JOHOR BARU: All 111 primary and secondary schools in Pasir Gudang will remain open despite several students experiencing breathing difficulties and nausea on Sunday (June 30) morning.

State health, culture and heritage committee chairman Mohd Khuzzan Abu Bakar said that classes would go continue as air quality readings here were normal.

"We will move students whose classrooms are at higher floor to a lower level as most students who experienced symptoms today are from the third and fourth floors.

He said agencies like the Pasir Gudang Emergency Mutual Aid (Pagema) and the Department of Enviroment (DoE) would continue to monitor the air around Pasir Gudang.

He added that some 130 students, including three teachers from 15 schools, experienced symptoms on Sunday (June 30).

"About 30 were sent to the Pasir Gudang and Masai health clinics," he said at SK Kopok, one of the affected schools here.

He added that schools with evening sessions, including SK Kopok, would continue classes as usual Sunday.

It was earlier reported that several students from various schools had experienced breathing difficulties just hours after schools in Pasir Gudang reopened.
