The concentrations of lead, cadmium, and mercury were analyzed seasonally in muscle tissues of Perna viridis (tahong) sold in the old and new public markets in Batangas City, Philippines. Cadmium concetration in Perna viridis collected from the old and new public markets during wet season were significantly higher than in dry season. The mean cadmium concentrations in Perna viridis taken from old and new public markets during wet season were significantly lower compared with the maximum allowable level set by the Food Standards Australia and New Zealand (FSANZ). Based on a person's average diet, the heavy metal concetration detected in the study are within the provisional tolerable weekly intake (PTWI) but can still impose detrimental health risks if continuous consumption is exercised.
