Vinyl shower curtains purchased at WalMart, Sears, Target and other stores appear to be quite toxic for their first month of use. These vinyl curtains are manufactured with volatile organic compounds that come out when you open the product, and remain in your house for up to 28 days.
A Canadian research team was responsible for the recommendation to ban the manufacture of these dangerous household products. These PVC (Poly Vinyl Chloride) products were examined in this study entitled "Volatile Vinyl: The New Shower Curtain’s Chemical Smell." Evidently, they contain more than 100 chemicals known to be toxic to humans and they release these toxic chemicals into the air, starting with the moment you bring it home from the store, open the package and take that first great big breath of that chemical smell . . .
The Canadian research team is attempting to persuade the government so that the Canadian Hazardous Products Act can be amended to include these PVC-based vinyl shower curtains as dangerous consumer goods. The scientists have recommended a complete ban.
