Microplastics are tiny plastic particles, typically smaller than 5 millimeters (0.2 inches) in diameter.  They result from either the breakdown of larger plastic items or intentional manufacturing for use in a variety of products. They contaminate oceans, soil, food, and air, and are associated with potential risks to wildlife and human health.  It is nearly impossible to avoid some exposure to microplastics due to their widespread presence in the environment.  They are generally not biodegradable and persist in the environment for hundreds of years.  The presence of microplastics in the environment is cause for concern.  Detection and removal of microplastics from the environment is complex and difficult.  This course addresses what is known and not known about microplastics at this point in time.

After completing the course, students will be able to describe:

  What are microplastics?

  Where do microplastics come from?

  Where are microplastics found?

  How are humans exposed to microplastics?

  What are the potential health effects of microplastics?

  What are sources of microplastics?

  How are microplastics detected in the environment?

  How are microplastics removed from drinking water?

  What regulations related to microplastics are in place?
