Patch testing results in Table I show that West Virginia has comparable rates of tested contact dermatitis allergens to the rest of the United States with exceptions of higher amounts of mercapto mix and potassium dichromate. Mercapto mix is a common rubber additive (9), and potassium dichromate is used in cement-based construction and chemical processing.
The allergens used included the following 20 allergens: control (petrolatum), potassium dichromate 0.5%; neomycin sulphate 20%; cobalt chloride 1%; benzocaine 5%; formaldehyde 1%; paraphenylenediamine base 0.1%; parabens 15%; nickel sulphate 5%; colophony 20%; mercaptobenzothiazole 2%; nitrofurazone 1%; epoxy resin 1%; fragrance mix 8%; chlorocresol 1%; wool alcohol 30%; balsam of Peru 25%; thiuram mix 1%; black rubber mix 0.6%; Parthenium.
Among thesepollutants chromate (CrO4 2-), dichromate (Cr2O7 2-),phosphate (PO4), nitrite (NO2 ) and selenate (SeO4) are the most common ones [21].
The list of potential allergens to consider includes metal (especially nickel, cobalt, and potassium dichromate), fragrances such as formaldehyde and balsam of Peru, and preservatives, as well as topical emollients, corticosteroids, antibiotics, and antiseptics.
