辽东湾浅水区水环境质量现状评价

根据1999年8月调查资料，对辽东湾浅水区的水质进行评价。结果表明：该海域大部分涨水指标达到一类水质标准。但无机氮、重金属Pb超标比较严重。河口附近海域水质较差，远岸水质相对较好。     

呼和浩特市大气中酞酸酯的初步研究

通过对呼和浩特市不同功能区和不同季度的大气中酞酸酯污染物的采样监测调查，证实了酞酯不仅存在于大气中，且浓度比较高，为５３１ｎｇ／ｍ＾３，是草原地区背景值（１０－３３ｎｇ／ｍ＾３）的１６倍以上。根据调查表明，不同功能区中大气中酞酸酯（ＤＮＢＰ和ＤＥＨＰ）的浓度差异较大；相同功能区的不同季节，酞酸酯浓度也存在较大差异，但酞酸酯浓度与大气颗粒物呈现出良好的相关性，冬、夏季的相关系数分别为０．９７１和０．     

Life-cycle assessment of four types of floor covering

Four types of floor covering have been investigated with respect to their environmental impact: linoleum, cushion vinyl, tufted carpet with a woollen pile and tufted carpet with a polyamide pile. The analysis relates to all stages in the life-cycle (from ‘cradle to grave’) and focuses on floor coverings for domestic use. The analysis is performed by means of the method for life-cycle assessment (Dutch approach). Each floor covering is assessed with regard to its environmental impact. This impact can be of various type: depletion of raw materials, cumulative energy requirement, global warming, acidification, tropospheric ozone creation, stratospheric ozone depletion, eutrophication, production of waste and human health. The inventory of environmental interventions (materials, energy requirements, waste and emissions to air, water and soil) was fairly complete. Most interventions relating to the processes that make up the life-cycle of the floor coverings in question could be quantified. A large part of the data is associated with the process energy requirement. In general these data are quite reliable. The results of the impact assessment for linoleum differs considerably from those for other types of floor coverings. Linoleum turns out to be the most environmentally favourable floor covering. It was not possible to differentiate between the environmental impact of cushion vinyl, tufted carpet with a woollen pile and tufted carpet with a polyamide pile.     

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.
