Petaling Jaya among 30 areas hit by unhealthy air quality

Air quality deteriorated across Malaysia on Wednesday, with three dozen areas recording unhealthy pollution levels as of 9am. Petaling Jaya in Selangor was among the affected zones, registering an API of 149, which falls within the unhealthy category. The reading prompted health advisories for vulnerable groups including children, the elderly, and those with respiratory conditions. Serian in Sarawak emerged as the worst-affected location nationally, posting an API reading of 180. The elevated pollution levels across multiple regions suggest widespread air quality concerns, though the contributing factors were not immediately specified. Authorities typically issue health warnings when API readings exceed 100, recommending residents in affected areas limit outdoor activities and use protective masks when necessary. The situation underscores ongoing challenges with air quality management in the region, particularly during certain seasons when atmospheric conditions trap pollutants.
