It is estimated that initially the Deepwater Horizon oil platform accident released 53,000 barrels of oil per day. If one barrel contains 42 gallons, how many gallons per day were released?

3 million

6 million

2 million

1 million

The WHO estimates that approximately 1.1 billion people worldwide do not have access to sufficient safe-water supplies. This number represents about ____ of the world population.

1/10

3/4

1/6

2/9

Which is a heavy metal associated with burning coal?

Tetanus

Lead

Mercury

Arsenic

Which is a type of wastewater? I. Sewage water from toilets II. Water from showering and bathing III. Water from washing clothes

I & II

Only I

I, II, & III

Only III

Which pollutant is most likely to be naturally released into groundwater supplies w/out human intervention

Mercury

Tetanus

Arsenic

Lead

Put the events leading to cultural eutrophication in the correct order: 1- leaching of nutrients from fertilized agricultural lands 2- fish die-off 3- algal bloom

1, 2, 3

3, 1, 2

1, 3, 2

2, 1, 3

All of the following are diseases caused by wastewater exposure except...

Cholera

Typhoid Fever

Pneumonia

Hepatitis

Which of the following is not usually associated with eutrophication?

Algal blooms

Reduced photosynthesis in the water column

Increased heavy metal concentrations

Reduced dissolved oxygen

What is true of a lake that is experiencing eutrophication?

Decreased algae

Increased oxygen

Increased nutrients

Decreased sediments

Endocrine disruptors affect what?

Red blood cells

Carbon dioxide in blood

Hormones

Hemoglobin levels

Why are persistent organic pollutants (POPs) so harmful?

They release greenhouse gases into the atmosphere

They confuse birds during flight because of noise pollution

They are soluble in fat so they accumulate in organisms

They release radioactive materials in water

Releasing lots of sewage and organic wastes will result in

Increase in dissolved oxygen

Decrease in water temperature

Increase in biological oxygen demand

Decrease in bacteria

Which would result from destroying wetland mangroves?

Increased biodiversity

Increased levels of oxygen

Increased flooding

Decreased sediments

How does dissolved oxygen result in algae blooms?

Increased temperature increases waste from fish, which provide energy for algae

Increased temperature leads to more dissolved oxygen, which helps algae grow

Low oxygen kills fish, which decompose and produce nutrients for algae

Increased temperature and less dissolved oxygen make fish move, decreasing competition so algae can grow

What would be a possible consequence of endocrine disruptors that have runoff into a lake?

Increased food web interactions

Decreased turbidity of the water

Increase in birth defects of fish

Increased dissolved oxygen

Which is a supporting ecological service of coral reefs?

Reefs cycle nitrogen

Ecotourism brings in revenue

Home for many organisms

They are pretty for art and books

Which would cause eutrophication?

Increased recreational use of a lake

Cooler temperatures in an area

Phosphorus from runoff

Reduced dissolved oxygen

Thermal Pollution is most commonly caused by

CFCs reduce the ozone layer and allow more UVB to reach the troposphere.

Wastewater treatment centers discharging purified water

Power Plants discharging water used as a coolant

Climate change heating the entire ocean

Which of the following is not an example of ecosystem services provided by mangroves?

Fish rookery

Flood protection from hurricanes

Large quantities of harvestable timber

Water filtration

When identifying tolerable limits for toxins, scientists often use

Heirdyweinberg Equilibrium

Dose-response curves

Lethal dose curves

Population dynamic curves
