what is the Most Dangerous Chemical or poison in the world?
SteamKing said:Dihydrogen oxide is particularly deadly. It's all around us. We breathe it in with every breath, but if we breathe in too much, we die. We need to consume a certain amount of dihydrogen oxide each day to maintain health, but if we go for more than a few days without consuming any, we die. Yet, this chemical is not regulated by any agency in the world.
Borek is right...Borek said:Botulinum toxin is lethal in concentrations 1000 times smaller.
Botulinum is the most acutely lethal toxin known, with an estimated human median lethal dose (LD-50) of 1.3–2.1 ng/kg intravenously or intramuscularly and 10–13 ng/kg when inhaled.
DNA??rootone said:DNA
Emmanuel_Euler said:DNA??
Is DNA Poison??
can you prove that DNA is a poison??Borek said:You have not limited "dangerous" to "poisonous" in your opening post, now you are shifting the post goals.
I told you it is a very poorly defined question, this answer shows why. It is not that difficult to prove why DNA is so dangerous - after all, it is a necessary compound without which we would not evolve, and we ARE dangerous, aren't we?
Emmanuel_Euler said:finally i found it!
i found the video about (what is the most dangerous chemical).Borek said:What have you found? Three people each speaking of a completely different chemical they have DEALT with, not the one they KNOW about. So, which one it is, and why do you assume those mentioned earlier in the thread are not more dangerous?
of courseGreg Bernhardt said:A lot of people die from H2O
DNA based viruses.Emmanuel_Euler said:can you prove that DNA is a poison??
i am listening.
Mark Harder said:A startling example is simple iron! We need iron to live, but iron in usable form is not common enough in nature that we can get enough from scounging nuts and berries and the like. Our bodies have evolved to scarf up iron from our intestines without limit, since placing limits on our iron intake was not necessary during the prehistoric millenia when food, especially the rich protein and iron sources like meat, was scarce. Iron in our intestines is avidly grabbed and held by a protein in the liver for storage there. A nurse I once knew told me a sad story about a pregnant mother taking iron supplements who had a young child to care for as well. The child got into her tonic and swallowed a whole bunch. When the mother found out, she thought little of it - how could iron hurt you? In a matter of days, the child fell ill and when his illness grew alarming the mother sought medical attention. Sadly, so much of his liver was destroyed by then he couldn't be saved. If human tragedy is your measure of danger, iron should be near the top of your list.
Mark Harder said:A chemist recently was working with a sample of the stuff as part of an NMR experiment, I believe.
AlephNumbers said:Hmmm. I feel quite terrible after reading that.

Whether almost 20 years ago counts as "recently" is disputable, but yes, that's a thing some of us remember.
you are right.DNA based virusesiScience said:i'm told hydrazine (C2H4) is quite up there
DNA based viruses.
DrDu said:trichloroanisole ... I suspect it was first developped by algerian extremists to drive out the French colonists. Alone the thought of the desaster a muslim extremist might cause in a region like Bordeaux with only a few drops makes me shudder.
Borek said:Technically neither.
The most dangerous chemical is subjective and can vary depending on various factors such as its intended use, concentration, and exposure. However, some of the most commonly known dangerous chemicals include hydrogen cyanide, sulfuric acid, and chlorine gas.
A chemical can be considered dangerous if it has the potential to cause harm to humans, animals, or the environment. This can include properties such as being toxic, corrosive, flammable, or reactive.
Chemicals are classified as dangerous based on their properties and potential hazards. This classification is determined by regulatory agencies such as the Environmental Protection Agency (EPA) and the Occupational Safety and Health Administration (OSHA).
The health effects of exposure to dangerous chemicals can vary depending on the chemical and the level of exposure. Some common health effects include skin irritation, respiratory problems, organ damage, and even death.
To protect ourselves from dangerous chemicals, it is important to follow safety protocols and precautions when handling them. This can include wearing personal protective equipment, using proper ventilation, and following proper storage and disposal procedures.
