Sulfur dioxide is an intermediate in the production of sulfuric acid, being converted to sulfur trioxide, and then to oleum, which is made into sulfuric acid. Sulfur dioxide for this purpose is made when sulfur combines with oxygen. The method of converting sulfur dioxide to sulfuric acid is called the contact process. Several million tons are ...
The overall goal of the Acid Rain Program established by the Act [111] is to achieve significant environmental and public health benefits through reductions in emissions of sulfur dioxide (SO 2) and nitrogen oxides (NO x), the primary causes of acid rain. To achieve this goal at the lowest cost to society, the program employs both regulatory ...
The National Emissions Inventory in the U.S. [24] and the Air Pollutant Emission Inventory (APEI) in Canada [3] [10] [25] compile annual emissions of air pollutants that contribute to smog, acid rain, greenhouse gases and diminished air quality including particulate matter (PM), sulphur oxides (SO x), nitrogen oxides (NO x), cadmium, lead, mercury, and persistent organic pollutants (POPs) such ...
The most common sources of air pollution include particulates and ozone (often from burning fossil fuels), [122] nitrogen dioxide, and sulfur dioxide. Children aged less than five years who live in developing countries are the most vulnerable population to death attributable to indoor and outdoor air pollution.
Yokkaichi asthma (四日市ぜんそく, Yokkaichi zensoku) refers to cases of chronic obstructive pulmonary disease, chronic bronchitis, pulmonary emphysema, and bronchial asthma in humans and various environmental changes usually attributed to sulfur dioxide (SO 2) emissions which appeared as smog over the city of Yokkaichi in Mie Prefecture, Japan between 1960 and 1972, though other SO x ...
It is possible to scrub sulfur dioxide by using a cold solution of sodium sulfite; this forms a sodium hydrogen sulfite solution. By heating this solution it is possible to reverse the reaction to form sulfur dioxide and the sodium sulfite solution. Since the sodium sulfite solution is not consumed, it is called a regenerative treatment.
The environmental factors of the coal industry are not only impacting air pollution, water management and land use but also is causing severe health effects by the burning of the coal. Air pollution is increasing in numbers of toxins such as mercury, lead, sulfur dioxide, nitrogen oxides and other heavy metals. [93]
Petroleum extraction disrupts the equilibrium of earth's carbon cycle by transporting sequestered geologic carbon into the biosphere. The carbon is used by consumers in various forms and a large fraction is combusted into the atmosphere; thus creating massive amounts of the greenhouse gas, carbon dioxide, as a waste product.
