Commercial air transportation generates numerous direct, indirect, and induced benefits and can be a driver of economic growth (Button and Yuan, 2013; Green, 2007). However, the development of the nationwide airspace structure and the associated infrastructure has driven the need for assessments of the external costs of aviation. Safety, congestion, local air pollution, water degradation, and climate change are all important and potentially adverse considerations. Aviation noise is one such negative
the word pollution, they might think of factories producing harmful gas and cars creating exhaust. The truth is, it is so much more than that. While car pollution and exhaust is a big problem, there are so many more types of pollution many people probably have never heard of. Even when we exhale, we cause dangerous gases to be released into the atmosphere. This is called carbon dioxide and can be one of the most dangerous gases to our species and animals around us. Here’s why: Pollution is and has
ABSTRACT Air pollution are one of the most important environmental issues world wide . In this study pollutant CO, BC, PM were measured to determine the ambient air quality in Noida, U.P.. The average concentration of CO, BC,PM10,PM2.5 ,PM0.1 were found to be 1.54ppm, 25107.82 ug/mᶾ, 1737.16 ug/mᶾ, 341.45 ug/mᶾ, 260.19 ug/mᶾ in respectively institutional site , 3.86ppm, 16829.65 ug/mᶾ , 632.68 ug/mᶾ , 299.38 ug/mᶾ , 247.16 ug/mᶾ in respectively arterial site ,7.77ppm , 23112.56 ug/mᶾ, 466
B. Restaurants: Everyone has heard of air pollution coming from smokestacks and automobiles; however, most do not know that the smoke and fumes exhausted from your local neighborhood restaurant can be detrimental to your health as well. According to the EPA (Environmental Protection Agency) as early as 1991, exhaust from nearby buildings, such as restaurants, can enter your home and create a higher level of indoor air pollution. Many restaurants use grills and char broilers to cook their food, which
the recent discussion about global warming and pollution, people want to know what in the environment is putting their lives at risk. Today, the amount of energy and fossil fuels burned in modern day Earth has made air pollution become a major concerning pathogen from the environment. Air pollution, or pollution in general, is a generally new topic of research for many. However, there has been enough evidence and consistency in researches on air pollution to show that it has significantly life-threatening
environmental contaminants, air pollution is receiving greater attention and recently the relationship between prenatal exposures and compromised lung development and function is becoming more evident. This means that, even before the first breath, the lungs are already affected. Exposures to air pollutants are ubiquitous and affects millions of people worldwide. Recently, WHO released a report that shows that 80% of the population living in cities are exposed to air pollutants levels that exceed
Air pollution is said to be one of the major environmental problems that is present in both developed and developing countries. Nations have been trying to reduce the amount of the air pollutants; nevertheless, it is an inevitable problem in a world where people are highly dependent on industries. Air pollution is the contamination of air by smoke and harmful gases, mainly oxides of carbon, sulfur, and nitrogen. This takes a huge toll on human health, and the surrounding environment
Introduction Air pollution can be understood as the phenomenon that occurs when gases, dust particles fume/smoke or odor are introduced into the atmosphere such that it is harmful to humans, animals and plants (eSchoolToday, 2015). Those things that pollute the air are known as pollutants, for example; nitrogen oxides, carbon monoxides, hydrocarbons, sulpur oxides, etc. These pollutants can be classified as primary pollutants, which are gases or particles introduced into the air to make it unclean
Every living thing need air to breath, right? Then why do people pollute the air with with so many hydrocarbons and other toxins everyday?Air pollution is a well known subject but the problem seems to get worse. An example of this can be seen in a data collection by the EPA (Environmental Protection Agency): “Emissions of air pollutants continue to play an important role in a number of air quality issues. In 2016, about 78 million tons of pollution were emitted into the atmosphere in the United
measures that prevent pollution and ecological degradation ....” As per Section 24 of the South African Constitution, this lays the foundation for an individual’s human right that everyone is entitled to. 2 WHAT IS AIR POLLUTION? The sufficient concentration of substances present in the air for a sufficient amount of time that is harmful to human, animal, plant, or to property, or which reasonably affects the comfortable enjoyment of life and property can be regarded as air pollution (Cheremisinoff,
