摘要
A study on Zn and Cu concentrations in 2 species of intertidal crabs, namely Uca annulipes and Dotilla myc-tiroides collected from the intertidal coastal area of Selangor (5 sites) and Negeri Sembilan (3 sites) , west coast of Pen-insular Malaysia, was carried out. The various localized sources of Zn and Cu discharges towards both the crab species were mentioned. A comparative study between the 2 crab species also revealed that the concentrations of Zn and Cu were significantly (P <0.05) higher in U. annulipes when compared to D. myctiroides. This difference was related to the or-ganic matter percentage in the crabs' microhabitat sediments since metals can be associated with the orgarlic matter of sediments in which they might ingest. Significantly ( P <0.05) higher organic matter content was shown in U. annulipes sediments when compared to D. myctiroides sediments for all stations. The metal and size relationship in the crabs was al-so investigated. The relationships between Zn and Cu concentrations with body weight and carapace width of U. annulipesand D. myctiroides were significantly ( P <0.01 and P <0.05) correlated although the pair wise was weak.
