Pesticide Detection: Methyl Iodide and Methyl Bromide

Technology Benefits

Rapid detection at very low concentration of both pesticides Extremely sensitive No chemical analysis or laboratory required Easy to use Color indicates results Inexpensive

Technology Application

Detection of low level of fumigants in agricultural fields Other aerosol applications Organic or other certified agricultural practice verification

Detailed Technology Description

Researchers at the University of California, Davis have developed paper-based colorimetric sensors that can rapidly detect very low concentrations of methyl iodide and methyl bromide in air. The detection limit for methyl iodide and methyl bromide is 200 and 800 ppb, respectively. These sensors can be employed in agricultural fields and other aerosol applications to detect human exposure levels of either chemical.
