Determination of Particulate Matter and Toxic Gaseous in Ambient Air Adjacent to Industrial Area

Abstract

A B S T R A C TAir quality in the residential areas adjacent to the industrial regions is of great concern due to the association with particulate matter and toxic gaseous which has adverse effects on human health. Therefore, the present study aimed to investigate the air quality in term of PM10 concentrations and toxic gaseous (CO and NO) at University Hussein Onn Malaysia (UTHM) residential college which is adjacent to a wood processing, electronic and fibre board factories. Four Stations defined as Station 1 (KKM), Station 2 (KKP), Station 3 (KKTDI) and Station 4 (KKTU) were selected for this investigation. PM10 concentrations were measured using the E-Sampler Particulate Matter for 24 hours period within the dry season (February -May 2016) which was associated with the heavily haze phenomenon in Malaysia. The distribution of selected toxic gases in UTHM student hostels was determined using the TSI IAQ (CO) and Dragger X-am 7000 (NO). PM10 and toxic gaseous levels were compared to the Ambient Air Quality Standard (AAQS) and to compute the assumption of the sources of PM10 by using Open Air R Package Software. Data were analysed using the R Software and packages (Open-air, BRT, Akima). The highest concentration of PM10 was 114 µg/m 3 recorded at KKTDI followed by 58 µg/m 3 at KKP. The maximum CO concentrations noted at KKP (1.8 ppm). However, both PM10 and CO concentrations not exceeded the AAQS of 150 µg/m 3 and 30 ppm respectively. Moreover, concentrations of NO at KKP (0.61 ppm) and KKM (2.18 ppm) exceeded the AAQS (0.17 ppm) indicating the possibility of presence health risk for students at UTHM due to poor air quality. The air quality is directly associated to level of energy consumption which causes climate changes and accumulation of greenhouse gases.

Monitoring of Outdoor and Indoor Air Particulate Matter (PM10) at Buildings Located in An Industrial District

“…Samuri, ( 2005) has recorded a PM10 concentration of 222.22 µg/m³ at the UTHM entrance which exceeded the recommended concentration at the Malaysian Ambient Air Quality Guidelines -2015 (RMAQ) and the National Ambient Air Quality Standards (NAAQS) (150 µg/m³ ). However, in 2016 R. Mohamed et al, (2017) have recorded moderated concentrations of PM10 at the UTHM university campus that ranged between 58 and 114 µg/m³ (<150 µg/m³). The indoor air quality of the UTHM university campus buildings was in accordance with the American Society of Heating, Refrigerating, and Air-Conditioning Engineers (ASHRAE), RMAQ, and NAAQS (R. Mohamed et al, 2017).…”

Mohamed et al, 2017). Among all the conducted studies, there was a lack of identifying the relationship between the inner and outer PM10 concentration in the UTHM campus buildings.…”

Examining Air Pollution Continuity in Tehran Province using Markov Chain Model

“…The challenges posed by outdoor air pollution are public health risks such as cardiovascular disease, respiratory ailments, COPD, and world-class asymmetry [2]. Air quality in the residential areas adjacent to the industrial regions is of great concern due to the association with particulate matter and toxic gaseous which has adverse effects on human health [3]. Considering the influence of air on human life and its consumption overnight, it can be stated that the unfavorable quality of air in today's world is considered one of the most important environmental problems in many of the world's large cities [4].…”
