KEY THEMES OF THE COURSE:
- We make the world we live in and we live in the world we makes
- People living in a modern western lifestyle create, use, and dispose of lots of stuff ; the stuff
and its byproducts are transported/transformed, but never disappear.
- In an ecosystem, nothing ever goes away
- Often lack of foresight in adopting new products & technologies.
- Natural evnt – global; trade & travel are increasingly globalized
- Global disparities in development and health are enormous; Western-style development is
NOT sustainable @ global scale.
Your environment is your health
• Environment = everything that affects a living organism
• Effects of envt on human health is so great
o Air
o Water
o Soil
o Biota
o Manmade envt
• Genetics also affect human health greatly; GENE-ENVIRONMENT INTERACTION
o Genetics increase exposure to an envtal risk factor (how much u receive)
o Increases susceptibility to an envtal risk factor (more sensitive/prone to illness)

o Genetics and envtal factor are INDEPENDENT risk factors (but they interact)
• What is Environmental Health?
o According to WHO (world health org) - I its roadest sese, eiroetal health
comprises those aspects of human health, disease, and injuries that are determined or
iflueed y fators i the eiroet
o Iludes stude of oth direct and indirect pathological effects of various: chemical,
biological, physical (only man-made: hoursing, urban development, urban,
transportation)
o The Scope of envtal health
o CORE CONCERNS:
▪ Focus on chemical, biological, physical hazards
▪ Interactions w/genetic traits w/ social/behavioral stressors
▪ Emphasis on anthropogenic hazards
▪ MORE THAN POLLUTION – have to know broad science (all integrated)
▪ Very human-centric – branch on public health takes a population perspective
Have to be a significant amount of people
TYPES OF HAZARDS:
1. Chemical hazards – in air, water, soil, and food
(E.g. Pesticides, mercury, GMO (genetically modified), DDT (chlorinated, bifenials toxins)
2. Biological Hazard – Bacteria, virus, parasites, allergens, animals
(E.g. bees-venom/stings, snakes-venom, mosquitoes- Malaria, pigs –H1N1)
3. Physical Hazard – focusing on man-made ; buildings and roads
