Acid rain is considered precipitation in the form of rain‚ snow‚ or fog. It is not regular precipitation. It is precipitation that is polluted by acid. Emissions of sulfur dioxide and nitrogen oxide into the atmosphere cause this precipitation to become acidic. These emissions are released into the atmosphere by human activity‚ such as automobiles‚ industries‚ and electrical power plants that burn fossil fuels like coal and oil. When these gases are released‚ they mix with water vapor in the clouds

Sulfuric Acid is one of the the important chemical compounds. A Great amount of sulfur is mined all around the world and is used to produce sulfuric acid. Sulfuric acids being produced Sulfuric acid may seem like something to find in a lab‚ perhaps under the label “corrosive‚” and in some kind of tube that isn’t affected by it. But‚ in reality‚ it’s quite common‚ and is used often in the industrial business‚ for many different objects. Because of this‚ many places can often be judged upon their

they may be natural or man-made.[2] Pollutants can be classified as primary or secondary. Usually‚ primary pollutants are directly emitted from a process‚ such as ash from a volcanic eruption‚ the carbon monoxide gas from a motor vehicle exhaust or sulfur dioxide released from factories. Secondary pollutants are not emitted directly. Rather‚ they form in the air when primary pollutants react or interact. An important example of a secondary pollutant is ground level ozone — one of the many secondary

Air Pollution is one of the most worrying problems of our time. This problem surfaced during the industrial revolution. The great industrial revolution brought about many positive changes to the world; better transportation‚ cheaper products‚ and a better life. However‚ with it’s riches came the price‚ pollution. At the beginning of the industrial revolution‚ no one paid any attention to the problem of pollution. As the science‚ progressed people started to realize this problem. Air pollution

smoke emitted from vehicles and factories without particle filters such as nitrogen dioxide (reddish-brown toxic gas has a characteristic sharp‚ biting odor)‚ and sulphur dioxide (coal and petroleum often contain sulfur compounds‚ their combustion generates sulfur dioxide unless the sulfur compounds are removed before burning the fuel).

affects the world climate. Environmental issues have made a huge impact on Norway. Acid rain is one of the most serious environmental problems that Norway faces. Acid rain is caused by Sulfur Dioxide emissions. The Sulfur Dioxide emissions have decreased incredibly since the 1970’s‚ because of the UNECE Sulfur Protocols. But this has not stopped the horrible after-effects that the acid rain had caused. Much of the lands soil and surface water is extremely susceptible to acidification. This created

the many of the by-products produced during the recycling are poisonous. So lead recycling can be broadly divided into to two categories * Removal of lead * Pollution control Major pollutants in lead recycling: * Lead * Sulfur dioxide and sulfur trioxides * Carbon monoxide * Nitrogen oxides * Arsenic Impact of lead exposure: Lead poisoning is the most serious environmental health threat to children and one of the most significant contributors to occupational disease
