| Abstract: | The method of residue analysis of enostrobilurin in water was established by HPLC detection after extraction using dichloromethane.The results indicated that fortified recoveries in water of this method were 98.1%~100.9% at 0.1 μg·mL-1 to 2 μg·mL-1 of fortification.The minimum detectable quantity in water was 2×10-9 g,and the minimum detectable concentration in water was 0.02 μg·mL-1.The Kow of enostrobilurin detected by bottle-shaking method in double-distilled water were 773.99~1 446.11,and lgKow was 3.03±0.12.The biological accumulation of enostrobilurin was high. |
