富Ca^2＋柠檬酸废水的处理

采用近三年废水处理厂的实际运行数据，分析了Ca^2 对厌氧和好氧的影响。在选用的工艺中，IC塔能适应高Ca^2 废水，不论是厌氧还是氧，Ca^2 对COD的去除都无影响。     

中国东、西部工业污染和经济发展的分析比较

从经济发展水平和工业污染排放角度出发,对比分析了东部、中部和西部3个地区的差异。结果表明,90年代以来,中国的经济发展和工业污染在东、西部之间存在着较显著的差异,所表现出的综合效应是形成了明显的工业污染物排放强度梯度。即在空间上,工业污染物排放强度存在从东部、中部到西部逐渐升高的梯度。建议在西部大开发过程中,要充分利用西部环境保护的后发优势,减缓或遏制工业污染的“西迁”,实现环境保护的跨越式发展。     

水中溶解性苯紫外光解产物苯酚的过程研究

GC（气相色谱）分析表明，溶解在水中的苯在UV（紫外光）作用下可以转化成苯酚。DO（溶解氧）和高pH对苯酚的产生有利。低pH抑制苯酚的产生。反应机理分析表明，苯既可以和DO反应，又可以和氢氧根或以应产生苯酚。     

Carbon mitigation potential and costs of forestry options in Brazil,China, India,Indonesia, Mexico,the Philippines and Tanzania

This paper summarizes studies of carbon (C) mitigation potential and costs of about 40 forestry options in seven developing countries. Each study uses the same methodological approach – Comprehensive Mitigation Assessment Process (COMAP) – to estimate the above parameters between 2000 and 2030. The approach requires the projection of baseline and mitigation land-use scenarios. Coupled with data on a per ha basis on C sequestration or avoidance, and costs and benefits, it allows the estimation of monetary benefit per Mg C, and the total costs and carbon potential. The results show that about half (3.0 Pg C) the cumulative mitigation potential of 6.2 Petagram (Pg) C between 2000 and 2030 in the seven countries (about 200× 10⁶ Mg C yr^-1) could be achieved at a negative cost and the remainder at costs ranging up to $100 Mg C^-1. About 5 Pg C could be achieved, at a cost less than $20 per Mg C. Negative cost potential indicates that non-carbon revenue is sufficient to offset direct costs of these options. The achievable potential is likely to be smaller, however, due to market, institutional, and sociocultural barriers that can delay or prevent the implementation of the analyzed options.     

黄海北部对虾放流水域污染分析

根据１９９６－１９９８年对黄海北部中国虾放流增殖水域的调查，对该水域的污染状 评价，结果表明，除个别站位ＣＯＤ、Ｃｕ、Ｚｎ、Ｈｇ有少量超标外，综合评价和单因子评价均符合渔业水质标准规定的要求，水质良好，适合幼对虾的栖息和生长。但污染物含量特别是重金属含量有逐年增高的趋势。     

重大环境污染事故的防范及紧急处置

重大环境污染事故危害重大，为及时防范和处置，应对其隐患者监护和事故性风险评估，建立紧急救助的快速反应系统和紧急处置询系统，开发专家系统，强化专业人员培训并建立国家的安全信息数据库。
