Hi all!
Many infants have been found to have excessive mercury in their blood, which can cause mental retardation, and doctors have warned expectant mothers against eating too much fish.
Methylmercury is readily absorbed into the blood after ingestion and distributed to all tissues of the body in four days. In pregnant women, it readily crosses the placenta into the fetal circulation system and is deposited in the fetal brain.
In a study infants over a two-year period , researchers found how much fish mothers consumed directly affected the amount of blood mercury found in their babies.
As many as 24.7% of the infants in the study were found to have cord blood mercury concentrations of over 61 nanomol/liter, the upper allowable limit. Three percent had blood mercury concentrations of over 100 nanomol/L.
"Eating too much fish by the mother during pregnancy is the major factor in elevating the blood mercury level of the fetus,The major source of human mercury intake is dietary methylmercury present primarily in fish and other seafood."
In adults, mercury poisoning causes personality changes, nervousness, irritability, fatigue, insomnia, headache, loss of memory, hearing and vision and even renal failure.
In babies, it may lead to stillbirth, cerebral palsy, mental retardation, speech delay, poor control of chewing, salivation and swallowing.
So in conclusion however, fish commonly caught and heavily consumed were not found to have excessive levels of mercury but having much more fish will develop problem.
hope everyone will read.

Hey Sis,

Hi Gurl_Interrupted ! Thanks for your prumpt response.
"In a study of infants, over a two-year period " typing mistake.Yah you are absolutely right about the infant.Two yrs here are the observation period that researchers obeserved.
thanks

No doubt that mercury can cause such negative effect. I think that information is very helpful, specially for expectant families.
One question, missgrg, did the study categorized the consumed fish by territory? It is possible that the fish consumed under the study, might be coming from a
HG-contaminated pond.
Let us know if that doubt is taken care of.

Thanks DWI!
The study was done with in some group of infants in Asia and nothing was contaminated. Not a fish either.
Conclusion of the study was "consuming many fish may damage infant's health".

Thanks Missgrg. Good news for me too, never was a fan of sea food and fishes. Atleast, I won't be another mercury man, since Terminator III is coming soon.

Miss Grg, I may wonder if you could establish the source of your data. Who did this survey? You mentioned that these studies were done in some group Asian. May I ask you to specify which natinality, and which village/city they were from.
As my memory recalls, a village in Japan where the staple food was fish resulted in retardation in the new born babies due to mercury poisoning. This was due to industries dumping untreated industrial waste (including mercury) in the sea. If one consumes fish and other food sources from such area, they it is likely to get mercury posioning. However, fish raised in mercury free environment should not have mercury in their food chain.
Fish is very good source of certain amino acids that are esstential for our bodies. You might want to learn more about mercury poisoning before you quit eating fish.

Ugly bro
If you read above, I raised very similar question. What if the pond under the study was HG-contaminated?
It seems that it wasn't an isolated study, rather generic specimen were chosen. That's what I got from Miss Grg's answer. But may be Miss Grg would clarify it further. You are absolutely right about making it certain before coming to any conclusion.

Ugly Duckling!
thanks for your notification.This study was done in 1057 infants by prof. of chinese university in a small village of china."Eating too much fish by the mother during pregnancy is the major factor in elevating the blood mercury level of the fetus," said Professor Fok Tai-fai at the Chinese University.
And one of chemical pathologist who is also a prof. of same uni. "The major source of human mercury intake is dietary methylmercury present primarily in fish and other seafood."
Curiously, however, fish commonly caught and heavily consumed in that village were not found to have excessive levels of mercury, the researchers said.
"It isn't the case that our fish are particularly bad, it's because we are eating too much fish," Fok said.
As far as i am concerned due to the having much fish by preg. women the problem was arised.That means fish contains murcury though it is not much.
And similarly i have found a information from EPA
"Mercury is a naturally occurring element that is present throughout the environment. Human activity can release some of that mercury into the air, water and soil. In the U.S., coal-fired power plants are the biggest source of mercury emissions to the air".
" Mercury concentrations in air are usually low and of little direct concern. But when mercury enters water, biological processes transform it to a highly toxic form that builds up in fish and animals that eat fish. People are exposed to mercury primarily by eating fish".
I don't know whether you got the answers of your ques. or not!!

Thanks miss grg for the reference.
This clearly indicates that it is an isolated study of just that village.
It seems that mercury, along with the other nutrients passes through the placenta and gets to the fetus. And probably, concentration of mercury increases as the time passes by. As the fetus is developing in the womb, most of the brain development is disrupted by high concentration of mercury.
So, let's not get in the conclusion taht we should avoid eating fish...:)
