvenile Atlantic menhaden, spot and blue crabs from the estuary of the Patuxent river, Md. , were used as test organisms. The results showed that no toxicity from iron would be expected to occur to fish and crabs, when the compound is used at 5 mg per litre, and that no other component is toxic to the animals over a 96-hour period, at the anticipated rate of use.
