鄰苯二甲酸酯類做為塑化劑常廣泛使用於塑膠工業包裝材質上，因此可能透過不同方式的溶出而污染 食物，其為內分泌干擾物質，已被證實與部份癌症發生及造成生殖毒性有關，然而，目前有關臺灣作物中塑 化劑的殘留量研究，仍然不足，特別是對於調查未上市田間蔬菜及水果中含量。本研究係利用氣相及液相層 析串聯式質譜儀，針對臺灣田間蔬菜及水果中鄰苯二甲酸丁基苯甲酯 (benzyl butyl phthalate, BBP)、鄰苯二甲 酸二丁酯 (di-n-butyl phthalate, DBP)、鄰苯二甲酸二 (2-乙基己基) 酯 (di-2-ethylhexyl phthalate, DEHP)、鄰苯二甲 酸二異癸酯 (diisodecyl phthalate, DIDP)、鄰苯二甲酸二異壬酯 (diisononyl phthalate, DINP) 及鄰苯二甲酸二辛酯 (dinoctyl phthalate, DNOP) 等6種鄰苯二甲酸酯類含量測定。自2011年7月至12月止，直接由臺灣北中南三大蔬果 產區各採集未包裝30件蔬菜及30件水果進行檢驗分析，樣品中計有12件蔬菜及5件水果樣品檢出含有鄰苯二甲 酸二 (2-乙基己基) 酯塑化劑，殘留量分別為0.02-0.10 mg/kg及0.02-0.08 mg/kg，1件蔬菜樣品檢出鄰苯二甲酸二 丁酯，殘留量為0.02 mg/kg，所有蔬果樣品檢出鄰苯二甲酸酯類含量皆低於臺灣衛生福利部食品藥物管理署訂 立之食品篩檢值1.0 mg/kg。另以蔬果樣品中檢出鄰苯二甲酸酯類最高殘留量，與臺灣所訂定的每日耐受量參 考值 (tolerable daily intake, TDI) 相較，國人經由食入未經包裝處理之蔬果而暴露於鄰苯二甲酸二 (2-乙基己基) 酯類的量 (TDI for DEHP: 0.05 mg/kg bw/day)，分別佔每日耐受量參考值的1.08%和0.53%，食入未經包裝處理之蔬菜而暴露於鄰苯二甲酸二丁酯的量，則佔每日耐受量參考值的1.08% (TDI for DBP: 0.01 mg/kg bw/day)。由上 述結果得知，國人可能食入含鄰苯二甲酸二 (2-乙基己基) 酯和鄰苯二甲酸二丁酯等塑化劑污染之蔬果，但臺 灣栽種蔬果遭受鄰苯二甲酸酯類塑化劑污染情況並不嚴重，產地蔬果中6種鄰苯二甲酸酯類塑化劑濃度仍低於 政府訂立之食品篩檢值。

Phthalates are widely used plasticizers worldwide, and can contaminate food through leaching from various pathways. These compounds may be involved in cancer, and cause damage to the reproductive system in the form of endocrine disruptors. However, few studies have investigated phthalates in Taiwanese crops. This study investigated the residues of six phthalates- benzyl butyl phthalate (BBP), di-n-butyl phthalate (DBP), di-2-ethylhexyl phthalate (DEHP), diisodecyl phthalate (DIDP), diisononyl phthalate (DINP), and dinoctyl phthalate—(DNOP) in field vegetables and fruits in Taiwan by using GC/MS-MS or LC/MS-MS. The 30 vegetable and 30 fruit samples were collected unpackaged and directly from the fields of production in three specific regions in Taiwan between July and December, 2011. DEHP concentrations were detected, and ranged from 0.02 to 0.10 mg/kg in 12 vegetable samples, and 0.02 to 0.08 mg/kg in five fruit samples. In addition, DBP residue was detected in one vegetable sample at 0.02 mg/kg. Therefore, the concentrations of DBP and DEHP were lower than the screening value of 1.0 mg/kg, as defined by the Taiwan Food and Drug Administration (TFDA). However, the hypothetical highest detected value of the estimated daily intake of DEHP in vegetables and fruits reached 1.08% and 0.53%, respectively, of Taiwan’s tolerable daily intake (TDI) for phthalates (TDI for DEHP: 0.05 mg/kg bw/day). The intake of DBP through the consumption of vegetables was 1.08% of the TDI (TDI for DBP: 0.01 mg/kg bw/day). The findings indicated that cultivated vegetables and crops were not severely contaminated by the six investigated phthalate compounds, and the body burden of DEHP and DBP in Taiwanese consumers, which was caused by ingesting field vegetables and fruits, was negligible. The concentration of the six phthalate compounds in field vegetables and fruits was under the specified threshold of phthalates, as specified by the TFDA.
