"Numerous articles have been written with regard to skin absorption of disinfectants such as chlorine and volatile chemicals. One such article said, "Given the choice of drinking two liters of water contaminated with a volatile chemical at 7 parts per billion or showering for 15 minutes in the same water, the safer choice would be to drink the water." This conservative article said that from two to four times as much of the chemical can enter the body through skin absorption as through the intestines. One researcher says that, during a lifetime, 50 pounds of toxic wastes and pollutants can enter a body from drinking water and at least 450 pounds can enter the body through skin absorption."
