补充资料:城市环境污染监测
城市环境污染监测
类的社会环境因素。2.监测项目复杂。包括工业三废排放、交通排放的化学污染,高大建筑物引起的日照和电波障碍导致的物理污染。3.要长时间连续跟踪监测。4.要求监测手段多样性。不单要有物理测定、化学测定,有时还要配合生物测定。城市污染监测主要有四方面内容:1.物理指标的测定,包括噪声、振动、电磁波、热能、放射性等水平的监测。2.化学指标的测定,包括各种化学物质在空气、水体、土壤和生物体内水平的监测。3.生态系统监测,主要监测由于人类生产和生活引起的生态系统的变化,如二氧化碳和氟氯烃的过量排放引起的温室效应和臭氧层的破坏等。4.对长期积累的监测资料进行系统分析。进行城市环境监测的主要原则为:1.要有明确的监测目的;2.要有完整合理的监测计划;3.要有正确的监测方法、监测手段和质量保证措施;4.要有分析评价监测数据的科学方法。城市环境污染监测根据任务性质的不同有科研性监测、事故性监测、常规监测、仲裁监测等多种目的监测,它是进行城市环境管理和环境科研以及环境规划的基础。城市环境监测必将随着环境保护事业的发展而日趋完善。【城市环境污染监测】依据国家颁布的排放标准和卫生标准,对影响人类和生物生存和发展的城市环境质t状况进行监视性测定,对环境中含有的有害因素的数t及其影响范围进行检测,并对污染源进行监督的工作。城市中工、商业发达,政治活动频繁,人口集中,因而由于人类生产、生活活动排放的污物较多,这决定了城市污染监测的特性:1.监测内容庞大。不仅包括自然环境,如水体、大气等污染,还包括诸如嗓声、地面沉降、电波干扰之
