This study aims to assess and compare levels of particulate matter(PM10 and PM2.5)in urban and industrial areas in Malaysia during haze episodes,which typically occur in the south west monsoon *** high concentrations of atmospheric particles are mainly due to pollution from neighbouring *** PM concentrations were analysed for urban and industrial areas including Alor Setar,Tasek,Shah Alam,Klang,Bandaraya Melaka,Larkin,Balok Baru,and Kuala Terengganu in 2018 and *** analysis employed spatiotemporal to examine how PM levels were *** data summary revealed that PM levels in all study areas were right-skewed,indicating the occurrence of high particulate *** peaks in PM concentrations during haze events were consistently observed between June and October,encompassing the south west monsoon and inter-monsoon *** study on acute respiratory illnesses primarily focused on *** revealed that Klang had the highest mean number of inpatient cases for acute exacerbation of bronchial asthma(AEBA)and acute exacerbation of chronic obstructive pulmonary disease(AECOPD)with values of 260.500 and 185.170,***,for outpatient cases of AEBA and AECOPD,Klang had the highest average values of 41.67 and 14.00,*** Alam and Sungai Buloh did not show a significant increase in cases during periods of biomass *** statistical analysis concluded that higher concentrations of PM were associated with increased hospital admissions,particularly from June to September,as shown in the bar *** episodes were associated with more healthcare utilization due to haze-related respiratory illnesses,seen in higher inpatient and outpatient visits(p<0.05).However,seasonal variability had minimal impact on healthcare *** findings offer a comprehensive assessment of PM levels during historic haze episodes,providing valuable insights for authorities to develop policies and guidelines fo
