The non-exhaustive list of heavy metals includes antimony (Sb), arsenic (As), barium (Ba), cadmium (Cd), chromium (Cr), lead (Pb), mercury (Hg) and selenium (Se). Children's toys and jewelry may contain high levels of these heavy metals, which put children at special risk through oral, inhalation, skin and hand-mouth contact. They are immersed in the oil in our hands, in the saliva in our mouths and in the acid in our stomachs, and stick to the surface like dust.

What are the hazards of soluble heavy metals?
