pH Dependency of 2,4,5-Trichlorosphenol Toxicity

Abstract

Acute 96-h flow-through toxicity tests with the compound 2,4,5- trichlorophenol (TCP) were conducted using the annelid, Lumbriculus variegatus, as the test organism. Toxicity tests were conducted at three nominal pH levels of 7.0, 7.8 and 8.6 to generate LCSO values at 4, 8, 24, 48 72 and 96 h of exposure.
