建立完善中国船舶污染防治法规体系的必要性及建议

完善的船舶污染防治法规是搞好中国船舶污染防治工作的基础，但中国现有船舶污染防治法规还存在着各部分发展不平衡、法规不健全等问题。要完善中国船舶污染防治法规，必须以体系的观点对现有船舶污染防治法规进行审视，把其建设成为一套有别于其它污染防治法规的完善的、相对独立的体系。文中就此展开论述并提出了相应的建议。     

利用石化污泥生产新型除油吸附剂的试验研究

利用量大面广的石化污泥制备吸附材料用于水表面油的清除。该吸附剂制备的最佳工艺条件为：料层厚度65mm，碳化温度360℃-400℃，炭化时间4.5-5h。所制备的吸附剂具有很强的亲油疏水性和100%的悬浮率，20℃时对原油的饱和吸附量达到7.7g/g。

Levels of polycyclic aromatic hydrocarbons in some agricultural, industrial and urban areas along Xiamen coastal waters, China

An intensive investigation was conducted to study the distribution of polycyclic aromatic hydrocarbons （PAHs）, to show firstly the level of pollution in the agricultural areas and analyses specifically the status of soil polluted by these persistent pollutants in some locations of Xiamen region. Soil samples collected from Jiulong agricultural catchment have been analysed for 16 PAH compounds, using gas chromatography flame ionization detection in order to determine the level of selected PAH components and to identify the factors that may control their distribution and persistence in the area. The main PAHs found in soil samples were the low molecular weight. The total PAHs detected in soil samples ranged from 0.50 to 0.95 μg/g soil. The highest values of PAHs were significantly detected in the orange tree leaves, which range from 236.1 to 249.3 μg/g soil showing recent atmospheric inputs of these volatile pollutants. The distribution of PAHs in vegetable were monitored and indicating that the concentration were high and ranged from 8.24 to 58.87 μg/g. Other sediment samples were also collected and analysed from urban sewage （5.26 μg/g dw）, aquacultural （0.52 μg/g dw） and industrial areas （from 0.62 to 2.09 μg/g dw）, during this investigation. The contamination of Jiulong river estuary and Xiamen Western Sea by PAHs has been then widely justified by wastcwatcr discharges and soil runoffs from these areas. The results, therefore, provide important information on the current contamination status caused by the atmospheric transport and point to the need for urgent actions to stop the release of these hydrocarbons to the environment. The necessity of implementing systematic monitoring of PAHs is also emphasized.
