Item Restricted Assessment of metals contamination in Klang River surface sediments by using different indexes(Thai Society of Higher Eduation Institutes on Environment, 2011) Abolfazl Naji; Ahmad IsmailSurface sediments (0-5 cm) from 21 stations throughout Klang River were sampled for metal concentration as well sediment's pH, total organic carbon (TOC) and particles sizes to obtain an overall classification of metal contaminations in the areaItem Open Access Metals fractionation and evaluation of their risk connected with urban and industrial influx in the Klang River surface sediments, Malaysia(Thai Society of Higher Eduation Institutes on Environment, 2012) Abolfazl Naji; Ahmad IsmailIn the present study, concentration, distribution and speciation of trace metals were conducted to assess the overall classification of Ni, Cu and Pb as well as their risk status in the surface sediments of Klang River. Sequential extraction technique (SET) was used to evaluate the four (exchangeable, acid-reducible, oxidisable-organic and residual) fractions of the surface sediments.
