Method development and validation for boscalid in blueberries by solid-phase microextraction gas chromatography, and their degradation kinetics

► We developed an SPME-GC method for determination of boscalid in blueberries. ► The method validated was accurate, efficient and precise. ► We studied the effect of pH and fiber coating. ► The degradation of boscalid followed a first order rate kinetics. ► Half-life for boscalid was 5.3 and 6.3 days for Emerald and Jewel cultivars.
