General description
Bromomethane solution (methyl bromide) is the most effective soil fumigant for killing plant pests, its use is being phased out because its emissions from soil can lead to stratospheric ozone depletion[1]. The bimolecular nucleophilic substitution (SN2) reaction of methyl bromide and OH- in aqueous solution has been investigated using a multilayered-representation quantum mechanical and molecular mechanics methodology[2].
Packaging
Supplied in a Sure/Pac™ cylinder and has a 1/4-turn bronze ball valve with a female 1/4" NPT outlet thread (Z122661) installed. Before using the cylinder, ensure that the valve is closed, then remove carbon steel plug that seals the outlet valve.
Compatible with the following:

Despite generally being considered the most effective soil fumigant, methyl bromide (MeBr) use is being phased out because its emissions from soil can lead to stratospheric ozone depletion. However, a large amount is still currently used due to Critical Use

Manganese (Mn) is an essential nutrient with potential neurotoxic effects. Mn deposited in the nose is apparently transported to the brain through anterograde axonal transport, bypassing the blood-brain barrier. However, the role of the olfactory epithelial cells in Mn transport
