摘要

AbstractA small‐scale method for the determination of pyrethroid insecticide residues in crops and soils is described. Compared with the conventional methods, the overall analysis time is reduced by approximately 60 and solvent usage is reduced by approximately 80 using this approach. Results obtained on a range of crops using the small‐scale and conventional methods were in good agreement, and a repeatability study showed that the small‐scale approach is unbiased and gives good precision. To date, linseed, tobacco, cotton foliage, cotton seed, wheat grain, sorghum, savoy, cauliflower, cabbage, cucumber, apple, peach, blackcurrant, gooseberry, raspberry and soil samples have been analysed using the method. Good recoveries were obtained with all these mat
