  Author(s): A Alex Justin*, U Sangamesh and G Ananthan
  
  Heavy metal pollution from human activities has emerged as a global threat, with many metals released untreated into aquatic zones where they accumulate in organisms. In India's Vellar estuary, the oyster Crassostrea madrasensis provides food and income for local communities, while filtering water. This study analyzed oyster tissue to determine levels of five heavy metals and five essential minerals, assessing potential human health risks and the estuary's ecosystem health. Atomic absorption spectroscopy revealed manganese at 11.0121 µg/L, 10 times higher than lead. Calcium was most abundant among minerals at 371.7 µg/L. All metals and minerals were within safe levels for human consumption according to UN Food and Agriculture Organization standards. However, as a breeding ground for commercially valuable species, periodic monitoring of accumulation is.. View more»
