采集了莱州湾海域14个站位的表层沉积物,对其邻苯二甲酸二丁酯(DBP)和邻苯二甲酸双(2-乙基己基)酯(DE-HP)含量与分布进行了调查研究。结果表明,DBP和DEHP是莱州湾表层沉积物主要的酞酸酯类有机物;莱州湾调查海域DBP含量范围为:(2.002~43.891)×10-9,DEHP含量范围为:(4.454~4389.243)×10-9;莱州湾海域沉积物中DBP和DE-HP含量分布差异显著,西部海域沉积物中DBP和DEHP含量明显高于中、东部海域。
The surface sediments of 14 stations in the Laizhou Bay area were collected and the content and distribution of dibutyl phthalate (DBP) and bis (2-ethylhexyl) phthalate (DE-HP) Research. The results showed that DBP and DEHP were the main phthalate esters in the surface sediments of Laizhou Bay. The DBP content in the surveyed waters of Laizhou Bay was (2.002 ~ 43.891) × 10-9, and the range of DEHP content was (4.454 ~ 4389.243) × There was significant difference in the distribution of DBP and DE-HP in the sediments of the Laizhou Bay area. The contents of DBP and DEHP in the sediments of the western area were significantly higher than those in the middle and eastern sea areas.
