Coastal pollution has been increasing significantly over the recent years and found expanding environmental problems in many developing countries. Samples of mudskipper (Periopthalmus novemradiatus) were collected from various locations within the Palghar area and analyzed for heavy metal content using Calorimeter. The study was conducted from June 2021 to January 2022. The concentrations of key heavy metals, including lead (Pb), copper (Cu), chromium (Cr), were determined in different tissues of the mudskipper.The results revealed varying levels of heavy metal contamination in the mudskipper (muscles, liver and gills) from different sampling sites. Highest concentrations of lead, copper and chromium were estimated in mudskipper from different body and and different sites. Higher copper level in muscles 0.6843 gm/kg, chromium in liver 0.5625 gm/kg and lead 0.9734 gm/kg recorded in muscles from Mahim prawn culture farm. Even those were below than permissible values recommended by USFDA, FAO and WHO,
