2. What are the main causes for the air pollution? Factories Automobiles Energy sources Wild fires Volcano tornadoes

3. S mo g Acid rains Greenhouse effect Hole in the ozone layer

4. It’s 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.

5. Global warming Respiratory disease Plants die

6. - 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.

7. -Air pollution prevention efforts of companies have generally f o cused on w a s te reduction, reuse and recycling. -So to solve these problems and to get over them we can change our lifestyles.

8. Use of solar energy Use safe cars Plant more trees

9. WHAT IS NOISE POLLUTION? Sound that is unwanted or disrupts one’s 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 can’t see, smell, or taste it. World Health Organization stated that “Noise must be recognized as a major threat to human well-being”

10. Sources of Noise Pollution Industrial Loudspeaker Construction work Road Traffic Trains Aircrafts Radios and Microphones Agricultural Machines Defence Equipment

11. 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.

12. 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. Physical effects from noise include: vib r a t ion to buildings, damage to glass windows, plaster cracking, damage to building foundations. Jet a i rc r aft ha v e damaged roads and buildings. Environmental Effect

13. Health Effects 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 .

14. Solutions for Noise Pollution Planting 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.
