Abstract
A simple method was developed to determine residual p-arsanilic acid (ASA), an organo-arsenic compound used as a
feed additive, in aquatic products (eel, halibut, and shrimp) using EDTA-assisted solvent extraction and LC-MRM. The method
was successfully validated in terms of specificity, linearity (coefficient of determination ≥ 0.995), accuracy (recovery or R,
72.72-78.73%), precision (the relative standard deviation of R, 2.08-6.98%), and sensitivity (the lower limit of quantitation, 5
ppb) according to CODEX guidelines (CAC-GL 71-2009). The use of EDTA in the extraction solvent and water with a suitable
pH modifier as the reconstitution solvent may be the key factors for successful results. This is the first method that can be used
for monitoring residual ASA in aquatic products using LC-MRM and could contribute to establishing a better aquatic product
safety management system.
