Heavy metal concentration of freshwater fish on aquaculture activity at Pahang river and its potential health risk / Syahidah Mahaudin

Heavy metal in fish is one of the concern in food safety especially on aquaculture activity of freshwater fish as it may lead to a lot of adverse health effect to human. Pangasius hypophthalmus or Patin fish is a popular fish among people as being trademark for Temerloh District. This study aims to...
