ABSTRACT

Surface sediment samples from 2 transects (20 sampling points) of Tanjung Lumpur mangrove forest were analyzed for the concentrations of Pb, Cu, Co and Mn. In this study, the average concentrations of Pb, Cu, Co and Mn were 44.41 μg/g dry weight, 32.79 μg/g dry weight, 5.79 μg/g dry weight and 117.73 μg/g dry weight, respectively. The calculated enrichment factors (EF) obtained for Co and Mn can be considered to have the terigeneous in sources while Pb and Cu are considered to have anthropogenic input.

Keywords: Co; Cu; enrichment factors; Mn; Pb; Tanjung Lumpur

ABSTRAK

Sampel sedimen permukaan daripada 2 transek (20 sampel) dari hutan paya bakau Tanjung Lumpur diukur kepekatan Pb, Cu, Zn dan Co. Dalam kajian ini, purata kepekatan Pb, Cu, Co and Mn adalah masing-masing 44.41 μg/g berat kering, 32.79 μg/g berat kering, 5.79 μg/g berat kering dan 117.73 μg/g berat kering. Nilai faktor pengayaan (EF) yang diperolehi bagi Co dan Mn boleh dianggap terhasil daripada sumber terigenus semula jadi manakala logam Pb dan Cu didapati mempunyai sumber input antropogenik.

Kata kunci: Co; Cu; faktor pengayaan; Mn; Pb; Tanjung Lumpur
