实行二氧化硫总量控制是可持续发展的必然要求

随着现代工业的迅速发展,对煤炭燃料的需求日益增大,二氧化硫的污染有加重的趋势。二氧化硫污染不仅损害人体健康,还形成酸雨,腐蚀建筑材料,破坏生态系统,由此造成巨大的经济损失,已成为制约社会经济发展的重要因素之一。我国对二氧化硫污染问题十分重视,1998年1月国务院下达了《关于酸雨控制区和二氧化硫污染控制区有关问题的批复》,要求“两控区”到2000年排放二氧化硫的工业污染源达标排放,并实行二氧化硫总量控制;到2010年,二氧化硫排放总量控制在2000年排放水平以内。本文将对二氧化硫污染现状、总量控制政策等问题作出论…

Environmental Management of Sulfur Trioxide Emission: Impact of SO3 on Human Health

The major contributors to global acidification are sulfur oxides and nitrogen oxides emitted mostly by the burning of fossil fuels. From the scientific point of view, it is necessary to make a clear distinction between sulfur dioxide and sulfur trioxide when referring to sulfur oxides. These two air pollutants have different properties. This paper reports the following aspects: the strong effect of sulfur trioxide on local human health (a case study of asthma in Yokkaichi), the problem of corrosion caused by sulfur trioxide, the difference in analytical methods for determining sulfur dioxide concentrations and sulfur trioxide concentrations, and the difference in removal methods for sulfur dioxide and sulfur trioxide. An important initiative at the third European conference of environment ministers was that the issue of human health related to local air pollution should be given priority over that of global pollution. The declines in the emissions of sulfur dioxide and nitrogen oxides have mainly been effective in reducing acidification due to long-range transport. The reduction in sulfur trioxide may be more effective in improving local human health mentioned in the initiative.

Potential for Advanced Technology to Improve Air Quality and Human Health in Shanghai

/ Air quality in most Asian cities is poor and getting worse. It will soon become impossible to sustain population, economic, and industrial growth without severe deterioration of the atmospheric environment. This paper addresses the city of Shanghai, the air-quality problems it faces over the next 30 years, and the potential of advanced technology to alleviate these problems. Population, energy consumption, and emission profiles are developed for the city at 0.1 degrees x 0.1 degrees resolution and extrapolated from 1990 to 2020 using sector-specific economic growth factors. Within the context of the RAINS-Asia model, eight technology scenarios are examined for their effects on ambient concentrations of sulfur dioxide and sulfate and their emission control costs. Without new control measures, it is projected that the number of people exposed to sulfur dioxide concentrations in excess of guidelines established by the World Health Organization will rise from 650,000 in 1990 to more than 14 million in 2020. It is apparent that efforts to reduce emissions are likely to have significant health benefits, measured in terms of the cost of reducing the number of people exposed to concentrations in excess of the guidelines ($10-50 annually per person protected). Focusing efforts on the control of new coal-fired power plants and industrial facilities has the greatest benefit. However, none of the scenarios examined is alone capable of arresting the increases in emissions, concentrations, and population exposure. It is concluded that combinations of stringent scenarios in several sectors will be necessary to stabilize the situation, at a potential cost of $500 million annually by the year 2020.
