Modern cities often have high levels of pollution due to high emissions within them and poor ventilation due to building concentration.
Areas of very high pollution, “hotspots”, can occur across the city and pose increased risk to the health of its residents and workers.
What is a Pollution Hotspot?
high volume of people
high emission of pollution
= pollution hotspot
In cities, the pollution we breathe comes from many sources including transport, industry and building emissions.
Harmful Urban Pollutants
Gas phase pollutant
Solid or liquid state pollutant
Who is Most Affected by Air Pollution
Public Transportation Users
Residents and Employees on Busy Roads
Health Effects of Air Pollution
Stunts brain growth in fetuses, brain development in young children and cognition abilities in adults
Leads to cardiovasuclar diseases such as stroke and heart disease. Also can intensify existing conditions
Stunts growth in children, reduces functioning capacity in adults, causes lung cancer and asthma
