Abstract
Biomonitoring uses living organisms to assess environmental quality and being preferred over conventional methods that use fully or semi-automatic gauges for its lower cost and practicality. Recently, higher plants are widely used for biomonitoring purposes by means of their species identification simplicity, larger availability of biological substantial, and easy to sample. In this study, samples of Hevea brasiliensis (i.e leaves, barks, and latex as well as surrounding soils) from outskirts of Pelangai, Bentong were tested for heavy metals by using inductively coupled plasma optical emission spectroscopy (ICP-OES). Enrichment factor of soils indicated that some metals (B, Ca, Cu, Mn, Pb, Zn, As and Na) were anthropogenic which most likely originated from traffic emissions. In addition, leaves trapped the most heavy metals compared to barks and latex. The accumulation of pollutants in those samples has identified biomonitoring abilities of Hevea brasiliensis.Biomonitoring uses living organisms to assess environmental quality and being preferred over conventional methods that use fully or semi-automatic gauges for its lower cost and practicality.
