Program pemantauan memantau hubungan kepekatan dalaman dan luaran zarah halus (PM2.5). Empat sekolah dipilih dalam kajian ini. Kepekatan bahan zarahan halus telah dipantau di kelas yang berlainan dengan tahap lantai yang berbeza. Kepekatan PM2.5 dipantau berhampiran dengan sampingan untuk menentukan sama ada lalu lintas menjejaskan kepekatan dalaman PM2.5 di lokasi ini. Sumber-sumber lain yang ada di sekitar lokasi pemantauan juga dipertimbangkan. Kepekatan PM2.5 dikumpulkan di Sekolah Kebangsaan Bayan Lepas, Sekolah Kebangsaan Tasek Gelugor, Sekolah Menengah Kebangsaan Mutiara Impian dan Sekolah Kebangsaan Machang Bubok. Program pemantauan telah dilancarkan pada 16 Januari 2018 dan diteruskan sehingga 13 Mac 2018. Data pemantauan di tingkat lantai yang berbeza telah diambil secara berselang dengan selang 15 minit. E-sampler diletakkan di belakang kelas dan E-bam diletakkan di luar sekolah berdekatan dengan jalan raya. Maklumat meteorologi dikumpulkan menggunakan dua instrumen dan maklumat trafik terus dikumpulkan melalui kamera video di atau berhampiran tapak pemantauan yang menghadap ke jalan. Data yang direkodkan menggunakan monitor spesifikasi dianalisis menggunakan perisian SPSS untuk menentukan hubungan di dalam rumah dan di luar rumah PM2.5 dan perbezaan kepekatannya di tingkat lantai yang berbeza. Analisis nisbah dalaman / luaran (I / O) adalah 0.74 dan 0.76 pada tingkat dua tingkat dan tingkat ketiga Sekolah Kebangsaan Bayan Lepas yang menunjukkan sumbangan dari sumber luar ke arah kepekatan dalaman PM2.5. Sebaliknya, tiga sekolah lain menunjukkan sebaliknya. Berdasarkan analisis pembahagian, sumbangan sumber jalan raya tidak begitu kuat berdasarkan keputusan dianalisis dengan menggunakan Korelasi Pearson.

The monitoring program monitored the relationship of indoor and outdoor concentrations of the fine particles (PM2.5). Four schools were selected in this study. The concentration of fine particulate matter was monitored at different classes with different floor level. PM2.5 concentrations were monitored in close proximity to a road side in order to determine whether traffic affect indoor concentration of PM2.5 at this location. Other existing possible sources around the monitoring location were also considered. PM2.5 concentrations were collected at Sekolah Kebangsaan Bayan Lepas, Sekolah Kebangsaan Tasek Gelugor, Sekolah Menengah Kebangsaan Mutiara Impian and Sekolah Kebangsaan Machang Bubok. The monitoring program was launched on January 16, 2018 and continued until March 13, 2018. The monitoring data at different floor level was taken intermittently with 15 minutes interval . E-sampler was positioned at the back of the classroom and E-bam was positioned at outside of the school near to the roadway. Meteorological information was collected using two instruments and traffic information was continuously collected via video camera at or near the monitoring site facing to the road. The data recorded using the specification monitor were analyzed using SPSS software to determine the relationship of the PM2.5 indoors and outdoors and its differences of the concentration at different floor level. The indoor/outdoor (I/O) ratio analysis were 0.74 and 0.76 at second floor level and third floor level of Sekolah Kebangsaan Bayan Lepas which shows the contribution from the outdoor sources toward the indoor concentration of PM2.5. In contrast, the other three schools show vice versa. Based on the apportionment analysis, the contribution of roadway sources are not really strong based on the result analysed using Pearson Correlation.
