In the present study, the bioaccumulation of chromium, manganese, cobalt, copper, zinc, selenium, arsenic, strontium, cadmium, tin, antimony and lead in tissues of thirty marine fish species collected from New Ferry Whorf, Sassoon dock and Versova fishing harbour in Mumbai, India, were analysed. The bioaccumulation patterns of these twelve elements were determined to assess pollution biomarkers based on cellular and oxidative stresses. Catalase, superoxide dismutase and glutathione-s-transferase, glycolytic enzymes viz. lactate dehydrogenase and malate dehydrogenase, protein metabolism enzymes viz. aspartate transferase and alanine transferase, and lipid peroxidation were significantly higher in muscle and gill tissues. The activities of the neurotransmitter enzyme acetylcholine esterase in muscle and brain tissues was inhibited due to pollution. This study suggested that biochemical attributes such as oxidative stress enzymes, cellular biomarkers, neurotransmitter enzymes and metal and metalloid contamination could be successfully employed, even at low concentrations, as reliable biomarkers for biomonitoring of contaminated marine ecosystems.
在本研究中，分析了从印度孟买的纽费里沃赫夫、萨松码头和韦尔索瓦渔港采集的 30 种海洋鱼类组织中铬、锰、钴、铜、锌、硒、砷、锶、镉、锡、锑和铅的生物累积情况。根据细胞和氧化应激，确定了这 12 种元素的生物累积模式，以评估污染生物标志物。过氧化氢酶、超氧化物歧化酶和谷胱甘肽-s-转移酶、糖酵解酶如乳酸脱氢酶和苹果酸脱氢酶、蛋白质代谢酶如天冬氨酸转移酶和丙氨酸转移酶以及脂质过氧化作用在肌肉和鳃组织中显著升高。由于污染，肌肉和脑组织中的神经递质酶乙酰胆碱酯酶的活性受到抑制。本研究表明，即使在低浓度下，生物化学特征如氧化应激酶、细胞生物标志物、神经递质酶以及金属和类金属污染也可以成功用作受污染海洋生态系统生物监测的可靠生物标志物。
