Acute Toxicity of Chlorine to Selected Estuarine Species

Abstract
Two flowing water systems designed to test the acute toxicity of chlorine in estuarine water are described, one adapted for microscopic species, the other for larger species. Acute toxicity results for several invertebrate and fish species are presented. Molluscan larvae and Acartia tonsa were the most sensitive species tested, with 48-h TL50 values less than 0.005 ppm.
