The present study delineate the various biochemical and histopathological tool to evaluate as strong biomarker in the field
condition for detection of the least and maximize level of pollution and contamination. We have collected Labeo rohita from
13 different sites from East Kolkata wetland to determine biochemical and histopathological status to analyse metal contamination
in the significant biological hot spot EKW. The biochemical marker as antioxidative status, i.e., catalase, superoxide
dismutase (SOD), and glutathione-S-transferase (GST) in liver and gill, were remarkably higher (p < 0.01) at some of the
sampling sites, but catalase in brain, SOD in kidney, GST in brain and kidney, and neurotransmitter as acetylcholine esterase
(AChE) in brain were not significant (p > 0.05) among the sampling sites. The glycolytic enzymes, such as lactate dehydrogenase
(LDH) and malate dehydrogenase (MDH) in liver, gill, and muscle, and protein metabolic enzymes, such as alanine
amino transferase (ALT) and aspartate amino transferase (AST) in liver, gill, muscle, and kidney, were noticeably higher
(p < 0.01) at some of the sampling sites. The histopathology of the liver and gill were altered at different sampling sites, such
as blood congestion, leucocyte infiltration with parenchymal vacuolisation, nucleus with blood vessels, hepatocytes granular
degeneration, haemorrhage, karyorrhexis, shrink nucleus, and pyknotic nuclei in liver. In the gill, structural changes, such
as complete destruction and shortening of secondary gill lamellae, blood vessel in gill arch, curling of secondary gill lamellae,
aneurism in gill lamellae, and neoplasia, were observed. Most of the metals were found within the safe limit all along
the 13 sampling sites, indicating that fishes are safe for the consumption. Based on our finding, we could recommend that a
rational application of biochemical profiles, such as oxidative and metabolic stress parameters, including histopathology to
be used as biomarkers for biomonitoring the metal contamination in the aquatic environment.
