Development of a microparticle-based on-site immunoassay for the detection of atrazine in soil and water samples

Abstract

Atrazine is widely used as a herbicide in agriculture and has been identified as a major groundwater contaminant in the US. Because of the possible hazard associated with its usage, there is a need for an efficient and economic screening method for on-site field testing of atrazine and other s-triazine herbicides in soil and water. We have developed a rapid, on-site test for the detection of atrazine based on the principle of microparticle agglutination inhibition immunoassay. The test detects 50 µg kg−1 (0.050 ppm) atrazine in soil samples with direct extraction and 1.0 µg L−1 atrazine in water samples when coupled with solid phase extraction.
