pollution level

Pollution levels: comprehensive analysis

1. The basics of environmental pollution

Environmental pollution is the introduction of pollutants or energy into the environment, leading to adverse changes. These changes can be physical, chemical or biological, and they have a negative effect on ecosystems, human health and well -being. Understanding various aspects of pollution is necessary for the development of effective strategies to mitigate its consequences and protect the environment.

1.1. Types of pollution

Pollution is classified by the environment that it affects, and by the type of pollutant. The main types of pollution include:

• Air pollution: The presence of pollutants in the atmosphere, such as solid particles (PM), ozone (O3), sulfur dioxide (SO2), nitrogen oxides (NOX), carbon monoxide (CO) and volatile organic compounds (VOC). These substances can come from industrial processes, the burning of fossil fuel, agriculture and natural sources, such as volcanic eruptions and forest fires.
• Water pollution: Pollution of water bodies, such as rivers, lakes, oceans and groundwater, pollutants. These pollutants may include industrial waste, wastewater, agricultural drains, oil spills and plastic. Water pollution can harm water life, make water unsuitable for drinking and lead to the spread of diseases.
• Soil pollution: The accumulation of pollutants in the soil, such as heavy metals, pesticides, herbicides, industrial chemicals and radioactive materials. Soil pollution can harm plants, animals and microorganisms, and can also pollute groundwater.
• Noise pollution: Excessive or unpleasant noise that can come from transport, industry, construction and other sources. Noise pollution can cause stress, hearing loss and other health problems.
• Light pollution: Excessive or improper use of artificial light, which can violate natural cycles, influence the wild and make it difficult to observe the stars.
• Radioactive pollution: The presence of radioactive materials in the environment, which can occur as a result of nuclear tests, accidents at nuclear power plants and radioactive waste burials. Radioactive pollution can harm human health and the environment.
• Thermal pollution: The release of heat into the environment, which can occur as a result of industrial processes and operation of power plants. Thermal pollution can increase the temperature of water and air, which can harm the water life and change the climate.
• Plastic pollution: The accumulation of plastic waste in the environment, especially in the oceans. Plastic pollution can harm the marine life, pollute the food chain and decompose into microplastics, which can fall into drinking water and food.

1.2. Sources of pollution

Pollution can be caused by many sources that can be divided into two main categories: point and scattered sources.

• Point sources: These are identified and localized sources of pollution, such as industrial enterprises, wastewater treatment plants and landfills. They are easier to control, since the source of pollution is known and can be regulated and controlled.
• Scattered sources: These are inaccurate sources of pollution, which are more difficult to identify and control, since they come from a wide range of activities such as agriculture, urban drains and transport. The regulation of multiple sources of pollution requires an integrated approach, including the use of advanced management methods, the formation and stimulation of changes in behavior.

1.3. Pollutants: classification and characteristics

Pollutants are classified according to various criteria, including their physical condition (solid, liquid, gaseous), the chemical composition (organic, inorganic) and the effect on human health and the environment. Some of the most common pollutants include:

• Solid particles (PM): Microscopic particles balanced in the air, which can be formed as a result of the burning of fossil fuel, industrial processes and construction work. The size of the particles is important because smaller particles (PM2.5) can penetrate deep into the light and serious health problems.
• Ozon (O3): The gas that is formed in the atmosphere as a result of chemical reactions between nitrogen oxides (NOX) and volatile organic compounds (VOC) in the presence of sunlight. Ozone is the main component of Smog and can cause breathing problems, especially in children and people with asthma.
• Sulfur dioxide (SO2): Gas, which is formed as a result of the burning of fossil fuel containing sulfur and industrial processes. Sulfur dioxide can cause breathing problems, and can also contribute to the formation of acid rains.
• Nitrogen oxides (Nox): A group of gases that are formed as a result of the burning of fossil fuel and industrial processes. Nitrogen oxides can cause breathing problems, and can also contribute to the formation of smog and acid rains.
• Ugric gas (CO): Colorless and not smell of gas, which is formed as a result of incomplete combustion of fossil fuel. Curular gas can reduce the ability of blood to tolerate oxygen, which can lead to dizziness, headaches and even death.
• Flying organic compounds (VOC): Organic chemicals that easily evaporate into the air. They are released from various sources, such as paints, solvents, gasoline and industrial processes. VOC can contribute to the formation of a smog and can cause various health problems.
• Heavy metals: Metals, such as lead, mercury, cadmium and arsenic, which can be toxic even in small quantities. They can fall into the environment from industrial processes, mining industry and waste burial. Heavy metals can accumulate in organisms and cause serious health problems.
• Pesticides: Chemicals used to destroy pests in agriculture and other areas. Pesticides can pollute water, soil and air, and can also harm useful insects and other animals.
• Herbicides: Chemicals used to destroy weeds. Herbicides can pollute water, soil and air, and can also harm other plants.
• Radioactive materials: Materials that radiate ionizing radiation. They can fall into the environment as a result of nuclear tests, accidents at nuclear power plants and the burial of radioactive waste. Radioactive materials can cause cancer and other health problems.
• Plastic: Synthetic materials that do not decompose easily in the environment. Plastic waste can accumulate in the oceans and on land, harming the marine life and polluting the food chain.

2. Pollution level indicators

To assess the level of pollution, various indicators are used, which allow us to quantify the concentration of pollutants and their potential impact on human health and the environment. These indicators are used to monitor the quality of air, water and soil, as well as to evaluate the effectiveness of measures to combat pollution.

2.1. Air quality index (AQI)

The air quality index (AQI) is the number used by state institutions to inform the population about the current and predicted level of air pollution. AQI is based on the concentrations of the main pollutants in the air, such as solid particles (PM2.5 and PM10), ozone (O3), sulfur dioxide (SO2), nitrogen oxides and carbon monoxide (CO).

AQi usually varies from 0 to 500, where higher values indicate a higher level of air pollution and a greater health risk. AQI is usually divided into categories, each of which is associated with a certain level of risk:

• 0-50 (good): The quality of the air is considered satisfactory, and air pollution is almost no risk to health.
• 51-100 (moderately): The quality of the air is acceptable; However, some pollutants may pose a moderate health danger to a very small number of people who are unusually sensitive to air pollution.
• 101-150 (unfavorable for sensitive groups): People with lung diseases, such as asthma, children and elderly people, are at greater risk from the effects of air pollution.
• 151-200 (adverse): Each can have some adverse effect, members of sensitive groups may experience more serious effects.
• 201-300 (very unfavorable): Everyone can experience more serious health consequences.
• 301-500 (dangerous): There is a risk of serious health consequences for the entire population.

2.2. Water quality index (wqi)

The water quality index (WQI) is the number used to assess the general quality of water based on various physical, chemical and biological parameters. WQI takes into account parameters such as dissolved oxygen (DO), biological need for oxygen (BOD), chemical need for oxygen (COD), fecal column bacteria, pH, turbidity, general dissolved solids (TDS) and concentrations of certain pollutants.

WQi usually varies from 0 to 100, where higher values indicate higher water quality. WQi is usually divided into categories, each of which is associated with a certain level of water suitability for various purposes:

• 90-100 (excellent): Water is very good quality and is suitable for drinking, bathing and supporting water lives.
• 70-89 (good): Water of good quality and suitable for most goals, but can require some processing before drinking.
• 50-69 (moderately): Water of moderate quality and can be suitable for certain purposes, such as irrigation, but not suitable for drinking or bathing.
• 25-49 (bad): Water is of poor quality and is not suitable for most goals.
• 0-24 (very bad): The water is very poor and strongly contaminated.

2.3. Soil pollution indicators

To assess the level of soil pollution, various indicators are used, which allow you to evaluate the concentration of pollutants and their effect on soil health and ecosystems. Some of the most common soil pollution indicators include:
