The stations with very unhealthy air quality were Port Dickson in Negeri Sembilan (207), Kuching in Sarawak (216) and Johan Setia in Klang, Selangor (232).
An API reading of between zero to 50 indicates good air quality; 51 to 100, moderate; 101 to 200, unhealthy; 201 to 300, very unhealthy and 300 and above, hazardous.
A total of 531 schools, involving 363,991 students, were closed today, with 145 of the schools in Selangor, Sarawak (298), Negeri Sembilan (63) and Putrajaya (25).

For those driving in areas with API of more than 300, like Sri Aman, it said, they should switch on the headlamps of their vehicles.
