Massachusetts Core Supplement Prep
Exam Questions Fully Solved.
Define Mutagen - Answer A substance or agent able to cause genetic changes in living cells
Define Oncogen - Answer A substance or agent able to induce tumors (not necessarily cancerous) in
living tissues
Define Carcinogen - Answer A substance or agent able to produce malignant tumors (cancer)
Define Teratogen - Answer A substance or agent able to produce abnormalities or defects in living
human or animal embryos and fetuses. These defects are not usually inheritable
Define Neurotoxin - Answer A substance or agent able to cause disorders of the nervous system
Explain why chronic health effects are more difficult to diagnose than acute health effects - Answer
Recognition of chronic health effects and development of scientific methods to screen chemicals for such
effects have been slower to develop than was the case for acute toxicity
-Consequently less in known about chronic health risks and there are more areas of disagreement on
how to conduct and interpret such tests
List the resources where you can find information about the chronic health effects associated with the
pesticides that you are using - Answer -Read the label
-Chemical safety data sheets
-National pesticide information center
-U.S. EPA pesticides program
Define Cholinesterase - Answer An enzyme that regulates nerve impulses in humans and many other
animals
, Define Organophosphate - Answer A large group of insecticides, miticides, and nematicides that
contain the element phosphorus and are cholinesterase inhibitors
Define Carbamate - Answer A group of cholinesterase-inhibiting pesticides used to control insects,
mites, and nematodes
How to handle an exposure incident involving organophosphate and carbamate - Answer -remove
contaminated clothing
-wash area well with soap and water
-contact physician
-bring copy of the label and this sheet with you
-For more info contact MA poison information center
List plants and/or sites where you may see bees foraging - Answer -Flowers
-Plants shedding pollen
-Plants producing nectar
-Plants in bloom
-Weeds in bloom
Identify the primary section of the label where bee toxicity information is located - Answer
Environmental Hazards Section
Compare pesticide formulations that are more toxic to bees to formulations that are less toxic to bees -
Answer -Most hazardous type is microencapsulation where the active ingredient is encased in tiny
nylon type plastic capsules
-Dusts are more hazardous than sprays
-Wettable powders usually provide a significant longer toxic hazard than EC because the dry particles
cling better to the body hair of foraging bees
Discuss how temperature can affect the impact of pesticides on bees - Answer -Honey bees can
become active and forage at temps as low as 55f
-Temp has a significant modifying effect ono the bee-poisoning hazard of a pesticide
