from skin cancer. But ozone is also the main ingredient of smog‚ and causes serious health effects and forest and crop damage in the lower atmosphere. Ozone is formed through the chemical reaction of volatile organic compounds and nitrogen dioxide‚ in the atmosphere‚ in the presence of sunlight. This reaction is called a photochemical reaction‚ because sunlight is required. The product is known as smog. The notorious brownish color of smog is due to nitrogen dioxide of the mixture.

one example of air pollution which lead to environment degraded in London. London in SE England had the reputation of one of the most polluted cities in Europe in the 1950s. Air pollution had reached such a serious stage that it caused the London Smog in 1952 that caused 4000 deaths and a host of other related ailments among the Londoners. One of the main causes of the serious air pollution was the burning of fossil fuels by the many manufacturing industries producing iron and steel‚ automobiles

Visibility was limited to only three blocks and residents suffered from smarting eyes‚ respiratory discomfort‚ nausea‚ and vomiting… Smog events continued to plague Los Angeles throughout the 1940s.” “The City of Los Angeles began its air pollution control program in 1945‚ establishing the Bureau

But how many of us realize that this has become irrelevant in today’s world‚ because the quality of air in our cities is anything but fresh. The moment you step out of the house and are on the road you can actually see the air getting polluted; a cloud of smoke from the exhaust of a bus‚ car‚ or a scooter; smoke billowing from a factory chimney‚ flyash generated by thermal power plants‚ and speeding cars causing dust

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 pollutants that make up photochemical smog. Some pollutants may be both primary and secondary: that is‚ they are both emitted directly and formed from other primary pollutants. About 4 percent of deaths in the United States can be attributed to air pollution‚ according to the Environmental

ability to prevent air pollution. Air pollution is the presence in the atmosphere of harmful gases‚ liquids‚ or solids. Air pollution‚ known as smoke pollution for many years‚ resulted from coal combustion (Hodges 526). Smog has been a problem in coal-burning areas for several centuries. Smog finally decreased when coal combustion was replaced by oil and gas combustion. Air pollution is caused by a number of different types of pollutants. The first type‚ particulate matter‚ consists of solid and liquid

BENEFITS OF FOREST RESOURCES A forest‚ also referred to as a wood or the woods‚ is an area with a high density of trees. As with cities‚ depending on various cultural definitions‚ what is considered a forest may vary significantly in size and have different classifications according to how and of what the forest is composed. A forest is usually an area filled with trees but any tall densely packed area of vegetation may be considered a forest‚ even underwater vegetation such as kelp forests‚ or

THE BRUTAL HAZE Haze consists of tiny elements which occurs naturally or is a result of daily human activities. Smog produced by factories and automobiles as well as fire smoke is the main contributing factors of the existence of haze. The one of the main cause that touches off haze is the industries who evil mind construct the smog that had over the standard and the smog seriously influence the air become air pollution. The components that make up haze are carbon monoxide‚ sulphur dioxide‚

Air Pollution 20.000 liters of air is what we breathe on a daily basis. Air is something most people take for granted‚ you don’t see it around you and breathing goes automatically. But every time we inhale we risk inhaling dangerous chemicals which found their way in our air. Air pollution is the presence of dangerous chemicals in the air that we breathe. It is a change in the air which influences humans health and organism on the planet. Many think that `gases’’ pollute the air‚ those gases

depleting life in freshwater lakes. The problem of acid rain originated during the Industrial Revolution‚ and has been growing ever since. The severity of its effects has long been recognized in local settings‚ exemplified by the spells of acid smog in heavily industrialized areas. The widespread destructiveness of acid rain‚ however‚ has become evident only in recent decades. One large area that has been studied extensively is northern Europe. In 1984‚ for example‚ environmental reports indicated
