“…Nevertheless, precaution must be taken as M. meretrix at Batu Payung seemed to be inclined to accumulate cadmium in its soft tissues compared with other selected heavy metals in this study, even though the presence of cadmium is low in the environment as compared with other analyzed heavy metals studied. Cadmium bioavailability in sediments is related to the cadmium mineral composition, which influenced the accumulation rate of cadmium into M. meretrix tissues (Wu, Xie, Xu, Wang, & Jia, 2013). The smallest cluster size (30.00–34.99 mm) of M. meretrix BSAF for cadmium was almost close to value 1.…”

Meretrix meretrix can accumulate heavy metals from the contaminated environment in its tissues and passed on these elements through the food chain, which can cause health hazards. The mean size distribution of the M. meretrix wild population at Batu Payung, Tawau, North Borneo, was determined by the linear morphometric analysis of outer shell length, and bivalve was categorized by the outer shell length size at 5-mm interval cluster groups. The selected heavy metals concentration in wild M. meretrix whole tissues was determined by an Induced Couple Plasma-Optical Emission Spectrometer (ICP-OES) to provide baseline data for policymakers and stakeholders to formulate sustainable harvest management. The largest group of outer shell size (45.00-50.00 mm) had the concentration of the least heavy metals in its tissues among other smaller shell size cluster groups, indicating M. meretrix outer shell length size of more than 45 mm cleanse excessive heavy metals out of their body more efficiently. A negative correlation between nonessential heavy metals (Cd, Pb) concentration in M. meretrix edible tissues and its outer shell length size signified that the largest group of outer shell size was safer to consume. M. meretrix is also facing overfishing like elsewhere in North Borneo.
