farms & the
food we grow
Our oceans, lakes,
and rivers
ALL the places we
live, work & play

Exposure is
The total amount of a hazard that comes
in direct contact with your body.
Integrated Environmental Health Middle School Project • University of Washington © 2005 16
The 3 parts of exposure
The
Source
of the hazard
(bus exhaust)
The
Environmental
Pathway
(air)
The
Contact
(inhaled fumes)
Integrated Environmental Health Middle School Project • University of Washington © 2005 17
Which route will the hazards take?
Integrated Environmental Health Middle School Project • University of Washington © 2005 18
Route #1: Inhalation
Inhalation:
Breathing. When
chemicals enter the
body through this
route of exposure,
they can get stuck in
the lungs and/or be
taken up into the
bloodstream.
Integrated Environmental Health Middle School Project • University of Washington © 2005 19
Route #2: Ingestion
Ingestion:
Swallowing (usually
by eating or drinking).
When chemicals enter
the body through this
route of exposure,
they can easily be
taken up into the
bloodstream.
Integrated Environmental Health Middle School Project • University of Washington © 2005 20
Route #3: Dermal Absorption
Dermal Absorption:
Absorbing a chemical through any part of the skin, including
the eyes. When chemicals come in contact with the skin, they
can sometimes enter the bloodstream through this route of
exposure.
Integrated Environmental Health Middle School Project • University of Washington © 2005 21

Integrated Environmental Health Middle School Project • University of Washington © 2005 23
Dose can depend on…
Duration of
Exposure:
How long?
Frequency of
Exposure:
How often?
Body Size:
How big or
small are you?
M

S S
Integrated Environmental Health Middle School Project • University of Washington © 2005 24
Duration of Exposure
might not have
any harmful
effects.
30 minutes of
sun exposure
Integrated Environmental Health Middle School Project • University of Washington © 2005 25
Duration of Exposure
might be very
harmful indeed!
But 4 hours of
sun exposure
Integrated Environmental Health Middle School Project • University of Washington © 2005 26
Dose can depend on how big or
small you are. To understand how,
let’s take three different size flasks
and fill them with water. Imagine
each one represents a different
human body - one small, one
medium, and one large.

Now we will take a
dropper of an imaginary
hazardous substance and
put 3 drops in each flask.
What will happen? How
will each flask look after
the 3 dark purple drops
have been added?

The larger the dose, the more extreme
the response will be.

Individual Susceptibility
Why are these people
more likely to be
harmed by exposure to
a hazard than the man
below?
Integrated Environmental Health Middle School Project • University of Washington © 2005 34
Individual Susceptibility
Pregnant women
and their
developing
babies
Elderly people
whose defense
mechanisms are
less efficient
Infants and
children who
are still
developing
Sick people who
have weakened
immune
systems
Integrated Environmental Health Middle School Project • University of Washington © 2005 35
Genes & Susceptibility
Your genes can also
make you more or less
susceptible to harm
from an environmental
hazard. For example,
some people are more
likely to get sick when
they are exposed to
certain kinds of
pesticides.

Risks & Benefits
What are the risks and benefits when grape
growers use pesticides on their crops?
Integrated Environmental Health Middle School Project • University of Washington © 2005 39
Risks & Benefits
RISKS
BENEFITS
•No bugs!
•Better looking fruit
that is more visually
appealing
•Bigger crops so
farmers can make
more profit
•People ingest
pesticides with the
fruit and get sick
•Pesticides get into
dirt and water
•Animals ingest
pesticides and get sick
Integrated Environmental Health Middle School Project • University of Washington © 2005 40
Integrated Environmental Health Middle School Project • University of Washington © 2005 41
What is environmental justice?
Environmental
Justice (EJ) means
that everyone has a
right to live in an
environment that
doesn’t make them
sick, regardless of
their race, culture, or
income.
Integrated Environmental Health Middle School Project • University of Washington © 2005 42
The EJ Process
Who is
producing
the hazard?
Who is being
exposed?
Who are the
decision
makers?
Establish a dialog
between the
decision makers,
scientists, and the
affected
community.
Empower
community
members to bring
about change.
Share information
and decisions with
community
members.
Integrated Environmental Health Middle School Project • University of Washington © 2005 43
Integrated Environmental Health Middle School Project • University of Washington © 2005 44
Where can you go for information?
City hall
State agencies
Federal agencies
Doctors
Nurses
Hospitals
Health Department
Schools
Libraries
Universities
Caution!
Integrated Environmental Health Middle School Project • University of Washington © 2005 45
How can you take action?
Write a letter to
a newspaper
Call or write an
elected official
Organize a
community
meeting
Inform your
neighbors
Make a
documentary about
the problem
Create a petition
and get
signatures

  • 18. Integrated Environmental Health Middle School Project • University of Washington © 2005 18 Route #1: Inhalation Inhalation: Breathing. When chemicals enter the body through this route of exposure, they can get stuck in the lungs and/or be taken up into the bloodstream.
  • 19. Integrated Environmental Health Middle School Project • University of Washington © 2005 19 Route #2: Ingestion Ingestion: Swallowing (usually by eating or drinking). When chemicals enter the body through this route of exposure, they can easily be taken up into the bloodstream.
  • 20. Integrated Environmental Health Middle School Project • University of Washington © 2005 20 Route #3: Dermal Absorption Dermal Absorption: Absorbing a chemical through any part of the skin, including the eyes. When chemicals come in contact with the skin, they can sometimes enter the bloodstream through this route of exposure.

  • 23. Integrated Environmental Health Middle School Project • University of Washington © 2005 23 Dose can depend on… Duration of Exposure: How long? Frequency of Exposure: How often? Body Size: How big or small are you? M L S S
  • 24. Integrated Environmental Health Middle School Project • University of Washington © 2005 24 Duration of Exposure might not have any harmful effects. 30 minutes of sun exposure
  • 25. Integrated Environmental Health Middle School Project • University of Washington © 2005 25 Duration of Exposure might be very harmful indeed! But 4 hours of sun exposure
  • 26. Integrated Environmental Health Middle School Project • University of Washington © 2005 26 Dose can depend on how big or small you are.

  • 34. Integrated Environmental Health Middle School Project • University of Washington © 2005 34 Individual Susceptibility Pregnant women and their developing babies Elderly people whose defense mechanisms are less efficient Infants and children who are still developing Sick people who have weakened immune systems
  • 35. Integrated Environmental Health Middle School Project • University of Washington © 2005 35 Genes & Susceptibility Your genes can also make you more or less susceptible to harm from an environmental hazard. For example, some people are more likely to get sick when they are exposed to certain kinds of pesticides.

  • 41. Integrated Environmental Health Middle School Project • University of Washington © 2005 41 What is environmental justice? Environmental Justice (EJ) means that everyone has a right to live in an environment that doesn’t make them sick, regardless of their race, culture, or income.
  • 42. Integrated Environmental Health Middle School Project • University of Washington © 2005 42 The EJ Process Who is producing the hazard? Who is being exposed? Who are the decision makers? Establish a dialog between the decision makers, scientists, and the affected community. Empower community members to bring about change. Share information and decisions with community members.
