Water Pollution

100

What primary treatment in a sewage plant is designed to remove

Solids

200

This is what makes mercury especially dangerous to the general public 

Its accumulation as it moves up the aquatic food chain (Small fish --> Bigger fish --> Humans) 

300

Presence of fecal coliform bacteria in a lake indicates this

That a more harmful microorganism is in the water

400

Negatives of sediment pollution include these 3 things

Increase in turbidity (cloudiness) of the water

Reduction of sunlight

Clogging of fish gills

500

These are all methods of cleaning oil spills

Bacteria that can consume oil

Chemicals that break up and disperse oil

Plastic barriers 

Vacuums 

Air Pollution

100

This type of ozone is beneficial, while this type is dangerous

Stratospheric is beneficial

Tropospheric is dangerous

200

This is one of the biggest reasons why carbon monoxide is dangerous to our health

CO bonds with hemoglobin in blood and interferes with oxygen transfer (This is why CO poisoning often kills people by putting them to sleep...Their brain is not getting enough oxygen)

300

These are the two main HUMAN sources of carbon dioxide

Deforestation

Combustion due to fossil fuels

400

These are several methods used to reduce particulate matter emissions

Smokestacks

Filters

Electrostatic precipitators

Scrubbers

500

This can cause the breakdown of stratospheric ozone

Emission of CFC's

Free chlorine atoms in atmosphere

Waste

100

This is the largest component of MSM in the U.S.

Paper

200

This is the primary method of waste disposal in the U.S.

Sanitary landfill

300

These are several problems associated with disposal of waste in open dumps

Attraction of pests

Physical hazards

Water pollution

Chemical hazards

400

This act protects human health and the environment by reducing source hazardous waste

Resource Conservation and Recovery Act (RCRA)

500

These are several reasons why recycling aluminum is beneficial

Reduces effects on land from mining

Reduces effects of leaching

Reduces energy required to transport mind ore

Health and Risk

100

This historical disease is caused by bacteria carried by rodents

Plague

200

ED50 can be described as this

Effective dose that causes 50% of the individuals to display harmful, but not lethal, effects

300

The Innocent-Until-Proven-Guilty priniciple states this

Chemicals can enter the marketplace until scientific data definitively demonstrates harm 

400

The following shows how a chemical can travel through a food chain by this process

Phytoplankton --> Zooplankton --> Small fish --> Large fish 

Biomagnification 

500

HIV and AIDS cannot be spread by this method

Airborne pathogen

Misc.

100

Eutrophic areas are typically created because of this 

Increase concentration of nitrates and phosphates (fertilizer)

200

Human wastewater deposition into bodies of water can cause this

Cultural eutrophication

Pathogen increase in water supply

300

The Clean Water Acts DOES NOT protect this 

Groundwater

400

These are several problems associated with acid deposition

Affected aquatic systems

Lower pH of lakes

Erosion of marble monuments

Erosion of paint

500

SO₂ can come from what sources

Human activities like combustion of fuels

Volcanic eruptions- large quantities

Forest fires-smaller quantities
