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 microg/m(3)) recorded were below the recommended Malaysia guideline for total suspended particulate (mean of 24-h measurement = 260 microg/m(3)). 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/m(3)), Cd (0.02 ng/m(3)) and Zn (2 ng/m(3)) in the study area are generally lower than other urban areas in Malaysia (Pb < 181 ng/m(3); Cd < 6 ng/m(3); Zn < 192 ng/m(3)).
马来西亚瓜拉丁加奴的本研究结果表明存在显著的空间差异，但总体而言，所记录的总悬浮颗粒物浓度（平均值 = 17.2 - 148微克/立方米）低于马来西亚推荐的总悬浮颗粒物指南（24小时测量平均值 = 260微克/立方米）。颗粒物气溶胶的一些元素组成明显受到非地壳来源的影响，例如车辆排放源。基于相关性和富集分析，这些元素可分为两组，即来自车辆排放源的铅、镉和锌组（r > 0.6；富集因子 > 10）以及似乎源自地壳的铝、铁、锰和铬组（r > 0.6；富集因子 < 10）。还可以得出结论，研究区域内铅（1纳克/立方米）、镉（0.02纳克/立方米）和锌（2纳克/立方米）的平均水平通常低于马来西亚的其他城市地区（铅 < 181纳克/立方米；镉 < 6纳克/立方米；锌 < 192纳克/立方米）。
