Basics
What does TRWP stand for?
Tire (and) Road Wear Particles
True or false: 6PPD is in all tires.
True
True or false: Loads of research has been done on the effects of TRWPs on human health, so we know what the exact long-term effects are.
False
True or false: Driving with under-inflated tires releases less TRWPs because there is less abrasion.
False
How many hours minimum do you need to let your Coordinator know of an absence, tardy, or scheduling conflict?
12 hours
What are TRWPs a mixture of?
Road surface material and tire tread fragments
What does 6PPD react with in the atmosphere?
ozone (O3)
People living near _____ are exposed to higher levels of TRWPs.
busy roads
In what state was 6PPD made a “Priority Chemical”?
California
Within how many hours are you expected to respond to all internship communications?
24 hours (at least give my messages a reaction!!)
TRWPs are formed from the combination of ____ and ____ when driving.
heat and friction
What is the purpose of having 6PPD as a chemical additive in tires?
to prevent tires from cracking
What are two potential ways that TRWPs can enter the bloodstream?
- inhalation
- ingestion
- dermal contact
In what region of the world do some countries collect and treat rain water for microplastics?
Europe
How many excused absences (that you do not made up by the end of the semester) will count as one unexcused absence?
three
What word describes TRWPs that are airborne and can be inhaled?
ultrafine
What by-product is produced when 6PPD reacts with the atmosphere?
6PPD-quinone (6PPD-q)
What are two examples of health issues that TRWPs can contribute to?
- respiratory disease (ie. asthma)
- cardiovascular disease
- neurological / developmental issues
- cancers
How can we design tires to be more sustainable?
Make them longer lasting or find alternatives to harmful materials
How can you make up missed internship hours?
You can make up hours for missed meetings/events by attending extra events with other Earth Teams or on Zoom
About how many TRWPs per kilometer can a single car emit?
1 trillion
6PPD-q is toxic to which fish species?
Coho salmon
What are two examples of harmful components in TRWPs?
- microplastics
- heavy metals
- chemicals (ie. 6PPD or 6PPD-q)
- carcinogenic organic compounds
What type of green infrastructure could help trap TRWPs before they enter watersheds?
Bioswales = open channels with natural plants designed to manage stormwater runoff by slowing it down and filtering out pollutants
How many unexcused absences can you accumulate per semester before being dismissed from the internship?
Two (will require you to schedule a 1-on-1 meeting with me)
