In the most recent studies, lead was not detectable in most foods and the average dietary intake of lead was about 1 microgram (a microgram is a millionth of a gram) per kilogram of body weight/day. ❋ Unknown (2008)

Now, the point about polonium is of course that we need, as you just said, very tiny amounts, a microgram, which is a millionth of gram, of polonium will do terrible damage to you once inside your body. ❋ Unknown (2006)

Since some xenobiotics are toxic in much smaller quantities than the milligram, smaller fractions of the gram are used, such as microgram (µg). ❋ Unknown (2008)
