Air pollution concentrations have been rapidly increasing in the major urban areas of Brazil caused mainly by the increasing use of vehicles. Policies to control car emissions in Brazil have relied basically on mandatory emission standards and subsidies for specific cleaner technology resulting in substantial decrease of car emission rates. Nevertheless‚ taxes on car sales‚ differentiated by vehicles’ size and fuel‚ have also influenced car emission patterns. This paper analyses the compliance

Causes and Effects of Air Pollution. Earth is everybody’s home and nobody likes to live in a dirty home. Of all the changes swirling among us‚ those that affect the natural environment seems to hold the most serious implication for human life. From a long period of time‚ people have been polluting the earth surface‚ but because of earth’s own ability to absorb and purify minor quantities of pollutants‚ the problem has been minimal. It is significant

Air pollution is caused by humans. Smog and ozone layer depletion are two major causes. They are both toxics in the air that humans create and toxics that effect humans as well. Smog is caused by so many different chemicals that ranges from things like automobile exhaust to hairspray. It affects humans mainly in the circulatory and respiratory systems which are both very important and crucial to survive. Ozone layer depletion is a very serious decline of gas in the ozone layer which is bad because

severely high level of air pollution. This pollution is caused by emissions from road traffic‚ industries‚ and the energy sector. In 2005‚ over 200 cities in Ukraine exceeded the levels established by the World Bank health standards for annual concentrations of at least one pollutant. Nineteen cities exceeded health standards for three or more pollutants by at least a factor of 10.

intro Air pollution is one of the most serious environmental problems in urban areas around the world. The rapid process of urbanization and extensive energy utilization mostly due to rapid economic expansion and population growth over the past few decades has made urban air pollution a growing problem. The air contains varying levels of pollutants originating from motor vehicles‚ industry‚ housing‚ and commercial sources. In most megacities‚ such as Mexico City and Los Angeles‚ cars

Air pollution is one of the most critical environmental problems today. Every day‚ the air in the atmosphere is becoming increasingly polluted‚ and toxic for human consumption. Pollution not only harms the environment but also poses a threat to human health. According to world health organization‚ air pollution has been linked to almost seven million deaths in one out of every eight people. In fact‚ several people are developing detrimental illnesses‚ a difficulty breathing‚ lung cancer and various

Air Pollution Index (API) is the conversion of ambient respirable suspended particulates (RSP)‚ sulphur dioxide (SO2)‚ carbon monoxide (CO)‚ ozone (O3) and nitrogen dioxide (NO2) concentration measured at the air quality monitoring network to a scale of 0 to 500. The lower the level‚ the better quality of air we can breathe. If the index is above 100‚ there will be an adverse acute health effect to human. The number of days which had a record of API 100 or above keeps increasing these years‚ which
