Kwikset door handle: No Lead! But 494 ppm Mercury (Hg).

| | | | | | | |


When tested with an XRF instrument the Kwikset door handle pictured here had the following readings:

  • Lead (Pb): non-detect
  • Cadmium (Cd): non-detect
  • Mercury (Hg): 494 +/- 185 ppm
  • Barium (Ba): non-detect
  • Chromium (Cr): non-detect
  • Antimony (Sb): non-dtect
  • Selenium (Se): non-detect
  • Zinc (zn): 168,600 +/- 1,800 ppm

All testing is done with a freshly calibrated XRF instrument. Test results are science-based and replicable. Testing was done for a minimum of 60 seconds each time (with multiple tests done to confirm the results.)

    1. Hi Mark, I don’t have that information for this piece. I did not see any markings on it anywhere. I can ask the owner if she has any additional information.

      Thank you for commenting.

    1. Hi Pam,

      I don’t have any more information than what is included in the post. The owner of these items did not send me the original packaging so I don’t know the names of the finishes or model numbers. I think these posts should be used as a guide for what is possible in different types of items, not a definitive statement on a specific item since I don’t have more information. I will see if the owner has any more information she can share.

      In general if something says “finish” that means to me it can have a finish over leaded brass, so with the language on packaging I look for things that say “Nickel” or “Stainless” not “Nickel finish” or “stainless finish”. That’s my rule of thumb in the absence of testing every item from every brand.
