在江苏省开展建设工程第三方环境监理的思考

目前国内部分省市已陆续开展建设工程环境监理的试点工作，并取得一些好的经验。本文通过分析开展第三方环境监理工作的必要性和国内几家试点工作的进展情况，提出了在江苏省开展建设工程第三方环境监理工作的对策。     

利用风场资料研究中距离大气扩散规律

本文提出了一个利用气象观测网取得的测风资料研究中距离大气扩散规律的方法。根据常规的风场观测资料和高空风观测资料,用插值公式计算地面和200m高度的水平轨迹以及水平风纵向分量和横向分量的脉动时间序列,进而用相继两条轨迹的横向距离和风脉动滑动平均法求得各类稳定度下的大气扩散参数。计算结果与同时进行的SF_6示踪实验结果和不同时进行的平衡球双经纬仪定位结果基本符合。     

广州大田山垃圾填埋场空气中微量挥发有机污染物组成

以广州大田山垃圾填埋场为例，研究了在不同季节填埋场空气中微量挥发性有机污染物的种类和含量变化情况。结果表明，在春、夏季样品中可分别检测出47和64种化合物，其中有些化合物为USEPA优先控制毒害有机污染物；夏季样品中微量挥发性有机污染物的浓度大多比春季样品高，有的甚至高1个数量级以上。因此加强对垃圾的卫生填埋，尤其是加强对夏季的垃圾卫生填埋的科学管理，减少挥发性有机污染物向大气中的扩散，应给予充分的关注。     

饮用水中铝的萃取-高效液相色谱分析

拟定了金属配合物的萃取 -高效液相色谱法。Al与 8-羟基喹啉反应生成的黄色配合物 ,用氯仿萃取 ,在C8烷基键合固定相上 ,以甲醇 -乙酸乙酯 -水 (体积比 4 0 :2 0 :4 0 )为流动相 ,于波长390nm处测定饮用水中总Al的含量 ( 2 0 -70 0 μg/L)。对萃取条件和萃取百分率 ,色谱分离条件进行了研究 ,讨论了测定的灵敏度、选择性和重现性。     

商厦火灾危险性评价研究

商厦火灾是火灾中危害性较大的灾害之一，常常造成人员的大量伤亡和巨大的财产损失。商厦火灾危险性评价是一个减少火灾危险性的可行方法。在基于影响商厦火灾危险性因素之上，讨论了评价指标体系的建立及量化和权重的处理方法，然后应用模糊数学理论建立了评价商厦火灾的模糊评价模型，对商厦火灾的预防与商厦消防管理具有指导意义。     

个体防护装备管理软件的研制与开发

使用个体防护装备是为了预防工伤事故和职业病而采取的一项预防措施,关系到每个一线职工在生产作业过程中的安全与健康,因此个体防护装备必须按时、按量、及时发放到职工手中.但由于个人防护涉及的对象多、工种繁杂、标准不一,这就给个体防护装备的发放管理带来了许多困难.多年来个体防护装备的管理一直沿用手工建立各种帐册的方法,使这项工作效率低,时有漏发、晚发的问题.为此,我们研制开发了““个体防护装备管理““软件,经过一年多的使用,效果良好.

人工湿地基质对NH4＋-N吸附性能

为研究建筑废物红砖和工业废物煤渣用作人工湿地脱氮基质的可行性，分别通过静态吸附实验和动态NHf—N去除效果实验进行考察。结果表明，红砖和煤渣对NH4＋-N最大静态吸附量分别为0．2533mg／g和0．0533mg／g，其吸附等温曲线均符合Freundlich型吸附方程，吸附常数分别为0．0419和0．0091；红砖煤渣组合对污水中NH4＋-N平均动态脱除率达到41．18％，高于红砖的37．63％和煤渣的30．92％。     

Impact assessment of human diet changes with rapid urbanization on regional nitrogen and phosphorus flows—a case study of the megacity Shanghai

Regional material flows are strongly influenced by human diets. To diagnose and prevent environmental problems that threaten urban sustainability, the impact of human diet changes with rapid urbanization on the regional nitrogen (N) and phosphorus (P) flows were quantitatively evaluated. A survey of day-to-day activities was conducted of 450 individuals surveyed (adults over 18 years old) in three representative areas (the central district, the new district, and the suburban/rural areas) of Shanghai, a megacity which has attracted worldwide attention. The lifestyle (eating habits, domestic sanitation, drainage facilities, etc.) pattern was determined and the potential N and P loads from human diets on the environment were calculated. The daily potential nitrogen and phosphorus loads from human diets was 19.36 g-N, 1.80 g-P in the central district, 16.48 g-N, 1.52 g-P in the new district, and 13.04 g-N, 1.20 g-P in the suburban/rural areas of Shanghai. Respondents in all three areas, especially those in the suburban/rural areas reported a preference for increasing the intake of animal-derived as well as processed foods, which means that the potential N and P load from human diets to the environment will increase further. In addition, most respondents consider industrial wastewater discharge as the main cause of eutrophication of waterbodies, though in recent years water pollution caused by domestic wastewater has increased rapidly, but this has received much less attention. Environment-friendly eating habits and improvements in the environmental awareness will be required.
