Whether it's inhaled, swallowed, or, more rarely, absorbed through the skin (just by touching a product that contains lead), lead can act as a poison. Exposure to high lead levels in a short period of time is called acute toxicity. Exposure to small amounts of lead over a long period of time is called chronic toxicity.

They are crucial for the mechanic, visual artist, architect, and surgeon. Yet traditional schooling does relatively little to foster the development of these abilities, and that's troubling.
Spatial describes how objects fit together in space, either among the planets or down here on earth. There's a spatial relationship between Mars and Venus, as well as between the rose bushes in the backyard. Spatial has to do with the distance between things, so mathematicians and computer scientists love using the word. They measured the spatial relations of ping-pong balls in the gravity-free room.. It can also refer to how people perceive the objects in front of them.
