Temporal relationship between particulate matter (PM10) and carbon monoxide (CO) in Kuala Lumpur

Temporal relationship between particulate matter (PM10) and carbon monoxide (CO) in Kuala Lumpur / Nurul Adyani Ghazali
Pencemaran udara pada masa kini sudah menjadi satu fenomena yang tidak asing lagi di bandar raya Kuala Lumpur. Sebagaimana yang diketahui, pencemaran udara merupakan fenomena yang merbahaya dan mengancam kualiti kehidupan serta alam sekitar. Tujuan kajian ini dijalankan ialah untuk memahami corak perubahan kepekatan PM10 dan CO di dalam lingkungan rangkaian set masa di stesen permonitoran terpilih. Stesen ini terletak di salah sebuah bandar di Malaysia iaitu Kuala Lumpur dan mempunyai jaringan lalulintas yang sibuk. Data kepekatan bagi PM10 dan CO dicerap setiap jam dan setiap hari selama 8 bulan bermula dari bulan Januari sehingga bulan Ogos. Data yang dicerap ini akan di manipulasikan ke dalam bentuk set data berkala. Dengan membuat analisis secara statistik dan analisis menggunakan graf, data-data tersebut akan dianalisis dan akhirnya variasi kepekatan bagi PM10 dan CO akan dapat di takrifkan. Daripada kajian yang telah dijalankan, didapati paras persekitaran ambien CO adalah rendah berbanding paras persekitaran ambien bagi PM10. Berdasarkan analisis yang dibuat didapati nilai purata kepekatan CO sepanjang 8 bulan ialah 2.52 ppm sementara nilai purata bagi PM10 pula ialah 77.64 g/m3. Paras kepekatan CO adalah jauh lebih rendah berbanding dengan nilai had standard maksimum yang dibenarkan untuk persekitaran ambien iaitu 30 ppm untuk tempoh purata satu jam seperti yang telah ditetapkan dalam ‘Malaysian Guidelines’. Sementara itu, kepekatan purata bagi PM10 pula adalah tinggi tetapi masih berada dalam lingkungan had standard yang dibenarkan seperti tertakhluk dalam ‘Malaysian Guidelines’ iaitu tidak melebihi had standard maksimum 150 µg/m3 untuk tempoh purata 24 jam. _______________________________________________________________________________________________________ Air pollution is now becoming a common feature in Kuala Lumpur city. It has assumed an important level to the proportion that the city populace recognises its presence. The future of air pollution in the city seems to be bleak. From one stand point, air pollution although dangerous and threatening to the quality of life and environment, it is a luxurious problem and relatively remote in priority to the general public. This research is carried out to understand the changes in trend of particulate matter (PM10) and carbon monoxide (CO) concentration within a set time frame or limit in the selected monitoring sites which is located in heavily trafficked urban area of Malaysia which is Kuala Lumpur. Hourly and daily concentration of particulate matter and carbon monoxide are collected over an 8-month period from January to August. By using the statistical and graphical analysis, the data will be analysed and as the results, the variation of concentration for both particulate matter (PM10) and carbon monoxide (CO) will be define from the analysis. From the research, the results shows that the ambient level of carbon monoxide was relatively low as compared to the particulate matter. Based on the analysis, it was found that the annual average CO value is 2.52 g/m3 while the annual average PM10 value is 77.64 g/m3. It was shows that average PM10 levels in Kuala Lumpur network are generally higher than average CO levels. The concentrations levels of CO were far below the maximum limit of 30 ppm for one hour averaging time set by the Malaysian Guidelines. On the other hand, the PM10 mean concentration was higher but still not exceed the maximum limit 150 µg/m3 for the 24 hour averaging time which also set by the Malaysian Guidelines.
