NAFDAC, in a statement by its Director-General, Prof. Mojisola Adeyeye, said methyl bromide is a class I ozone, which depletes substance (ODS). It depletes the ozone layer due to the release of bromine atom upon the break down of the molecule. Methyl bromide is also a scheduled chemical under the Montreal protocol for substances that deplete the ozone layer and was placed on a phase-out procedure from 2001. Nigeria effected the phase-out of methyl bromide by January 2015 and since then, the product has not been permitted for importation, NADFAC warned.
“Methyl bromide is an extremely toxic vapour. In humans, methyl bromide is readily absorbed through the lungs. Most problems occur as a result of inhalation. Methyl bromide is a dangerous cumulative poison. First symptoms often are due to damage to the nervous system, and may be delayed from 48 hours to, as long as several month...
