XRF readings:
Lead: 103600 ppm · Cadmium: 7314 ppm · Arsenic: 0 ppm
Verdict: Extreme: do not use + High cadmium
This Garfield “Use Your Friends Wisely” McDonald’s mug: 103,600 ppm Lead (causes brain damage) + 7,314 ppm Cadmium (causes cancer) tested at 103600 ppm lead, heavily contaminated. If any of the lead is on the painted surface, decoration, or worn area, expect bioavailable exposure with food contact, mouthing, or abrasion. Cadmium reads 7314 ppm, which is also flagged territory.
