TOXICITY OF 2,4,5-TRICHLOROPHENOL TO THE ANNELID LUMBRICULUS VARIEGATUS AT THREE VALUES OF pH

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.
