Abstract
To determine compliance of paint with health regulations, a simple and inexpensive procedure was devised for rapidly identifying paint scrapings containing in excess of 1% lead. A 25-mg sample weighed on a unique field balance is digested with HNO3. Water is added and the lead is precipitated as the iodide. Conditions are empirically adjusted so that more than 1% of lead is required for a positive test.
