ENVIRONMENTAL POLLUTION

*Environmental Pollution can be defined as any undesirable change in physical, chemical, or biological characteristics of any component of the environment i.e. air, water, soil which can cause harmful effects on various forms of life or property.

*Pollution: The term pollution can be defined as influence of any substance causing nuisance, harmful effects, and uneasiness to the organisms.

*Pollutant:- Any substance causing Nuisance or harmful effects or uneasiness to the organisms, then that particular substance may be called as the pollutant.

TYPES OF POLLUTION

*WATER POLLUTION

*AIR POLLUTION

*LAND POLLUTION

*NOISE POLLUTION

WATER POLLUTION

*Water Pollution can be defined as alteration in physical, chemical, or biological characteristics of water through natural or human activities and making it unsuitable for its designated use. Fresh Water present on the earth surface is put to many uses. It is used for drinking, domestic and municipal uses, agricultural, irrigation, industries, navigatio n, recreation. The used water becomes contaminated and is called waste water.

SOURCES OF WATER POLLUTION

*Most of Water Pollution is man made It may also occur naturally by addition of soil particles through erosion animal wastes and leaching of minerals from rocks.

*The sources of water pollution can be classified as;

*Municipal Waste Water

*Industrial Waste

*Inorganic Pollutants

*Organic Pollutants

*Agricultural Wastes

*Marine Pollution

*Thermal pollution

AIR POLLUTION

*Air pollution is the introduction of chemicals, particulate matter, or biological materials that cause harm or discomfort to humans or other living organisms, or cause damage to the natural environment or built environment, into the atmosphere.

*A substance in the air that can cause harm to humans and the environment is known as an air pollutant.

CAUSES OF AIR POLLUTION

*Carbon dioxide-this happens because of Deforestation and fossil fuel burning.

*Sulfur dioxide –Due to the burning of sulfur containing compounds of fossil fuels.

*Sulfur oxides- very dangerous to humans at a high concentration. Sulfur in the atmosphere is responsible for acid rain.

CONSEQUENCES OF AIR POLLUTION

*CO2 is a good transmitter of sunlight, but it also partially restricts infrared radiation going back from the earth into space, which produces the socalled greenhouse effect that prevents a drastic cooling of the Earth during the night. CO2 in atmosphere –> GLOBAL WARMING

LAND POLLUTION

*Land pollution is the demolition of Earth’s land surfaces often caused by human activities and their misuse of land resources. It occurs when waste is not disposed properly.

*Urbanization and industrialization are major causes of land pollution.

CAUSES OF LAND POLLUTION

*Four Main causes of land pollution:

*Construction

*Agriculture

*Domestic waste

*Industrial Waste

NOISE POLLUTION

*Noise pollution is excessive, displeasing human, animal, or machine-created environmental noise that disrupts the activity or balance of human or animal life.

*Sound becomes undesirable when it disturbs the normal activities such as working, sleeping, and during conversations.

*World Health Organization stated that “Noise must be recognized as a major threat to human wellbeing”

SOURCES OF NOISE POLLUTION

*Transportation systems are the main source of noise pollution in urban areas.

*Construction of buildings, highways, and streets cause a lot of noise, due to the usage of air compressors, bulldozers, loaders, dump trucks, and pavement breakers.

*Industrial noise also adds to the already unfavorable state of noise pollution.

*Loud speakers, plumbing, boilers, generators, air conditioners, fans, and vacuum cleaners add to the existing noise pollution.

EFFECTS OF NOISE POLLUTION

*According to the USEPA, there are direct links between noise and health. Also, noise pollution adversely affects the lives of millions of people.

*Noise pollution can damage physiological and psychological health.

*High blood pressure, stress related illness, sleep disruption, hearing loss, and productivity loss are the problems related to noise pollution.

*It can also cause memory loss, severe depression, and panic attacks.
