Heavy metals
concentration in fishes of Lake Chini was monitored for within a span of the
years in 1990, 1999 and 2000. Fishes in the lake are taken by indigenous and
local people as part of their diet, therefore necessary to determine metal
concentrations in fish. A total of nine
fish species were analysed for lead (Pb), zinc (Zn), copper (Cu) and cadmium
(Cd) concentration in fish tissues. The extraction procedure follows that
carried out by Agemian et al, (1984), while the preparation, extraction and
metal determination were done following standard method (APHA, 1985). The
metals concentration in fish tissues was lower than the maximum allowable
concentration in Malaysian food guideline (Malaysian Food Act, 1983). The mean
concentration for Pb, Zn, Cu and Cd in fish tissues are 0.56 ± 0.28 mg/kg, 3.02
± 0.78 mg/kg, 0.38 ± 0.31 mg/kg and 0.18 ± 0.07 mg/kg respectively. Although
little variation of concentrations was detected from different species, the
variation was not significant. One-way ANOVA test indicates that metals
concentration were not significant different between sampling date (p > 0.05). Lake Chini was characterised
as having a low Pb, Zn, Cu and Cd concentrations in fish and is considered save
for local consumption.
