Causes of environmental pollution there are many Types of pollution and its roots There are many types of infection, such as air pollution, water pollution, soil pollution, noise pollution, thermal pollution, light pollution, the following are some types of corruption and the most important causes:
Environmental Pollution refers to the concept of environmental pollution of the introduction of substances harmful to the physical and biological components of the natural environment,
and adversely affect human organisms, and these materials are hazardous or natural materials, but they are considered contaminated when they exceed acceptable levels, can occur pollution on land, or sea or water Pollutants can be substantial, liquid or gaseous substances.
Causes of environmental pollution Air pollution
It means air pollution enter harmful substances that make the air is clean; which affects the lives of human beings, animals, plants, and examples of materials that pollute the atmosphere:
- carbon monoxide, sulfur oxides, nitrogen oxides, hydrocarbons, organic compounds, dust particles, The causes of air pollution include Oxides from burning fossil fuels, such as sulfur dioxide.
- The exhaust of vehicles, including trucks, cars, trains, and aircraft.
- Gases from pesticides, pesticides and fertilisers used in agricultural activities.
- Factory smoke that releases a large amount of carbon monoxide, hydrocarbons, chemicals, and organic compounds into the air.
- Dust and chemicals from mining operations. Chemicals from household cleaning products and paints.
Causes of environmental pollution Water pollution
Water pollution means the introduction of harmful substances directly or indirectly into rivers, seas, oceans, lakes, streams, and aquifers such as wells or aquifers, altering their chemical, biological or physical properties.
- Water pollution results from Dumping of factory wastes containing pollutants such as sulfur, asbestos, nitrates, lead, mercury and other harmful chemicals in water bodies.
- Access to wastewater carrying harmful bacteria and chemicals to water bodies.
- Mixing of chemicals from mining operations with water.
- Dumping of waste, such as paper, aluminium, rubber, glass, plastic, or food in water bodies. Oil spill from sea tankers.
- Acid rain from the burning of fossil fuels reaches water bodies.
- Chemicals that emit fertilisers and pesticides mix with rainwater and flow to water bodies. Sewage leaks from the pipes and mixes with groundwater.
- Accumulation of marine organisms dying from global warming and warming, which pollutes water bodies.
- Mixing of rainwater or groundwater with materials from landfills.
Soil pollution refers to the mixing of soil with chemicals that are not original components, but man-made, which affects the growth of plants that are the main source of human food, and the causes of soil pollution include Solid industrial wastes that accumulate on the soil surface and render them unusable.
- Soil absorption of chemicals in fertilisers and pesticides.
- Biological wastes such as urine and faeces are seeped into the soil through a sewage system, or through used diapers thrown into landfills.
- Oil seeps into the soil during transport or storage.
- Acid rain mixing with soil.
Noise pollution is caused by unwanted sounds, which can cause discomfort and discomfort in organisms in general, and for humans in particular.
Noise pollution is measured in decibel units. An industrial sound allowable limit according to the World Health Organization (75) dB, and the intensity of the noise that reaches 90 decibels, causing hearing impairment, and when it reaches the noise intensity of more than 100 dB can cause complete loss of hearing and Causes of noise pollution:
- Factory machinery, such as mills, generators, compressors, etc.
- Social events include music and dance. Transportation, such as trains, planes, and cars.
- Various construction activities such as bridges and dams, buildings, and roads. Household activities that
- produce noisy sounds such as television, pressure cookers, vacuum cleaners, washing machines, dryers, air conditioners, etc.
- Some may think that noise pollution is one of the least dangerous types of pollution, and in fact, noise pollution causes many harmful effects, including It, affects the mental health
- of human beings and causes aggression, stress and fatigue.
- It causes sleep disturbances, obstructs sleep pattern, causing constant fatigue and decreases efficiency in various daily activities.
- It causes cardiovascular disease caused by stress, and noise causes high blood pressure and increased heart rate because it naturally obstructs blood flow.
- It reduces the human ability to communicate properly, causes headaches, and disturbs the emotional balance.
- Affects hearing-dependent animals to survive, reduces hunting or escaping enemies, disrupting the environmental balance, and noise can cause noise-disturbing animals that migrate, mating, disturb pets and increase Of their aggression.
Causes of environmental pollution Thermal pollution
It means the thermal pollution change the degree of bodies of water temperature either rise or fall as a result of human activities, and the result of thermal pollution to change
the level of oxygen in the water; which negatively affects the organisms that live in the water, and plants that live near bodies of water, occurs thermal pollution for several
reasons Of which: Use water to cool power plants and machinery in factories and bring them back to the source after the temperature rises. Soil erosion causes water bodies to
rise, making them more susceptible to sunlight. Deforestation and logging, water bodies become more exposed to direct sunlight, increasing their absorption of heat, and logging
increases the concentration of greenhouse gases that cause greenhouse gases. Warming of water during a runoff on paved surfaces that are overheated, such as roads and car
parks before reaching water bodies. Natural causes increase the temperature of water bodies such as volcanoes, and other activities that produce geothermal heat, in addition to lightning.
Causes of environmental pollution Light pollution
Light pollution refers to the excessive use of industrial lights that alter the natural lighting of the environment, which affects the health and safety of humans and wildlife, the
growth of plants, leads to an increase in energy consumption, interferes with astronomical research, causes disturbance of ecosystems, and causes of light pollution
include: Excessive use of incandescent signs, decorative lights, and illumination of strong, unstudied streets. Leave unused rooms lit. Overpopulation that causes many light sources in a limited area.
