Module 5 Flashcards
What are some environment health problem
Air pollution, chemical pollutions, and unclean water
What is an example of precautionary principle
Enforcing mask mandate in certain places without direct evidence or scientific reasoning
Distinguish the impact of cell death versus cell damage
Cell death has a lesser concern compared to cell damage with no further implications, while cell damage has more prominent implications like mutations, birth defects, or cancer
What are three environmental hazards that cause birth defects
PCBs, dioxins, and pesticides
What is DES and its adverse health effect associated with it
Diethylstilbestrol (DES) is a synthetic form of female hormone estrogen (was used by pregnant women to prevent miscarriages)
Adverse health effect associated is vaginal cancer in women, birth defects, congenital deformities of the reproductive system, reduced fertility, and miscarriages
What is DBCP and the adverse health effect associated with it
1,2, dibromo-3-chloropropane (DBCP) is a liquid soil fumigant.
The adverse health effect associated reduces sperm production or the chemical composition of semen.
What are two lung diseases that are classified as a “pneumoconiosis”
Black lung (silicosis) - occurs when dust like cold dust is inhaled scarring the lungs
Asbestosis- occurs from inhaling asbestos fibers
What did Sir Percival Plott’s contribute to public health
The first doctor to identify some environmental factor causing cancer
What are two carcinogens typically associated with exposure in the work environment
Benzene and asbestos
What are two adverse health effects/ outcome associated with fetal alcohol syndrome
Facial abnormalities
Growth defects (non-developing brain, small in size)
What are three sources of environmental hazardous noise
Leaf blowers, aircraft, car traffic
What are four adverse health effects and outcomes associated with hazardous noise
Nosie-induced hearing loss
Low reading skills
Tinnitus (ringing in ears)
Metabolic changes (increase heart rate)
What are two interventions implemented to address exposure to aircraft noise
Introduction of quieter planes
Lighter aircraft
What are two sources of noise for which children and young adults are more likely exposed; list one potential intervention to address the problem
Noisy classroom- investing in noise-cancelling headphones
Precautionary Approach to Addressing Hazards (Hierarchy of controls)
Elimination (most effective)- getting rid of the hazard altogether
Substitution- replacing one substance or activity with a less hazardous one
Engineering- improving ventilation, physical barriers around machinery
Administrative- policies and procedures to reduce opportunity for exposure
Personal Protective Equipment (least effective) -hard hats, gloves, ear plugs
