Air Pollution and Health Problems

Air pollution cause serious health problems especially for people who are: • • • very young very old who have heart or lung problem

Air pollution adds to the effects of existing diseases • emphysema • heart disease • lung cancer

Air Pollution: Health Problems Short-Term Effects: • Don’t last long • Are reversible if exposure to the air pollutant decreases • Include: § § § § headache nausea irritation to eyes, nose, throat tightness in chest coughing bronchitis pneumonia

Asbestos

Asbestos: a silicate mineral

Asbestos • Used in some types of insulation and as a fire retardant • Inhaled asbestos fiber can cut and scar the lungs disease asbestosis

Asbestos Exposure Regions

Noise Pollution

Noise Pollution • Affects human health and quality of life § Loss of hearing, sleep § High blood pressure § Stress

The intensity of sound is measured by decibels (d. B)

Light Pollution

Light Pollution • Not a health hazard • Can negatively affect the environment § Ex. : Wasted energy if used improperly
