The Pollution Control Department (PCD) has warned residents of Bangkok and several neighboring provinces about worsening air quality in the coming days.

According to experts' forecasts, the level of PM2.5 air particle pollution will rise to a dangerously orange level from Friday through Sunday.

Poor air quality is attributed to reduced precipitation and a cold front, which could lead to poor air circulation and the accumulation of PM2.5 dust in the atmosphere.

Residents of Bangkok, Samut Prakan, Samut Sakhon, Nakhon Pathom, Pathum Thani, and Nonthaburi are advised to monitor air quality, reduce outdoor activities, and wear protective masks when needed.

Anyone experiencing symptoms such as coughing, difficulty breathing, eye irritation, chest tightness, headache, palpitations, nausea, or fatigue is advised to seek medical attention.
