What is the Air Pollution? Toxic or radioactive gases that introduced into the atmosphere as a result of human activity.

Dirty air that could injure human health or property, or animal life, and/or prevent normal plant use and enjoyment of property.

What are the main causes for the air pollution? Factories


Energy sources

Wild fires



Outdoor Air PollutionSmog

Acid rains

Greenhouse effect

Hole in the ozone layer

Indoor air pollutionIts more dangerous than the outdoor pollution, because we do everything in enclosed environments where air circulation may be restricted. There are many sources of indoor air pollution: tabacco smoke, cooking and heating appliances, and vapors from building materials.

How does the air pollution effect our planet?Global warming Respiratory diseasePlants die

Health effects-Some individuals are much more sensitive to pollutants than are others. -Air pollution can affect our health in many ways with both short-term and long-term effects.


-Air pollution prevention efforts of companies have generally focused on waste reduction, reuse and recycling. -So to solve these problems and to get over them we can change our lifestyles.

How can we help to not cause more air pollution?Use of solar energy

Use safe cars

Plant more trees

What is Noise Pollution?11WHAT IS NOISE POLLUTION?Sound that is unwanted or disrupts ones quality of life is called as noise. When there is lot of noise in the environment, it is termed as noise pollution.

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

It is an underrated environmental problem because of the fact that we cant see, smell, or taste it.

World Health Organization stated that Noise must be recognized as a major threat to human well-being

Sources of Noise PollutionIndustrial


Construction work

Road Traffic



Radios and Microphones

Agricultural Machines

Defence Equipment


Effect on human health..

Auditory effects interfering with hearing; auditory fatigue and deafness.

Physiological effects affecting biological functions; anxiety, neurosis, insomnia, dizziness, nausea, fatigue, visual symptoms, hypertension, cardiovascular symptoms, liver changes, nervous symptoms, changes in skin, fast irregular heart beats (tachycardia).

Endocrine and hormonal changes relating to stress and noise levels. i.e. raised adrenaline and cholesterol. Noise causes blood vessels to close cutting down blood supply to the fingers and toes. Respiratory changes occur due to noise. Psychological effects; physical and mental fatigue, loss of concentration, lower efficiency, reduced output, absenteeism, higher rates of accidents, behavioural changes, errors at work, loss of sleep, psychosomatic disorders, diseases related to stress, mental illness, aggravation of existing stress problems and mental illness, neurotic effects, rage anger, crime.

Non-auditory effects interfering with social behaviour; problems with communications, sleep, recreation, mental equilibrium (peace), and the ability to concentrate at work.

Noise can have a negative effect on humans, domestic and wild animals, ecological systems, buildings and other structures. Effects of noise on wildlife Reduced migration of birds and other animals.Loss of food habitats if animals are driven away.Animals in city zoos tend to become lethargic and their health deteriorates. Animals tend not to reproduce, which threatens their survival.Other effects include duodenal ulcers, atrophy of the thymus gland, and changes to adrenal glands. Effects of noise on structures Physical effects from noise include: vibration to buildings, damage to glass windows, plaster cracking, damage to building foundations. Jet aircraft have damaged roads and buildings. Environmental EffectHealth EffectsThere 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.Solutions for Noise PollutionPlanting bushes and trees in and around sound generating sources is an effective solution for noise pollution.

Regular servicing and tuning of automobiles can effectively reduce the noise pollution.

Buildings can be designed with suitable noise absorbing material for the walls, windows, and ceilings.

Workers should be provided with equipments such as ear plugs and earmuffs for hearing protection.

Solutions for Noise PollutionSimilar to automobiles, lubrication of the machinery and servicing should be done to minimize noise generation.

Soundproof doors and windows can be installed to block unwanted noise from outside.

Regulations should be imposed to restrict the usage of play loudspeakers in crowded areas and public places.

Factories and industries should be located far from the residential areas.

Community development or urban management should be done with long-term planning, along with an aim to reduce noise pollution.

Social awareness programs should be taken up to educate the public about the causes and effects of noise pollution.

Noise pollution often persists because only five to ten percent of people affected by noise will lodge a formal complaint.

Many people are not aware of their legal right to quiet and do not know how to register a complaint.

conclusionIf everyone would help to save the earth we would live in a safe environment!
