Particulate dust up to 10 microns (PM10) was detected at between 65 - 153 mg / m3 exceeding standard in the central area of Nakhon Pathom and Samut Sakhon.

The department warned people to monitor their health. Anyone suffering such symptoms as coughing, difficulty breathing or eye irritation should reduce the duration of outdoor activities or wear protective masks.
