为探明冬瓜果实、茎、叶柄及叶片能否从大气环境中吸收DEHP。采用气相色谱／质谱联机检测技术测定冬瓜根、茎及叶中DEHP的含量，并分析期果实中DEHP的分布情况。结果表明：叶片中DEHP的含量是根中的6倍，从底部到顶部茎叶中DEHP的含量依次降低。相邻部位DEHP含量为叶柄＞叶片＞茎。冬瓜果皮中累积的DEHP高，果肉相对较低，进一步证明了植物吸收DEHP不是来源于地下部分而是来自于地上部分。

The aims of present research intent to prove the fruits ,stems ,petioles and leaves of wax gourd (Ben‐incasa hispida) can absorb di‐2‐ethylhexyl phthalate (DEHP) from atmospheric environment .DEHP contents of roots ,stems ,leaves and fruits of Benincasa hispida were measured and analyzed by GC‐MS equipped with an HP‐5 trace analysis column .The results show that the DEHP content of leaves was 6 times of the root ,DE‐HP contents of stems and leaves gradually reduced from bottom to top ;the DEHP contents of adjacent parts were petioles > leaves > stems ;The accumulation of DEHP in peel was higher than pulp ,this result demon‐strated that the wax gourd accumulated DEHP mainly from the aerial parts but not from underground parts .
