The Ogun State government has dismissed traditional explanations surrounding recurring gas emissions in Ijebu-Ode communities.
It described the incidents as natural underground geological events linked to fault lines.
The state Commissioner for Environment, Dr. Ola Oresanya, made the disclosure during a town hall meeting in Ijebu-Ode on Sunday.
Recall that students and teachers were hospitalised after suspected chemical odour exposure.
The incidents occurred on three occasions this year across some schools in Ijebu-Ode.
Oresanya said investigations revealed methane and sulphide gases were responsible for the emissions.
He explained that the gases escaped through underground fractures along established fault lines.
“The occurrence is not traditional mythology but a natural geological process,” Oresanya said.
He identified the Ifewara-Zungeru trans-Atlantic fault line as a major factor behind the incidents.
The commissioner said the fault line stretched from Mojoda through Ijebu-Ode to Osun.
According to him, affected schools are located along the identified geological corridor.
Oresanya said the area was historically forested and largely uninhabited before missionary settlements.
He suggested that deserted lands were allocated to missionaries, leading to the establishment of schools there.
The commissioner said further laboratory studies would determine the exact origin of the gases.
He noted that researchers were examining whether the gases were thermogenic or methanogenic, adding that government was investigating possible natural gas deposits beneath the communities.
Meanwhile, the state Commissioner for Health, Dr. Tomi Coker, urged residents to remain calm.
