Acid rain has lead to the international limitations of sulphur and nitrogen oxide. Smog is a combination of various gases (a large part of this gas is produced when fuels are burnt) with water vapor and dust. Smog forms when heat and sunlight react with these gases and fine particles in the air. Its occurrence is often liked to heavy traffic, high temperatures, and calm winds. Smog is seen as a yellowish fog over cities.
Acid rain is not always in the form of rain. It can occur as rain, snow, sleet, ice, fog, hail, etc. (U.S. Environmental Protection Agency). Even if there is a new form of precipitation, the acids could still attach and it would become acid precipitation. Sulfur gases enter the atmosphere from natural sources in both the ocean and land.
WRITTEN ASSIGNMENT UNIT 6 UNIVERSITY OF THE PEOPLE WRITTEN ASSIGNMENT UNIT 6 Introduction Air pollution come about when gaseous particles, particulate matter, smoke or odor are introduced into the earth’s atmosphere in ways that make these particles harmful to living things. This harmful condition occurs because the air becomes unclean (Doršner, 2016). Some of the main air pollutants in Ghana include Dust (particulate matter), nitrogen dioxide, and Sulphur dioxide. The causes of air pollution include burning fossil fuels, agricultural practices that pollute the environment with pesticides, fertilizers and insectidies, mining operations, and exhaust from factories and industries (Dorsner, 2016). Dust WHO (1999) defines dust as solid particles
Pollutants from urban areas may even affect the weather downwind from them. Just such a situation is described in a controversial study conducted at La Porte, Indiana, a city located about thirty miles downwind of the industries of
Acid rain enters the clouds and is carried to other countries by south - westerly prevailing winds; mainly in the northern hemisphere. As you can see on the previous, page there is a picture showing you how acid rain, travels, and affects areas. Acid rain can be cause by many things. Mainly it is - industrial emissions from factories and power plants that burn fuels such as natural gas, coal or oil; emit smoke that gives off oxides, of sulphur and nitrogen, which is one environmental cause. Another environmental cause is vehicles (e.g.
The World Health Organization (WHO) (2014) defines air pollution as the presence of a chemical, physical or biological contaminant in both indoor and outdoor environment which changes the natural state of the atmosphere. Air pollution can cause fatal health issues for human and animals such as cancer, upper respiratory tract effects, reproductive effects, environmental and ecological hazards (Environmental Protection Agency (EPA), 2013). Air pollution is majorly produced from human activities such as use of mobile vehicles, factories, refineries, power plants, etc. (EPA, 2013). EPA (2013) has a record of 187 hazardous air pollutants which include contaminants such as benzene in gasoline, perchlorethlyene released from some dry cleaning companies and methylene chloride used for production of solvent and paint stripers.
In fact, there are cities much worse than Salt Lake City for hazardous pollution levels. Many of them are in California, where there is also a lot of “bowl-like” trapping of cool air by surrounding mountain ranges. .

Warmer global temperatures affect farming, wildlife, sea levels and natural landscapes. The effects of car pollution are widespread, affecting air, soil and water quality. Nitrous oxide contributes to the depletion of the ozone layer, which shields the Earth from harmful ultraviolet radiation from the sun. Sulfur dioxide and nitrogen dioxide mix with rainwater to create acid rain, which damages crops, forests and other vegetation and buildings. Oil and fuel spills from cars and trucks seep into the soil near highways, and discarded fuel and particulates from vehicle emissions contaminate lakes, rivers and wetlands.
The principal sources of air pollution in urban areas are derived from the combustion of fossil fuels for domestic heating, for power generation, in motor vehicles, in industrial processes and in the disposal of solid wastes by incineration. These atmospheric pollutants affect human health directly through inhalation, and indirectly through such exposure routes as drinking water and food contamination. Most traditional air pollutants directly affect respiratory and cardiovascular systems. Certain groups have an even greater risk to the effects of air pollution; the elderly, the young, and those weakened by debilitating ailments such as poor nutrition, which primarily fa... ... middle of paper ... ...to these terms. Environmental organization called for a seventy-five percent reduction in ten years.
Oxidation occurs in clouds mostly above cities with heavily polluted air. These clouds contain ammonia and ozone that can catalyze the reaction. This means that the ammonia and ozone will produce more sulfuric acid fast and the ammonia and ozone will not be consumed in the reaction. Nitrogen oxides are produce from power plants and exhaust fumes from automobiles. The reactions to make nitric acid are similar to the reactions to make sulfuric acid.
