ABSTRACTCurrent environmental issues include heavy metal contamination. Cadmium pollution in aquatic environments harms creatures and can pass to people through food chains. poisoning damages bones, kidneys causes cancer. Tubifex tubifex is a well-known water indicator because of its good adaptation power pollution. sp. chosen as the test animal this study since it an species also model non-target organism ecotoxicology. The aim present work assess toxicity cadmium nitrate on biomarker. Acute was analysed by measuring 96 h LC50 value. Physical observations revealed that induced autotomy caudal region worm more mucus secretion. Behavioural alterations like changes mucous secretion, clumping tendency wrinkling effect were observed cadmium-treated worms. Antioxidant enzymes level (MDA, CAT SOD) increased significantly exposure. In general, biomarker data show exposure has stress-related consequences at biochemical physiological levels, reducing overall health survival such animals.Highlights acute sub-acute levels investigated tubifex.The goal look effects oxidative stress behavioural biomarkers T. tubifexSublethal impact functioning annelids wild.KEYWORDS: Cadmiumacute toxicityTubifex tubifex; metaloxidative AcknowledgmentsWe are thankful Department Zoology, University Burdwan for providing laboratory facilities.Disclosure statementNo potential conflict interest reported author(s).Data availabilityThe datasets generated during and/or current available from corresponding author upon reasonable request.Additional informationNotes contributorsNeha MajumdarNeha Majumdar currently working Research Scholar Post Graduate Conservation Biology, Durgapur Government College, Paschim Bardhaman, West Bengal, India.
