A story about pollution


Pollution can be defined as an undesirable change in the physical, chemical or biological aspects of air, water, and land that could be harmful to human and animal health, living conditions, industrial processes and cultural assets. Pollution can be natural or man-made. Contaminating agents are called pollution. Pollution is nothing but the products of human action. Smoke, tar or dust and household waste are some of the examples of pollution. In the agricultural sector, pollutants can be Pesticides, herbicides, fungicides and fertilizers. Primarily CO, nitrogen oxides, sulfur oxides, halogen (chlorine, bromine and iodine) are those gases that contribute to increasing pollution now in days. Types of pollution Mostly there are 3 types of dirt. Leading to 95% total pollution. Air pollution. Noise Contamination. Water pollution. Air pollution The WHO defines air pollution as the presence of atmospheric substances in such concentrations that are harmful to man and his environment. Many of these ingredients find their way into the air and these are mainly gases, which spread rapidly over vast areas. This type of pollution accounts for about 70 percent of the total pollution in the atmosphere. Source of Air Pollution Major sources of air pollution through fossil fuels, emissions from cars, industry, agricultural activities and wars. Some of these are described below. Mineral oil: Due to the burning of fossil fuels, the level of pollution increases day by day. The burning of wood, coal, and other fossil fuels causes air pollution by the release of carbon dioxide, carbon sulfur dioxide, and other harmful gases into the atmosphere. Vehicle Emissions: Vehicles emit more than 80 percent of global air pollution. Many harmful gases such as CO, non-combustible hydrocarbons and nitrogen oxide are emitted from cars, cars, planes etc. Industry: Industries are one of the major sources of pollution nowadays. Due to the high demand for paper, textiles, gasoline refineries and thermal energy, the level of pollution is increasing dramatically. These industries add various harmful gases such as CO, SO, NO, Hydrocarbons into the atmosphere. Effects of Air Pollution Air pollution can directly affect plants and animals. Due to air pollution the cells and tissues of plants are severely affected. Nitrogen oxides and fluorides reduce yields. Smoke and dust cover the surface of the leaf and reduce plant energy. Ozone deplets grain, fruit, and cotton crops. This air pollution affects animals in the following ways. Ozone causes dryness of the mucous membranes, changes vision, causes headaches, lung congestion and edema. SO2 causes dry mouth, sore throat, blurred vision and respiratory disturbances. Cotton dust leads to respiratory problems e.g. bronchitis and asthma. Noise Contamination Audio can be defined as unwanted / unwanted noise. So pollution is an unnecessary noise that is thrown into the atmosphere without looking at the negative effects it can have. In our country migration to cities and industries has become twin problems. Industrialized cities and towns have sprung up. The lack of urban planning has led to the mixing of residential, commercial, and industrial areas. Houses, schools and hospitals are located near factories. All industrial and cultural mansions such as cars, horns, heavy machinery and light, operation and movement, radio transmitters, advanced aircraft are now disruptive and annoying. Our ears can hear a normal conversation between 30-60 decibels. Modern chat has an audio value of 60 decibels. More than 80 decibels in decibels creates noise pollution. Noise becomes a problem over 140 decibels. Effect of Sound Pollution Persistent noise affects a man physically and mentally. Significant effects include contracted blood vessels, skin rash, muscle cramps and high blood pressure leading to confusion and dizziness. High-pitched noise emitted by industrial plants, bottle machines, overhead aircraft, over a long period of time not only disturbs but also permanently damages hearing. Offices, factories, and crowded places where noise can be heard can often show anger, headaches, fatigue and nausea. Water pollution Water is very important to life, and this common truth is known to all. It is necessary to meet our basic needs for daily life. During all these processes undesirable substances are added to the water sources too much. This converts basic chemicals into rivers and streams. That is why we need to purify water and save water for future generations. Effects of Water Pollution Water pollution can directly affect the kidneys and liver due to the content of Cadmium. The chemicals mercury, arsenic and lead are toxic and harmful to chemicals as they also affect water treatment plants e.g. Organic sulfur chemicals interfere with nitrification. Leadership impairs metabolism and leads to birth defects, anemia etc.
