Detection of inorganic lead contamination with sodium sulfide.
A qualitative screening method to detect inorganic lead on skin and other surfaces is described. It is based on the development of a brownish to black lead sulfide when sodium sulfide solution reacts with inorganic lead. The procedure can facilitate worker training and assist in reducing excessive exposure to lead of workers and their families.
