ABSTRACT
Concentrations of cadmium and lead in Colocasia esculentum and Panicum repens at four selected locations (Stations 1, 3, 4 and 5) along Linggi River, Malaysia were determined by Atomic Absorption Spectrophotometry (AAS) after digestion of the plant samples with dilute nitric acid. The concentrations of lead in both the Colocasia esculentum and Panicum repens were relatively higher (p<0.05) than those of cadmium in the same species at all the stations along the Linggi River. The mean concentrations for cadmium and lead found in this study were 0.056 + 0.017 mg/kg and 0.624 + 0.173 mg/kg respectively. The upstream areas, in this case, being represented by Station 1 (Pantai) was relatively the least polluted in terms of cadmium and lead when compared to other stations along the river. The source of pollution for both metals came mainly from Station 3 (Seremban) and Station 4 (Mambau) where most of the factories and industries were located. Colocasia esculentum seemed more suitable as a bio-indicator for the study of cadmium and lead as compared to Panicum repens, because the former satisfied most of the bio-indicator criteria.
