How many elements on the periodic table are toxic to humans?
Anonymous

edwardspoonhands:

One hundred and eighteen, i.e. “all of them.” 

Toxic is pretty vaguely defined and but basically it means “some kind of exposure will cause harm.”

Now, obviously not every element will cause harm at every dose. But at a certain dosage…ever element (indeed, every THING) will cause harm. Now, there are widely different ranges of amounts of stuff you can be exposed to before harm occurs (from hundreds of pounds to fractions of micrograms) but the continuum is pretty spread out on the table, so there’s no clear place to draw the line between “safe” and “toxic.”

Paracelsus is generally considered the creator of the science of toxicology and he coined a term chemists still use today “The dose that makes the poison.”

That’s why the government doesn’t regulate whether certain chemicals can be in food or water, it regulates /how much/ can be in food or water.

Important to know.
