A lorry is believed to have dumped the waste in southern Johor state last week, sending hazardous fumes across a wide area and causing those affected to display symptoms of poisoning such as nausea and vomiting.
"The ministry of education has decided to close all 111 schools in the Pasir Gudang area immediately," he said in a statement.
"The education ministry is requesting that all parties take precautions."
Three men were arrested earlier this week over the toxic waste dumping. One is expected to be charged in court soon and could face up to five years in jail if found guilty of breaking environmental protection laws.
