Urban Air Contamination In Brazil

In Australia 3000 deaths each year are caused by air pollution. Scientific research shows that over the last decade, air pollution is increasing due to overpopulated areas, and burning of fossil fuels in both energy plants, and vehicles. The initiative- ‘conserve energy future’ states-“inhaling polluted air takes away at least 1-2 years of a typical human’s life”.

Pollution continues to pose an enormous threat to residents of urban cities worldwide. In the August 2008 Monthly Update, it is stated that approximately 800,000 deaths each year can be attributed to outdoor air pollution, making pollution the single most harmful environmental hazard to human health in urban areas (Kallman). The fact that pollution kills hundreds of thousands of people each year alone portrays just how dangerous living in these conditions can be. Kallman writes about a study which proves an increase in upper respiratory diseases, cardiovascular mortality, respiratory mortality, and low birth weights when exposed to air pollutants (August 2008: Monthly Update). These can be very serious diseases and complications which, when contracted, can lead to death or very serious illnesses. There

World War I significantly influenced the modern world in which all humanity subsists. The United States of America was altered internally and externally by the Great War. Shadowing World War I America was distinguished as a supreme nation holding great power; subsequently the nation would be redefined politically, economically, and socially.

Yes, I agree with your post. I just would like to comment regarding the air pollution. The pollution in the air causes quite a few problems in the nineteenth century such as: the trees started to dye, the smoke irritated the nose and they was prone to other diseases. “The poor immigrants and blacks who lived and worked in crowed inner cities were especially prone to diphtheria and pneumonia” (Merchant, 120). The air pollution was mainly in the towns where there was coal burning

In 1992, the United Nations described Mexico City’s air as the most polluted on the planet. Six years later,earned its name “the most dangerous city in the world for children”. But despite more than a decade of dangerous pollution, a haze hangs over the city most days, obscuring the surrounding snow-capped mountains and endangering the health of its inhabitants. Geography interferes with human population to produce a poisonous scenario. Located in the crater of an extinct volcano, Mexico City is about 2,240 metres above sea level. The lower levels of oxygen at this altitude cause incomplete fuel in engines and higher types of compounds. Intense sunlight turns these into abnormal smog levels. Overall, the smog prevents the sun from heating up atmosphere enough to penetrate the ozone layer above the city. Solving this problem has been a priority for Mexico. Recent efforts to lower levels of emissions have been successful. In the 1990s, the government introduced air quality improvement programs that included a rotating one-weekday ban on car use. On days of high pollution, the ban extends to every second day. In addition to this program, car owners must have their vehicles certified every six months.

In this paper, I will be outlining the costs and benefits of social and technological fixes, and then I will be assessing the use of social and technological fixes of air pollution through the use of automobiles.

Air pollution is one of the biggest causes of environmental impact in any region. Therefore, air quality needs to be evaluated and maintained for avoiding health hazards. According to WHO, air pollution claims more than 2.4 million lives each year (WHO, 2002). Cities have to face more air pollution problems as compared to

The consequences of air pollution have been detrimental for the economy, and the continued degradation of air quality will further increase the negative impact of health. In today’s society, no one is aware of the cost of air pollution, however expert’s analysis concluded that the cost for air pollution may be far worse than previously estimated. “Since the early 2000s, emissions from sources

“Automobiles have a large impact on the quality of our environment and public health. Automobile use affects virtually every aspect of environmental quality - including noise levels, air quality, water pollution, and urban sprawl. Ninety percent of the environmental impact of automobiles occurs through the operation of the cars: about 10 percent from the production, raw materials and disposal of

To embark, the athletes are greatly affected by the air pollution in Rio. They were told to not drink water that was from the Guanabara Bay because it is contaminated, but they can not avoid the air. The air analysis done by Reuters and scientists in Brazil found high level of particulate matter of a PM2.5, while the highest recorded in the Olympics Stadium was at 65 PM2.5. The study done

Air pollution in Brazil has increased, mainly as a result of the rapid urbanization and industrial development taking place in most of the city

The amount of factories and industries has grown immensely through the previous years which has resulted in an expansion in the consumption of petroleum products. Innovation has begun to increase and has promoted the expansion of the production of cars. As stated by the Air Quality Research Center, “Air pollution is one of the most dangerous environmental problems, causing many adverse health effects and responsible for 50,000 deaths in the U.S. each year” (Air Pollution and Health – Air Quality Research Center.). The smog and

Air, is one of the most substantial source to mankind and our planet. While it exists, so does everything else along. However, in today’s epidemic, there has been certain factors that have increased in understanding whether the air we breathe today is healthy or not? Is it doing more harm than we thought? In other words, the health risks against air pollution have risen in the past few decades; all from what you may ask? Well, it could be for various factors and evaluations; either environmental or materialistic. Pollution is a major public health crisis in the world. (Friis, 2012). This is one of the conflicts that contribute to various aspects of an individual’s life, whether they may realize it or not. In this paper will include the sources that cause pollution with the effects it cause as well as policies on the regulation of air pollution.

Motor vehicle emissions remain the highest source of air pollution in Australian major cities with Sydney holding the record for the worst air quality in Australia. Although Sydney has comparatively better levels of air quality compared to other major cities in the world, air pollution is still a major environmental and health issue. The NSW Department of Environment and Climate Change have put the cost of this issue to human health at more than $4.7 billion each year in the greater metropolitan area. Health experts have also estimated that air pollution cause up to 1400 deaths per year in Sydney alone, and up to 2000 hospital admissions for respiratory and cardiovascular illnesses. In a 2004 statement by the CSIRO, the mortality rate due to air pollution in Australia (approximately 2,400 deaths each year at the time) was higher than the road toll (approximately 1,700 deaths each year at the time), and these estimates have only risen in recent years as medical science gains a better understanding of the link between air pollution, health problems, and the significant cost to our economy.

One of the most important problems that Madrid is facing is the air pollution due to emissions from the conventional vehicles and other sources. There are some protocols that are applied in case it is reached the maximum limit of CO2 and NOx concentration. However, that is not enough because it does not stop the contamination. In order to solve the problem, it is needed an economic and energy restructuration of the city. Some of the ideal characteristics for a city of the future are going to be described as follows.
