应用CALUX法测定四川省废弃物焚烧厂飞灰及周边土壤中二噁英类物质含量

采集四川省生活废弃物焚烧炉飞灰和企业周边土壤样品10个,应用CALUX生物检测法测定了样品中二噁英类物质的毒性当量。与国内外文献报道值进行比较,结果表明两家废弃物焚烧企业飞灰中二噁英类物质的毒性当量水平较低;企业上风向3 000m土壤背景样品受周围人类活动影响,二噁英类毒性当量值与其它省份土壤背景值相比较高;企业周边1 200m范围内土壤中二噁英类物质的毒性当量值介于9.4~12.16 ng-TEQ/kg,低于国外除农业用地外的其他规划用地标准,与国内上海、杭州焚烧企业周边土壤样品中二噁英类毒性当量一致,但高于广东、江苏和天津焚烧企业周边土壤中二噁英毒性当量值。检测结果为四川省持久性有机污染物的污染防治提供了数据支持,并填补了国内四川省废弃物焚烧企业周边土壤中二噁英含量的数据空白。

危险废物焚烧中污染防治的过程控制

危险废物焚烧污染防治的重点在烟气的处理上,一般情况下烟气处理的能力是固定不变的,但焚烧系统焚烧的危险废物是千差万别的,产生的烟气中污染物浓度也是变化很大的,如果不优化废料配给等系统,很难保证烟气经处理后能达标排放。因此危险废物焚烧中污染防治是一个系统工程,需要焚烧过程中各个环节优化控制。本文以一德国企业的危险废物焚烧设备为例,详细论述在编写焚烧日计划、焚烧系统、热能利用系统和烟气处理系统等各环节的污染防治的过程控制。

BAN waste, environmental justice and citizen participation in policy setting

It is widely acknowledged that the poorest sections of society bear a disproportionate burden of poor environmental quality, including toxicity and pollution. The struggles to address environmental injustice instigated at grassroots level also place the burden of righting the injustice on those who often have the least resources in terms of time, money and access to decision makers. The unfolding story of BAN Waste's sophisticated challenge to the proposed building of a replacement incinerator in a working-class area of Newcastle demonstrates many of the issues and stages common to struggles for environmental justice. The struggle became proactive and built wider alliances and a broad coalition across the city for change. The eventual success in preventing the incinerator being built and in producing a superior waste strategy counters the popular belief that environmental concerns are predominantly those of the middle class.     

A generic comparison of the airborne risks to human health from landfill and incinerator disposal of municipal solid waste

A comparison of the potential risks to human health from municipal solid waste (MSW) incineration and landfill on a generic basis is attempted. For this purpose a 'worst case' approach is adopted and a number of assumptions regarding the size and activities of each waste disposal method are made. The airborne pollutants measured for an incinerator are different from those for a landfill with or without gas collection. However, based on the available information it appears that as far as airborne pollution is concerned, landfill sites without gas collection pose a potentially higher generic risk to human health than MSW incinerators performing to Environmental Agency (UK) standards. This analysis cannot be used to replace specific evaluations for a particular incinerator or a landfill site because local conditions can have a very large impact on the magnitude of risks involved.

Progress towards Environmental Justice: A Five-year Perspective of Toxicity,Race and Poverty in Michigan, 1990-1995 1

Much present research on the relationship between socio-economic factors and the siting of sources of environmental pollution has focused primarily on race and income. Using census data, timed-based data from multiple sources of pollution, and rates of cancers and low birth weight in the State of Michigan by zip code, we present a multivariate model that can distinguish the effects of race, income and other land use characteristics on: (1) the location of different sources of pollution; (2) progress toward clean-up of contaminated waste; and (3) how pollution is associated with measures of public health.
