Health Effects of Outdoor Air Pollution
The effects depend on the dose or concentration
Primary effects:
Toxic poisoning
Cancer
Birth defects
Eye irritation
Irritation of the respiratory system
Increased susceptibility to heart disease
Aggravation of chronic diseases such as asthma and emphysema
Seven Common Outdoor Air Pollutants
Primary air pollutants
Particulate matter
Carbon monoxide
Nitrogen oxides
Sulphur oxides
VOC
(Volatile Organic Compounds)
Lead
Secondary air pollutant
Ground level Ozone
Particulate matter (PM 10and PM 2.5)
Particles found in the air (dust, soot, smoke, and liquid droplets)
Big and small
Vehicles, factories, construction sites, tilled fields, stone crashing, burning
Some formed in the air
Serious health effects
Carbon Monoxide
Odourless, colourless gas
- Incomplete burning of carbon containing fuels
Heaters, woodstoves, gas stoves, fireplaces, water heaters, automobile exhaust, tobacco
smoke
Health effects of Carbon monoxide
Interferes with the delivery of oxygen in the blood to the rest of the body
Worsen cardiovascular conditions
Fatigue
Headache
Weakness
Confusion
Disorientation, loss of coordination
Nausea, Dizziness, Death
Prevention
Never leave a car engine running in a shed or garage or in any enclosed space
