Hello,
A-Skin and Copper :
In the case of copper, the principal route of exposure is
through ingestion, but inhalation of copper dust and fumes
occurs in industrial settings.
Toxicity has resulted from treatment of burns (broken skin barrier)
using topical copper compounds.
Copper has been reported to be absorbed internally from
prostheses, intrauterine devices, hemodialysis units using
copper-containing equipment, and copper azide impregnation
of the skin after an explosion.
Copper causes a greenish coloration of skin, nails, hair
and teeth after being absorbed.
Contact dermatitis (copper itch) due to copper is rare and
its occurrence can be substantiated by careful patch testing.
Eczematous dermatitis and urticaria have been associated
with the use of copper intrauterine devices.
B-Skin and Tin :
Some inorganic tin compounds can cause irritation of the skin or the eyes
because of acid or alkaline reactions produced with water.
Tin tetrachloride, stannous chloride and stannous sulphate are strong acids;
sodium stannate and potassium stannate are strong alkalies.
Tin is also a contact skin sensitizer, this was confirmed by skin tests.
