time of exposure to a substantial dose of toxicant
Chronic toxicity Right Ans - prolonged or frequently repeated exposure to
lower toxicant doses, effects not generally observable immediately following
the exposure and may take very long periods to produce signs and symptoms
Hazard Right Ans - the possibility that injury will result from the use of a
substance in a given formulation, quantity, or manner (Hazard = Toxicity x
Exposure)
A pesticide may be extremely toxic but can present little hazard if: Right
Ans - - in very dilute form
- in formulation not readily absorbed through skin or not able to inhale
- used occasionally and in conditions where humans aren't exposed
- used by experienced applicators properly equipped
A pesticide may be low in toxicity but present a hazard because it is: Right
Ans - - used in concentrated form
- rapidly absorbed or inhaled
- used frequently by untrained or careless persons, who became exposed to it
Oncogenicity Right Ans - ability to cause tumors, not necessarily cancer
Teratogenicity Right Ans - ability to cause birth defects
Mutagenicity Right Ans - ability to cause gene defects
Carcinogenicity Right Ans - ability to cause cancer
LD Right Ans - lethal dose based on single exposure to chemical
, LC Right Ans - lethal concentration of pesticides in the air (mostly
fumigants)
Ocular exposure Right Ans - type of dermal exposure: penetration through
eyes
Readily absorbed through skin Right Ans - solvents and liquid formulations
such as emulsifiable concentrates (contain high % of a.i. in small amount of
solvent)
Most common route of pesticide exposure for applicators Right Ans -
absorption through skin (dermal exposure)
Parts of skin that most rapidly absorb pesticides Right Ans - genitals
thinner areas of skin
forehead
break in skin
burns
dermatitis
eczema
Minimum interval before people without PPE can be on application site of
liquid pesticides Right Ans - length of time it takes for the application to
dry
Oral exposure Right Ans - ingestion of pesticide liquid or dust during
mixing and application
Avoid oral exposure by: Right Ans - storing pesticides in original labeled
containers
keep food and beverages away from pesticides
do not blow into nozzles to clean them
