Mrs Iyabo Fakunle-Okieimen, the state Commissioner for Environment and Natural Resources, said this in a statement issued in Ado Ekiti on Sunday.
Fakunle-Okieimen said that conducting the test was crucial to achieving the goal of reducing air pollutants emitted from the exhaust systems of petrol and diesel engines to a tolerable level.
Quoting the World Health Organisation (WHO), the commissioner noted that harmful emissions from exhausts of engines were major contributory factors to poor air quality.
She named such diseases to include lower respiratory infections, tuberculosis, cancers, cerebrovascular and ischaemic heart diseases.
The commissioner explained that these emissions also depleted the ozone layer, allowing the direct radiation of the sun on earth, thus making the environment to experience unnecessary heat.
Fakunle-Okieimen said government would need the support of all stakeholders in ensuring the well-being of the people, just as she assured that officials for the test had been directed to be thorough and professional. (NAN)
