hasanmoukalled Posted April 19, 2013 Share Posted April 19, 2013 Today in the laboratory in my school, I wanted to make a small Ammonium Dichromate volcano. The lab teacher got a very small amount of the substance and then heated it up to see the reaction. She said it is a carcinogen substance, so I got worried about my health. Must I worry? I didn't get in touch with the substance but maybe I inhaled a very small amount of gas while it was burning, and I don't remember I got in touch with the green substance. Can you help me please. The best answer will be chosen. Thanks! Link to comment Share on other sites More sharing options...
elementcollector1 Posted April 19, 2013 Share Posted April 19, 2013 Ha! No. Short-term, low-dosage exposure isn't a problem. And what do you mean by 'best answer'? Link to comment Share on other sites More sharing options...
Enthalpy Posted April 19, 2013 Share Posted April 19, 2013 MSDS confirm it is a carcinogen, as is almost every non-natural substance. But you have to distinguish the amounts, exposure duration... Which the MSDS don't. Just as one example, you might read the MSDS for ethanol - you know, the poison that so many humans ingest knowingly and willingly: http://www.sciencelab.com/msds.php?msdsId=9927073 http://www.nafaa.org/ethanol.pdf proven carcinogen, proven mutagen, proven teratogen, lethal dose 7g/kg, and so on.

Actually first I asked Yahoo Answers and I got it wont effect, but I wanted to make sure more so I copy-paste it here for more information about it. Thanks I want to know all the carcinogen substances and toxic ones, can you help with a website? Thanks!! MSDS confirm it is a carcinogen, as is almost every non-natural substance.

So I must not worry, right? It was my first exposure for this substance. The amount was too little, barely the size of the upper part of the pointer finger (I mean if you open your hand and turn it around, the upper part of the pointer finger, if you want the third hinge). Thanks!! Link to comment Share on other sites More sharing options...
John Cuthber Posted April 20, 2013 Share Posted April 20, 2013 Lots of us have done this demonstration with much larger amounts of ammonium dichromate, and possibly with less care.. We are still here. Stop worrying Link to comment Share on other sites More sharing options...

Thanks!! Good luck getting *every* carcinogen - there must be millions! And that's what we know: There's probably billions more that we don't.

ajkoer Posted April 23, 2013 Share Posted April 23, 2013 (edited) To quote from a reputable authority: "In the past, quite a few great chemists were severely poisoned, not by HNO3, H2SO4 or HCl, but by HF. Some to name: Davies, Moissan (first person who made elemental fluorine). Apparently, some of these great chemists have suffered great pains from fluoride poisoning." On dimethyl mercury, Wikipedia has an article about a chemist who died from just a few drops on her hand a couple of months after exposure. Wow! Apparently, Karen Wetterhahn died a horrific death from dimethyl mercury. Always research chemicals before you use or produce them (start with Wikipedia and MSDSs). Evaluate the risk of your exposure and/or to a third party. If possible, ask the opinion of a professional chemists (they know that some chemicals are just so dangerous they should never be made or employed - seek substitutes).
