I was in the army and knew a good deal more about the effects of potassium bromide
than most people.
Is Bacillus thuringiensis a good surrogate for Bacillus anthracis during methyl bromide
Specifically, they want CUEs to be granted for more than one year and production levels to be frozen at 30 percent of the 1995-1998 baseline production while scientists (both government and private sector) evaluate the impact of methyl bromide
on the ozone layer and search for an alternative.
Also in our suit is that the EPA has allowed the big bromide
companies to keep producing even though we found that the U.
They found in this case that the VIF retained more active compounds for a longer period of time than with methyl bromide
Although methyl bromide
was not proscribed in the original text of the Montreal Protocol with chlorofluorocarbons and halons, policy-makers recognized a decade later that it was a powerful ozone-depleting chemical that had destroyed as much as 4% of the planet's ozone layer over the previous two decades.
Their mechanism of action is thought to be due to the close resemblance of the bromide
ion to chloride.
occurs naturally at low levels in food.
As the soil profile contains a significant amount of allophane, to which bromide
can adsorb, the levels of allophane in the profile were used instead of organic carbon for the bromide
Half the bromine that makes its way into the upper layers of the atmosphere comes from methyl bromide
, says Stephen A.
Table 2 shows the distribution of methyl bromide
use for each trimester for the buffer distance of interest (5 km) and the three additional buffer distances used in sensitivity analyses (1, 3, and 8 km).
Prolonged exposure to methyl bromide
has also been linked to comas and death, according to the IRET and various international health organizations.
The compounds are hexachlorobutadiene (a solvent used to make vinyl chloride), n-propyl bromide
(a solvent that is used in pharmaceutical production), 6-bromo-2-methoxyl-napthalene (used to make the fumigant, methyl bromide
) and halon-1202 (used in fire extinguishers).
On July 19 2001, the Environmental Protection Agency (EPA) issued interim final rules to create a temporary exemption through December 2002 for the consumption and production of methyl bromide
for quarantine and preshipment uses.
While good for crops, methyl bromide
is harmful to the atmospheric ozone layer.
