Newly installed kitchen counter tile: 368,400 ppm lead.
Tested in 2014.
Tile is not regulated for total lead content (as detectable with an XRF.) This is kitchen tile, that your food sits on every.single.day. My solution is to always use cutting boards and never put utensils or food directly on tiled kitchen counters.
