Dear Mr. Helliker,
I thought you might like to read EPA's REVISED POLICY ISSUED ON USE OF
CHOLINESTERASE INHIBITION DATA IN PESTICIDE RISK ASSESSMENTS - (Press Advisory
9/7/00).
EPA this week announced the availability of the revised
science policy paper, "The Use of Data on Cholinesterase Inhibition for
Risk Assessments of Organophosphorus and Carbamate Pesticides."
The policy clarifies the Agency's position that the inhibition of
acetylcholinesterase by organophosphate and carbamate pesticides is the key
event in causing harmful effects on nervous system function and outlines how EPA
will consider various types of data in determining safe levels of exposure.
Cholinesterase is an important enzyme that regulates levels of
acetylcholine in the nervous system. Inhibition
of cholinesterase can cause effects that increase in severity as the dose of the
cholinesterase inhibitor increases. These effects can range from muscle tremors
to various neurological effects to death. The
revised paper is available at: http://www.epa.gov/trac/science.
The Federal Register notice announcing the availability of this document
is expected to be published Sept. 8.
Well Mr. Helliker, this revised policy comes a little
too late for many innocent victims of your "registered" POISONS.
When will you begin to consider the Precautionary Principle BEFORE you
"register" these terrible toxins. Especially when there are so may
safe, and far more effective unregistered alternatives - but, I forgot - none of
these food grade and/or GRAS materials are "legal" (in your opinion)
for professional pest control use in California.
So, there obviously must be more innocent victims.
