医疗废物被列为《国家危险废物名录》的首位,处理不彻底会对水体、土壤、空气和人体造成严重危害。然而,我国对医疗废物的处理起步比较晚,和世界发达国家相比处于落后状态。目前,我国的医疗废物总量逐年增加,集中处理率低,收集、分类、贮存、运输不规范,并且缺乏有效的监管体系和运行机制,应该采取加强医疗废物源头控制、建立医疗废物监管体制、提高医疗废物处理技术和能力等措施,力争在较短的时间内彻底改变我国医疗废物处理现状。 相似文献

近几年,许多发达国家将大量的有毒有害危险废物和垃圾向发展中国家转移。伴随我国国门的开放,目前我国已成为许多国家输出危险废物的目的地,我国本已脆弱的环境又面临着发达国家的侵略,他们企图将他们无法处理的废物丢在我国。这种侵略来势之猛,频率之高.已到了必须时刻警惕的程度。为此国家环境保护局、海关总署为贯彻国际上《控制危险废物越境转移及其处置巴塞尔公约》,于1991年3月发布了《关于严格控制境外有害废物转移到我国的通知》,向境外危险废物亮出了红牌。危险废物越境转移到我国的几个特点:1.隐瞒危险废物真实情况,蒙… 相似文献

<正>针对我国医疗废物焚烧处置企业落实规范化环境管理的迫切需求,依据上海地区在医疗废物焚烧处置工作的环境管理实践经验,探讨医疗废物焚烧处置企业环境管理的基本内容,以期为我国其他地区医疗废物处置企业的环境管理工作提供借鉴。1974年在墨西哥召开的"资源利用、环境与发展战略方针"专题研讨会上首次正式提出"环境管理"概念,此次会议形成了三点共识:全人类的一切基本需要应当得到满足;要进行发展以满足基本需要,但不能超出生物圈的容许极限;协调这 相似文献

Waste legislation in the United Kingdom (UK) implements European Union (EU) Directives and Regulations. However, the term used to refer to hazardous waste generated in household or municipal situations, household hazardous waste (HHW), does not occur in UK, or EU, legislation. The EU's Hazardous Waste Directive and European Waste Catalogue are the principal legislation influencing HHW, although the waste categories described are difficult to interpret. Other legislation also have impacts on HHW definition and disposal, some of which will alter current HHW disposal practices, leading to a variety of potential consequences. This paper discusses the issues affecting the management of HHW in the UK, including the apparent absence of a HHW-specific regulatory structure. Policy and regulatory measures that influence HHW management before disposal and after disposal are considered, with particular emphasis placed on disposal to landfill. 相似文献

含汞废弃荧光灯管处理现状及分析 总被引:2,自引:0,他引:2
废弃荧光灯管中含有金属汞,属于《国家危险废物名录》中的HW29含汞废物类,随意处置会破坏环境,危害人类健康,因此必须采取合理的方法对其进行处理。综合比较后发现资源化、无害化回收金属汞是最佳的处理方法。部分发达国家通过法律和技术手段的加强实现了对废弃荧光灯管的无害化回收处理,但我国在这方面的工作尚且不足,主要存在着灯管收集难、处理成本高等问题。因此,我国需要借鉴国外的管理经验,出台有效的法规措施,同时需要不断完善处理技术和大型工程建设。在我国节能减排和环境保护形势日益严峻的大环境下,辅之以合理的管理体制和技术手段,才能实现社会效益和经济效益双赢的局面。 相似文献

危险废物对环境或者人体健康会造成有害影响,有效地预测其产量是优化管理和合理处置的重要依据。以2008~2016年成都市危险废物产生量为基础,通过数据带入和整合及综合各参数因子的影响,利用人工神经网络模型预测方法客观反映并预测成都市危废产量的变化趋势。结果表明该模型预测2017~2018年成都市危险废物年产量分别达到24.46万t和26.88万t,模拟精度偏差低。因此,人工神经网络模型可以作为一种预测危险废物产生量的工具,其预测结果可以为职能部门提供决策参考。 相似文献

按照环境无害化管理原则,严格限制危险废物越境转移活动是中国履行《控制危险废物越境转移及其处置巴塞尔公约》的重要内容。本研究通过梳理《控制危险废物越境转移及其处置巴塞尔公约》关于控制危险废物越境转移的主要规定和中国立法管理实践,全面分析了中国控制危险废物越境转移管理进展。从打击非法转移、完善法律基础、建立预警机制等方面,深入剖析了中国控制危险废物越境转移面临的形势,并从强化危险废物越境转移管控、严厉打击非法出口行为、联合海关部门加强日常监管三方面提出对策建议,以期为中国全面履行《控制危险废物越境转移及其处置巴塞尔公约》要求、控制和防范危险废物越境转移环境风险提供支撑。 相似文献

In order to meet the recycling and recovery targets set forth by the European Union's (EU) Waste and Landfill Directives, both the Irish and Czech governments’ policy on waste management is changing to meet these pressures, with major emphasis being placed upon the management of biodegradable municipal waste (BMW). In particular, the EU Landfill Directive requires reductions in the rate of BMW going to landfill to 35% of 1995 values by 2016 and 2020 for Ireland and the Czech Republic, respectively. In this paper, the strategies of how Ireland and the Czech Republic plan to meet this challenge are compared. Ireland either landfills or exports its waste for recovery, while the Czech Republic has a relatively new waste management infrastructure. While Ireland met the first target of 75% diversion of BMW from landfill by 2010 and preliminary 2012 data indicate that Ireland is on track to meet the 2013 target, the achievement of the 2016 target remains at risk. Indicators that were developed to monitor the Czech Republic's path to meeting the targets demonstrate that it did not meet the first target that was set for 2010 and will probably not meet its 2013 target either. The evaluation reports on the implementation of Waste Management Plan of Czech Republic suggest that the currently applied strategy to divert biodegradable waste from landfill is not effective enough. For both countries, the EU Waste Framework and Landfill Directives will be a significant influence and driver of change in waste management practices and governance over the coming decade. This means that both countries will not only have to invest in infrastructure to achieve the targets, but will also have to increase awareness among the public in diverting this waste at the household level. Improving environmental education is part of increased awareness as it is imperative for citizens to understand the consequences of their actions as affluence continues to grow producing increased levels of waste. 相似文献

为进一步完善我国废物焚烧标准体系,防控废物焚烧环境风险,本文对欧盟废物焚烧指令与我国焚烧标准体系进行了对比分析。欧盟废物焚烧指令分别对专用焚烧厂和协同焚烧厂从废物运输到处理处置全过程的污染物排放控制做出了相关规定,适用于危险废物和非危险废物的焚烧以及常规污染物和有毒污染物的控制。欧盟废物焚烧指令对不同规模的焚烧设施采用统一标准,以日均值和半小时均值为污染物排放限值,更客观、准确地评价了污染物排放对环境的影响。与欧盟废物焚烧指令相比,我国废物焚烧标准涉及废物联合利用处置的相关条文较少,内容不详,项目缺失。我国烟尘、HCl的排放限值均在欧盟标准限值6倍以上,SO2的排放限值是欧盟标准的4~8倍。除CO、NOx的排放限值外,其他污染物排放限值也明显高于欧盟标准限值。我国采用抽样监测方法,监测结果可能在日常排放值的95%置信区间外,不具备代表性。我国可借鉴欧盟废物焚烧指令的成果制定协同焚烧标准,并严格污染物排放限值,考虑采用日均值或半小时均值的评价方法,提高我国废物焚烧标准的精确性和可执行性。 相似文献

/ Animal burrowing is critical to the formation of soils and contributes to the interface between geological materials and organic life. It also influences the management of hazardous materials at nuclear waste facilities and elsewhere. For example, residues and waste products from the production of nuclear weapons are released onto the ground surface and within engineered burial structures. Soil bioturbation has exposed radionuclides and other hazardous materials to wind and rain, thereby risking inhalation and injury to humans and wildlife on and off site. Soil bioturbation can expand soil depths and spatial distributions of the source term of hazardous waste, potentially increasing chronic exposures to wildlife and humans over the long term. Ample evidence indicates that some of the large quantities of hazardous materials around the world have been released from soil repositories, where they have also contaminated and harmed biota. Key burrowing parameters influencing these outcomes include the catalog of resident species, and their abundance, typical burrow volumes (void space created by soil displacement), burrow depth profiles, maximum depth of excavation, constituents and structural qualities of excavated soil mounds, and proportion of the ground covered by excavated soil. Other important parameters include rate of mound construction, depth of den chambers, and volume of burrow backfill. Soil bioturbation compromised the integrity of some hazardous waste management systems using soil, but the environmental impact remains largely unknown. Designers and operators of waste management facilities, as well as risk assessors, need to understand how burrowing animals influence hazardous waste storage.KEY WORDS: Burrowing; Environmental impact; Radioactivity; Risk; Soil bioturbation; Hazardous waste 相似文献
