NPPs (Non-phthalate plasticizers) are used as alternative plasticizers to phthalate esters, but there is limited knowledge on environmental residues, and they have not been reported in Japan. A method to analyze NPPs in seawater using solid-phase extraction was developed, and the residual burden of Diisobutyl adipate (DIBA), Acetyl tributyl citrate (ATBC), Di-(2-ethylhexyl) adipate (DEHA), Di-(2-ethylhexyl) sebacate (DEHS) and Trioctyl trimellitate (TOTM) in seawater and sediment from the Osaka Bay was measured. Using an Oasis Max column and acetone as the eluting solvent, the recovery of the target substances in seawater is >68 %. In Osaka Bay, no NPPs were detected in seawater. On the other hand, ATBC and TOTM were detected in the sediment at 36–69 ng/g and 47–131 ng/g, respectively, from about half of the 14 sites, while DEHA and DEHS were detected at 83 ng/g and 181 ng/g, respectively, from only one site.

日本大阪湾海水和沉积物中非邻苯二甲酸酯增塑剂残留
NPPs（非邻苯二甲酸酯类增塑剂）被用作邻苯二甲酸酯类增塑剂的替代品，但对环境残留物的了解有限，在日本尚未见报道。建立了固相萃取分析海水中 NPP 的方法，并测定了己二酸二异丁酯 (DIBA)、柠檬酸乙酰三丁酯 (ATBC)、己二酸二(2-乙基己基)酯 (DEHA)、二-(2-测量了大阪湾海水和沉积物中的癸二酸乙基己酯 (DEHS) 和偏苯三酸三辛酯 (TOTM)。使用 Oasis Max 色谱柱，丙酮作为洗脱溶剂，海水中目标物质的回收率 >68%。在大阪湾海水中未检测到核电站。另一方面，在 14 个站点中约一半的沉积物中检测到 ATBC 和 TOTM，浓度分别为 36–69 ng/g 和 47–131 ng/g，而 DEHA 和 DEHS 检测到 83 ng/g 和 83 ng/g。仅来自一个站点，分别为 181 ng/g。
