Efficiency of Magnetically Treated Water on Decontamination of Chlorpyrifos® Residual: A Practically Water Insoluble Organophosphate in Brassica chinensis Linn.

Chlorpyrifos® (Thaion Agro Chemical CO., Ltd. Yannawa, Bangkok 10120, Thailand) (an almost water insoluble organophosphate insecticide) has been extensively used, resulting in the presence as a surface contaminant foodstuffs, streams and soils. It is thus critically essential to develop methods degrade or remove eliminate this pollutant from environments. very limited solubility so it primarily of surfaces foodstuffs. We present effect magnetically treated (MTW) contaminating Brassica chinensis Linn., commonly eaten vegetable Thailand globally. Samples were washed with prior detection GC-MS (Gas Chromatograph-Mass Spectroscopy). was removed by factor 413 times (−99.7%) MTW compared un-washed sample, whereas removal for tap washing only 9.6 (−89%). The material easily passed safety criteria (Maximum Residue Load—MRL), but vegetables did not do reliably. Although may be banned many countries, binding properties replacement organophosphates are likely similar, our results should generalize pesticides chemical class that readily soluble.
