| 1 | 茶叶中多环芳烃污染水平及来源研究进展显示文摘在查阅国内外近20年来相关文献基础上,分析了茶叶中多环芳烃污染水平及分布规律,阐述了多环芳烃在茶叶种植、加工过程中的污染来源、环境行为和生物学效应,提出了新形势下茶叶产地环境对茶叶中多环芳烃污染来源的重要性,可为探寻茶叶中多环芳烃关键控制点,为进一步研究新环境下多环芳烃污染来源和开发风险控制技术提供思路。 | 高贯威 陈红平 刘平香 马桂岑 郝振霞 王晨 柴云峰 鲁成银 | 2016 | 热带作物学报2016，37，10： | 8 |
| 2 | Dissipation of polycyclic aromatic hydrocarbons in crop soils amended with oily sludge显示文摘Oil fields present a potential ecological risk to nearby farmland soil. Here we present a new method designed to evaluate the ability of winter wheat(Triticum aestivum) to contribute to the dissipation of polycyclic aromatic hydrocarbons(PAHs), which are priority pollutants in soils contaminated by oily sludge. The influence of different doses of oily sludge on the dissipation of PAHs was studied along with individual PAH profiles in soils after different periods of plant growth. Five soil samples were artificially contaminated with different percentages of oily sludge(0 %, 5 %, 10 %, 15 % and 20 %). Winter wheat grew in the oily sludge–amended soils for 265 days.PAH content in the soils was monitored over the course of the study. The rate of PAH dissipation is related to the properties of different PAHs, period of winter wheat growth, and oily sludge application dose. Analysis for treated soils indicates that the dissipation of PAHs increased significantly over the first 212 days, followed by minimal changes over the final 53 days of treatment. In contrast, PAH dissipation slowed with increasing oily sludge application. For each PAH, the experimental results showed a significant compound-dependent trend. Winter wheat in the present study significantly enhanced the dissipation of PAHs in oily sludge–contaminated soil. | Shaoping Kuang Wenjuan Yu Yan Song Yaqing Su Huihui Wang Lina Wang | 2016 | Acta Geochimica2016，35，4： | 1 |
