摘要
为了研究重金属-营养盐-石油烃复合污染下菲律宾蛤仔(Ruditapes philippinarum)的代谢特征及其过氧化物歧化酶(SOD)活性,判断其用于复合污染生态修复的可能性。以海沙模拟菲律宾蛤仔生境,将其暴露于重金属-营养盐-石油烃复合污染,测定其耗氧率、排氨率和SOD活性。结果表明:氨氮和汞对菲律宾蛤仔耗氧有协同增益作用;氨氮促进菲律宾蛤仔氨氮排泄;SOD活性不受重金属、营养盐和石油烃的影响。考虑到菲律宾蛤仔对重金属、营养盐和石油烃的耐受性及富集特性,认为菲律宾蛤仔是修复重金属-营养盐-石油烃复合污染的潜在物种。
To judge the potential utilization of Manila clam Ruditapes philippinarum for bio- restoration,Manila clam was exposed to multiple-contamination of heavy metals, nutrients and petroleum, during which itsinhabits were simulated by sand, and metabolism characteristics and activity of superoxide dismutase of Manilaclam were measured. The results showed that there were synergistic effects of ammonia and mercury on oxygenconsumption of Manila clam; ammonia excretion rate of the clam was promoted by ammonia; there was nosignificant effect of heavy metals, nutrients and petroleum hydrocarbon on superoxide dismutase activities.Because of tolerances and bio- accumulations of Manila clam to heavy metals, nutrients and petroleumhydrocarbon, Manila clam might be used for bio- remediation of multiple- contamination of heavy metals,nutrients and petroleum hydrocarbon.
