Composition of red mud

After the disaster, the alumina (MAL), the following was published in the composition of red mud:
pH: 13
Content is toxic?
Fe2O3 (iron (III) oxide) (iron oxide, hematite, rust), 40-45% of the practical life, it does not cause poisoning. But if you yourself filled with all kinds of filling materials magnificent charlatan dietary supplement, you can get from iron poisoning., 6 years old children are more sensitive to that sort of thing. But it is not an easy thing to do, because the iron is poorly absorbed, much, much more happens is that someone of iron deficiency - but it is not recommended, of course, rust in the form of iron intake.
Al2O3 (aluminum oxide, alumina, corundum, ruby, sapphire), 10-15% do not. Although the aluminum itself more and more lately accused of everything. Responsible for making such a gyorsn?veked?s and the cause of Alzheimer's disease. Neurotoxicant and carcinogen think.
Aluminium salts are mainly used in preparations inhibit sweating. In addition, you better aluminum containers (especially sour things) do not cook, do not use an aluminum spoon and fork.
SiO2 (silicon oxide, quartz, sand) 0 -15% Non-
CaO (calcium oxide, limestone) 6-10%
No, but an alkaline caustic. Avoid contact with eyes.
Strong contact with water, heat and hydrogen development during the same effect of calcium hydroxide, formed by far.
TiO2 (titanium oxide) 4 to 5% of our knowledge, the human body in the state of science has no effect. But the BBC's claims about the website to be a carcinogen. This is very interesting because bleaching agent soap, toothpaste, sunscreen, paints, and even food that is loaded onto the otherwise wasted precious metal oxidj?t. Foods are also known as E171.
If that's true, then you will not receive the v?r?siszapt?l the titanium oxide r?kunkat.
Na2O (sodium oxide) or NaOH (sodium hydroxide, caustic soda, l?gkő) 5-6% No, but both are very strongly alkaline caustic. In contact with water, NaOH Na2O-da occurs. Both animal and plant tissues to a large extent destroy. Contact with water, a strong exothermic effect, which is too alkaline milling, plus burn injury. If the crystal is a solid NaOH for a short time pick up, if the skin is intact, at first just to see that it will be slippery. This feeling is caused by the epidermis of our skin that has already begun to dissolve. If we would do such a thing, your hand does not fogdossunk with anything, and especially do not touch your eyes! But as soon as possible with plenty of water to wash it off!. To me, webmaster of this website once a minor accident had the opportunity to taste a few drops of NaOH solution. Fortunately, not swallowed. The solution was 1 M, which means that in case of NaOH to 1 liter of water 40 g NaOH was dissolved. It's not a lot like eating a heaping spoonful. I knew what to do: I ran the water supply at the moment, one is already 5 seconds under running water in my mouth. Nevertheless, some 2 weeks after the incident strongly hurt my tongue! This case also warns of NaOH is not a toy!
But not only the water but the air sz?ndioxidj?val would like to merge, bypassing the soil, sziks?v? (Na2CO3, soda) has rearranged the cause of soil salinity / alkalinity.
Not much later, the Hungarian Academy of Sciences, also published an analysis, which can be found here:

Then the environmental organization Greenpeace also performed blood chemistry tests, and have been calculated, accusing the MTA of the total, with intent to substantially lower values have been the reality.
The data from Greenpeace:
arsenic: 110 mg / kg of mercury: 1.3 mg / kg, Cr: 660 mg / kg
The effects of arsenic poisoning can cause serious, in some places but unfortunately the water is included, but such water, if the arsenic content reaches a specified value, you should not drink. Very, very small amounts (0.012 to 0.025 mg / day) is also in the human body needs it, but above this is already dominated by a toxic effect, mainly in the digestive tract, bone marrow and nervous system damage. 50-50 mg / day over the toxic arz?nterhel?s of 100-300 mg / day range becomes deadly szoktat?ssal This volume increase is anyone accustomed to a daily 0.5 g of arsenic can also be enjoyed without damaging their health from the legcsek?lyebben.

The mercury is already very dangerous poison, so that just 1 gram, 1 million liters of water can be ihatatlann?! Therefore, if a mercury thermometer ?sszet?rn?nk, sprinkle sulfur powder available in pharmacies or chemical store, so now it does not evaporate easily and ?sszetakar?that? mercuric sulfide is produced by a gathering to give off a hazardous waste collection!
Today also are increasingly replacing incandescent bulbs for compact fluorescent lamps (energy-saving bulbs is incorrect names). These ?vegj?nek belsőfel?let?n in white powder, also mercury compounds. Therefore, they are also not just throw in the bin and do not break up, but put into receptacles placed in department stores!
The mercury on Wikipedia:
http://hu.wikipedia.org/wiki/Higany
No specific toxic effects of chromium, but if ingested, it can be as heavy metal precipitates and the szervezetfeh?rj?it can cause problems. In practice, the major impact of causing allergies, a population equal to about 2-4% of chromium exposure causes an allergic reaction.
The minimum amounts of chromium in the body, nyomelemk?nt need.
However, larger quantities of highly toxic chromium salts. For example, chromium oxide, chromium trioxide, CrO3 - already has 0.6 grams can be fatal. Mainly attacks the kidneys, but also harmful to other organs. Acting carcinogens and mutagens.

The MTA and the huge difference between the results of Greenpeace Greenpeace has explained to the Greenpeace spilled sludge sample, while the MTA uses the model's pre-party: hence it is concluded that the party has spilled sludge samples and the composition must be different, even , because the sludge disposed of hazardous waste could be concealed in other post-iszapk?z?. such as galvanic, which unfortunately has been the alm?sf?zitői timf?ldgy?rn?l example.
The National Disaster Management (OKF), the Hungarian Academy of Sciences (MTA) and the National Public measurements, as authentic and scientific information resources - responded to the OKF Friday afternoon, MTI has been said a Greenpeace press conference that day, the environmental organization with reference to two independent testing lab said that the toxic red mud kolont?ri officially ?ll?tottn?l.
Greenpeace is now a more detailed test results for Monday, scheduled for the 11 promised to be ready by then more anal?zis?kből.
