Heavy metals (in English: Heavy metal): not defined specifically, but in general it has elements of physical properties such as transition metals, and some semi-metals, lanthanides, actinides.
In multiple attempts to find out the specific definition of some heavy metals depends on the density, or the atomic number, atomic weight or, or some chemical properties and the level of toxicity.
And in a technical report of the [1] IUPAC, said heavy metals term "misleading term" because of the discrepancy in tariffs, and the lack of "coherent scientific basis" depends upon terminology, as some heavy metals can be lighter or heavier than carbon.
An alternative is a term toxic metals (in English: toxic metal), which is what the different views, because of the lack of precise definition.
Last common definition is based on the weight of the metal (and here comes the heavy metal name), where it applies to all metals that weigh more than 5000 kg / m³; such as lead, zinc and copper.
Heavy metals are naturally present in the ecosystem, with significant differences in focus. An increase in the proportions but recently due to industrial sources and industrial effluents, and leaching of metal ions from the soil into lakes, rivers and acid rain, pollution incident of waste from fuel in particular.
Heavy metals organisms relationship
Organisms need different amounts of "heavy metal", such as iron, cobalt, copper, manganese, molybdenum, zinc and selenium, as these metals consumption is necessary and important to maintain the metabolism (metabolism) the body of an organism. But the consumption of large amounts of them (high concentrations) be harmful and even toxic and result in so-called heavy metal poisoning.
Minerals make up 45 percentage of the human body weight, and are mostly concentrated in the skeleton. Dangerous heavy metals from bio-accumulation in the human body and come faster through the degeneration of metabolism (metabolism) or remove it.
An example of environmental contamination by heavy metals
In 1932, the sewage in Japan water, which contained high levels of mercury in the port "Menemata- Minimata", which resulted in the bio-accumulation of mercury in marine organisms, and the emergence of cases of poisoning in 1952 and known as the "spent Showing Menemata - Minimata syndrome ".
The treatment of heavy metal poisoning
Tests:
The first step in the treatment of poisoning resulting from heavy metals is to identify the source of poisoning (to identify the type of metal that caused the poisoning).
Do laboratory tests, the easiest way is the hair analysis although it is a controversial test.
There are additional tests that are used chelating drugs (Chelating drugs) with a compilation of Paul 24 hours to determine the proportion of heavy metals.
Other important tests urinalysis, complete blood image, wipe the blood hair and urine.
Treatment:
Alastkhalaba treatment (Chelation therapy): It is universally accepted way to rid the body from the effects of toxins and heavy metals. And the interpretation of this term is as follows. Derived due to an ancient Greek word meaning "clawed", and is used in this type of therapeutic factors combine with toxic heavy metals such as mercury, lead or arsenic to equal impact and allow to get out of the body without interaction with other chemicals.
The term chelating release him scientists gives meaning to the abduction of the metal of the body in order to facilitate its absorption or ejected as in the case of toxic metals.
Intravenous therapy (Intravenous therapy), vitamin C, and (Glutathione).
Coriander to treat Althagalh- diet rich in fiber: fiber in the form of "generation" to prevent the entry of heavy metals into the stomach of metal poisoning.
The coriander defend the brain and central nervous system effect of heavy metals.
Melatonin.
A compound of magnesium and acid apples (Magnesium malate): Ghaderaly to pull the aluminum from the body.
Selenium: combine with other heavy metals such as cadmium and mercury to reduce the toxicity.
Zinc: prevents permeation cadmium and lead to different tissues of the body .. It is well known that zinc copper red enemy.
Food: Garlic Alpha fatty acid (Alpha lipoic acid), organic form of sulfur content in the food of the dairy, grain, meat, vegetables, fruit and products (Methylsulfonylmethane / MSM) help protect the human body from heavy metals in general, and in particular in the output from mercury poisoning .
