Abstract
Abstract Noted as one of the fastest growing capital cities among the developing countries, Kuala Lumpur faces a tremendous threat of being greatly exposed to problems of heavy metal pollution in its air, water, soil, sediment and the limited vegetation. Three factors enhance the increasing deposition of heavy metals in Kuala Lumpur: its geographical location; its rising importance as an economic and industrial center; and the ever increasing automobile population. This paper, based on a cumulative study over a period of several years, examines the problems of heavy metal pollution in various environmental sinks, taking into consideration several underlying perspectives. The 2 aspects of the metal pollution emphasized are: (a) ground analysis relating to the air pollution in the city proper; and (b) metal speciation studies. The metals analyzed were from samples of soil, water, sediment, and biological materials taken at several chosen sites in the city, using atomic absorption spectrophotometer and neutron activation analysis. The metals are considered from their chemical behaviour view-point, and crosslines are made with other environmental parameters measured including biophysical indices.
