This study aimed to compare the effects of crude oil and chemically dispersed crude oil on the antioxidant response and cell apoptosis in the respiratory tree of sea cucumber (Apostichopus japonicus). Results showed that compared to the water-accommodated fractions (WAF) of Oman crude oil, chemically enhanced WAF (CEWAF, Oman crude oil dispersed by Guangming-2 chemical dispersant) exposure caused a more significant reduction in the glutathione S-transferase (GST) activity and a more significant increase in the caspase-3 activity. Both WAF and CEWAF exposure had no overt impact on the peroxidase (POD) activity. Besides, Guangming-2 alone exposure caused no remarkable changes in the activities of GST, POD, and caspase-3. This study revealed that the addition of chemical dispersant to disperse crude oil could aggravate the negative effect of crude oil on antioxidant defense enzyme activities (especially GST) and cause severer cell apoptosis in sea cucumber. 2022, The Author(s), under exclusive license to Springer Nature Singapore Pte Ltd.
