| 中文摘要 |
| 利用玻璃板采样器采集并分析天津市南排污河下游至渤海湾入口处水体表面微层(SM)中五氯酚(PCP)的富集系数,然后在实验室中进行了微宇宙模拟实验,初步探讨了富集原因.现场监测结果表明:PCP在水体表面微层中有一定程度的富集,一般富集系数在1.16～4.11 之间;其富集可能与悬浮颗粒物在SM 中的富集、盐度、大气沉降过程等有关,与TOC无关.实验室研究结果表明:PCP在水体表面微层中富集倍数随悬浮颗粒物浓度和盐度增大而提高,紊动对富集程度无影响。 |
| 英文摘要 |
| The surface microlayer (SM) water samples and subsurface water samples were collected using a glass plate from South Wastewater Canal,Tianjin,China.The enrichment phenomenon of pentachlorophenol(PCP)in SM samples was studied,and microcosm technique was also used.The results from field samples showed that the enrichment factors of PCP in SM samples were mostly in the range of 1.16～4.11,and may be influenced by the enrichment of suspended particulate,salinity and air particle deposition,but weren't related to TOC.The results in laboratory showed that the enrichment factors of PCP in SM samples increased with increasing suspended particulate concentration and salinity,but wasn't related to turbulence. |
