Toxic Things (Not My Ex)
100
This process causes buildup of persistent organic pollutants in most aquatic organisms because POPs are fat soluble; so, they reside in fat tissue and are not removed.
What is Bioaccumulation?
100
This stage of sewage treatment removes organic matter using bacteria boosted by aeration.
What is Secondary Sewage Treatment?
100
Old phones, computers, monitors, etc., are considered this type of waste that contain POPs as well as several toxic heavy metals.
What is e-Waste?
100
Elevated levels of these, normally limiting nutrients, are the cause of eutrophication.
What are Nitrogen and Phosphorus?
100
Caffeine, Nicotine, Water.
Put these in order from highest (first) to lowest (last) LD50.
What are Water, Caffeine, and Nicotine?
200
This POP was once used globally to control mosquitos and also in American farms to control insect pests.
What is Dichlorodiphenyltrichloroethane (DDT)?
200
Sewage, especially without tertiary sewage treatment, can cause this environmental problem in aquatic ecosystems?
What is Eutrophication?
200
This is one of the major alternatives to MSW and produces substantial air pollution as well as toxic waste residues.
What is Incineration?
200
The level of this gas (two words) drops during eutrophication.
What is Dissolved Oxygen?
200
The LD50 of a toxin (or disease) is defined this way.
What is the dose at which half of the test population is killed by the toxin (or disease)?
300
Many POPs are endocrine disruptors that have these two main effects.
What are Fertility Disorders and Developmental Disorders?
300
The last thing done to sewage before release involves either ultraviolet light or chemicals to do this.
What is kill pathogens?
300
These are three critical components of sanitary landfills that ensure waste pollution doesn't get into aquifers.
What are an Impermeable Liner, Leachate Collection System, and Monitoring?
Methane collection is often, but not always used (and isn't considered a necessary component).
300
Eutrophication can lead to ecosystem disruption because of toxic algae blooms and these two changes.
What are increased turbidity and decreased DO?
300
The LD50 of this toxin.
What is 10 micrograms/kg?
400
This process occurs in an aquatic ecosystem due to a combination of POPs in prey and the 10% Rule, resulting in very high levels of POPs in higher trophic levels.
What is Biomagnification?
400
These are two common waterborne diseases spread due to low water quality which can result from untreated sewage.
What are Typhoid, Cholera, Dysentery, Hepatitis A, and E. coli (choose 2)?
400
This law was enacted to regulate solid and hazardous waste.
What is the Resource Conservation and Recovery Act (RCRA)?
400
The name of this graph that describes DO levels in flowing water exposed to waste containing N and/or P.
What is the Oxygen Sag Curve?
400
Three common toxic heavy metals.
What are Arsenic, Lead, Mercury, Cadmium, and Chromium (any 3 of these 5)?
500
The "Dirty Dozen" POPs recognized by the Stockholm Convention are aldrin, chlordane, dieldrin, endrin, heptachlor, hexachlorobenzene, mirex, toxaphene, polychlorinated biphenyls (PCBs), DDT, PCDD (dioxins) and PCDF (furans). This is a more recently identified POP that is used to make anti-stick coatings as well as foams.
What are Per- and Polyfluoroalkyl substances?
500
This stage of sewage treatment removes large particles in sewage using screens and gravity sedimentation.
What is Primary Sewage Treatment?
500
This law, also known as Superfund, regulates large cases of hazardous waste and its cleanup.
What is the Comprehensive Environmental Response, Compensation, and Liability Act (CERCLA)?
500
This describes the amount of oxygen needed to support respiration of consumers and decomposers.
What is Biochemical Oxygen Demand?
500
Fleas spreading Bubonic Plague, for example.
What is a Vector?
