Quantifying TVOC and PM2.5 air pollution in Penang, Malaysia: A statistical analysis using HLW-100

Air pollution is one of the most significant issues addressed recently. The impact lies on public and individual health where illness and mortality found increased. There are numerous factors affect air quality, including current weather, especially wind and precipitation. The variations in air quality depends on regions (industrial or housing area) as well as day (morning or afternoon) and night (midnight) where it could be elevated. Particulate matter (PM) refers to particles with a varied but extremely small diameter, is one of the contaminants that can be breathed and enter our respiratory system. Above 55.5 µg/m

will induce impact to the respiratory system, including chronic obstructive pulmonary disease (COPD), asthma, and bronchiolitis. This research aims to measure and collect data on air quality (LW-100 Air Quality Monitoring Device) at Bayan Lepas and Perai, Penang Malaysia. The Statistical Package for the Social Sciences (SPSS) were used to show output data graph. The data will then compare with an open-source DOE data and collectively gathered. Both regions (Bayan Lepas and Perai) show significant results especially total volatile organic compound (TVOC) 3.8 mg/m

(haze), 0.6 mg/m

(normal days) and 0.3 mg/m

(raining days) respectively. Lastly, the presented data and analysis could benefit to local authorities to prevent industries from damaging the air quality.
