摘要

Pentachlorophenol (PCP) is a persistent organic pollutant that bioaccumulates in animal tissues, posing a significant food safety concern in meat products. Effective monitoring of PCP residue in these meat matrices is crucial for protecting consumer health and ensuring regulatory compliance. This study demonstrates a novel fast pesticide extraction cum semi-automated in-syringe assisted cleanup (FaPEx-SA-ISAC) technique coupled with LC–MS/MS for rapid and efficient quantification of pentachlorophenol (PCP) in livestock and poultry meats. Various method parameters were examined and optimized to achieve maximum sensitivity in the detection of PCP in meat matrices. Based on optimal conditions, the validated method exhibited excellent linearity (R2 > 0.999) in the concentration range between 0.05 ~ 20 ng/g with limits of detection (0.01 ng/g for chicken meat, and 0.02 ng/g for pork meat) and quantification (0.05 ng/g for both chicken and pork meat). The developed method was applied to evaluate different meat matrices, including pork and chicken samples, and yielded satisfactory recoveries ranging from 88.6% to 111.1% and relative standard deviations < 10%, with minimal matrix interferences. The developed method demonstrated superior performance in terms of extraction time, cost, efficiency, and analytical reliability, making it suitable for routine laboratory testing.
