Hello friends, here I show you How to Make Pollution Model with Thermocol and other basic objects. Please see carefully and make it easily. It will help the students of the school/college to create their project. Thank you.
Materials Required: Thermocol, Tissue Paper, Acrylic Colors, synthetic cotton, PVC Pipe, Card Board, Black Art Paper, Artificial Plant, Toy car, White Glue, Knife, etc.
WHAT IS POLLUTION?
pollution, also called environmental pollution, the addition of any substance (solid, liquid, or gas) or any form of energy (such as heat, sound, or radioactivity) to the environment at a rate faster than it can be dispersed, diluted, decomposed, recycled, or stored in some harmless form. The major kinds of pollution, usually classified by environment, are air pollution, water pollution, and land pollution. Modern society is also concerned about specific types of pollutants, such as noise pollution, light pollution, and plastic pollution. Pollution of all kinds can have negative effects on the environment and wildlife and often impacts human health and well-being.
TYPES OF POLLUTION:
As stated before, there are different types of pollution, which are either caused by natural events (like forest fires) or by man-made activities (like cars, factories, nuclear wastes, etc.) These are further classified into the following types of pollution:
• Air Pollution
• Water Pollution
• Soil Pollution
• Noise Pollution
Besides these 4 types of pollution, other types exist such as light pollution, thermal pollution and radioactive pollution. The latter is much rarer than other types, but it is the deadliest.
AIR POLLUTION:
Air pollution refers to the release of harmful contaminants (chemicals, toxic gases, particulates, biological molecules, etc.) into the earth’s atmosphere. These contaminants are quite detrimental and in some cases, pose serious health issues. Some causes that contribute to air pollution are:
• Burning fossil fuels
• Mining operations
• Exhaust gases from industries and factories
WATER POLLUTION:
Water pollution is said to occur when toxic pollutants and particulate matter are introduced into water bodies such as lakes, rivers and seas. These contaminants are generally introduced by human activities like improper sewage treatment and oil spills. However, even natural processes such as eutrophication can cause water pollution.
Other significant causes of water pollution include:
• Dumping solid wastes in water bodies
• Disposing untreated industrial sewage into water bodies
• Human and animal wastes
• Agricultural runoff containing pesticides and fertilizers.
SOIL POLLUTION:
Soil pollution, also called soil contamination, refers to the degradation of land due to the presence of chemicals or other man-made substances in the soil. The xenobiotic substances alter the natural composition of soil and affect it negatively. These can drastically impact life directly or indirectly. For instance, any toxic chemicals present in the soil will get absorbed by the plants. Since plants are producers in an environment, it gets passed up through the food chain. Compared to the other types of pollution, the effects of soil pollution are a little more obscured, but their implications are very noticeable.
Some of the common causes of soil pollution are:
• Improper industrial waste disposal
• Oil Spills
• Acid rain which is caused by air pollution
• Mining activities
• Intensive farming and agrochemicals (like fertilizers and pesticides)
• Industrial accidents
NOISE POLLUTION:
Noise pollution refers to the excessive amount of noise in the surrounding that disrupts the natural balance. Usually, it is man-made, though certain natural calamities like volcanoes can contribute to noise pollution.
In general, any sound which is over 85 decibels is considered to be detrimental. Also, the duration an individual is exposed plays an impact on their health. For perspective, a normal conversation is around 60 decibels, and a jet taking off is around 15o decibels. Consequently, noise pollution is more obvious than the other types of pollution.
Noise pollution has several contributors, which include:
• Industry-oriented noises such as heavy machines, mills, factories, etc.
• Transportation noises from vehicles, aero planes, etc.
• Construction noises
• Noise from social events (loudspeakers, firecrackers, etc.)
• Household noises (such as mixers, TV, washing machines, etc.)
