论水污染物排放统计指标体系

水污染物排放统计指标体系包括水污染物排放统计指标以及排放管理指标,统计对象主要是规模以上点源。实施统计的污染源的规模应当是全国统一的。统计指标区分为指标、主要参数和辅助参数,既便于理解也便于管理;将排放指标细化为污染源排放量、入河排放量和通量使得排放概念更加清晰,有利于水环境管理。对入河排放量和污染源排放量的比较,可以确定纳入统计范围的污染源的代表性,对通量和入河排放量的比较可以推断非点源污染物排放状况。以流域为单元的,以通量、入河排放量和污染源排放量为主要概念的排放统计管理方式,有助于提高流域水污染防治的确定性和一致性。     

Project of an Air Quality Monitoring Network for Industrial Site in Italy

In this paper results concerning project of an atmospheric monitoring network applied to an area of south of Italy carried out using chemical measurement campaigns (for traffic emissions characterisation couple with diffusional simulation of industrial pollutant emissions will be presented. The area selected is characterised by an high concentration of high environmental impacting industrial activities, with also high concentration of urban settlement and vehicular traffic. A comprehensive definition of all the monitoring system to be installed in order to have a correct monitoring system for the all province will be described and discussed.

环境影响评价中空气污染物环境容量计算模式的研究

通过对贵州省安龙县德卧工业园区大气环境影响评价,提出了一种以大气污染物排放参数和污染气象条件等为基本参数的空气污染物环境容量简便计算方法,计算了该园区TSP和SO2的空气环境容量。并以TSP为例,与采用常用的箱模式A值法的计算结果进行了对比,表明两种模式的结果具有良好的一致性。

中日公害赔偿法律制度比较

中日公害赔偿法律制度在无过错（过失）责任的含义、因果关系的认定、损害赔偿范围在原则上存在差异。中国应借鉴日本公害赔偿法律制度的优点，进一步完善“无过错责任”理论、加强判例研究以及建立多层次的环境污染赔偿责任立法体系。     

Sedimentation of short cylindrical pollutants with mechanical contacts

Lattice Boltzmann method and elastic particle collision model were used to investigate the sedimentation of short cylindrical pollutant particles with mechanical contacts for varying bulk number density ε and terminal Reynolds number ReT. The corresponding experiments were performed as a comparison. The clusters of pollutant particles with an inverted “T” structure were observed, the pollutant particles for high ε and large ReT scattered wider than that for low ε and small ReT. The sedimentation velocities increased suddenly at the initial stage, then decreased drastically, after that swayed around and approached to a steady value. The time to steady state did not depend on ε and ReT. The effect of particle interactions was to hinder the average sedimentation velocity, and hindrance was directly proportional to ε. The orientation distributions of pollutant particles depended on ReT and ε, especially on the former. Both the standard deviations of vertical and horizontal velocity, the former was larger than the latter, were nearly independent on ε and ReT.
