Understanding PCBs and Bioremediation Efforts

What are PCBs and why are they still a concern despite being banned?

• They are a type of bacteria used in bioremediation.

• They are a harmless byproduct of industrial processes.

• They are a type of paint used on roads.

• They are chemicals that persist in the environment and can cause harm.

How do PCBs primarily enter the Spokane River?

• Through direct industrial discharge.

• Via stormwater runoff.

• Through natural soil erosion.

• By being dumped illegally.

What is the main goal of the research conducted by students at North Central High School?

• To develop new types of road paint.

• To find effective bacteria for PCB bioremediation.

• To create a new chemical process for PCB production.

• To study the effects of PCBs on human health.

What unique advantage does North Central High School have for conducting PCB research?

• It has a partnership with local industries.

• It has the largest student body in Washington State.

• It is located near the Spokane River.

• It has a premier science lab with advanced equipment.

What is the next step for the students' research on PCBs?

• To conduct larger scale and outdoor experiments.

• To focus on developing new PCB compounds.

• To publish their findings in a scientific journal.

• To stop the research due to lack of funding.
