摘要：There has been no follow up reports up to date regarding the heavy metal concentration in the
blue swimming crab Portunus pelagicus from Manila Bay. Hence, this study aimed to provide a recent
status on the concentration of heavy metals (Cd, Cr, Pb, and Hg) in the muscular tissues of P. pelagicus
from Manila Bay, Philippines. Specimen samples were collected in August 2017 at the coastal area of the
bay, immediately brought to the laboratory, morphologically identified, dissected for muscles, and
subjected to heavy metal testing. Tissue samples were subjected to Flame-AAS (atomic absorption
spectrophotometry) method for detecting and quantifying heavy metals such as total cadmium (Cd),
total chromium (Cr), and total lead (Pb) while the analysis of total mercury (Hg) were done using the
Cold Vapor-AAS method. P. pelagicus in Manila Bay did not exhibit any serious deformities and signs of
visceral necrosis. With reference to a previous study, our study obtained a lower total Cd but higher in
terms of total Cr and total Pb while total Hg concentration is below detectable limit. P. pelagicus tissues
has tolerable levels of Cd, Cr, Pb, and Hg with reference to international/national standards. Still, it is
recommended to have a follow up monitoring of heavy metals in fish and shellfish commodities in Manila
Bay as a mitigating measure.
