EFFECT OF PH ON THE ACUTE TOXICITY OF 2,4,5-TRICHLOROPHENOL TO THE RAINBOW TROUT ONCOHYNCHUS MYKISS

Abstract

Acute 96-h flow-through toxicity tests with the compound 2,4,S­ trichlorophenol (TCP) were conducted using rainbow trout Oncorhynchus mykiss 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.
