Estimation of target hazard quotients and potential health risks for metals by consumption of shrimp (Litopenaeus vannamei) in Selangor, Malaysia

The concentrations of the heavy metal in Pacific white shrimp (Litopenaeus vannamei) purchased from the local wet markets throughout the state of Selangor were investigated using flame atomic absorption spectrometry. The order of the heavy metal concentrations were Zn>Cu>Pb>Cd, whereby the...
