Contact Your Reps Now!

By Dominique Browning of the Moms Clean Air Force

I don’t want to nag, though we all know moms are great at that. But I’m going to remind everyone that as of Monday, August 1, we have only FOUR MORE DAYS to write to the EPA  in support of their NEW Mercury and Air Toxics Standards. This regulation will cut down the poisonous emissions from coal-fired electric plants. Fetuses, infants and toddlers are especially vulnerable to the harmful effects of toxic coal pollution.

Pro-polluters have been working overtime to cut funding for the EPA and block anti-pollution regulations. They’re spending millions of dollars on lobbying and campaign contributions–to protect their right to pollute!

Motherhood is powerful too.  We have to make our voices heard.

Someday your children will thank you. Right now, you have to fight for them. My A Number One Reason will always be the same: my two beloved sons, for whom I will always fight like a mama bear, Alex and Theo. I’ll bet you feel the same way about yours.

Here is a GREAT REASON to write to the EPA now.

1.  YOUR VOICE MATTERS. No politician wants to make a mom mad. The EPA needs to hear that you want it to protect your right to clean air. Sometimes being a great mom means being an active citizen.

2.  WE’VE MADE IT EASY–AND YOU CAN FIND THE TIME. It is faster to write to the EPA than it is to change a diaper. Sometimes being a great mom means being an active citizen. Make your voice heard!

3.   POLLUTION CONTROL MEANS MORE JOBS. Green jobs are rising dramatically. Retrofitting coal stacks with scrubbers means more jobs for people in the industry–and a stronger industry overall.

4.   HOW DARE THEY HARM OUR BABIES! Fetuses, infants and toddlers are especially vulnerable to the harmful effects of toxic pollution. Childhood cancers are on the rise. So are asthma attacks.  Pregnant women are warned against eating tuna fish because it is full of mercury. And polluters keep on fighting for their right to pollute.

I’m Getting my Hair Tested

For mercury, that is.  The Sierra Club is holding free mercury testing events throughout the country, but of course there aren’t any around here.  Fortunately they’re also offering testing by mail for a small fee.  All I need to do is send in a small sample of my hair.  (Of course with my hair, no sample is that small…)

The results of the mercury test will be valuable for a few reasons.  As everyone knows, I’m a breastfeeding mom and mercury has been found in human milk.  However, the risks of mercury exposure through nursing are less than the risks associated with NOT breastfeeding, so I’m not really concerned about that.  However, mercury in a mother’s blood can easily cross the placenta and concentrate in a developing fetus, and I do want to have more children someday.  I also love to eat seafood, especially fish that Ed catches, so that’s another reason to get tested.  Once I know my mercury level, I’ll be able to make educated choices about what I eat and future pregnancies.

But I really want to get my hair tested because I’m a science nerd.  I’m excited for the same reasons I loved getting tested for carrier status of common genetic disorders when I was pregnant.  I read about or even teach about these tests, so it’s neat to get them done myself.  I just like to know the results, and I’ll enjoy talking about it with my friends as well as using it as a teachable moment with my students.  It will also give me some data to share when I argue in favor of regulating mercury emissions.

Would you get your hair tested for mercury, or would you prefer not to know?

Mercury Pollution: What Parents Need to Know

My dad tells a story of his science teacher handing out vials of mercury and allowing students to play with it and watch how it pools.  Those days are gone! (I should know, I’m a science teacher.)  Today, we aren’t even allowed to have mercury thermometers in school, and there are news reports of schools being evacuated due to a broken thermometer.  We now know that mercury is toxic to kids.

Mercury as an atmospheric pollutant comes mostly from power plants, with 72% of it coming from coal-fired power plants.  Once released into the atmosphere, mercury contaminates entire ecosystems: fresh and salt water, soil, the substrate at the bottoms of streams, rivers, lakes and oceans, as well as plants an animals.  Microorganisms in the water convert mercury to the highly toxic methylmercury.  Methylmercury accumulates in the tissues of animals, especially salt water fish like sharks, swordfish and tuna.

Here’s what I think all parents should know about mercury pollution:

  • 1 in 10 American women of childbearing age have potentially dangerous levels of mercury in their bodies.
  • 410,000 US children are exposed to dangerous levels of mercury in the womb each year.
  • 95% of the methylmercury we consume is absorbed through our small intestines and enters our bloodstream, which carries it to the rest of our body.  It will eventually be excreted over a period of weeks to months.
  • Methylmercury easily crosses the placenta and travels into a fetus’s blood and organs, including his or her brain.
  • Methylmercury levels in an unborn child’s blood can accumulate to be higher than the levels in his or her mother’s blood.
  • Mercury in both the form of methylmercury (from seafood) and inorganic mercury (from amalgam fillings) has been found in breast milk in studies around the world. However, the level of mercury in a mother’s blood are about 3 times higher than the level of mercury in her milk, so babies are exposed to much more mercury in utero than through breastfeeding.  Experts say that the benefits of breastfeeding outweigh the risks of mercury exposure.
  • Infants can be exposed to mercury through formula if it is prepared with water contaminated with methylmercury, so experts recommend breastfeeding over formula-feeding in areas with contaminated water.
  • Methylmercury exposure leads to impaired neurological development in fetuses, infants and children.  It can also delay developmental milestones and cause severe mental disabilities.

The Clean Air Act does not currently have limits on the amount of mercury that can be emitted by power plants, but the EPA would like to set a new Mercury and Air Toxics rule to reduce the amount of mercury and other emissions by 91%.  (Learn more about the proposed rule here).  Won’t you join me in supporting the EPA’s right to limit mercury emissions? Send a comment to the EPA!
