Week 30 environmental health practice Flashcards
What are the triggers for disease? THINK CH2OPD
- Community - environmental exposures, air water,
- Home, hobbies
- Occupation (school, university)
- Personal exposures
- DIet
what is the AQHI
a measure of the air qua lity
3 - low risk
10 - high risk
Short-term exposure to air pollutants can lead to…
- Exacerbation of pre-existing respiratory disease (asthma, COPD)
- Exacerbation of pre-existing CVD (ischemia, cardiac failure, arrhythmia, Ischemic stroke)
Long-term exposure to air pollutants
- Increased mortality
- Development of atherosclerosis (inflammation)
- Pregnancy effects (shorter pregnancy)
- New onset of asthma
- Reduced lung function growth
Who is at risk from air pollutants? susceptibility/exposure 6 things
- People with existing heart and lung disease
- Diabetics (pro-inflamm state)
- young children (more outdoors, and more susceptible lungs)
- the elderly
- People who are active outdoors
- Some members of the general population
What are the three pollutants used for AQHI ?
- Ozone
- NO2
- PM2.5
What are two factors that are importantly increasing with respect to climate change
- Humidity
- Sea surface temperatures
- Ocean heat content
What are direct health impacts of climate change?
- Temperature-related
2. Extreme weather events
What are indirect health impacts of climate change?
- Air pollution related
- Vector and zoonotic diseases
- Increase scarcity of food and fresh water
- Rise in sea level
- loSS IN biodiversity
- Areas becoming uninhabitable
- Mass human migration, conflict and violence
What are the health co-benefits of low carbon policies in the transportation sector?
less air pollution
Active transportation, exercise
What are the health co-benefits of low carbon policies in the food/agri sector?
eat lower on the food chain - produce less carbon dioxide
What are the health co-benefits of low carbon policies in the electricity generation sector?
less Air pollution
