Toxic Inorganic Compounds
Transcript of Toxic Inorganic Compounds
The degree of strength of a poison
The state or quality of being poisonous
Liquid at room temperature, although very volatile (boils at 26C).
Rumored to have been used in war, although not confirmed
Reported to have been used by Iraq in the war against Iran and the Kurds in northern Iraq in the '80s.
During WW2, a form of HCN (Zyklon B) was used by Nazis in the gas chambers during Holocaust.
Found in some foods such as cassava.
Has appearance similar to grains of sugar.
Smells of almonds.
Used by Nazis
The halogens are the elements found in group 17.
All three states of matter can be found among the halogens at standard conditions.
All toxic in their own right!
Become less toxic as they get heavier!
Many elements and compounds are dangerous!
Stay away from radioactive elements and compounds!
Usually found bonded to other compounds or elements.
Common examples: Sodium cyanide (NaCN), hydrogren cyanide (HCN) and potassium cyanide (KCN).
Has high affinity for sulfur and certain metallic complexes, especially iron(III)!
Can cause death in minutes!!!
Hydrofluoric acid = toxic!!!
Can penetrate skin and cause painful burns!
F2 can be lethal in amounts of 5-10 grams.
Highly toxic as well, but less than fluorine!
Breathing it in at:
3 ppm causes rapid toxic reaction
50 ppm highly dangerous
500 ppm for several minutes is lethal!
Once known as "bertholite" and was first used as weapon by Germany in WW1.
Reacts with mucous membranes to form HCl.
Pure bromine is somewhat toxic, but less than both chlorine and fluorine.
100 mg = lethal
Least toxic of the halogens!
Can irritate the lungs and eyes!
When taken orally, only 3 grams can be lethal!
Arsenic & Arsine
Can result in gastrointestinal effects and also cause central and peripheral nervous system disorders.
Doses of ~600 micrograms/kg body weight/day or higher has resulted in death.
Oral exposure at elevated levels has resulted in many issues such as anemia, gastrointestinal effects, skin lesions, and kidney or liver damage, to name a few.
Has been linked to cancer!
One of the simplest known compounds of arsenic and is found naturally in the gas phase.
Acute inhalation exposure has been known to lead to death!
Main difference between arsenic compounds and arsine is the main route of exposure.
Alpha particles and decay
Beta particles and decay
Gamma particles and decay
"There is no safe dose of radiation." - Dr. Ian Fairlie
It's not like all the other toxins that have been talked about!
Radiation can actually destroy cells!
Different radioactive elements and compounds can do different damages to the body.
