以锦州市重污染企业、固体废物集中堆放场地和工业区周边区域内土壤为研究对象,共采集75份具有代表性的土壤样品,对其12项重金属、多环芳烃类和多氯联苯的含量进行分析,研究典型区域周围环境的土壤污染状况。采用Rapant et al.环境风险指数法的计算结果表明,表层土壤中重金属污染具有较大的环境风险,其中属于低环境风险级别的样品占近30%,中等环境风险级别的样品占近10%。由此,针对锦州市典型区域土壤的污染状况,提出相应的污染防治对策。 相似文献

In Thailand, hazardous waste is becoming a major problem, especially toxic chemicals and heavy metal pollutants discharged from factories. The Industrial Works Department (IWD), which has full responsibility for the control of all factory pollution problems, has initiated a joint hazardous waste treatment programme for handling industrial liquid, sludge and solid hazardous wastes from all factories situated in and around Bangkok and the eastern seaboard region. Four industrial hazardous wastes treatment centres are planned. Secure landfills together with research and development centres will also be provided nearby for the ultimate disposal of the inert-salt sludges. The investment, operation and management of the centres is to be handled by private companies which can generate revenue by charging service fees directly to their customers. Since both governmental and private sectors have no experience in this field, a grant system for a pilot centre has been launched by the Government which has reduced the operating costs by providing land, treatment facilities, infrastructure and secured landfills. The first treatment centre which was officially planned in 1985 was put into operation in July 1988 at Samea Dam, Bangkhuntien District, a western suburb of Bangkok. The construction of all necessary facilities was paid for by the Government. The operation and management of the centre is handled by a private contractor, Siam Control Company (SCC) under a 5-year lease. The users will pay service fees directly to the contractor and the Government will receive a rental and royalty fee from the contractor. 相似文献

The development of regulations patterned after the United States’ requirement for maximum achievable control technology (MACT)
to control hazardous air pollutants from major industrial sources in Korea is in progress. Current management practices and
installed air pollution control devices were surveyed; emission tests and continuous emission data collected from facilities
under operation were assessed considering other MACT requirements such as reporting, report keeping requirements. Emission
sampling and air pollutant analysis were carried out at representative hazardous waste incinerators installed with wet-type
and dry-type air pollution control devices. Korean and United States Environmental Protection Agency methods were used for
sampling and analysis. The major heavy metals emitted were Zn, Ni, Pb, and Cr. The heavy metal removal efficiency of existing
air pollution control devices was greater than 99%. The average mercury removal efficiency was more than 30%. Toluene; m,p-xylene; o-xylene; benzene; dichloromethane; styrene; ethylbenzene; 1,3-dichlorobenzene; and 1,2,4-trimethylbenzene were the major volatile
organic compounds emitted. The emissions from field tests were compared, reviewed, and analyzed with respect to MACT regulations
to check applicability. Finally, draft guidelines were suggested for effective hazardous air pollutant management in Korea. 相似文献

In this paper, wood waste (RWW) recovered for heat production in Sweden was studied. Previous research has concluded that RWW contains elevated amounts of heavy metals, causing environmental problems during waste management. This study extends previous work on RWW by analysing which pollution sources cause this contamination. Using existing data on the metal contents in various materials, and the amounts of these materials in RWW, the share of the elevated amounts of metals in RWW that these materials explain was quantified. Six different materials occurring in RWW were studied and the results show that they explain from 70% to 100% of the amounts of arsenic, chromium, lead, copper and zinc in RWW. The most important materials contributing to contamination of RWW are surface-treated wood, industrial preservative-treated wood, plastic and galvanised fastening systems. These findings enable the development and evaluation of strategies aiming to decrease pollution and resource loss from handling RWW. It is argued that source separation and measures taken further downstream from the generation site, such as treatment, need to be combined to substantially decrease the amount of heavy metals in RWW. 相似文献
