养殖罗非鱼肉中邻苯二甲酸酯残留分析
Analysis of phthalate esters residue in the tissue of cultured fishes
摘要
Abstract
Six U.S.EPA priority pollutants of Phthalic acid esters（PAEs） with potential effect on disordered endocrine were adopted as objective compounds.Acetonitrile was selected as extraction agent.Fish meat samples added with PAEs standards were treated by ultrasound radiation,enriched by solid-phase extraction on OPT column and followed by GC-FID detection.Six PAEs were separated well in GC spectra.The low detection limits of PAEs were 0.2～3.8μg/kg.The recoveries of the 6 PAEs were 33.7%～92.9% and the relative standard deviations were in the range of 8.7%～14.6%.The main PAEs pollutants in the fish sample from typical aquatic breeding areas in Guangdong province were DMP,DEHP,DnBP and DEP.The DnBP content in fish sample was as high as 38mg/kg and the other three PAEs content was in the range of 0.2～12.8mg/kg.Correlation analysis indicated that the PAEs category and content in fish sample was closely related to that in the relative breeding aquatic water（P0.01）.The accumulation of PAEs in aquaculture water was one of the crucial reasons for PAEs pollution in fishes.It suggested that measures for monitoring and controlling of water resource should be adopted in order to eliminate PAEs pollution in fishes.关键词
