The sodium sulfide test for lead. This lead detection 
procedure works by applying drops of a 6-8% sodium sulfide solution to
a dry paint sample (in the form of chip, film, or powder) or to a 
suspected lead contaminated test tube solution sample. If the 
solution turns the paint sample or test tube solution light to dark 
gray or black, that is an indicator of the presence of lead in a 
concentration greater than 0.5%. 105 Code Mass. Regs. § 460.740(2) 
(1995). American Society for Testing and Materials, Standard Practice 
for Use of Qualitative Chemical Spot Test Kits for Detection of Lead 
in Dry Paint Films (1995). Sodium Sulfide reacts with a lead acetate or lead 
nitrate solution to form lead sulfide. Advantages of the sodium sulfide test are 
that it is quick, easy, and relatively cheap. Among disadvantages of 
the test are that  sodium sulfide smells bad (like rotten eggs), 
and that it reacts with several other metals, including iron, nickel, 
cobalt, copper, mercury and molybdenum. The test will, therefore, 
produce false positives.

The sodium sulfide test for lead. This lead detection 
procedure works by applying drops of a 6-8% sodium sulfide solution 
to a suspected lead contaminated test tube solution sample. If the  
test tube solution sample turns light to dark gray or black, that is 
an indicator of the presence of lead in a concentration greater than 
0.5%. Sodium Sulfide reacts with a lead acetate or lead nitrate 
solution to form lead sulfide. The test using sodium sulfide smells 
bad (like rotten eggs) and is limited to recording positive or 
negative results. Because of the need to qualify and quantify our 
preliminary lead ww test results and to produce credible data that 
could be presented to and accepted by the EPA, we chose to partner 
with Dr Wichman of the UHL in Coralville Iowa to gather credible 
toxic lead contamination data.
