Abstract

Nestled in the heart of urbanization, the Klang Valley faces a vital concern, grappling with the pressing issue of air quality degradation. PM₁₀, the ubiquitous pollutant, looms large as the primary pollutant behind the city's smog-filled skies, calling for urgent attention and effective solutions to ensure a sustainable and breathable future for all its inhabitants. This study aimed to assess the seasonal distribution of PM₁₀ concentration in a specific area within Klang Valley, Malaysia, using the spatial deterministic interpolation method known as Inverse Distance Weight (IDW). 768 data from eight air quality monitoring stations in Klang Valley were used which considered PM₁₀ concentrations and meteorological parameters (humidity, temperature and wind speed) in 2015 and 2016. This study found that, Kuala Selangor, a suburban area, had the best air quality (42.8 µg/m³ in 2015; 42.42 µg/m³ in 2016) in both years as it had the lowest population. Meanwhile, Shah Alam (an urban area) was recorded as the area with the highest PM₁₀ concentration (426.6 µg/m³) at the hazardous level, particularly during the haze episodes. The seasonal spatial interpolation analysis indicated that the period with the least air pollution occurs during the northeast monsoon (from 42.42 to 127.1 µg/m³). The only significant correlation was analysed between humidity and PM₁₀ concentration during northeast monsoon (R-value = -0.324) and spring inter-monsoon (R-value = 0.528) respectively. Overall, the pollutant distribution in Klang Valley vary depending on the seasons, influenced by factors such as population density, land use and land cover (LULC), transboundary haze, the natural environment, and local meteorological conditions.
