Atrazine is a herbicide of the triazine class. It is the most widely used herbicide in the United States and one of the most widely used herbicides in Australian agriculture. It was banned in the European Union in 2004. Atrazine is used to prevent pre and post-emergence broadleaf weeds in crops such as maize (corn) and sugarcane and on turf, such as golf courses and residential lawns.
Atrazine is the most commonly detected contaminant of drinking water in the United States. It is a potential endocrine disruptor, an agent that may alter the natural hormonal system in animals. In 2006 the U.S. Environmental Protection Agency (EPA) stated that "the risks associated with the pesticide residues pose a reasonable certainty of no harm", and in 2007 the EPA said that atrazine does not adversely affect amphibian sexual development and that no additional testing was warranted. However, in 2009 the EPA began a new scientific evaluation of health effects on atrazine. Numerous studies have stated that atrazine has substantial adverse reproductive effects even at levels said by the EPA to be safe.
