the "lead" in pencils is actually graphite. No, it's not dangerous to ingest. No, the lead in pencils is not made from lead it is just called that. It is actually made of Granite which is not a dangerous rock. But if it happens to pucture you or cut you wash your wound with peroxide to kill the germs.
Lead isn't used in pencils. Due to outdated chemistry, the graphite used in pencils was originally thought to be lead. The term lead is still used to refer to the core of pencils even though that isn't actually what it is.
It is a heavy metal and binds to key components in the respiratory chain rather than being digested. It sticks around and build up prevents the production of ATP (adenosine tri phosphate) which is the basic energy source all living things need in order to work.
For practical purpose, lead can be considered stable. 98.6% of the lead ordinarily found in nature is of stable isotopes. 1.4% of lead is 104Pb, which is radioactive, but the half life is 140,000,000,000,000,000 years. There are traces of 210Pb found in nature, and its half life is 22.3 years, but the quantities are not significant. Like all elements, synthetic radioactive isotopes of lead exist.
Yes pure lead is poisonous.
Lead is very poisonous once it gets inside your body, because it disguises itself as an important mineral your body needs to function and grow; as lead disguises itself the body thinks of it as a non harmful substance and allows it to pass into your blood, that's when it's poisonous as it literaly takes up the place of the minerals it disguises itself as.
For growing developing brains and bodies of children lead stops the development. Lead stops the growing and could lead to death. Some symptoms of lead poisoning are stomachaches, cramping, constipation, or diarrhea, vomiting, nausea, persistent unexplained fatigue, headaches, and muscle weakness.
yes it's very deadly to the human body. you could die from lead and should NOT digest lead
Lead is a heavy metal. It shares the same number of valence electrons as carbon and as such is capable of replacing organic carbon in the body.
Yes, it is extremely dangerous to kids.
Yes
A dangerous concentration of lead in soils is considered a concentration greater than 100 mg/kg.
Most tornadoes form in violent thunderstorms called supercells.
A supercell is the kind of thunderstorm most likely to produce a tornado.
There has never been any lead in lead pencils. The graphite deposit that produced the first pencils was mistakenly thought to be lead. Chemists pointed out the error but the name stuck.
Cold fronts are more likely to produce severe thunderstorms and heavy rain that may lead to flooding.
yes lead is dangerous if you sallow it you can get lead poisoning
Lead sulfide is not dangerous.
leave him because they will be involved with dangerous gangs an that could lead to you and your kids being unsafe put yourself and your kids first an get out before its to late this is only an opinon so dont make your desison based on this
dangerous.....
it can lead to problems
Physically the internet is not dangerous - it can lead to dangerous encounters with nutcases for example, but the internet itself is not dangerous.
Oh very dangerous, especially if you live around me.
A dangerous concentration of lead in soils is considered a concentration greater than 100 mg/kg.
You get gold. It is dangerous because manufacturing gold could lead to the collapse of the bullion market.
Ink Poisoning is not more dangerous than lead poisoning though they are equally dangerous. They both occur with long exposure to ink or lead. They are generally not fatal but have damaging effects on the body if not dealt with.
No, there are Kids dumbell weights that are available.
it could kill them
