Fine particles are more dangerous than coarse particles. Apart from the size of the particles, other specific physical, chemical, and biological characteristics that can influence harmful health effects include the presence of metals, PAHs, other organic components, or certain toxins. When particulate matter is combined with other air pollutants, the individual effects of each pollutant is accumulated. In certain cases, especially for combinations of particulate matter with ozone or allergens, effects were shown to be even greater than the sum of the individual effects. When particulate matter interacts with gases, this interaction changes its composition and, therefore, its effects.
The first type of pollution is air pollution. According to United States Environmental Protection Agency (as cited in Vallero, 2008, p. 3), air pollution is the presence of contaminants or pollutant substances in the air that interfere with human health or welfare, or produce other harmful environmental effects. Air pollution always consists of a whole range of pollutants, gaseous and particular alike. Common pollutants which are major public health concern include particulate mass and some gases like ozone, nitrogen oxides, sulphur oxide, and carbon monoxide. The sources of these pollutants include household combustion devices, motor vehicles, industrial facilities, forest fires and pesticides.
A ground-level ozone known as Smog formed in polluted regions. This is due to the increased heat and warmer atmosphere created by air pollution and global warming. This type of smog can irritate the lungs and trigger attacks in individuals who have asthma. Long term exposure to the ozone gases are associated with decrease in lung function. (Yeung.
The chemicals used in the textile, glass, medicine and many other industies meant that products could be manufactured on a much larger scale, greater than ever before thought possible.Not only was the scale much bigger, the materials were less expensive, this meant that the public had access to products once much too expensive to purchase, different coloured clothing for example, and medicines. There was however one major downside to the use of these chemicals on such a large scale, pollution. This was a huge problem in the mid nineteenth century, especially in densely populated cities.The air pollution generated by the Leblanc process began to concern many of the people who had to live in the presence of the big industrial factories responsible for emitting the unwanted fumes. According to one of the most important figures in the chemical industry during the industrial revolution James Muspratt, the fumes given off from the process were so dense that the visibility in the area was less than ninety meters.

Classical buildings on the Acropolis in Athens show extensive decay or chemical weathering that accelerated in the 20th century as a result of air pollution in the form of with SO2 and NOx emissions, and other acid producing substances in the atmosphere. This problem has escalated to such an extent that buildings require restorations, protective coatings on statues, and other monuments have to be replaced quite frequently at very expensive costs per year. Stone decays about twice as fast in cities than in rural areas. This damage is mainly as a result of acid rain, humidity in the atmosphere, as well as from corrosive groundwater. This means that measuring the rates of stone decay can tell us something about the changes in the pH of rain and groundwater in different regions and years.
Air pollution is the result of the emission of chemicals, particulate matter, and biologic material into the atmosphere then caused adverse effect on environment and health. Major air pollutants that threatening human health are carbon monoxide, nitrogen oxide, ozone, chemical vapors, and particulate matter. Air pollution is an important risk factor for cardiovascular health, therefore In this review article, we discuss air-polluted particle and the adverse effects of them on cardiovascular disease. Introduction: With advances in technology, air pollution has also increased. Air pollution caused mortality and cardiovascular disease in population [1-3].
There are many problems that threatens society and one problem in particular, air pollution is a problem that threatens everyone. Air pollution is the contamination of air with pollutants that are harmful to humans, animals, and the environment. It began to be a problem when humans discovered the uses of fire and then the amount of air pollution exponentially grew after the industrial revolution, and is still a problem even today. The largest causes of air pollution are from human activities such as burning of fossil fuels and gas emissions from manufacturing plants. There are ways that ordinary people can help contribute to prevent air pollution and or else face the dangerous consequences of polluted air.
Air pollution supports global warming which is a dangerous problem that is getting worse. Besides the effects that offshore drilling has on wildlife it also immensely affects global warming and the gases that are released from the rigs goes into the air that we breathe. Lombardo states, “No matter what personal stance on global warming may be, there is no denying that an offshore drilling rig produces an enormous amount of air pollution that can affect the shorelines” (n. pag.). Not only does do offshore drilling rigs pollute the air but they also pollute the oceans and create a deadly environment for marine life and reefs.
When the city development, urban heat island, effect becomes more and more severe. Urban Heart Island means that refers to the city due to a large number of artificial fever, buildings and roads and other high-heat storage and green space reduction and other factors, resulting in the city "high temperature". Cities are the most obvious places where the global environmental change and health problems cross each other. The available evidence confirms that global climate change is leading to more and more intense extreme heat / cold events. Interactions between extreme hot / cold events and pollution lead to increased morbidity and mortality in urban-susceptible populations.
INTRO: Air pollution is a worldwide human health risk that affects people of all social classes. The most polluted cities can be found in developed countries such as the United States, China, and the UK. Although air pollution can be the result of natural phenomena such as volcanoes and storms, much of today’s issues stem from anthropogenic i.e. human, causes. Houston, Texas is one of the largest cities in the United States and, unfortunately, the quality of their atmosphere reflects the city’s expansive area, many shipping ports, chemical plants, and high traffic.
Natural gas can be extremely dangerous when spilled or leaked. Natural gas is highly flammable and can catch fire easily, when a spark or flame is introduced to this gas it will cause a very dangerous fire explosion. Because natural gas is full of carbon it can cause Carbon Monoxide. Carbon Monoxide is very important, it causes headaches fuzzy vision, and fatigue. When inhaled it stops the oxygen that gets to the brain and can be life threatening.
