Identifying and determining probability, severity and consequences
What is risk assessment?
100
Give 3 examples of environmental consequences
loss of BD, habitat fragmentation, pollution of any kind, ozone depletion, more GHG's --> global warming, habitat destruction, etc.

Molecules are absorbed into tissues of organisms at levels higher than expected.
What is bioaccumulation?
100
The study of Toxicants or toxic chemicals.
What is Toxicology?
100
The amount of damage to human health.
What is response?
200
Weighing the benefits versus the risk
What is risk benefit analysis?
200
Which of the following is NOT an environmental risk:
A) habitat fragmentation
B) loss of revenue
C) loss of biodiversity
D) increase in CO2 emissions
B) --> this is an economic risk

DOUBLE JEOPARDY! (click + twice for correct response)
The median lethal dose: the amount of a chemical received in one dose that kills exactly 50% of the living things tested
What is LD 50?
200
Two ways of determining if a chemical causes cancer.
What are Toxicology and Epidemiology?
300
Possibility of suffering harm from a hazard that can cause injury, disease, economic loss, and environmental problems

Located more toward the upper left corner of a Dose-Response curve.
What is the more toxic substance?
300
Long-term, low dose exposures to chemicals that damages vital organs.
What is chronic toxicity?
300
A chemical mixture the produces a lower reaction than would result from the sum of each of the components acting indivually.
What is Antagonistic interreaction?
400

400
Something that has an LD 50 of 50mg or less
What is Poison? (In regards to LD 50.)
400
The safe level of exposure below which chemical's harmful effects are insignificant.
What is the Threshold Level?
500
identification, assessment, and prioritization of risks followed by coordinated and economical application of resources to minimize, monitor, and control the probability and/or impact of unfortunate events
What is risk management?
500
A toxic reaction that occurs immediately or within several days of exposure.
What is Acute Toxicity?
500
A chemical mixture that results in increased effect than the sum of the individual components.
What is a Synergistic mixture?
500
Lower weight, playing on floors, putting things in their mouths, and less development.
