KUALA LUMPUR, July 1 — Hours after primary and secondary schools reopened in Pasir Gudang, Johor on Sunday, dozens of students have reportedly begun experiencing problems in breathing and having bouts of nausea.
They have been sent to the nearby Pasir Gudang and Masai health clinics.
Since last Tuesday, 475 educational facilities in the area were shuttered for three days due to air contamination.
The Department of Environment is continuing to monitor the surrounding air in Pasir Gudang.
Air quality readings are apparently normal allowing for classes to continue, including evening sessions.
The cause and source of the contaminants are still unknown.
Though not as serious as previous incidents, already more than 100 students from over 30 schools have been affected by this round of air pollution, which was first reported on June 20.
Science, Technology, Environment and Climate Change Minister Yeo Bee Yin announced last week that three types of flammable and toxic gases had been detected in the area.
