Less Ozone Contamination By One Pesticide

posted on August 22, 2003

A cleanup in the ozone.

Government scientist say atmospheric levels of the pesticide methyl bromide have dropped 13% since 1998.

Methyl bromide -- formerly used to sterilize soils, grain silos and shipments of perishable goods -- breaks down in the air and releases bromine, which disperses into the stratosphere and attacks ozone molecules.

Environmentalists welcomed the report, but expressed concern the Bush administration is seeking exemptions to the pesticide ban for certain farm crops and golf-course owners.
