Impact/Purpose:
Commercially available portable lead field analyzers can be used for lead quantification of non-regulatory drinking water samples. While there are currently numerous devices on the market with manufacturer-provided information on their lead quantification performance, there are limited third-party studies that have compared these field analyzers to established laboratory methods such as ICP-AES and ICP-MS. This study examined the effects of certain water parameters (temperature, chemical interferences, and particulate lead) on the quantification of lead in water samples by three field analyzer types (electrochemistry, colorimetry and fluorescence).
