Description
Summary:The presence of endocrine disrupting chemicals such as 4-n-octylphenol, 4-n-nonylphenol and bisphenol A in environmental samples and artificial products may cause health problems for human and organisms. This developed method was efficient for monitoring of those tracing emerging contaminates and the Plackett-Burman factorial design introduced in extraction step was timesaving. Matrix effect was also considered to ensure proper quantitation. Good linearity (r2>0.99), low Method Detection Limits (MDL) and Method Quantitation Limits (MQL) range from 0.18 to 0.54ng/g and 0.60 to 1.80ng/g were obtained. Three level spiking experiment (4, 10, 15ng/g) showed recoveries range from 74% to 113% for 4-n-octylphenol and 4-n-nonylphenol with RSD range from 2% to 11%. The method was finally applied to the analysis of real fish samples taken from Hunan Province, China, offering a reliable and effective means for monitoring of trace emerging contaminates in fishes largely consumed by residents. [Display omitted] •The QuEChERS-based method was used to detect 4-n-OP, 4-n-NP, BPA in fish.•The Plackett-Burman factorial design for screening the main factor was timesaving.•Matrix effect was reduced by matrix-matched internal standard method.
