| Popis: | Acute and Chronic Effects of Hexachlorobenzene and Hexachlorobutadiene in Red Swamp Crayfish ( Procambarus clarki ) and Selected Fish Species. Laska, A. L., Bartell, C. K. Condie, D. B., Brown, J. W., Evans, R. L., and Laseter, J. L. (1978). Toxicol. Appl. Pharmacol. 43 , 1–12. Red swamp crayfish ( Procambarus clarki ), sailfin mollies ( Poecilia latipinna ), Gulf killifish ( Fundulus grandis ), and largemouth black bass ( Micropterus salmoides ) were tested for toxic responses to hexachlorobenzene (HCB) and hexachlorobutadiene (HCBD). HCB dissolved in water induced no observable effects on any test animals, whereas HCBD at concentrations of 1.2 and 4.2 mg/liter resulted in mortalities of 50% in mollies challenged within 138 and 26.5 hr, respectively. Injections of HCB dissolved in peanut oil were not acutely toxic to crayfish or Gulf killifish at a dose of 125 μg of HCB/g body weight. However, a 5-day LD50 in crayfish was 336 μg of HCBD/g body weight in injection experiments, while a 20-hr LD50 was 1700 μg/g body weight in Gulf killifish. Plasma cortisol concentrations were not significantly elevated in Gulf killifish following 10 days of exposure to 5.9 μ/liter of HCB. Higher plasma cortisol concentrations were observed in bass challenged with 31.95 μg-liter of HCBD for 10 days. |
