These levels are considered safe by all standards. I am comfortable feeding my children off of Ikea dishware. levels in the 90 ppm range or below are considered TRACE lead, meaning a very small amount. This amount is a contaminant in the clay or glaze and is not an additive in the manufacturing process. It is also very unlikely to leach or cause harm to humans at those levels, especially given the Ikea pottery is mass manufactured and high fired. I am much more concerned about so much of the vintage pottery I have tested that often has lead levels in the THOUSANDS of parts per million (or even the tens of thousands.). I have some Ikea pottery in my home and it is lead-free. Newly made Ikea that I have been testing in the past year or so has all either been lead-free or lead-safe (in the 90 ppm range or below.)
