RE: Removal of Mercury from Schools
Last
session the Maine Legislature passed a law
(PL 2001, c 373, §3) banning the sale of mercury and mercury compounds
for use in primary and secondary classrooms.
The Legislature took this action, in part, because mercury is a
neurotoxin that can impair brain development, and young children are at
particular risk. A recent report by the
National Academy of Science suggests mercury exposure may cause learning
disabilities in over 60,000 U.S. children each year. Similar legislation was enacted in New Hampshire and Rhode
Island, and is pending in other states.
Historically, schools have been a place
where mercury and children have come together.
The new law will help eliminate some of the opportunity for contact
because it is aimed at keeping elemental mercury and mercury compounds such as
mercurous azide, mercuric chloride or mercury oxide, out of the classroom.
However, the new law does
not entirely eliminate the potential for exposure. Manufacturers can still sell products with mercury components,
such as non-fever thermometers and barometers, and breakage of these
instruments is a common cause of school mercury spills. Even small spills have lead to unacceptable
human exposures and forced school closures during cleanup. Cleaning up a mercury spill from a
wall-mounted barometer caused one Maine high school to shut down for two days
last spring and cost about $20,000 to clean up.
Consequently, some schools
have decided that keeping mercury instruments in the classroom is not worth the
risk, and they have replaced them with mercury-free alternatives. When your school decides to replace any
mercury-containing item, we urge you to follow their lead.
We also encourage you and
your staff to check for mercury in your school and, if found, to arrange for
proper recycling or disposal. For help in conducting a mercury audit,
becoming a mercury-free school, or guidance on your recycling and disposal
options, please contact Ann Pistell of the Department of Environmental
Protection at 287-7703 (email ann.e.pistell@state.me.us
).
Two good resources for more
information on mercury in schools are the web sites of the University of
Wisconsin, (http://www.mercury-k12.org)
and the Michigan Department of Environmental Quality (http://www.deq.state.mi.us/ead/p2sect/mercury/schools.html). The first site also offers curricula that
can be used to teach students about the problem of mercury in the environment.
Thank you for your help in
tackling this problem. We welcome your efforts to educate young Mainers about the dangers of mercury, to
reduce their risk of exposure to mercury in the classroom, and to ensure that
schools are not a source of mercury emissions to our environment.
