研究邻苯二甲酸二丁酯（ＤＢＰ），邻苯二甲酸二异辛酯（ＤＥＨＰ）和阴离子表面活性剂在水体表面微层的富集行为．现场分析结果表明邻苯二甲酸酯在小型封闭湖泊表面微层中存在富集现象，富集倍数在１～１１之间，湖水的理化性质及采样方式均影响富集倍数的大小．室内微宇宙研究表明ＤＢＰ和ＤＥＨＰ在微宇宙水体表面微层中均存在富集现象，富集倍数分别为２．８１和１．９８，藻类、颗粒物和腐殖酸也同时在微宇宙水体表面微层中富集．当水体中加入表面活性物质和腐殖酸时，邻苯二甲酸酯（ＤＢＰ、ＤＥＨＰ）在表面微层的富集倍数随加入的２种物质浓度的增大而降低．对阴离子表面活性剂的富集动力学研究表明，当表面微层遭到破坏后，其在表面微层达富集平衡需较长时间，水体浓度也影响富集倍数
To study the enrichment behavior of micro-layers on the surface of water by using dibutyl phthalate (DBP), diisooctyl phthalate (DEHP) and anionic surfactants. The results of on-site analysis showed that phthalate was enriched in the micro-surface of small closed lakes and the enrichment factor was between 1 and 11. The physicochemical properties and sampling methods of the lake affected the enrichment factor. Indoor micro-universe research shows that DBP and DEHP are enriched in the micro-universe surface water micro-layer, enrichment multiples were 2.81 and 1.98, respectively, algae, particulate matter and humic acid micro-universe at the same time micro-surface water Rich in layers. When the surface active substances and humic acid were added to water, the enrichment factor of phthalate esters (DBP, DEHP) in the surface micro-layer decreased with the increase of the concentration of the two substances added. The enrichment kinetics of anionic surfactant shows that when the surface micro-layer is damaged, it takes a long time for the micro-layer to be enriched in the surface, and the concentration of water also affects the enrichment factor
