How To Read Lead Test Results Ceramics

Lead free metals including antimony tin and a lead free solder were tested with the kits to ensure these metals would not give false positive test results for lead table 6.

How to read lead test results ceramics.

The blood lead test is used to screen for exposure to lead. Home lead test kits can tell you if the dishes have leachable lead. I read in some places that only imported ceramics are a problem but u s manufactured tiles do not contain lead. These tests are most useful in detecting high levels of lead.

Both kits gave negative results for these tests and thus they can reliably distinguish lead from antimony and tin which are often used in lead free solders. 3m lead check swabs are the only other lead testing product officially certified by the epa. Like d lead paint test kits they re capable of detecting lead in paint but can also be used on things like tools and children s toys that you might not expect to contain lead. Home test kits use a quick color test.

If your test results were delivered on site at the time of testing xrf testing was most likely used. It may also be ordered to monitor the effectiveness of treatment and to confirm that lead levels are decreasing over time. I also read that lead in ceramics was not covered in the lead ban because in ceramic glazes lead is theoretically contained within the hardened surface of the glaze and not a risk to users. The lead test is used to determine the concentration of lead in the blood at the time the sample was collected.

X ray fluorescence xrf and laboratory testing through the national lead laboratory accreditation program. If the test results came later it was probably laboratory testing.
