All Fish Tested from U.S. Streams Found Contaminated with Mercury

In a new study conducted by the U.S. Geological Survey (USGS), every single fish tested from 291 freshwater streams across the United States was found to be contaminated with mercury.

"This study shows just how widespread mercury pollution has become in our air, watersheds and many of our fish in freshwater streams," said Interior Secretary Ken Salazar.

Mercury is a potent neurotoxin that builds up in the food chain at ever higher concentrations in predators such as large fish and humans. It is especially damaging to the developing nervous systems of fetuses and children, but can have severe effects on adults, as well. The pollutant enters the environment almost wholly as atmospheric emissions from industrial processes, primarily the burning of coal for electricity. It then spreads across the plant and settles back to the surface, eventually concentrating in rivers, lakes and oceans, where it enters the aquatic food chain.

The number one cause of human mercury poisoning in the United States is the consumption of fish and shellfish.

Researchers tested the water, sediment and fish of the 291 streams between 1998 and 2005. Fish tested were mostly larger species near the top of the food chain, such as largemouth bass.

    • Considering the posts I'm looking at here, it would appear that mercury poisoning is much more widespread than I thought.

      Mad as Hatters.

    • Spot on article, we have a serious problem with the toxins produced through electricity production (with coal). People need to wake up and actually start the move towards renewable sources of power.

    • "Here is the only solution: We must tax the fish until they clean up their act! It won't do us any good to go after the corporations that pollute, especially since they now own the government, and I am in the pocket of the corporations. The only way to fix this is to tax all of the fish! Something like a 'mercury tax' should do the trick and keep them fish in line." - Al Gorefish

    • What you must understand is
      1) The FDAs recommended mercury levels have a 1000% built in safety cushion. Which means that they exaggerate the real numbers so you couldnt possibly reach them. You can eat 5 pounds of fish every day for your lifetime and never reach the TRUE uncushioned levels and have any ill effects.
      2) It is a fallacy that mercury stays in the body

      I'm fairly sure that mercury will leave the body eventually but this "You can eat 5 pounds of fish every day for your lifetime and never reach the TRUE uncushioned levels and have any ill effects." isn't true, unless you're also a robot. And by the way, that website is clearly funded by the food industry if you didn't happen to notice it's extremely biased point of view. They're downplaying everything because they want you to buy more fish (obviously).

      --------" What you must understand is ........."--------

      What YOU must understand is that mercury(and other heavy metals such as lead) is concentrated in brain and nerve cells. All other cells in the body regenerate, nerve and brain cells do not. What you got is all you got----if you lose 'em, you won't ever get them back.

      Any mercury is hazardous, even very small doses. Once there is enough to see symptoms, that's it, even if any further deterioration is avoided by removing exposure---the symptoms are permanent and can never be reversed.

    • ... because these developmental neurotoxins make us dumber, our economy is losing 8.7 billion annually on lost productivity. The Surgeon General says woman wanting to get pregnant shouldn't eat canned tuna up to a year before CONCEPTION. Scary shit, people.

    • I knew there was a reason I threw my catch back.... How much Mercury were they contaminated with? And what is the normal amount of Mercury found in the seafood in nonpoluted water?
      So if you grew up in an old house with lead paint and ate a lot of Mercurized seafood your chances of being neurologically challenged are high? That sux.

      Mercury concentrates in nuerologic tissues---primarily the brain and spinal cord. The most evident early symptoms are dementia and tremors. Nerve damage is permanent and irreversible.

      It was first described in the 1840s among hat makers in London, England, who were exposed to mercury compounds used to treat animal fur the felt was made from. Hence, the term, Mad as a Hatter. Which later found its way into the Lewis Carroll novel, "Alice In Wonderland" in the Mad Hatter character.

      Thanks for the reference, especially the Mad Hatter reference. Makes perfect sense! Now you just wash the wool in the washer with soap and very hot water to felt it.
      Makes you wonder how people figured out what chemicals did what to get certain results. Most were probably serendipitous, and the person just took off on it as a way to sell the results. One multimillionaire found out how to make coke from the waste he was hauling down the river near Connelsville, PA. He pulled his barge over to eat with some other workers on the side of the river. The barge sitting there at the rivers edge caught on fire and they all jumped up to douse it wth river water and Lo and Behold coke was the result! He became rich in coke production used in the manufacturing of iron and steel! Every where there's a coal mine here in SW PA there are remnants of brick coke ovens. They were a great place to live in for homeless people during the great depression.
      I know we have a big glass manufacturing area here in SW PA, and there are different problems with jobs related to it. People that painted lamps and dishes had different reactions to the turpentine and other chemicals used. The gold used to decorate caused systemic problems especially when doing details the workers would constantly use their lips to get a point on the brush to do fine gold work.... poisonous!

    • Yeah, this is why I stopped eating fish about 2 months ago. At that point I already wasn't eating any land dwelling animal. So now, except for the milk I drink, I'm basically vegan. Although I am looking to replace cows milk with some other type of non-animal protein source that isn't non-fermented soy. Suggestions?

      Almond milk. Yes, I know it sounds crazy but there is such a thing. Check Trader Joes or Whole Foods if you have one near you. I also think there is rice milk.

      I'm also off fish. Not just for the mercury but from pcb's and plastic. I was reading an article a few days ago (can't find the link this second) but it was talking about the Pacific and Atlantic plastic garbage gyres. According to some research done last year, fish in those areas are ingesting small pieces of plastic. We don't eat those fish. But we do eat the fish that eat them.

      I got off meat and chicken too because of all the chemicals, etc in their feed.

      It sucks what we've done to our food system. I am an omnivore gone mostly vegan to avoid all the chemicals that are making people sick. The only thing I can't totally give up are eggs. The rest of it, knowing what's in it now, just turns me off.

      Ehicalvegan, I'm on my way but the onyl thing I can't give up are eggs. The rest of it, learning what's in it, I see no reason I'd want to eat it. Everyone I know who is vegan looks 10 years younger than their age and they just don't get sick.

      Actually, that tends to be true. No one who meets me comes close to guessing my true age, which is kind of fun. I'm not vain, but it is fun when people react.

      No apologies necessary about the eggs. I try my damndest not to judge people on what they eat but, if they ASK me about being a vegan, I'm pleased to explain my reasons. My best friend can't sit at the same table with non-vegans. I'm okay about it, as long as the meat-eaters don't pressure me with questions or condemnation (as is usually the case).

      that "some" will encounter? There is no single consensus on what might happen when the mythical bearded white man from space comes back from the other dimension.

      Read up about the people who live around Lake Victoria in Tanzania. THAT is hell.
