QUESTIONS AND CORRECT DETAILED ANSWERS WITH RATIONALES
Chronic health effect - correct answer Problems that develop over a relatively

problem, or following a series of small exposures which accumulate in some
manner and result in a development of a disease or disorder
acute toxicity - correct answer Poisoning from a single dose over a much shorter
duration of time
How soon do health effects occur from accrue toxicity? - correct answer Within
24 hours of exposure
Chronic health risk problems (major examples) - correct answer Mutagenicity,
oncogenicity, carcinogenicity, teratogenicity, neurotoxicity

answer Faster and cheaper than animal lifetime testing
Oncogenicity - correct answer The ability of a chemical to cause abnormal
growths or tumors in tissues
Carcinogenicity - correct answer Ability of a substance or agent to cause
malignant tumors
How do they test chemicals for their ability to cause tumors - correct answer

female test animals at various stages of pregnancies and observing number of
miscarriages and defective offspring verses what would normally be expected
Examples of animals used to test teratogenicity - correct answer Rodents,
rabbits, dogs, monkeys
Effects of chemicals are usually considered significant for teratogenicity if... -
correct answer They occur at doses not toxic by themselves to the mother
Testing for teratogenicity is standard part of pesticide registration although
___________ May exist for older chemicals - correct answer Data gaps

not refer to reversible effects
Test animal for neurotoxicity - correct answer Chicken

QUESTIONS AND CORRECT DETAILED ANSWERS WITH RATIONALES
Cholinesterases - correct answer Enzymes found in humans, insects, and other
species that are necessary for normal function of the nervous system
What kind of insecticides can block or inhibit cholinesterases - correct answer
Organophosphates, carbamates
How much exposure to cholinesterase blocking pesticides does it take to make
you feel sick - correct answer Depends on type of product, potency of active
ingredient, amount of exposure, whether you're handling concentrated or diluted
mixture
Effects of exposure to cholinesterase blocking pesticides - correct answer May
range from no observable effects to severe illnesses or symptoms requiring
hospitalization. Severe poisoning can lead to coma or death
When do symptoms occur after exposure to cholinesterase blocking pesticides -
correct answer Anywhere from time of exposure to 12 hours

answer Nausea, vomiting, diarrhea, tightness in chest, excessive sweating, rapid
heartbeat, cramps, restlessness, headache, confusion
Poisoning from organophosphates or carbamates can resemble... - correct
answer Drunkenness, head cold, flu
Why monitor cholinesterase levels - correct answer To establish a baseline for
normal activity and be alerted to any drop in enzyme levels before they reach
values low enough to make you sick. Changes can be detected in absence of
symptoms. Workers can be removed from exposure before symptoms occur
Natural recovery from cholinesterase blocking pesticides exposure normally
occurs... - correct answer When exposure stops
Who should have their cholinesterase levels monitored? - correct answer People
who regularly use organophosphates and carbamates
What should you do if you are inadvertently exposed to cholinesterase blocking
pesticides - correct answer Remove contaminated clothing. Wash area well with
