Study These Flashcards
A

The result of a pathogen invading a body

22
Q

LD50

Study These Flashcards
A

The poing at which 50% of the test organisms die from a toxin LEACHATE - the liquid that percolates to the bottom of a landfill

23
Q

Low-level Radioactive waste

Study These Flashcards
A

Radioactive wastes that produce low levels of ionizing radiation

24
Q

Noise Pollution

Study These Flashcards
A

Any noise that causes stress of has the potential to damage human health

25
Non-point source pollution
Pollution that does not have a specific point of release
26
Open-loop recycling
When materials are reused to from new products
27
Ozone Holes
The thinning of the ozone layer over Antarctica (and to some extent, over the Arctic)
28
Pathogens
Bateria, virus, or other microorganisms that can cause disease
29
Photochemical Smog
Usually formed on hot, sunny days when NOx compounds, VOCs, and ozone combine to form smog with a brownish hue
30
Point source pollution
A specific location from which pollution is released; e.g., a factory where wood is being burned
31
Poison
Any substance that has an LD50 of 50 mg or less per kg of body weight
32
Physical Treatment
In a sewage treatment plant, the initial filtration that is done to remove debris such as stones, sticks, rags, toys, and other objects that were flushed down the toilet
33
Primary Pollutants
Pollutants that are released directly into the lower atmosphere
34
Primary Treatment
When physically treated sewage water is passed into a settling tank, where suspended solids seperate and settle out
35
Risk Assessment
Calculating risk, or the degree of likelihood, that a person will become ill upon exposure to a toxin or pathogen
36
Risk Management
Using strategies to reduce the amount of risk; e.g., the likelihood that a person will become ill upon exposure to a toxin or pathogen
37
Secondary Pollutants
Pollutants that are formed by the combination of primary pollutants in the atmosphere
38
Secondary Treatment
The biological treatment of wastewater in orfer to continue to remove biodegradable waste
39
Sick Building Syndrome
A condition in which the majority of a building's occupants experience certain symptoms that vary with the amount of time spent in the building, without being able to identify a specified cause or illness
40
Sludge
The solids that remain after the secondary treatment of sewage
41
Sludge Processor
A tank filled with aerobic bacteria that's used to treat sewage
42
Solid Waste
Can consist of hazardous waste, industrial solid waste, or muncipal waste; many types of solid waste provide a threat to human health and the environment
43
Stationary Sources
Non-moving sources of pollution, such as factories
44
Superfund program
A program funded by the federal government and a trust funded by taxes on chemicals; identifies pollutants and cleans up hazardous waste sites
45
Threshold dose
The dosage level of a toxin at which a negative effect occurs
46
Toxicity
The degree to which a substance is biologically harmfull
47
Toxin
Any substance that is inhaled, ingested, or absorbed at dosages sufficient to damage a living organism
48
Tropospheric Ozone
Ozone that exists in the troposphere
49
U.S. Noise Control Act
Gave the EPA power to set emission standards for major sources of noise, including transportation, machinery, and construction
50
Vector
The carrier organism through which pathogens can attack, such as a tick
51
Wastewater
Any water that has been used by humans; this includes human sewage, water drained from showers, tubs, sinks, dishwashers, washing machines, water from industrial processes, and storm water runoff
52
Waste-to-Energy (WTE) Program
When the energy released from waste incineration is used to generate electricity
