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.)

As always, thank you for reading and for sharing my posts.
Please let me know if you have any questions.
Could we have a model name and number from the mfr? So as not to so easily confuse the good from the bad?
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.
You said the silver Kwikset were ok, but was it the chrome or the satin nickel finish or both?
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.

Trying to figure the same thing out, Pam! Which one did you end up going with based on your judgement?
