US Stockpiles Banned
Pesticide
The internationally banned pesticide Methyl Bromide, which
is the most powerful ozone-depleting substance currently
used in large scale, is still being produced in the US
despite massive stockpiles. Over the past two years, millions
of pounds have been produced, and when added to stockpiled
amounts, total almost twice as much as US farmers actually
use each year. Under a loophole in the international treaty,
Methyl Bromide is permitted for so-called “critical
uses”
- such as strawberry and tomato production - by the EPA.

Pollinator
Population Plummets
A study released by the National Research Council
show that populations of important pollinators, such
as birds, bees and bats, are on the decline in the
US and around the world. This could mean severe damage
and depletion of crops. American honeybee populations
have dropped 30% in the past 20 years. According
to Gene Robinson, an entomologist at the University
of Illinois, US farmers had to import honeybees last
year for the first time since 1922. The pollinators
are disappearing due to a combination of factors
including parasites, pesticides and loss of habitat
from development.

WHO Endorses
DDT Use
Though outdoor spraying of DDT was banned in the
early 1970s, the World Health Organization is endorsing
indoor spraying to combat the spread of malaria in
some developing African countries. Researchers at
a recent American Chemical Society meeting presented
data that showed exposure to DDT can contribute to
the onset of Parkinson's Disease, and may slow or
stunt development of infants exposed in the womb.
Some former anti-DDT activists, such as Environmental
Defense, support the WHO decision. However, Washington
D.C.-based Beyond Pesticides warns, "it will
poison future generations."

Daycare
Centers Test Positive for Pesticides
As more and more daycare centers across the country
are notifying parents and reducing pesticide use,
scientists have released the first nationwide study
of residual insecticides in such centers, published
in the October 2006 issue of Environmental Science & Technology.
Organophosphate and pyrethroid pesticides were found
in low levels throughout all of the 168 US daycare
centers tested, with the highest levels found in
centers in the South. The EPA National Exposure Research
Laboratory took samples swiped from floors and tables,
and also took soil samples from outdoor play areas.
The health impacts from the study are unclear. But
Lynn Goldman, professor of applied health at Johns
Hopkins University and former head of the EPA's Pesticide
Program, stated simply
"These chemicals should be avoided around children."
