电场耦合高效液相色谱柱改善极性芳烃分离的研究

从燃烧的煤和油中排放出来的极性污染物,包含有多种含氮、氧和硫的极性多环芳烃(PAH),这些极性组分比非极性组分常具有更强的致癌和致突变性。目前,正相高效液相色谱(NP-HPLC)常被用来分离分析这类极性组分。 但是,要提高这些极性组分分离的选择性,现大多采用梯度洗脱的方法。也就是改变流动相极性的方法。本文介绍了一种高压电场耦合色谱柱的新方法。这种技术除了具     

流域水质监测站对江河重大污染事故的应急监测措施的研究

流域水质监测站对发生在江河中的重大水质污染事故中承担着前哨的重要作用.因此,建立起江河重大污染事故的应急监测体系已迫在眉睫.本文结合多年来松花江水质监测的实际工作,对环境水质监测部门开展重大污染事故应惠监测措施研究的必要性、应急监测工作必需的配置、预警监测断面在应急监测中的功能与作用等进行了较全面的论述.指出,应加大江河水环境监测的投入,切实加强水环境应急监测工作,尽快建成主要江河应急防控体系,提高江河重大污染事件的预警预测、监测、处置、后期评估等方面能力与水平.

Residents' preparedness and response to the Kalamazoo Tornado

A survey was conducted of individuals residing directly in the path of the tornado that hit Kalamazoo, Michigan, on 13th May 1980. The residents' tornado preparedness and response were examined in an effort to evaluate the city's emergency warning system. The system was adequate for people on the east side of the city and lacking for west side residents. Other factors pertaining to the storm event and human response were also evaluated.

Accidents and risk control

A framework for transformation of knowledge and experience from risk analysis to emergency education is presented. An accident model was developed built on the concept “uncontrolled flow of energy (UFOE)”, where essential elements are the state, location and movement of the energy. A UFOE can be considered as the driving force of an accident, e.g. an explosion, a release of heavy gases. A domain model has been developed for representing emergencies occurring in society. A domain is a group of activities with allied goals and elements, and the domain model uses three main categories: status, context and objectives. Ten specific domains have been investigated including process plant, energy production and distribution, natural disasters and different sorts of transport. Totally 25 accident cases were consulted and information was extracted for filling into the schematic representations with two to four cases pr. specific domain.
