浅谈火电厂烟气连续监测系统（CEM）

近几年，随着我国环境保护意识的不断提高，环境保护工作也日益加强，为了做到环境和经济持续协调发展，必须要求建设项目加强污染防治对策，加强环保管理部门的有效监督。火电厂装设烟气连续监测系统（CEM）就是对其大气污染物的排放进行连续监测，为生产运行和环保管理部门提供基础数据，本文介绍了电厂CEM系统的分析系统。     

人工快速渗滤系统处理糖蜜酒精废水的研究

本实验研究应用人工快速渗滤系统处理糖蜜酒精废水,实验结果表明,当湿干比为1∶1,配水时间4 h,处理效果最佳,负荷可达到2.13～2.94 m3/(m2·d).在进水CODCr浓度＜800 mg/L时,CODCr的去除率达到80%以上,但随着进水CODCr浓度的升高,CODCr的去除率缓慢下降,当CODCr浓度超出2 500 mg/L时,系统的生物膜降解不再发生作用,只存在简单的机械过滤作用.

Chorionic villus sampling and acceptance rate of prenatal diagnosis

In this paper, we compared the acceptance rate of fetal diagnosis for β-thalassemia in three group of couples of Sardinian descent; the first counselled before DNA analysis was available, the second presenting after DNA analysis was introduced but too late for chorionic villus sampling and thus monitored by amniocyte DNA analysis and the third presenting within the first trimester after DNA analysis was introduced and thus in time for trophoblast DNA analysis. A higher proportion of couples from the latter group opted for fetal testing as compared to the 1st and 2nd group. These results indicate that in this population, introduction of 1st trimester diagnosis made prenatal testing acceptable to practically all counselled couples at risk.     

淮河流域非木浆制浆造纸业的发展研究

由于淮河流域水环境污染严重，国家已将造纸业特别是小造纸列为淮河流域水环境重点治理对象之一。淮河流域造纸业多为草浆制浆，具有技术，经济与污染治理的特殊性。结合我国造纸工业发展历程和行业现状以及面临的挑战，分析国内及淮河流域制浆造纸业的产业结构，技术结构和环境影响，阐述麦草在我国制浆造纸业中的战略地位，提出淮河流域草浆制浆业的结构重整建议，探讨淮河流域造纸业可持续发展的途径。     

Secondary effect of SO_2 pollution: enhanced growth of the army worm, Mythimna separata (Walker)

Effects of SO2 pollution on growth of the army worm, Mythimna separata, were investigated by rearing the larvae for 12 days on the wheat plants being exposed to SO2 levels ranged from 50 to 200 ppb in the field open-top fumigation devices. Larval period shortened while their mean relative growth rate (MRGR) increased as SO2 dose elevated. Similar experiment with the insect on the artificial diet excluded the possibility that SO2 pollution directly stimulated growth of the army worm.The patterns of change in amino acid hydrolysates in the host foliage suggested that contents of methionine, and perhaps, arginine in food material exposed to unpolluted air were at such levels that they could only support sub-optimum growth of the insect, and SO2 pollution increased concentrations of these limiting amino acids, resulting in better performance of the larvae.     

藻类－卤虫－对虾系统深度处理含盐含汞化工废水的模拟试验研究

利用藻类－卤虫－对虾系统深度处理含盐含汞化工废水的模拟试验研究表明，该系统对ＢＯＤ＿５和ＣＯＤ去除率分别达９５．５％和８０．０％，对ＰＯ和Ｈｇ￣（２＋）去除率都在９８％以上，在卤虫密度５２．１个／Ｌ和３６．０个／Ｌ，藻类密度２５７２５．８万个／Ｌ和２０９２４．９万个／Ｌ，水中汞能被不同营养等级的生物累积，在水中汞浓度１．０×１０￣（－４）－３．０×１０￣（－４）ｍｇ／Ｌ范围内，藻类和卤虫对水中汞的浓缩倍数分别为７．５×１０￣２－７．８－１０￣３和２．１０×１０￣２－１．０４×１０￣４；卤虫吞食藻类，它对藻体中汞的浓缩倍数较低，变化范围在０．１－１．７之间；食染汞卤虫的对虾对汞的累积不明显。
