XRF readings:
Lead: 31200 ppm · Cadmium: 1000 ppm · Arsenic: 0 ppm
Verdict: Very high: avoid food contact + High cadmium
This Tiny brass Master-brand lock: 31,200 ppm Lead. For context: 90 ppm Lead (& up) is unsafe for kids. Locks are not toys! tested at 31200 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 1000 ppm, which is also flagged territory.
