Impact of trace elements on stability and detoxification of imazethapyr herbicide in water and milk

Imazethapyr is a herbicide belongs to the class of imidazolinone herbicides. Exposure to Imazethapyr (IM) causes residues in body and biological systems. This study was carried out to evaluate the stability of imazethapyr in different chemical & physical conditions such as temperature, ionic strength, pH, presence of metallic ions (Ag+, Cu+2, Na+, Mg+2) in water and milk matrix to predict the factors can diminish Imazethapyr (IM) toxicity in biological systems and environment. Monitoring of imazethapyr was performed using liquid chromatography systems. The results were shown that temperature and pH and the (Ag+, Na+, Mg+2) ions have no effect on stability degradation or interaction of imazethapyr. Only copper ions (Cu+2) showed selective interaction with imazethapyr and form complex with imazethapyr. This study revealed Cu+2 ions have effect through stabilisation of imazethapyr by complexation. This process can use for detoxification of imazethapyr and Cu+2 in environment and biological systems.
