Vicki begins by asking the question, “what do you think is in the air that we breathe?” Aerosols are rarely talked about, yet they are having a significant effect on the quality of the air we breathe.
These particles are typically a thousand times smaller than the width of a hair, and they come from a variety of sources, such as car exhaust and factories, as well as volcanoes and wildfires. The ocean also contributes to the story, with viruses, bacteria, phytoplankton and enzymes present in sea air.
In addition, dust particles from Asia find their way to the shores of the United States. Airborne particles such as these can negatively affect the upper respiratory tract, and recent research indicates that they can affect our brain.
