Salinity Dependence of Vanadium Toxicity against the Brackish Water Hydroid Cordylophora caspia

摘要

Vanadium, an abundant metal, enters the environment through natural rock weathering or by combustion of oil prod- ucts. A third pathway is the leaching of vanadium-rich building materials. Stones made from steel industry residual slags so- called slag stones, contain rather large amounts of vanadium. The increasing use of these slag stones in riverbank reinforce- Mant has therefore led to increased interest in the toxicity of Vanadium to aquatic organisms. The aim of the study was to Determine the toxicity of vanadium to the brackish water hydroid Cordylophora caspia and the effect of vanadium on the mem- Brane-bound enzyme Na, K-ATPase at various salinities.
