Mercury consumption.

Postby VeenaandNivyah » Sun Oct 23, 2005 2:32 pm

Hi all, :D :D :D
How does mercury consumption(even by mistake) affect the food chain? :?: In the Minamata Tragedy in Japan that's what happened right? The consumers were affected in many ways? Why did this happen in the body?
Thanx all, :D :)

The phenomenon you are looking for is bioaccumulation.

Oh man, consumption of heavy metals by lower animals in the food chain is a big deal. Yeah, not a very good thing at all.

i learned it as biomagnification but perhaps it's the same.

Consuming heavy metal actually doesn't have any effect on us [human], but our body is tryin; to decompose them by using anti-xenobiotic immune system which process makes these heavy metals become dangerous for us..

hei.. how about tetanus.(u know kinda of dissease that caused by anaerob respiration. and has the relationship to the metal. u know when we get hurt by metal, e.g. FeO2 we may get a high risk on tetanus-caused by Clostridium tetani)
mm.. how bout the kind of metal we consumed makes our regulation became ....(make us dizy,+++) hei our sitoplasm (may be our intersitium) buffer properties are corrupted so that it wont work properly.
hei.. i think heavy metal is dangereous....

ho... :shock:

@mithril
Bioaccumulation:
increase in concentration of a pollutant from the environment to the first organism in a food chain
Biomagnification:
increase in concentration of a pollutant from one link in a food chain to another

I guess biological amplification is the same as biomagnification then?

Maybe my memory is failing, but I seem to remember an ecology class that we used that term.

-First, Tetanus caused by C.tetani
-Second, There's no such "FeO2" because Fe or Iron only have 2 oxydation number which are 2 and 3. So, Fe only can form FeO and Fe2O3.
-Third, that's because of the bacteria's pathogenesis..not metal disruptment.
-Fourth, as I said before, metals in our body usually as Fe and Cu which are classified into light metal (mass number: Fe=52 and Cu=63.5) while Mercury is the heavy one (mass number: Hg=200.59)..so, degradating it will generate highly free radical ions that can attck or system...

so... at last it makes us keep in danger..right?
... radioactive metal is heavy to.. radioactive has a high risk of disaster to us...
