Medical Forum / General / Dentistry / April 2006Sources of Mercury Exposure in humans
Source Average Human Daily Dose of Mercury Dental Amalgam 3.0 - 17.0 ug/day (hg vapor) Fish and Seafood 2.3 ug/day (methylmercury) Other Food 0.3 ug/day (inorganic hg) Air & Water Negligible traces NOTE: ug=mcg or micrograms (World Health Organization, Environmental Health Criteria 118: Inorganic Mercury, Geneva, 1991.) Is the ONLY reason that fish have lots of mercury in them because of humans? I mean, a million years ago, did they still have some because of just the tendency to accumulate whatever was naturally occuring? Or does mercury basically not occur in nature without humans? > Is the ONLY reason that fish have lots of mercury in them because of > humans?

I'm sure that most of it is due to humans. I know that a lot of Hg is built up in San Fransico Bay for example. They had a lot of gold mining which used Hg and ran off into the bay, probably contaminating the seafood from there. I also heard that some Indian tribes in Canada have gotten people poisoned with Hg from fishing so much, never heard of that happening 100 years ago. This is true. The alchemists finally succeeded. They eventually got silver to get into liquid state and called it quicksilver. Do you think English Springer Spaniels could have accomplished this? Of course not. Its the humans.

Apparently, "mercury is present in rocks, soil, and ores and can be washed into creeks and rivers by storms. Mercury can also become dispersed throughout the atmosphere from forest fires and volcanic activity." >Apparently, "mercury is present in rocks, soil, and ores and can be >washed into creeks and rivers by storms.

By far the largest contributor of mercury into lakes, rivers, oceans ---> fish, is from coal burning power plants. Approximately 40 tons / year, globally.

After all, doesn't all that lava cool down after a few billion years? Doesn't seem to make much sense does it! > How can there still be volcanic activity?

Yep, why doesn't the earth cool off..? 4 billion years is a long time! > > > How can there still be volcanic activity? After all, doesn't all that > > > lava cool down after a few billion years?

You could try and see if there are any geology nightclasses available in your area. > > > > How can there still be volcanic activity?

Someone asked me this recently, I thought about it about 15 seconds and said I couldn't come up with an answer. But it is a good example of how we blindly accept what we are told (Ahem!, the thread topic is amalgam). Turns out the Earths core is RADIOACTIVE! Otherwise how could the heat of the molten core remain insultated for Billions of years? > Turns out the Earths core is RADIOACTIVE!

Yup, it seems longer if its just before Christmas .. -- Joel34 > Source Average Human Daily Dose of Mercury > > Dental Amalgam 3.0 - 17.0 ug/day (hg vapor) > Fish and Seafood 2.3 ug/day (methylmercury) No wonder omega-3 deficiency is so widespread. |
