ABSTRACT

The selected trace metals in the soft tissue of Thais clavigera from 11 sampling sites along the coastal waters of the east coast of Peninsular Malaysia were studied. Significant inter-spatial variations in trace metals were recorded. Sites with relatively high concentrations of the contaminant metals Hg, Cd, Pb and Zn are correlated to their close proximity to industrial and urban sites or to boating and aquaculture activities. This could possibly be contributed by the highly growth of industrial activities like port and sewage release. Interspatial comparison with previous studies indicated lower measurement. Meanwhile, comparison with other studies around the world also designated lower values except for Zn. The metal accumulation patterns indicated an enrichment of essential metals over non-essential metals. Comparison of metal concentration with maximum permissible limits of toxic metals in food established in different countries, as well as Malaysian Food Act 1983 and Food Regulations 1985 Fourteen Schedule, indicated the values were well within safety levels.

ABSTRAK

Logam surih yang terpilih dalam tisu badan Thais clavigera di 11 lokasi persampelan di sepanjang pantai timur Semenanjung Malaysia telah dikaji. Perbezaan logam surih yang signifikan antara lokasi telah direkod. Lokasi yang secara relatifnya mempunyai kepekatan logam Hg, Cd, Pb dan Zn tercemar yang tinggi adalah berhubung kait dengan lokasi kawasan tersebut sama ada berdekatan dengan kawasan industri dan perbandaran atau aktiviti perkapalan dan akuakultur. Ini berkemungkinan disumbangkan oleh pertumbuhan tinggi dan aktiviti pengindustrian seperti pelabuhan dan pelepasan sisa. Perbandingan antara lokasi dengan kajian pada masa lepas menunjukkan nilai yang rendah. Sementara itu, perbandingan dengan kajian lain di seluruh dunia juga menunjukkan nilai yang rendah kecuali Zn. Corak pengumpulan logam menunjukkan pengkayaan logam perlu ke atas logam bukan penting. Perbandingan kepekatan logam dengan paras logam toksik maksimum yang dibenarkan di dalam makanan yang digubal di beberapa negara, serta Akta Makanan Malaysia 1983 dan Peraturan Makanan 1985 Jadual Empat Belas, menunjukkan bahawa nilai di dalam kajian masih di bawah paras selamat.

Kata kunci: Logam berat; paras keselamatan makanan; perairan pantai Pantai Timur Semenanjung Malaysia; Thais clavigera
