环境污染纠纷调处与环境行政处罚之区别浅析——兼与章锦华同志商榷

指出了环境污染纠纷调处与环境行政处罚的性质，程序，结果等均不相同，在理论上不能将两者混一谈，实践中应区别对待。     

我国海洋环境污染监测质量保证的回顾与展望

我国海洋环境污染监测质量保证的发展历史可大致分为三个阶段：孕育阶段（１９７２～１９７７年）起步阶段（１９７８～１９８３年）和发展阶段（１９８４～）。各个阶段有不同的特色和侧重点，１９７８年前主要探索与污染物质的分析方法，１９８４年后是监测质量保证工作进入管理时期。     

基于网格空间数据的晋陕蒙接壤区生态环境综合评价

晋陕蒙接壤区是典型的生态过渡带、生态脆弱带。文章在调查研究的基础上 ,选取了 1 3个评价指标 ,应用层次分析法确定其权重 ,并将各个因子分级标准化和定量赋值 ,再用加权求和法得到每个评价单元的环境质量综合评价指数。根据环境综合评价指数将环境质量分为较好 (≥ 8)、一般 (≥ 6～ <8)、较差 (≥ 4～ <6)、恶劣 (<4) 4级。结果表明 :晋陕蒙接壤区的环境质量大多处于较差等级 ,较好、一般、较差、恶劣等级的面积比例分别为 2 .2 % ,2 8% ,5 7.4%和1 2 .4%

Application of CFD Methods for Modelling in Air Pollution Problems: Possibilities and Gaps

Different urban air pollution problems deal with complex structure of air flows and turbulence. For such problems the Computer Fluid Dynamics (CFD) methods become widely used. However, this approach despite a number of advantages has some problems. Experience of use of CFD tools for development of models and suggestions of their applications for a local scale air pollution over a complex terrain and stable stratification are discussed in this paper, including: Topography and complex geometry: choose of the co-ordinate system and computer grid; Turbulence closure for air pollution modelling: modified k- model for stable stratified ABL; Boundary conditions for vertical profiles of velocity for stable-stratified atmosphere; Effects of the radiation and thermal budget of inclined surfaces to dispersion of pollutants; Artificial sources of air dynamics and circulation.Some examples of CFD applications for air pollution modelling for a flat terrain, mountainous area, mining open cast and indoor ventilation are discussed. Modified k- model for stably-stratified ABL is suggested. Due to the isotropic character of the k- model a combination of it in vertical with the sub-grid turbulence closure in horizontal can be more suitable for ABL. An effective scheme of boundary conditions for velocity profiles, based on the developed similarity theory for stable-stratified ABL, is suggested. Alongside with the common studies of atmospheric dispersion, the CFD methods have also demonstrated a good potential for studying anthropogenic and artificial-ventilation sources of air dynamic and circulation in local-scale processes of air pollution.     

Monitoring of diazinon concentrations and loadings,and identification of geographic origins consequent to stormwater runoff from orchards in the Sacramento River watershed,U.S.A

Diazinon contamination of California's rivers has resulted in placing several rivers on the federal Clean Water Act § 303d list of impaired waterways. Impaired water body listing requiresthe development of Total Maximum Daily Loads (TMDL). Previous studies identified stormwater related diazinon pulses in California rivers. This study was conducted to monitor diazinonconcentrations in the Sacramento River watershed after rainfallevents, to ascertain whether pulses could be identified and, ifconcentrations of concern were observed, to estimate loadings anddetermine geographic origins of the insecticide. TMDL developmentrequires knowledge of contaminant sources, loadings, and geographic origins. Flow and diazinon concentrations peaked in the Sacramento River at Sacramento after the three largest stormsduring January and February 1994. Diazinon concentrations peakedconsequent to each of three storms. Diazinon concentrationsmeasured in the Sacramento River at Sacramento exceeded theCalifornia Department of Fish and Game acute and chroniccriteria for protection of aquatic life during January andFebruary for nine and nineteen days, respectively. Multipleexceedances were observed throughout the watershed. Diazinon loading and geographic origin differed with each of the three storms. The design of this study provides a useful template for others attempting to identify loadings and sources of contaminants in surface waters and to rectify aquatic ecosystemcontamination from various land use practices.

CHLORINATED HYDROCARBON (HCB, DDTs AND PCBs LEVELS IN CETACEANS STRANDED ALONG THE ITALIAN COASTS: AN OVERVIEW

Concentrations of HCB, DDTs and PCBs in the tissues andorgans of cetaceans ( Stenella coeruleoalba, Tursiops truncatus, Balaenoptera physalus, Steno bredanensis}, Grampus griseus} and Globicephala melaena) strandedalong the Italian coasts in the period 1987–1993 are reported. The values are compared between speciesand between specimens of the samespecies. Chlorinated hydrocarbon (CH) levels were found toincrease in relation to the quantity andtype of lipids in each tissue and organ. Differences inaccumulation encountered in the differentspecies are principally due to different feeding habitats.Remarkable differences found between malesand females of each species confirm that during gestation andlactation, females undergo disintoxication by passing much of their total burden of CHs to their young.
