Environmental Geochemistry and Health, 39, 1259-1271.https://repoemc.ukm.my/handle/123456789/992The aim of the present study was to appraise the levels of heavy metal contamination (Zn and Pb) in sediment of the Langat River (Selangor, Malaysia). Samples were collected randomly from 15 sampling stations located along the Langat River. The parameters measured were pH, redox potential, salinity, electrical conductivity, loss of ignition, cation exchanges capacity (Na, Mg, Ca, K), and metal ions (Zn and Pb).Geo-accumulation indexHeavy metalLead (Pb)River sedimentZinc (Zn) Sedimentquality guidelinesJournal
