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.
Atmospheric pollution is caused by pollutants such as smoke from factories entering the atmosphere and being carried to waterways. Industrial waste can also create polluted runoff that collects in rivers and lakes. Another reason for water pollution is chemically treated sewage. This water carries harmful chemicals and high amounts of bacteria, which can potentially lead to serious diseases. Runoff from fields can contain chemical fertilizers and pesticides which can pollute
These pollutants affect humans, animals, plants and atmosphere. Their effects are indeed many and wide-ranging. The excessive levels of pollutants cause a lot of damage to human and animal health. For example air pollution reduces the lung functioning, cause irritation of mouth, throat, eyes and nose, asthma, respiratory symptoms like coughing and wheezing.Air pollutants like sulphur dioxide, oxides of nitrogen etc increases the respiratory diseases and reduces the energy level.Similarly water pollution causes many waterborne diseases like amoebiasis,hookworm,giardiasis,ascariasis and typhoid. The polluted water can damage the nervous system, liver, DNA and kidney.
Air pollution can be defined as the presence of gas, liquid or particles contained in the air until the occurrence of a change affecting life or other materials. Air pollution caused by emissions from vehicle exhaust, industrial discharge smoke or pollutants, and the use of charcoal or wood burning fire control. Air pollution can be divided into two parts: primary and secondary. The primary air pollutants began when production of sulfur monoxide and carbon monoxide resulting from incomplete combustion. This process will result in fine particles suspended in the air and give side effects on human health.
Natural causes of air pollution consist of volcanic eruptions, forest fires and other natural processes. However, these occurrences are not often seen and only contribute to a small amount of air pollution in the world. They create air pollutants such as ash and smoke which may give rise to harmful effects on the environment as well as the people. Human activity contributes to the bulk of air pollution. Outdoor air pollution can be caused by manufacturing, burning of fossil fuels, other forms of burning as well as smoking.
SUMMARY Acid rain is defined as any form precipitation that has abnormal acidic content. This phenomenon was first discovered in 1872 but didn’t gain popularity till 1980, when unchecked car, and industrial emission got worldwide interest. Acid rain is caused by natural and manmade emissions. The main culprits of acid rain are Sulfur and nitrogen oxides. When these gasses react with the water vapour (clouds) in the atmosphere, they form weak acids.
Pollutants are gases and particles that, when at high enough levels, are harmful to humans, animals, vegetation, and even the climate. Although it is common to blame pollution on human actions, it can also come from natural sources, such as volcanoes and forest fires. Additionally, pollutants enter the air from either point source (single, identifiable source) or non-point source (widespread or multiple sources). Furthermore, pollutants are categorized as primary or secondary pollutants. Primary pollutants those that are already dangerous when released directly into the atmosphere, such as with carbon monoxide, sulfur dioxide, and volatile organic compounds (VOCs).
DEFINITION Air pollution is the condition where there is a big enough quantity of contaminant from other substances in the air especially by the smoke or gases from vehicles, factories and power stations and it effect the health of people or other animals, kill the plants and disrupt other aspect of the environment. There are two types of air pollution which are outdoor air pollution and indoor air pollution. Outdoor air pollution included smog, particulates, and acid rain and greenhouse gases. When discussing about pollution, the first thing that come out in the mind is “pollution happens because of human”. Actually, the pollution not only because of human but it also happen naturally.
First, we use the raw resources that were taken from the environment to produce more complex goods. Secondly, the factories that are spread around the world cause harmful smoke that causes air pollution as well as the remnants of chemical plants that make up the great danger to the environment surroundings such as humans and animals and plants, the spectrum of serious damage caused by pollution in water
