论职业卫生安全管理体系标准化与我国职业卫生安全管理及其改革的一致性

职业卫生安全管理体系（ＯＨＳＭＳ）标准倡导好的管理的共同原理,将ＯＨＳＭＳ融入组织总的管理体系,与我国组织职业卫生安全（ＯＨＳ）管理的经验相容,对我国组织在市场经济体制下建立自主安全管理机制有极重要的意义。实施ＯＨＳＭＳ标准不存在经济实力的前提,且ＯＨＳ投入与组织的经济效益是一致的。这种标准化适应了我国经济体制转变时期政府安全管理职能和管理方式的变化,还与我国ＯＨＳ管理体制的改革方向相吻合。我国基本具备实施ＯＨＳＭＳ标准的法律基础。为有效实施ＯＨＳＭＳ标准化,应加强ＯＨＳ法规建设,在监察体系上实行第三方机构的认证／注册制度

Removal characteristics of trace compounds of landfill gas by activated carbon adsorption

The removal characteristics of trace compounds and moisture in raw landfill gas (LFG) were studied. The LFG from the extraction well was saturated with water and moisture was eliminated by physical methods including cyclone-type dehydrator and compressor. The moisture removal efficiency of dehydrator and compressor was above 80%. As the moisture contents of LFG decreased, the toxic compounds like aromatics and chlorinated compounds were effectively removed by using the granular activated carbon. The breakthrough time and adsorption capacity of benzene, toluene, and ethyl benzene decreased rapidly when the relative humidity is over 60%. The effect of moisture was more pronounced at lower adsorbate concentrations tested than at higher concentrations. The breakthrough curves for multi-component mixtures show displacement effects. In the course of competing adsorption, adsorbates with strong interaction force to displace weakly bounded substances. Adsorption by activated carbon is in descending order of xylene, ethylbenzene, toluene, tri or tetrachloroethylene, benzene, carbon tetrachloride and chloroform in LFG, respectively.     

Evolution of particulate regulation in China--prospects and challenges of exposure-based control

China's urban and rural populations face very serious health risks from combustion particles. Major sources of exposure to inhalable particulates include the burning solid fuels (biomass and coal) for household cooking and heating, coal-fired industrial and residential boilers, tobacco smoking, and diesel motor vehicles. China began to address particulate pollution problems over 25 years ago and has implemented a series of progressively more aggressive policies. This paper reviews the successes and limitations of past and existing policies for particulate controls, as well as the effects of China's economic reforms and energy policies on particulate exposure and pollution management. We examine the challenge of emissions reporting, required as part of both China's pollution levy system and emerging system for "total emissions control." Finally, we discuss practical steps toward exposure-based regulation of particulates, which would take advantage of the high cost-effectiveness for lifesaving of controlling particulate exposure from household and neighborhood sources relative to that of controlling exposure from industrial sources.
