smog. its effects, causes and control measures

2.  Type of air pollution
 Refer to smoky fog
COMPOSITION:
 NOx & SOx
 Ozone
 Smoke
Also derived from combustion and various emissions.
Types of smog:
 Sulfurous smog
- burning sulphur bearing fossil fuel.
 Photochemical smog
- NOx
- Hydrogen vapors & Sunlight
Cause eye irritation & respiratory distress

3. EFFECTS ON HUMAN HEALTH:
- Coughing & irritation
- Aggravation of asthma
- Breathing difficulty & lung damage
- Premature death(respiratory & cancer diseases)
- Birth defects & low birth weight
- Risk of developing rickets
- Can cause plane crash
EFFECTS ON PLANTS & ANIMALS :
- Damage to crops
- Interferes with infections fighting ability
- Difficult for animal species to survive
- Make susceptible to illness

4.  who engages in strenuous outdoor activity
- breathe faster & more deeply, exposing their lungs to
more ozone and other pollutants
 CHILDREN _prone to asthma & other respiratory
disorders
 ADULTS WHO ARE ACTIVE OUTDOORS
 PEOPLE WITH RESPIRATORY DISEASES _more
sensitive even at lower level
 PEOPLE WITH UNUSUAL SUSCEPTIBILTY TO
OZONE _allergic to smog pollutants

5.  Awareness campaigns
 Changing car habits
- Drive less
- Maintain car
- Fuel up in cooler temp.
- purchase a hybrid or electric vehicle
 Avoid high VOC products
 Energy efficient in your homes.
 Don’t promote organizations having poor
environmental practices.

airports
Control measures
- Sahara Forest Project
- Generate humid climate

11.  Anthropogenic greenhouse gas emission
 Man derived emissions
 Necessary to curb emissions
 The International Energy Agency’s
assessment
