Atrizine is one of the
most common contaminants found in our drinking water. It is an herbicide used to control weeds, used extensively on large crops such as corn and sugar cane. It is used on golf courses christmas tree farms and in regrowing forests. This herbicide works by
interfering with photosynthesis, it moves upward into new areas of growth by being taken up
through the roots and leaves.
In the farming industry it is considered innovative, but in the bodies of living beings it can be harmful, deadly or life altering. Many studies have shown these negative affects. It is a hormone disruptor. it harms reproductive health in both men and women,
it is carcinogenic. It can
cause birth defects, harm fetal development and survival. In animal studies it has been found to harm the heart and liver and is thought that it could also have the same effect in humans but hasn’t been studied. It has also
been found to cause type 2 diabetes insulin resistance and caridomyopathy & oxidative stress. In
another study it was shown to alter dopamine levels leading to neurodegenerative disorders. It caused the release of inflammatory cytokines and neurotoxic substances leading to neurodegeneration. In a study exposing
crayfish to the herbicide they displayed behavioral changes leading to a negative impact on their ability to survive such as finding a mate or food.
In 1997 Syngenta asked Tyrone Hayes of University of California Berkeley to study their product Atrizine.
What he found was that is was a hormone disruptor, in laboratory tests a small amount of the chemical caused frogs to become chemically castrated and eventually change sex. When he brought his research to them, they told him he wasn’t allowed to publish it or talk about it with other scientists. They asked him to manipulate the data. He refused, they went so far as to threaten his life and the safety of his family members.
The use of Atrazine is
banned in 60 countries. Many have called for it to be banned in the US. The EPA has
proposed changes to how this herbicide is used in order to protect aquatic plant communities. The changes proposed will limit the amount that can be used as well as
how and when it is applied to lessen the impact from runoff. By no means are these new proposed rules predicted to slow down the use of this herbicide. The
market is expected to grow significantly in the coming years with
no slowing down in sight. The proposed rule changes seem to be geared toward plant life, rather than the affects on human and animal health. The drinking water limits for Atrizine remain
unchanged at 3ppb. However levels much lower than that
have shown to be harmful.
