Porphyria patients always need to be careful of exposure to
herbicides, pesticides and fungicides. DDT and marathion have
long been known as hazards to avoid. Another chemical compound to
avoid is that of Methyl bromide.
Methyl bromide is a potent nerve toxin that is extremely
dangerous to people and the environment. EPA classifies it as a
Toxicity Category I toxin.
In addition Methyl bromide has caused birth defects and damage to
the brain and the CNS [central nervous system] in studies
performed on laboratory animals.
Methyl bromide also depletes the Earth's protective ozone layer.
This substance is now scheduled to be phased out in
industrialized countries in 2005. But of course the harmful
substance will still pose a threat to Third World nations. Methyl
bromide is widely used across California and other parts of the
west to grow strawberries, grapes and other crops. In past years
California used nearly 14 million pounds of methyl bromide,
making it one of the largest methyl bromide-using regions in the
world. The product is used by fumigation application. Therefore
porphyria patients living near or in these areas need to exercise
extreme caution.
Methyl bromide can drift more than 300 feet from fumigation sites
: To protect farmworkers working near fumigated fields scientists
have shown that there should be a buffer zone at least 190 feet
to adequately protect workers from short-term exposure of methyl
bromide.
Under an upcoming international ozone protection treaty, methyl
bromide use in the United States and other industrialized
countries will be reduced by 50% in 2001, 70% in 2003 and fully
banned in 2005. .
In years past the wide spread use of DDT, chlordane and malathion
caused a wide array of health problems. The current list of
chemical toxins that are used widely which can trigger porphyria
attacks keeps on growing.
As a porphyria patient you must become acutely aware of the
potential damaging chemical toxins that you may be exposed to.
