Abstract
The Hach Lead-Trak test kit for lead in water was tested in a laboratory evaluation. Considered were: operator bias, precision, accuracy, linear calibration range, and potential drinking water interferences. Interferences tested were realistic levels of: Ca, Mg, Ni, Sb, Mn, Cd, Cu, Zn, Fe(II), Fe(III), Al, NO3(-), Cl(-), F(-), PO4(3-), P2O7(4-), P6O18(-6), and P3O10(5-). Interferences were tested individually in deionized water, using a linear regression slope technique to detect bias. Results of analyses of split spiked samples and actual drinking water samples were compared to GFAAS values. Agreement with GFAAS was generally good from 0 to 50 micrograms Pb/L, but the kit suffered from significant negative interferences from Fe(II), Zn(II), and all polyphosphates. Recoveries of Pb from 6 different tap waters ranged from 81 to 109%. No operator bias was found.
