Abstract
The toxicity of sodium pentachlorophenate to early life stages of steelhead trout (Salmo gairdneri) was investigated, using a flow-through exposure system. A 96-hr LC50 of 66 micrograms/l was derived for previously unexposed ten-week-old fry. A 72-day test, beginning 24 hr after fertilization, yielded a chronic toxicity threshold of 14 micrograms/l. These results, and the acute/chronic ratio of 4.7, compare reasonably well with values in the literature. Yolk sac edema and cranial malformations, which are commonly observed in chronic tests with technical grade pentachlorophenol, were rate in this test with purified (99%) material.
