Methyl Bromide Leaves Residents Fuming

The Montreal Protocol on Substances that Deplete the Ozone Layer has proven to be a resounding environmental success, halting and then reversing the depletion of stratospheric ozone caused by man-made halogenated compounds.  Although global efforts initially focused on long-lived chlorofluorocarbons (CFCs), as their atmospheric levels have begun to decline it is emerging that "short-lived" ozone depleting substances with atmospheric lifetimes of months to years are playing an increasingly significant role, and they are also proving more of a challenge to eradicate.
The atmospheric chemistry of short lived ozone depleting substances is an area of research I'm currently working on, so I was intrigued to see one of these compounds - methyl bromide - in the news this week.  A proposal to build a large methyl bromide fumigation facility to treat logs in the North Carolina town of Delco has been met with anger from locals, who are concerned about potential health and environm…
