What does atrazine do to humans?
Maternal exposure to atrazine in drinking water has been associated with low fetal weight and heart, urinary, and limb defects in humans. Atrazine has been shown to slow down the development of fetuses in animals, and exposure to high levels of atrazine during pregnancy caused reduced survival of fetuses.
Where is atrazine banned?
Atrazine is banned in Europe, due to its potential to contaminate water sources, but widely used in the U.S., where about 70 million pounds of the pesticide is sprayed—mostly on corn, but also on sorghum, sugarcane, and a few other crops, as well as on golf courses, Christmas tree farms, and in residential landscaping.
How long does atrazine last?

Does Roundup contain atrazine?
Monsanto marketed its potent weed killer glyphosate—the active ingredient in Roundup—and the corn and soybeans genetically engineered to withstand it, by claiming it would replace other, more toxic weed killers such as atrazine. Glyphosate has become the most popular agricultural herbicide in the U.S. and globally.

Background/Aims: Atrazine (ATR) is a broad-spectrum herbicide in wide use around the world. However, ATR is neurotoxic and can cause cell death in dopaminergic neurons, leading to neurodegenerative disorders. Autophagy is the basic cellular catabolic process involving the degradation of proteins and damaged organelles.
How long does atrazine last in soil?
Atrazine has a low to moderate solubility in water. Atrazine does not bind well to soil and can easily move in it. It has an average half-life in soil of around 60-75 days.
How does Atrazine act to kill plants?
Atrazine kills plants by disrupting photosynthesis. Atrazine selectively kills non-desirable plants (weeds) that compete for water and nutrients with desirable plants (crops, turf- grass).
Is atrazine harmful to humans?
Health harms Human exposure to atrazine is linked to a number of serious health effects. A potent endocrine disrupter, atrazine interferes with hormonal activity of animals and humans at extremely low doses.
