This disease has symptoms of mild fever, rash, conjunctivitis, and joint or muscle pain. It is transmitted though mosquitoes and can cause potential defect to a baby if you are pregnant when contracting this disease.

What is Zika Virus?

100

This type of sewage treatment physically removes solids and larger debris from wastewater 

What is Primary Treatment?

100

This type of pollution is typically released from nuclear power plants.

What is Thermal pollution?

Describe the difference between bioaccumulation and biomagnification.

Bioaccumulation is the buildup of toxins in an individual organism over time, while biomagnification is the increase in toxin concentration as it moves up through the food chain.

100

This term is used for how much a chemical will kill half a population.

What is LD50?

200

This disease caused a global pandemic back in 2020.

What is SARS?

200

This sewage treatment is not always used and expensive. It uses a combination of chemical and ecological processes to remove remaining pollutant within the sewage.

What is tertiary treatment? 

200

As BOD increases what happens to oxygen levels?

What is decrease?

200

This persistent pollutant was used in coolants and lubricants, but is now banned due to it's ability to bioaccumulate in organisms and it's extreme toxicity.

What are PCBs?

200

NOEL stands for.

WHat is no observed effect level.

300

This disease is typically spread through contact with contaminated food or water, and can cause stomach pain and diarrhea.

What is dysentery?

300

This sewage treatment level involves the use of a grit chamber.

What is Primary Treatment?

300

Agricultural runoff can cause waterways to become...

What is Oligotrophic?

300

Because of biomagnification, which trophic levels is most effects by POPs?

WHat is the tertiary consumer?

300

This effect is when a harmful impact of a toxin or stressor does not cause immediate death but impairs an organism’s behavior, reproduction, growth, or physiology.

What is a sublethal effect.

400

This disease is spread through the air, and is caused by bacterium. This disease primarily effects the lungs and can cause coughing and sneezing.

What is tuberculosis?

400

This type of sewage treatment uses bacteria and biological processes to break down organic matter.

What is Secondary Treatment?

400

What happens to bacteria levels during eutrophication?

What is they decrease then increase?

400

This synthetic pesticide was once used in fertilizers but was banned due to its harmful effects on ecosystems when is bioaccumulation amongst organisms.

What is DDT?

400

This study investigates the effects of long-term, repeated exposure to lower concentrations, revealing impacts that develop over time such as reproductive failure or cancer.

What is a chronic study?

500

This disease causes fever, headache, and body aches, and is transmitted via misquitos.

What is the West Nile Virus?

500

This level of sewage treatment typically happens in aeration tanks.

What is Secondary Treatment?

500

Identify two specific water quality indicators that would provide evidence of nutrient pollution in the river system.

WHat is decreased DO, and increased nitrates.

500

This pollutant bioaccumulation in organisms, and biomagnifies across the food web. When converted by bacteria, and accumulated in fish, it can cause serious neurological and developmental risks to humans and wildlife to humans who consume these fish.

What is methylmercury?

500

This study examines the effects of a single, short-term exposure to a stressor or toxin, often at high concentrations.

What is an acute study?
