从自燃煤矸石中提取聚合铝铁(PAFC)的试验研究

采用盐酸酸浸的方法从自燃煤矸石中提取聚合铝铁，对煤矸石的粉碎粒径、酸浸盐酸的浓度及用量、酸浸的温度等工艺条件进行了试验研究。结果表明，从100g自燃煤矸石中，可提取19．85g固体聚合铝铁，成品的Al2O3含量33％、Fe2O3含量16％、盐基度70％。     

俄罗斯环境管理问题所引发的法律思考

对俄罗斯的环境管理观念，相关环境法律规定的生态化要求，联邦及联邦各主体两级关系协调化以及环境管理手段的经济化与多样化倾向等问题作了着重分析，并鉴于中俄在历史上社会与经济制度的关联性及正处经济转轨的共同性，希望通过比较中俄两国在历史和现实发展中存在的异同与联系，以求能为我国进一步的环境管理立法提供借鉴性的思考。

Toxic metals in sewage sludge-amended soils: has promotion of beneficial use discounted the risks?

Land application of contaminated waste products has been defended as beneficial use by some scientists and regulators, based on the premise that the behavior of any toxins accumulated in soils from this practice is reasonably well understood and will not have detrimental agronomic or environmental impacts into the foreseeable future. In this review, I use the case of toxic metals in sewage sludges applied to agricultural land to illustrate that metal behavior in soils and plant uptake is difficult to generalize because it is strongly dependent on the nature of the metal, sludge, soil properties and crop. Nevertheless, permitted agricultural loadings of toxic metals from sewage sludges are typically regulated using the sole criterion of total metal loading or concentrations in soils. Several critical generalizing assumptions about the behavior of sludge-borne metals in soil-crop systems, built into the US EPA risk assessment for metals, have tended to underestimate risks and are shown not to be well justified by published research. It is argued that, in the absence of a basic understanding of metal behavior in each specific situation, a more precautionary approach to toxic metal additions to soils is warranted.

A comparison of hydrocarbons emission from engine running 85# gasoline and M-100 methanol fuel

Increasing global interest in methanoi fuel has led us to investigate the exhaust emissionsof its engine. Analysis of its inorganic and organic emissions. such as CO. NO_x and hydrocarbons(total HC) have been widely reported. This paper presents an analysis of more than 20 kinds ofhydrocarbons in the emissions obtained from a spark-ignition Shanghai car running 85^# gasoline anda comparison with emission from a Santana test car running M-100 methanol fuel. A set ofenrichment method has also been described. Test results show that at the current stage of methanolengine development the concentration of individual hydrocarbon including some poisonous substancesis lower than those of normal gasoline engine.     

Carrier screening for cystic fibrosis

A number of different models of CF carrier screening have now been tested in pilot trials. Apart from opportunistic and cascade testing (which are strictly speaking not true forms of screening), the major programmes have been directed either to young adults in primary care or to pregnant women in antenatal clinics. Only in the latter form of screening has sufficient data been collected to allow conclusions to be reached on the optimum mode of delivery. It seems very probable that when CF carrier screening passes into routine service, it will be the antenatal couple model that is used.
