Poultry eggs from cage, ecological and free range production were analyzed in terms of perfluoroalkyl substances (PFASs). Taking into account all fourteen analyzed compounds, perfluorobutanoic acid (PFBA) reach the highest concentrations (mean 0.23, 0.24, 0.27 μg/kg wet weight (w.w) for organic, cage and free range eggs respectively. Taking into account the lower bound sum of four PFASs: PFOS, PFOA, PFNA, PFHxS which according to EFSA, made up half of the lower bound exposure to PFASs, organic eggs were the most contaminated (0.10 μg/kg wet weight) followed by free range (0.04 μg/kg wet weight) and battery cage (0.00 μg/kg wet weight). The percentage share in the lower bound concentration indicates the dominant role of PFOS (37-100%). Linear PFOS accounted for 71-92% of the sum of linear and branched PFOS. Estimates of PFOS, PFOA, PFNA, PFHxS intake via eggs based lower-bound concentrations were 0.00-0.65 ng/kg b. w for children and 0.00-0.21 ng/kg b. w for adults which corresponds to 0-15% of the tolerable weekly intake (TWI) and 0-5% TWI for children and adult respectively.
本研究分析了笼养、生态放养和散养禽类鸡蛋中的全氟烷基物质（PFASs）。考虑到所有 14 种分析化合物，全氟丁酸（PFBA）的浓度最高（有机鸡蛋、笼养鸡蛋和散养鸡蛋中分别为 0.23、0.24 和 0.27μg/kg 湿重）。考虑到四种 PFASs（PFOS、PFOA、PFNA 和 PFHxS）的下限总和，根据 EFSA 的说法，这四种 PFASs 构成了 PFASs 下限暴露量的一半，其中有机鸡蛋的污染最严重（0.10μg/kg 湿重），其次是散养鸡蛋（0.04μg/kg 湿重）和笼养鸡蛋（0.00μg/kg 湿重）。在下限浓度中所占的百分比表明 PFOS 的主导作用（37-100%）。线性 PFOS 占线性和支链 PFOS 总和的 71-92%。基于下限浓度，通过鸡蛋摄入的 PFOS、PFOA、PFNA 和 PFHxS 的估计摄入量分别为儿童 0.00-0.65ng/kg 体重和成人 0.00-0.21ng/kg 体重，这相当于可耐受每周摄入量（TWI）的 0-15%和儿童和成人 TWI 的 0-5%。
