What is the primary function of environmental engineering?

• To design new technologies for space exploration.

• To combine natural sciences with engineering principles to solve environmental problems.

• To develop advanced weaponry for national defense.

• To create artificial intelligence for industrial automation.

What were some of the health consequences of lead contamination in Flint, Michigan's drinking water?

• Improved cognitive function and increased energy levels.

• Cardiovascular problems, neurological issues, and increased rates of Legionnaires' disease.

• Enhanced bone density and stronger immune systems.

• Increased fertility rates and decreased fetal death rates.

What pH range generally supports aquatic life in water?

• Below 3

• Above 9

• Between 6 and 8

• Exactly 7

What is the process called when chemicals are added to water to make small particles stick together, forming larger clumps that are easier to remove?

• Distillation

• Filtration

• Coagulation

• Sedimentation

What are common symptoms of carbon monoxide poisoning?

• Rash, fever, muscle aches

• Dizziness, weakness, vomiting

Why are viruses generally harder to filter out of the air than bacteria?

• Viruses are more resistant to chemical treatments.

• Viruses are typically smaller than bacteria.

• Viruses have a stronger electrical charge.

• Viruses can multiply rapidly in filters.

How do electrostatic air filters primarily remove pollutants from the air?

• By using a chemical reaction to neutralize pollutants.

• By physically trapping particles in a dense mesh.

• By positively charging air molecules and attracting them to charged plates.

• By cooling the air to condense pollutants into liquid form.

Which of the following is NOT typically addressed by environmental engineering?

• Noise pollution from highways.

• Waste management and recycling.

• Water quality and dissolved oxygen levels.

• Designing new types of vehicles for space exploration.
