Q

Why are persistent organic pollutants persistent?

A
  • Synthetic, so environment doesn’t know how to deal w/ them and break the bonds
  • Harder for it to decompose in the environment
  • Starts chain reaction

However, DDT and other chemicals can be processed to be sequestered (NOT degraded)
* Sequester in fat of organisms (very ideal actually), or an organism that isn’t mobile
* when doing this, POP is still in the environment, but not degraded
* But it becomes a problem for the food chain, and therefore for people also

Q

How is DDT a chemical hazard

A

dichlorodiphenyl trichloroethane
* POP (mostly carbon)
* Toxicity is chronic (over a long period of time)
* Was marketed as non-toxic <3 wow silent spring! Not the person drinking a glass of ddt
* Downstream: impact on humans (reproductive), impact on birds (thinner egg shells :()
* Birds’ eggs are semi-permeable enough, but doesnt let important things leave
* If bird ingests worms or whatever na may DDT, thinner shells → not viable for incubation

Q

How is Tetraethyllead a chemical hazard

Study These Flashcards
A

used to be in our gasoline; impacts children
* Bc it attacks cognitive function

Lead deposits on bones & fat :( bc bodies are trying to grow so they deposit
* Body doesnt know what to do, so they store it in fat/bones
* If it affects fat, it affects brain bc brain is fat!

20
Q

How is radiation a chemical hazard

Study These Flashcards
A
  • Due to nuclear technology
  • Storage and disposal of nuclear waste; they store in lead
  • Lead blocks gamma radiation from nuclear, gamma radiation can alter human DNA
21
Q

How is solar radiation a problem

How does Vitamin D solve the problem

Study These Flashcards
A

UVB - causes sunburn; UVA - aging (breaks down collagen)
Sunburn
* When Skin cells are exposed to UVB, DNA starts being altered
* Skin cells are aware of alteration → let’s all kill each other so that mutation doesn’t spread to body
* Sunscreen saves skin cells

How do we get Vitamin D?
* A cholesterol in your body reacts with solar radiation, produces Vitamin D
* Reaction that happens when you’re exposed to the sun
* Good for calcium
* Immune system
* Fatty fish also!!

22
Q

How is the theory of biophilia important in envi psychology

Study These Flashcards
A

Theory of Biophilia
* Affiliation with nature comes from constant interaction with it
* Become an innate part of humanity

Studies how changes in the environment affects human well-being

23
Q

What’s the point of ecohealth?

Study These Flashcards
A

ecology x human health

  • Carrying capacity: Helped clarify human impact on ecosystems
  • Understanding links bet biodiversity and human health
  • Better understanding foundations of envi health
  • Ex. Vets are worried abt Swine Flu bc Pigs have similar systems with us
24
Q

health services for envi exposure i give up

Study These Flashcards
A
  • Occupational medicine: preventing hazard exposure
  • Broadened to gen envi exposure
  • Taking envi history & identifying at-risk grps
  • Providing treatment & preventive measures
  • Work ethics = interests of workers as well as employers
  • Clinical ecology treatments
  • Detoxification
  • Antifungal mediation
  • Dietary changes to help in effects of envi exposure
  • Problem: technically everything has risk
  • Cortisol: trending topic now
  • Hard to analyze(??) stress
  • Diff ppl handle stress differently, being exposed to same work can impact the 2 ppl differently
25
What are the pros and cons of the dolomite beach?
Pros 1. Aesthetic reasons, recreational activities (White: bring boracay to Manila Bay) 1. Less stress for small businesses → can sell stuff sa Manila Bay 1. Tried to salvage reputation of Manila Bay 1. Making green spaces more accessible Cons 1. Dolomite the mineral itself 1. Had to extract dolomite from somewhere else (Cebu), fucked the envi there just for Manila Bay 1. Heavy machinery operated on the beach 1. Mangroves in manila bay * no mangroves = Erosion * Mangrove holds soil * Replacing with looser materials increases erosion 1. Coastal erosion also needs to consider natural flow of the ocean
26
What are Emerging Issues in Environmental Health? | 3
1. Environmental Justice 1. Focus on Susceptible Groups 1. Global Change
27
How is environmental justice an important issue?
Environmentalism + public health + civil rights movement * Constitutional right to good environment Disproportionate exposure to hazards * Marginalized are more exposed Disparities in enforcement of environmental regulations * We have good laws on paper, problem is enforcement
28
Which susceptible groups should we target? | 4
1. Poor and minority populations 1. Children 1. Women 1. Elderly
29
Why should we focus on 1. Poor and minority populations 1. Children 1. Women 1. Elderly
30
Why should we focus on

34
Pros & cons of dolomite
Pros 1. Aesthetic reasons, recreational activities 1. White: bring boracay to Manila Bay 1. Less stress for small businesses → can sell stuff sa Manila Bay 1. Tried to salvage reputation of Manila Bay 1. Making green spaces more accessible Why do we hate it 1. Dolomite the mineral itself 1. Had to extract dolomite from somewhere else (Cebu), fucked the envi there just for Manila Bay 1. Heavy machinery operated on the beach 2. Mangroves in manila bay * Erosion: Mangrove holds soil; Replacing with looser materials increases erosion 10. Coastal erosion also needs to consider natural flow of the ocean
35
What are the Emerging Issues in Environmental Health | 3
Environmental **Justice** Focus on **Susceptible Groups** Scientific **Advances** Global** Change** Move towards **sustainability**
36
How is Envi Justice an important emerging issue?
Environmentalism + public health + civil rights movement * Constitutional right to good environment Disproportionate exposure to hazards * Marginalized are more exposed Disparities in enforcement of environmental regulations * We have good laws on paper, problem is enforcement
37
Which Susceptible Groups should we focus on?
Poor and minority populations Children Women Elderly
38
How are Poor and minority populations susceptible?
* Limited access to legal protection and medical care * Compromised borderline health status
39
How are children susceptible?
* Ingest more per unit of body weight * Behavioral differences * Developing systems and organs
40
How are women susceptible?
**Disproportionate exposures and unique susceptibilities** * Hips & breasts * Breastfeeding up to 2 years old * Bc need more fat for brain development, breast milk has more fat (30-33% fat) * If kids’ brains wre fully developed at birth, mom can’t bring out baby * After theyre birthed, they need to fully develop their brain
41
How are Elderly susceptible?
Specific risks that come with age
42
How are Scientific Advances an important emerging issue?
1. Toxicology: better detection limits and innovative 1. techniques 1. GIS for spatial distribution 1. Genomics * Toxicogenomics (gene and protein activity as a response to a toxic substance)
43
What are some Global Changes? 5
* Population growth * Climate change * Urbanization * Changing patterns of energy use * Increasing integration of the world economy
44
Explain how climate change can impact envi
Ex. dengue & malaria Usu happens in tropics, tropics will expand over time, then europeans will have dengue and malaria
45
How is Increasing integration of the world economy impacting envi?
* Hazards crossing national boundaries * Trade agreements & market forces undermining envi health policies * Ex. canada sending us their trash
