摘要：Cement industry is one of the main sources of particulate matter (PM). This study is aimed to identify the distribution pattern of density PM production in Rawang. This paper presents comparison of samples in terms of several weather parameters in which the temperature, wind velocity and humidity. This survey was carried out in the region of Rawang using the primary and secondary data. The primary data was obtained from the field observation of PM10 and PM2.5, temperature, humidity and wind velocity in Rawang within 11 observation site locations. The secondary data was obtained from several published documents, articles and journals. The data were analyzed using descriptive statistics which includes mean, median, maximum, minimum, and standard deviation. Finding shows that the average concentration in the central location of the study increases in both parameters which refers to PM10 of 119.31 µg/m3 and PM2.5 of 35.44 µg/m3. This indicated that the level of particles concentration in the region of Rawang was critical.
