Glyphosate Factsheet

Journal of Pesticide Reform

Glyphosate herbicides (one common brand name is Roundup) are the mostly commonly used herbicides in the U.S.
and the world. In agriculture they are widely used with genetically-modified glyphosate-tolerant crops, but they are
also widely used in yards, gardens, and other nonagricultural areas.Symptoms of exposure to glyphosate include eye irritation,
burning eyes, blurred vision, skin rashes, burning or itchy skin, nausea, sore throat, asthma and difficulty breathing, headache,
lethargy, nose bleeds, and dizziness.
Glyphosate and glyphosate-containing herbicides caused genetic damage in laboratory tests with human cells, as
well as in tests with laboratory animals. Studies of farmers and other people exposed to glyphosate herbicides have shown
that this exposure is linked with increased risks of the cancer non-Hodgkin’s lymphoma, miscarriages, and attention deficit disorder.
For each of thehazards identified in these studies there are also laboratory studies with results that are consistent with the studies
of exposed people.
There is also laboratory evidence that glyphosate herbicides can reduce production of sex hormones.
Studies of glyphosate contamination of water are limited, but new results indicate that it can commonly
contaminate streams in both agricultural and urban areas.
Problems with drift of glyphosate herbicides occur frequently. Only one other herbicide causes more drift incidents.
Glyphosate herbicides caused genetic damage and damage to the immune system in fish. In frogs, glyphosate
herbicides caused genetic damage and abnormal development.
Application of glyphosate herbicides increases the severity of a variety of plant diseases.
