摘要

A comprehensive study was undertaken to assess residual behaviour and dietary risk associated with a combination product containing trifloxystrobin and propineb in tomato, chilli and apple. Sample analysis was performed using validated QuEChERS method for trifloxystrobin and CGA 321113, while for propineb, method validated by Dubey and Stan (J Food Sci Technol 35:482–485, 1998) was used across all three crops, with residue detection using GC-ECD and UV–Vis spectrophotometer. Trifloxystrobin exhibited half-lives of 2.72–2.77 days in tomatoes, 2.49–2.89 days in chillies and 4.14–4.49 days in apples. Meanwhile, the half-life of propineb in tomatoes, chillies and apples were 1.27–1.51, 1.60–2.27 and 1.73–2.27 days, respectively. Upon comparing estimated daily intake (EDI) in India for both components of combination product with acceptable daily intake (ADI), the cumulative index of risk assessment and hazard index was consistently below 1 in all three crops, indicating no potential risk to consumers.
