  Photodegradation of Pesticides. Photolysis Rates and Half-Life of Pirimicarb and Its Metabolites in Reactions in Water and in Solid Phase

  摘要：

  The photodegradation of Pirimicarb under three different artificial lights and sunlight was studied in water solutions (buffers pH 5, 6, and 7) and in solid phase. Five photocompounds were formed in solution and two in solid phase. Pirimicarb undergoes fast degradation under all conditions. In buffer solutions it first gave three compounds with a kinetic parallel process. These compounds were assigned the structures of 2-[(methylformyl)amino]-5,6-dimethylpyrimidin-4-yl dimethylcarbamate (II), 2-(methylamino)-5,6-dimethylpyrimidin-4-yl dimethylcarbamate (III), and 2-(dimethylamino)-5,6-dimethyl-4-hydroxypyrimidine (V). V and II were stable to further photolysis (the latter with t(1/2) = 849 h) where as III undergoes further degradation to 2-amino-5,6-dimethylpyrimidin-4-yl dimethylcarbamate (IV), and to 2-(formylamino)-5,6-dimethylpyrimidin-4-yl dimethylcarbamate (IX). Both compounds were photodegraded to undetectable species, and IX shows a very high t(1/2) (48 h). A different behavior was found in solid phase, and only II and III were formed. A kinetic parallel process was demonstrated. The environmental t(1/2) and t(1/100) calculated for Pirimicarb and its photoproducts suggest their reduced persistence in natural waters.
