Abstract EN
Herein, we present a method for the quantitative analysis of broflanilide residues in water, soil, and rice samples from a paddy field in Jiangxi Province, China.
The quick, easy, cheap, effective, rugged, and safe (QuEChERS) method was optimized for the extraction and purification of broflanilide residues.
Residual broflanilide concentrations in different matrices were then determined by high-performance liquid chromatography (HPLC).
The calibration curve of broflanilide showed good linearity in all matrices for concentrations between 0.005 and 1 mg·L−1, with a correlation coefficient greater than 0.99.
The matrix effect varied from −69% to −54%, indicating matrix suppression.
The average recoveries ranged between 85.82% and 97.46%, with relative standard deviations of 3.29%–8.15%.
The limits of detection ranged from 0.16 to 1.67 μg·kg−1, and the limits of quantification were in the range of 0.54 to 5.48 μg·kg−1.
Dissipation dynamic tests indicated broflanilide half-lives of 0.46–2.46, 2.09–5.34, and 1.31–3.32 days in soil, water, and rice straw, respectively.
Broflanilide was dissipated more rapidly in water than in soil and rice straw.
More than 90% of broflanilide residues dissipated within 14 days.
The final residues of broflanilide in rice were all below LOQ at harvest.
