LT 21
The amount of oxygen needed by aerobic organisms (mostly due to decomposition)
What is biological oxygen demand (BOD?)
Pollutants that are created due to chemical reactions in the Earth's atmosphere.
What are secondary pollutants?
Sanitary landfills are lined with this material to prevent leachate from entering aquifers.
This is how malaria is spread.
What are mosquito bites?
It is hard to pinpoint the source of this type of pollution?
What is nonpoint source pollution?
The increase of nutrients in a body of water
What is eutrophication?
The two primary pollutants involved in the formation of photochemical smog.
What are NOx and VOCs?
Electronic waste can leach these heavy metals.
What is mercury, lead, and cadmium?
The dosage that kills 50% of a population.
What is LD50?
This type of pollution is harmful to migratory animals and animals that communicate via echolocation.
What is noise pollution?
The biological treatment of sewage water which includes using microorganisms to decompose organic material.
What is secondary treatment?
The two main secondary pollutants that make up acid deposition.
What are sulfuric acid (H2SO4) and nitric acid (HNO3)?
This type of waste disposal can be used for cogeneration.
What is waste incineration?
What is biomagnification?
Indoor air pollution is more harmful in developing countries due to the use of this type of renewable energy.
What is biomass?
This type of pollution is often discharged from power plants and it causes a reduction of dissolve oxygen in water.
What is thermal pollution?
The chemical reaction that depletes stratospheric ozone.
This law collects monetary funds from chemical companies to clean up hazardous waste sites.
What is the Superfund Act (CERCLA)?
Infectious disease is on the rise due to these 2 reasons.
What is globalization and climate change?
This law gives the EPA power to regulate the emissions of 6 major air pollutants.
What is the Clean Air Act?
This type of decomposition is responsible for lowering dissolved oxygen levels.
What is aerobic decomposition?
The chemical reactions that form photochemical smog.
NO2 + O2 + sunlight --> NO + O3
NO + VOCs --> photochemical oxidants (PANs)
O3 + PANS --> photochemical smog
This type of decomposition is responsible for methane emissions in landfills.
What is anaerobic decomposition?
What is any of the following: DDT, pesticides, BPA, POPs, microplastics, dioxins?
True or false: Increased nutrient levels lead to a decrease in pH.
What is FALSE!
