amendments of 1990 regulate the emissions of sulfur dioxide starting in 1995. The intention of this legislation is to control the formation of acid rain. Between 1995 and 1999‚ the Bowen plant will receive allowances to emit 254‚580 tons of sulfur dioxide per year. Starting in 2000‚ the Bowen plant will receive allowances to emit 122‚198 tons of sulfur dioxide per year. To comply with the law‚ the Bowen plant will either have to reduce its emissions of sulfur dioxide to below the amount for which it has

or natural occurrences can cause acid rain. For example‚ when a volcano erupts‚ it releases sulfur dioxide as one of the main components‚ which can enter the water and cause it to become acidic. However‚ the primary source of acid rain is the acidic compounds released by atmosphere pollution. Industrial processes like factories and motors like cars release sulfur dioxide (SO2) and nitrogen oxide and dioxide (NO2 or NO3‚ commonly written as NOx)‚ which are both strong acids when added to water. As

This paper argues on both theoretical and empirical grounds that‚ beyond a certain point‚ there is an unavoidable conflictbetween economic development (generally taken to mean ’materialeconomic growth’) and environmental protection. Think for a moment of natural forests‚ grasslands‚ marine estuaries‚ salt marshes‚ and coral reefs; and of arable soils‚ aquifers‚ mineraldeposits‚ petroleum‚ and coal. These are all forms of ’natural capital’ that represent highly-ordered self-producing ecosystemsor

Atmospheric Issues SCI/275 For several years‚ we have been aware of the harms we produce to the environment‚ and yet we keep on creating them. Some people are more familiar than others about these harms. However‚ it seems as if there is no concern since change is happening slowly. Around the globe similar harms exist. Some are even more advanced in some places. We can clearly see the consequences of these harms. They are drastically disturbing our environment. The sufferers from these events
Premium Coal Oxygen Acid rain
Air pollution is one of the most common outcomes of the combustion of fossil fuels. A common air pollutant that is released is sulphur dioxide and nitrogen oxides. This is because when coal and fuels obtained from crude oil are burned‚ sulpur and nitrogen is released into the atmosphere‚ which is eventually joint with the oxygen in the air to produce sulfur dioxide and nitrogen oxide. When these gases are emitted in sufficient quantities‚ it reacts with the water and oxygen in the atmosphere to produce

Carmen What’s the acid rain? Acid rain is a rain or any other form of precipitaton that is unusually acidic. What causes acid rain? Acid rain is caused by the burning of fossil fuels. Burning oil‚ gas and coal in power statons releases Sulphur Dioxide into the atmosphere. Burning oil and petrol in motor vehicles puts nitrogen oxides into the atmosphere. These gases mix with water droplets in the atmosphere creatng weak solutons of nitric and sulphuric acids. When precipitaton occurs these solutons

The smoke from firecrackers contain sulfur compounds‚ heavy metals and other toxic chemicals and harmful fumes of gases such as sulfur dioxide‚ ozone etc‚. People with asthma‚ multiple chemical sensitivity and other breathing problems suffer largely due to the toxic emissions from these fireworks. Crackers are unnoticeably affecting all

Acid Rain is a type of air pollution‚ which is formed when oxides of sulfur and nitrogen combine with atmospheric moisture to yield sulfuric and nitric acids‚ which may then be carried long distances from a source before they are deposited by rain. This pollution may also take the form of snow‚ fog‚ or a dry form of precipitation. Acid rain is currently a subject of great controversy because of widespread environmental damage‚ for which it has been blamed‚ including eroding structures‚ injuring crops
