| Summary: | Results from the present study in Kuala Terengganu,
Malaysia indicated a significant spatial variation
but generally the total suspended particulate concentrations
(mean = 17.2–148 lg/m3) recorded were below the recommended
Malaysia guideline for total suspended particulate
(mean of 24-h measurement = 260 lg/m3). Some of the
elemental composition of particulate aerosol is clearly
affected by non crustal sources, e.g. vehicular emission
sources. Based on correlation and enrichment analyses, the
elements could be grouped into two i.e. Pb, Cd and Zn group
with sources from vehicular emission (r[0.6; enrichment
factor[10) and Al, Fe, Mn and Cr group that appears to be
of crustal origin (r[0.6; enrichment factor\10). It can
also be concluded that the mean levels of Pb (1 ng/m3), Cd
(0.02 ng/m3) and Zn (2 ng/m3) in the study area are generallylower than other urban areas in Malaysia (Pb\181 ng/m3; Cd\6 ng/m3; Zn\192 ng/m3). |
