There have been concerns about the recycling of painted concrete due to possible lead content.

Paint with significant lead content is still used in industry and by the military.

Laboratory tests can determine if tap water has a high lead content.

"When you get the brass ring, why ask about the lead content?"

Paint flakes fall in a light snow, and no one is sure of the lead content.

Nervous about the lead content of city water, they found a home outside Warsaw that had its own well.

The lead content of paint has been limited nationally since 1978.

This may in part have been due to the high lead content of the local spring sources.

Still, there must be a high lead content in the soil.

They were required to reduce the lead content to 1.5% after April 2001.
