Children tend to explore their environments using their sense of taste.
This leads to placing objects such as paint chips and dirt into the mouth. At early stages of development, young children are also growing much more rapidly than adults and may be more sensitive to small amounts of lead than adults are.

Lead poisoning can cause adults to be irritable, to have poor muscle coordination, and to suffer nerve damage to the sense organs and muscles.
