​

Of the world’s population lives

in places where air quality

levels exceed World Health Organization limits.

We all breath dangerous pollutants

every time we are in traffic and

our exposure greatly increases

when on highly congested roadways.

​

Roadways are a line source of pollution

What are we breathing?

Emissions

​

• Emissions are a mix of particulate and gaseous pollutants

​

• Fine particulate matter PM2.5 is a mix of carbon emissions, brake, tire and road dust, nitrogen oxides, sulfur dioxide and volatile organic compounds

​

• Mortality estimates related to PM2.5 more than 9million worldwide each year

  • That is more deaths per year than AIDs, tuberculosis and malaria combined

  • The deadliest pollutants are microscopic, invisible –what you can’t see can kill

​

​​

Microplastic pollution

​

• Recent sample: 7 trillion pieces of microplastics (5mm or less), most of it tire

  particles, are washed into San Francisco Bay each year (SFEI 2019) 

​

• Humans ingest each week the amount of plastic in a credit card

​

• Toxic chemicals contained in plastic cause neurological problems, cancer, birth defects, cardiovascular disease, and diabetes

Fine particulate matter PM2.5 air pollution is a major concern for human health. Due to their very small size, PM2.5 particles can penetrate deep into the human respiratory tract, into the bloodstream, and be transported to all critical organs such as the heart and brain, wreaking absolute havoc on human health
