Findings

Congress finds the following: (1)The United States annually uses 60,000,000 to 80,000,000 pounds of atrazine, a weed-killing pesticide. (2)The toxicity of atrazine is well documented and has shown to have adverse endocrine effects in amphibians, mammals, and humans. There is evidence that atrazine exposure is associated with low sperm counts and poor motility in exposed adult men, and that prebirth atrazine exposure is associated with small birth weight and abnormal development of the gut wall in infants. In laboratory mammals, exposure is associated with abnormal reproductive system development, impaired prostate gland formation, and abnormal breast tissue development. In aquatic wildlife, exposure is associated with abnormal reproductive system development, impaired reproduction, and impaired immune system function. (3)The United States Fish and Wildlife Service acknowledges that atrazine may have potential adverse effects on fish, such as organ tissue disease, disruption to the endocrine and olfactory systems, and reduced reproductive function. (4)The United States Geological Survey found atrazine in approximately 75 percent of stream waters and 40 percent of all ground water samples from agricultural areas tested. According to data from the Environmental Protection Agency Ecological Watershed Monitoring Program, the surface water sampled in the Midwestern and Southern United States suffers from pervasive atrazine contamination. Sampling of watersheds between 2004 and 2006 showed that all 40 watersheds tested had detectable levels of atrazine and 25 watersheds had average concentrations above 1 ppb. While these average elevated concentrations of atrazine are worrisome, high peak concentrations may also be dangerous. Nine watersheds had at least one sample showing levels above 50 ppb, and four watersheds had levels above 100 ppb. (5)According to data from the Environmental Protection Agency Atrazine Monitoring Program, high levels of atrazine are also evident in drinking water systems. More than 90 percent of the samples taken in 139 water systems had measurable levels of atrazine in both 2003 and 2004. Three systems had annual averages exceeding 3 ppb. (6)In 1991, Germany and Italy banned the use of atrazine. In 2003, European regulators announced a ban on the pesticide throughout the European Union. (7)The Department of Agriculture estimates that a ban on atrazine would result in crop losses of only 1.19 percent and decrease corn acreage by only 2.3 percent. Since banning atrazine nearly 20 years ago, both Italy and Germany have not experienced a reduction of corn productivity or total acreage of land in production.
