KUALA LUMPUR: Rainfall has helped clean the air in the Klang Valley, but Sri Aman in Sarawak has recorded an unhealthy Air Pollution Index (API) as of 10am today.
A check on the Department of Environment's (DoE) Air Pollutant Index Management System (APIMS) website shows that Sri Aman has the highest reading across the nation, at 121.
APIMS measures the API readings between 0 and 50 as good, 51 and 100 as moderate, 101 to 200 as unhealthy, 201 to 300 as very unhealthy and any readings of 300 and above are declared as hazardous.
Cheras, which recorded API readings breaching the 150 mark for over 24 hours, shifted to a moderate level at 4am.
The hazy condition in Nilai has also transitioned to a moderate level at 2am.
Yesterday morning, seven locations across the country recorded unhealthy API readings exceeding 100, mainly in the Klang Valley and Seremban areas.
DoE director-general Datuk Wan Abdul Latiff Wan Jaafar previously said the National Disaster Management Agency (Nadma) would activate the Disaster Management Committee at the district, state, or central level when the API reading exceeded 150 for a period of more than 24 hours.
He said, however, that cloud seeding could only be carried out if clouds were present and conditions were favourable.
Education Minister Fadhlina Sidek yesterday said that if the API reading in any given area reached 200, all schools in the area would immediately be closed and adopt the home-based teaching and learning method (PdPR).
Out-of-classroom activities are halted for areas with the API reading breaching 100.
