High-purity reference materials for accurate and reliable residue analysis

Overview

Atrazine is a chlorinated herbicide belonging to the triazine class. Its IUPAC name is 6-Chloro-N2-ethyl-N4-(propan-2-yl)-1,3,5-triazine-2,4-diamine. Atrazine is primarily used to prevent pre-emergence broadleaf weeds in crops such as maize, soybean, and sugarcane, as well as on turf like golf courses and residential lawns. It is one of the most widely used herbicides in the United States, Canada, and Australia.

Uses

Atrazine is used to control broadleaf and grassy weeds in crops such as sorghum, maize, sugarcane, lupins, pine, and eucalypt plantations, and triazine-tolerant canola. It is the second-most widely used herbicide in the United States after glyphosate, with 76 million pounds applied annually. Atrazine treatments have been shown to increase corn yields by an average of 5.7 bushels per acre compared to alternative herbicide treatments.

Regulatory

Atrazine's use was banned in the European Union in 2004 due to groundwater contamination concerns. In the United States, the EPA has conducted multiple reviews, concluding that atrazine does not pose a significant risk to human health when used according to regulations. However, its safety remains controversial, and the EPA continues to monitor and review its use.

Monitoring

Atrazine contamination of surface water in the U.S. has been consistently monitored by the EPA, with levels often exceeding regulatory limits in certain watersheds. Monitoring of community water systems in high-use states found that atrazine levels exceeded concern thresholds for infant exposure in some cases.

Health Impact

Atrazine is considered an endocrine disruptor, potentially affecting the hormonal system in humans and animals. Studies have linked atrazine exposure to reproductive issues, such as preterm delivery and birth defects. However, the EPA has stated that current regulations ensure that exposure levels do not pose significant reproductive risks to humans.

Environmental Impact

Atrazine can persist in soil for months and migrate to groundwater, where it degrades slowly. It has been detected in groundwater at high levels in regions where it is heavily used. Atrazine biodegrades primarily through microbial action, with a half-life ranging from 13 to 261 days. Photolytic degradation using UV light has also been studied as a potential method for reducing atrazine contamination.

Safety Measures

The EPA has set a maximum contaminant level for atrazine in drinking water at 0.003 mg/L. The recommended exposure limit (REL) for atrazine is 5 mg/m³ as a time-weighted average (TWA). Proper handling and application practices are essential to minimize exposure and environmental contamination.
