Lead poisoning or (plumbic poisoning) as it is known is by the ingestion of either lead (which is decayed uranium) or it's compounds. these can be found in lead acid batteries, paints (red lead) paint being a good example or by toxic fumes from smelting or a classic poison is called "sugar of lead" which is lead acetate this both resembling sugar and tasting like sugar too. the ingestion of plumbic (lead) compounds leads to plumboporphyria which sends the person insane.
It's found in quite a few compounds.
Anytime you think you smell fumes in a vehicle for a length of time the exhaust system needs to be checked. Carbon monoxide could be leaking into the passenger compartment and can lead to sickness or death.
Actually there are lots of elements which are commonly found only in compounds rather than in their pure elemental form. Sodium, magnesium, calcium, hydrogen come immediately to mind, but there are lots more.

Yes, severe. Phosphine gas, lead fumes... Toxic stuff. Google is your friend.
Lead is the only element. all others are compounds.

The substance in smoking fumes that creates cavities is nicotine. Nicotine does not only lead to cavities, but it also can lead to mouth cancer as well.
Now lead compounds are not used at home because they are toxic.
Lead is an element and is natural, but is not often found in its pure state. It is usually found in an ore that has a lead compound and a mixture of other compounds of other metals. It is then refined to produce more pure lead metal.
