Abstract
Inorganic contaminants present in waste streams may be removed by one of three methods, viz. physical, chemical or biological. Chemical and physical techniques have traditionally been employed to remediate such streams. However, due to the crisis of
rapidly deteriorating potable water quality, legislation governing the levels of contaminants is becoming progressively stricter. Therefore, alternative methods for treatment have been investigated. Biosorption technology, utilising any natural form of biomass to passively adsorb and immobilise solubilised heavy metals or radionuclides, offers such an alternative. However, the technology needs to effectively compete both on a cost and performance basis with existing methods before industry will accept and implement it. A pilot-plant feasibility study, using waste activated sludge to bioremediate a metal plating effluent, showed that the currently used method of chemical precipitation is more cost-effective. This paper describes the factors that must be considered when
selecting bioremediation as a cleanup technology for inorganics.

ABSTRACT
The present study was carried out to determine the concentrations of selected metal elements (lead, copper, manganese, zinc and iron) in 51 samples of commercial drinking water and tap water available in Malaysia. The results indicated that low metal elements were found in the studied water samples. Lead, manganese, zinc and iron were not detected in some of the studied samples, except copper. The concentrations of the metal elements in the studied samples were well below the maximum permitted concentrations as recommended. Therefore these drinking water are safe for consumption
and do not pose adverse effect to the health of consumers due to metal toxicity.
ABSTRAK
Kajian ini dijalankan untuk menentukan kandungan unsur logam yang terpilih (plumbum, gangsa, mangan, zink dan besi) dalam 51 sampel air minuman komersil dan air paip yang sedia ada di Malaysia. Keputusan kajian mendapati bahawa kandungan unsur logam adalah rendah dalam sampel air yang dikaji. Plumbum, mangan, zink dan besi tidak
terdapat dalam sebilangan kecil sampel yang dikaji, kecuali kuprum. Kandungan unsur-unsur logam dalam sampel yang dikaji adalah di bawah kandungan minima yang dibenarkan seperti yang disarankan. Oleh itu, air minuman yang dikaji adalah selamat untuk diminum dan tidak mendatangkan kesan buruk kepada kesihatan pengguna
disebabkan oleh keracunan logam.
