Accuracy of a commercial lead test kit

Abstract

  Up until 1960s, lead was widely used for constructing plumbing systems, and a residual amount of lead is still detected within water systems today. Due to the wide availability, low-cost, and ability to produce an instant result, commercial lead test kits have been known for their convenience. However, considering that small lead exposures can pose serious health concerns to those who are vulnerable, inaccurate results may cause a potential health hazard. This study investigated the accuracy of a commercial lead test kit called “10-in-1 Drinking Water Test Kit” by Baldwin Meadows and compare its findings to instrumental analysis.
