The concentration and distribution of mercury in environmental samples (sea water, rock, sea sand, sediment, soil, fish and etc.) taken from various coastal sea areas and its ambient area in Malaysia were investigated. Mercury in environmental samples was subjected to the reduction-vaporization using of tin (II) chloride and heating-vaporization method. The mercury vapor was concentrated with a porous gold collector. Afterwards, mercury vapor evolved from the heated collector was determined by cold vapor atomic absorption spectrometry. In coastal sea water of Malaysia, the geometric mean of inorganic mercury and inorganic mercury plus organic mercury were 3.5_2 and 3.9_8ng l^<-1> which are 1.9 and 1.7 times higher than those for the East China Sea, respectively. Arithmetic and geometric mean values of total mercury concentration in sea and river sediments were 30.4 and 20.1 μg kg^<-1>, respectively, and the polluted river sediments in Port Kelang was about one order higher than both of these mean. In fish meat, the chemical form of mercury was mainly organic mercury and the inorganic mercury was negligible. Mercury concentration was high in carnivorous fish such as sharks and crabs compared to other fish species. |
