上海滨岸潮滩不同粒径沉积物中无机形态磷的分布特征

以地理环境独特的上海滨岸带为研究对象，根据对冬季潮滩悬浮层、表层沉积物的研究，初步探讨了潮滩不同粒径沉积物中各无机形态磷的地球化学特征：DP、(Fe Al)-P在靠近排污口的采样点含量高，同时随粒径变化复杂；沉积物中（Fe Al)-P含量随粒径变大而升高，悬浮层沉积物中（Fe Al)-P更能指示环境的污染状况；一般细粉砂质沉积物中Ca-P含量高。     

Kinetic-spectrophotometric determination of free cyanide by stopped-flow reversed flow injection analysis

A stopped-flow reversed flow injection method for the determination of free cyanide is proposed. Pyridine-barbituric acid mixture is injected in the flow system as reagent to form the colour species with cyanide. The flow is stopped when the reagent zone comes in the flow cell, where absorbance-time data are collected at 580nm wavelength. The linear range of the determination is 0.1 -10μg/ml CN-. The sampling rate is 60h-1 and the relative standard deviation is 1.6% (n=16) at 5.0 μg/ml CN-1 level. With satisfactory results, the proposed method was applied to the determination of free cyanide in wastewater without sample pretreatment.     

The epidemic characteristics of Kaschin-Beck disease (KBD) in different eco-environments

Epidemiological survey of 573 families, clinical examination of 2593 persons, and X-ray examination of 1136 persons (in 16 typical endemic villages) were conducted, based on the classification of endemiology for KBD disease areas, i.e, mountain type, loess plateau type, plateau type, and flatlands type. It was revealed that the KBD disease areas exhibited the regular pattern of corming-into-being, development and passing-away and the characteristics of growth and decline. Further, it was found clinically that the disease areas may be divided into 4 types, i.e., recent onset, developing, stable, and historical. This division is simple and easy, practical, scientific, and reliable and can be applied by medical personnel at different levels.     

环境矿物材料在微污染水处理中的应用前景

自来水厂传统工艺对水中微量有机物没有明显的去除效果，常规净化工艺也很难去除重金属离子和氨氮等涪染物。环境矿物材料具有来源广泛和良好的使用性能、无生态副作用等特点，对微污染水具有较好的处理效果。本文论述了沸石和磷灰石对污染物的去除机理，探讨了基于环境矿物材料的人工快滤系统在净化微污染水中的应用前景。
