Oxidative Stress in Shellfish Sinonovacula constricta Exposed to the Water Accommodated Fraction of Zero Sulfur Diesel Oil and Pinghu Crude Oil

Oxidative Stress in Shellfish Sinonovacula constricta Exposed to the Water Accommodated Fraction... This study investigated the oxidative stress of the water accommodated fraction (WAF) of zero sulfur diesel oil and Pinghu crude oil on Sinonovacula constricta, respectively. The oxidative stress of oil pollutants on organisms was measured by typical antioxidases, such as SOD, CAT, GST, and POD. Toxicity was quantitatively evaluated by combining IBR (integrated biomarker responses). Results demonstrated that different concentrations of oil caused different degrees of induction to the four antioxidases. Compared with the control group, all test groups presented enzyme induction or inhibition during exposure period. Combined with the calculated IBR values, the high-concentration group of the zero sulfur diesel oil could cause the largest biological effect changes, which reflected its high oxidative stress. The zero sulfur diesel oil had stronger toxicity than Pinghu crude oil. http://www.deepdyve.com/assets/images/DeepDyve-Logo-lg.png Archives of Environmental Contamination and Toxicology Springer Journals

Abstract

This study investigated the oxidative stress of the water accommodated fraction (WAF) of zero sulfur diesel oil and Pinghu crude oil on Sinonovacula constricta, respectively. The oxidative stress of oil pollutants on organisms was measured by typical antioxidases, such as SOD, CAT, GST, and POD. Toxicity was quantitatively evaluated by combining IBR (integrated biomarker responses). Results demonstrated that different concentrations of oil caused different degrees of induction to the four antioxidases. Compared with the control group, all test groups presented enzyme induction or inhibition during exposure period. Combined with the calculated IBR values, the high-concentration group of the zero sulfur diesel oil could cause the largest biological effect changes, which reflected its high oxidative stress. The zero sulfur diesel oil had stronger toxicity than Pinghu crude oil.
