三种固体废弃物综合利用的初步研究

从环境建设的可持续发展出发 ,结合天津开发区在基础设施及园林绿化建设中面临土源紧缺以及周边地区存在大量的海湾泥、粉煤灰、碱渣土等固体废弃物的现实 ,在详细研究了3种废物的物理、化学性质的基础上探讨了用这些废物代替农田客土的可行性。实验及推广应用结果表明 ,这些废物按适当比例混合后能够形成一种可替代种植客土的新型土壤 ,这种新型土壤的最佳配比(即海湾泥与粉煤灰或碱渣土 )比例为3:1 ,同时该配比基质对植物生长的适宜性优于滨海盐土。     

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.

食品产地环境质量评价的可视化

用Microsoft Excel编制的系统程序对食品产地环境空气、水和土壤质量，按农业部颁绿色食品（旱田、水田）、无公害食品标准实施模糊综合评价。程序依土壤的PH值自动按偏酸、中性、偏碱土壤的标准评价。以直观的柱形图、袭输出不同地块环境质量比较、各地块达标及各环境要素、各因子污染状况的结果。使食品产地环境质量的评价实现可视化。
