Air quality deteriorated significantly across Malaysia, with the Air Pollutant Index (API) reaching unhealthy thresholds in 28 areas as of September 17, according to monitoring data released in Kuala Lumpur. Perak emerged as the worst-affected state, recording multiple locations with hazardous pollution levels that pose risks to public health.

The widespread API readings classified as unhealthy trigger health advisories for vulnerable populations, including children, elderly residents, and those with respiratory conditions. Authorities typically recommend that at-risk groups limit outdoor activities when API levels breach the unhealthy threshold.

The spike in air pollution levels across the peninsula reflects seasonal patterns and transboundary haze issues that frequently affect Malaysia during certain months. Environmental authorities continue to monitor conditions closely and advise residents in affected areas to check real-time API updates before planning outdoor activities.

Residents in areas experiencing unhealthy air quality are encouraged to wear N95 masks when venturing outdoors and to keep indoor air clean through proper ventilation and air purification measures. Health officials recommend staying updated on air quality forecasts through official government channels.
