Essay on Air Pollution: Causes, Effects and Control of Air Pollution!
Decreased work performance should also be mentioned in the list of negative impacts caused by noise pollution. High levels of noise can cause inaccuracy and inattentiveness, which can result in decreased productivity and additional stress. This is a crucial point for people whose workplaces are potentially dangerous, such as construction sites or factories. A misheard order or instruction, or the lack of concentration in such workplaces can lead to severe consequences.
The various causes of air pollution are:

Eutrophication The term “eutrophic” means well-nourished; thus, “eutrophication” refers to natural or artificial addition of nutrients to bodies of water and to the effects of the added nutrients. When the effects are undesirable, eutrophication may be considered a form of pollution (National Academy of Sciences, 1969).
Essay on Air Pollution: Causes, Effects and Control of Air Pollution
Air pollution can further be classified into two sections- Visible air pollution and invisible air pollution. Another way of looking at Air pollution could be any substance that holds the potential to hinder the atmosphere or the well being of the living beings surviving in it. The sustainment of all things living is due to a combination of gases that collectively form the atmosphere; the imbalance caused by the increase or decrease of the percentage of these gases can be harmful for survival.

Information about the types, causes, and effects of water pollution and what we can do to solve the problem.Further along in the airway, within the lung, the bronchi continue to divide into ever-smaller (narrower) tubes, much like the branches of a tree. (Hence, the term .) The walls of the bronchi contain muscles that can cause the airway to expand (widen) or contract (narrow). For example, during , the airway expands to increase airflow (ventilation). Conversely, when exposed to polluted or very air, the airway contracts to protect the downstream tissues from injury. The smaller branches of the bronchial tree, called , also contain muscle, but they lack cartilage. Notice in Figure 1 that the very smallest bronchioles (respiratory bronchioles) connect directly to tiny air sacs in the lung, called alveoli. Figure 2 shows a microscopic section of a normal bronchial wall.
What is noise pollution and how can we fight it - read about this in our free cause and effect essay sample. Use big collection of examples to write your own one.In this picture, you can see that the bronchial wall contains cartilage and muscle, as described above. Also, note that different types of cells make up the lining (epithelium) of the bronchi (as well as of the trachea and bronchioles). One type of cell is called a goblet cell because of its shape. The goblet cells produce mucus, which lubricates the airways and traps inhaled foreign material (e.g., bacteria, , and pollutants). Other cells in the epithelium are called ciliated cells, which are discussed in the next paragraph. Beneath the surface of the airway, the goblet cells and other epithelial cells are clustered into structures called bronchial glands. These glands secrete additional mucus and other lubricating fluids.
