100
another word for discarded electronic devices including televisions, cell phones, and computers
e-waste
100
What does POP stand for?
persistant organic pollutant
100
a source of pollution which can be hard to identify, such as pesticide spraying or urban runoff
non-point sources of pollution
100
chemicals that can interfere with the endocrine system of animals
endocrine disruptors
100
True or false: Specific pathogens can occur in many environments regardless of the appearance of sanitary conditions
True
200
When waste is burned at high temperatures which reduces the volume of solid waste but releases air pollutants?
incineration
200
What part of the body do POPs accumulate in?
they are soluble (dissolve into) fatty tissues
200
What is an example of a point source of pollution?
smokestack (into the atmosphere), waste discharge pipe, etc
200
What is one benefit that wetlands provide for ecosystems?
water purification, flood protection, water infiltration, and habitat
200
a bacterial disease that is contracted from infected water
cholera
300
What is water that has ran through a landfill, thus a collection system is needed for it?
leachate
300
What is the difference between bioaccumulation and biomagnification?
bioaccumulation = accumulation of a chemical within an organism
biomagnification = increase of a chemical within a food chain
300
What element when entered in aquatic environments will bacteria take it and convert it into a more toxic version?
mercury; bacteria in water convert it to a highly toxic methylmercury
300
What is the relationship between water temperature and dissolved oxygen? AND what type of pollution affects this relationship?
warm water = less dissolved oxygen. cold water = more dissolved oxygen. Thermal pollution
300
a form of pneumonia which is transferred by inhaling or touching infected fluids
Severe acute respiratory syndrome. SARS
400
Name at least 3 parts of a landfill that we still need to manage/create systems for
bottom liner (plastic or clay), storm water collection system, a leachate collection system, a cap, and a methane collection system
400
In eutrophication, what is the vocab word for low DO? What is the vocab word for high DO? (May use AP textbook)
hypoxia = bodies of water low in dissolved oxygen
oligotrophic = high dissolved oxygen, less nutrients
400
What is an example of a "disinfectant" which kills bacteria in a sewage treatment system? (What kills bacteria in water?) (May use AP textbook)
chlorine, ozone, UV light, etc
400
What is composting and what are 2 negative effects of it that we discussed?
breaking down organic material to use in fertilizer; odor and rodents
400
Name the 3 diseases transmitted, mainly by mosquitoes (you may use the AP textbook)
Malaria, West Nile Virus, Zika
500
What are the two landfill mitigation strategies we discussed? (ways to reduce the negative effects of landfills)
burning waste for energy and restoring habitat on former landfills
500
What trophic level of a food chain are going to be most affected by biomagnification? Why?
highest level (secondary or tertiary consumers), concentration of a substance will increase
500
As in the oxygen sag curve, bacteria use ______ , depleting it from water. This same phenomenon is used in treating waste water in secondary treatment of sewage.
Oxygen. Bacteria break down organic matter into carbon dioxide and inorganic sludge. Aeration (use of oxygen) is necessary to increase the rate at which the bacteria break down the organic matter.
500
What is the lethal dose 50 (LD50) of the following data?
about 1 molar
500
a bacterial infection that typically attacks the lungs which is spread by breathing in the bacteria from the bodily fluids of an infected person
tuberculosis
