2What is Mercury?
- Known as quicksilver
- A naturally occurring element in oceans, rocks
soils - Liquid at room temperature
- Used in a variety of products
- Toxic persistent in the environment
3What are the sources of Mercury pollution in MN?
- Energy 51
- Taconite processing 21
- Purposeful use 28
- Municipal solid waste combustion 5
- Volatilization of disposed products 7
- Smelters that recycle cars, appliances 5
- Coal fired Power plants 46

5Mercury Products
- Fluorescent high intensity discharge lamps
- Thermostats switches
- Thermometers
- Steam irons with 15-minute automatic shut-off
- Dental amalgam
- Old alkaline batteries, some button batteries
- Old latex paints (pre 1990) some oil based
paints
6Number one source of mercury exposure for humans
is fish consumption.
7Bioaccumulation
- Mercury is deposited in lakes where bacteria
convert it to toxic methylmercury (MeHg) - MeHg is taken up by tiny animals and plankton
- MeHg then accumulates in the tissues of fish and
other organisms - Wildlife like eagles, osprey, loons, turtles,
mink, otters and other fish-eaters are also
affected - All Minnesota waters contaminated.
8Who is at the top of the food chain?
9Problem with Methylmercury
- Potent neurotoxin.
- Like lead, mercury effects are being detected at
lower and lower levels. - MeHg passes through the placenta to the
developing fetus and is also passed on to nursing
infants in breast milk.(Breastfeeding is still
best for babies.)
10Newborns at Risk
- Per new EPA estimates
- 1 in 6 U.S. women has mercury body burden that
could put her baby at risk for adverse effects on
development - could affect an estimated 630,000 newborns a year
11Fish are Healthy
- Source of protein, vitamin D omega-3 fatty
acids - Essential for fetal and infant brain development
- Contribute to heart and mental health
Dont stop eating fish!
12What can we do?BE SAFE-Heed Early
Warnings-Put Safety First -Choose the Safest
Solutions -Exercise Democracy
13Heed Early Warning Signs
- Testing by the Minnesota Department of Natural
Resources shows that mercury is present in 100
of lakes and fish tested. - Mercury is a known neurotoxin and rates of
children with learning disabilities are on the
rise. - There should be more public awareness about the
risks of eating certain fish and more efforts to
eliminate the contamination.
14Put Safety First
- Public health policy that asks expectant mothers
to give up certain foods while allowing
industries to continue contaminating them is
absurd. Sandra Steingraber

15Choose the Safest Solutions
- Clean Energy
- Mercury Free Products
16Smart Fish Choices
- Follow these guidelines
- Eat smaller fish, panfish
- rather than predator fish
- Consider total fish consumption
- Limit intake of some fish for pregnant/nursing
women and young children. - Trimming fat and cooking will not reduce mercury
in fish.
17What about canned tuna?
- Canned white albacore has 3-4 times more
mercury than chunk light - Women of childbearing age can eat 8 oz a week of
canned chunk light - Younger children can eat about ½ can of chunk
light tuna per week. - Women of childbearing age kids under 15 should
limit canned white albacore tuna to once a
month

guidelines - Go to www.iatp.org/foodandhealth
19Reduce your Use
- Conserve energy to reduce electricity demand
- Replace mercury thermometers with digital ones
- Purchase mercury-free thermostats, switches
- Use mercury free batteries
- Ask your dentist for non-mercury amalgams
- Dispose of all mercury products as hazardous
waste, find information for your county at
www.moea.state.mn.us/hhw/programs.cfm
20Buy Wind Power
- Replace fossil-fuel based energy with renewable
sources like solar wind - Support renewable energy by choosing wind power
from your local utility
21Exercise Democracy
- Tell the MN Pollution Control Agency to protect
us from mercury. - Tell the FDA to issue adequate mercury warnings.
- Vote!
22Federal Laws and Regulations on Mercury Pollution
- Current administration proposals delay
significant mercury reductions for 10 years. - Clean Air Act - 90 reduction by 2008
- Clear Skies Initiative - 69 reduction by 2018
- Proposed MACT rules for coal plants align with
Clear Skies and allow 7X Hg pollution of Clean
Air Act
