Abstract
This study was conducted to determine the level of atmospheric heavy metal pollution by using local mosses at Mount Kinabalu Sabah Malaysia. As for the records this is the first study of its kind in South East Asia. The objectives of this study were: a to use moss as an active biomonitoring organisms as a part of a monitoring study to assess the impact of metals associated with ambient particles on mosses at roadsides. b to investigate the accumulation of the metals on moss over a period of exposure and c to determine the effectiveness of moss as biological indicator The moss species that studied were Trismegistia calderensis Sull Broth and Trismegistia panduriformis C.H.Wright Broth. Moss bags techniques were used in this experiments. The moss samples were exposed at 3 difference zones roadside 2 km and 8 km over a period of 0 4 8 and 12 weeks for 3 -months for subsequent analysis of metal concentration Cd Cr Cu Pb and Zn The concentrations of heavy metals in the desiccated apical shoots of mosses were determined by atomic absorption spectrophotometry AAS. Chlorophyll concentrations were also analysed to measure the stress response of the moss. The results confirm that mosses would be very effective bioindicators of environmental metal concentrations because the concentration of metal in the moss rapidly and directly reflects the metal concentrations in the ambient air.
