Can't believe Climate Change? How about mercury in your child's tuna sandwich?

Maybe we can agree that we need to stop burning coal to reduce the amount of mercury that finds its way into tuna and many other species of fish, both in ocean and lakes. If we switch to clean energy, like wind, solar, and geothermal, we clean the air AND reduce the amount of carbon dioxide dumped into the air.... and clean up your tuna sandwich.

The article below will explain that "U.S. coal-fired power plants pump more than 48 tons of mercury into the air each year....about 3 percent of the global total".

Got kids? "One thing that isn't in question, though, is that developing fetuses are particularly sensitive to the toxic effects of methylmercury. Two out of three large-scale studies have found that children born with it in their system have trouble with coordination, concentration, language, and memory—and continue to have the same deficits many years later".

From same article: Nancy Lanphear is a behavioral developmental pediatrician who works at a clinic in Vancouver for children with disabilities like autism or attention-deficit/hyperactivity disorder. Several years ago, a mother came into her clinic with a four-and-a-half-year-old girl who had cerebral palsy as well as speech and motor delays. But what attracted Lanphear's attention was that the child was drooling. I'm looking at this four-year-old and saying, 'This is mercury,'" Lanphear recalls, hypersalivation being a classic sign of mercury poisoning. The child's chart showed that a heavy metals screening at age two had found high mercury levels in both mother and child, as well as in the child's grandfather. The mother recalled being encouraged by her physician to eat fish during her pregnancy; she ate tuna or other seafood two to four times a week, sure that she was helping her baby's development.

Thanks for your interest. Let's make a difference...for the kids.

    Deniers tend to try and deny this as it pokes a whole in one of their AGW argument that we can affect the globe, on a number of levels pollution is global and can hardly be denied we all see it in river ways or the beach, if those dullards got of their backsides and looked beyond their childish forums they would see for themselves. but instead the come here and do string answers using multiple accounts (pretty easy to see who I mean) one after the other.

    Mercury is a known problem and medical groups around the world advise that people limit their intake of fish (especially long lived fish, like Shark) for this very reason, in the denier mindset I'm sure they will invent yet another conspiracy to try and explain why doctors are doing this when the reality is doctors are doing this because the levels of mercury in fish are much higher than they used to be.

    Peter z's comment is true, we at least it is if you feed your children CF lamps.

    Tuna is often the fish that gets the headlines because of bio accumulation, they live longer and are higher on the food chain, so they get more into their system. I've known 3 people who have been diagnosed with mercury toxicity. They all has one thing in common, a sushi habit. A few ounces of Ahi tuna can put you over the considered safe limit for mercury exposure.

    Mercury is released when coal is burned, that is a fairly well known fact, that is what all the "Clean Coal" talk is about, they believe if they pump the emissions from the smoke stack into the ground it will reduce the mercury contamination. Many coal plants have dead zones surrounding them, nothing will grow. It gets to the ocean several ways, it's air born, it lands on the ground and gets washed into streams, which eventually lead to the ocean as well, that's the way watersheds work. The US isn't the top contributor at least not directly. China has massively expanded it's coal industry and they have far lower environmental emissions controls than we do. But the reality is, most of the energy is being used to make stuff for our retail markets and to house the people that have moved from the farms to the city to make our stuff.

    We all have choices, I chose to get solar panels and get the balance of my energy from our cities renewable energy plan.

    There is mercury in the bread for the sandwich too. I contracted the SRC to do elemental analysis of wheat samples under one of my research grants. My research pertained to quantifying the emissions from wheat-based biofuel. Incidentally, there is a difference in elemental composition between healthy and diseased plants. I will share the results with any academic botanist with an interest in wheat fungal resistance mechanisms.

    I notice that the left always takes a sudden interest in children if they can use them to further their political agenda. They typically hold children hostage in budget battles. Obama claims that children won't be educated if we don't pass his idiotic jobs bill that is nothing more than the last stimulus, a left-wing slush fund. When they can't argue things on their merits, they attempt to scare people with their children.

    One of my wife's students is a 2nd grade active boy. They just diagnosed him with attention deficit disorder and I think he just started taking Ritalin (spelling?). Personally I am appalled and I doubt that lead or mercury has anything to do with it. I think they all too often are too eager to diagnose anything and everything and give pills and try to make everyone the same when they aren't.

    There are some wackos out there that accuse vaccines of causing autism because of the mercury used as preservatives. Scientologists seem to believe this. This seems to be along those lines.

    I agree that you should just be careful about eating too much fish, at least the top of the chain predators like tuna. Your contention that our mercury from our coal is causing this is unsubstantiated IMO.

    If you are worried about it, just don't give your kid canned tuna. Don't ask the world to shut down their power plants. And how do we know that the mercury found in fish came from the power plants? We don't.

    Children are in far more danger of being exposed to too much mercury from Compact flourescent bulbs than they are from tuna.

    Are fetuses only susceptible from the kind that comes from tuna?
