Result shows that 33% of sample analysed were contain toxic levels of cadmium, 40% were contain toxic levels of lead and no sample posses arsenic above the limit. (limit of cadmium, mercury and lead were 0.3,0.5 and 10 µg/g, respectively)
Keywords: Atomic absorption spectrophotometry; Cadmium; Lead; Mercury; Quality; Toxic metals
