The following page, authored by Monte Kline, Ph.D., on the
Pacific Health Center site, cites several believable studies:
http://www.pacifichealthcenter.com/updates/50.asp
"You get more toxic exposure from taking a shower than from
drinking the same water. So reported Science News about a
recent study by a major U.S. university."
"Health and Longevity in August 1994 reported:
The skin, the body's largest organ, can easily absorb
contaminants found in water which pass through it into the
bloodstream. The experts are justbeginning to understand
the potential health hazards from skin absorption of water
contaminants."
"The Nader Report-Troubled Waters on Tap stated:
A professor of water chemistry at the University of
Pittsburgh claims that exposure to vaporized chemicals in
your shower and bath water is 100 times greater than through
drinking the same water."
"U.S. News & World Report on July 29, 1991 noted:
Studies indicate that chlorine can also be inhaled and
absorbed through the skin during showering and bathing.
Ironically, even the chlorine widely used to disinfect
water produces carcinogenic traces."
"Dr. Lance Wallace of the Environmental Protection Agency stated:
Showering is suspected as the primary cause of elevated levels
of chloroform in nearly every home because of the chlorine in
the water."
"Studies have shown that your body can absorb more chlorine
in a ten minute shower than in drinking eight glasses of the
same water!"
The Pacific Health Center site seems relatively objective,
as it is not selling products based on its recommendations.
Unfortunately, the citations are not linked to the actual
studies. Nonetheless, other pages, though perhaps slanted
with the intent to sell products, such as shower filters,
cite the same sources, among others.
The following page, from YourNutrition.com, cites
14 authoritative sources:
http://www.yournutrition.com/shower-filters.html
"A long, hot shower can be dangerous. The toxic chemicals
are inhaled in high concentrations."
- Bottom Line - August 1987, J Andelman, Ph. D.
"We conclude that skin absorption of contaminants in drinking
water has been underestimated and that ingestion may not
constitute the sole or even primary route of exposure."
- American Journal of Public Health, May, 1984, Vol. 74, No. 5
"Ironically, even the Chlorine widely used to disinfect water
produces Carcinogenic traces. Studies indicate the suspect
chemicals can also be inhaled and absorbed through the skin
during showering and bathing."
- U. S. News & World Report - 29 July 1991, Is your Water Safe
- The Dangerous State of Your Water
"Taking showers is a health risk, according to research
presented last week in a meeting of the American Chemical
Society. Showers - and to a lesser extent baths - lead to
a greater exposure to toxic chemicals contained in water
supplies than does drinking water. The chemicals evaporate
out of the water and are inhaled. They can also spread
through the house and be inhaled by others."
- New Scientist -18 September 1986, Ian Anderson
"Studies have documented the presence in the drinking water
of many potentially toxic volatile organic chemicals
(VOC's)- from chloroform and pesticides to carbon
tetrachloride. Such findings have spurred investigations
into the inhalation hazards these compounds may pose when
released in the air during baths and showers. However,
because shower and tub equipment, as well as other design
features, differed widely in these experiments, air
releases for a single VOC could vary up to 10-fold from
one studied system to another."
- John C. Little, Lawrence Berkeley (California) Laboratory,
Science News, August 15, 1992
"The steamy air of a shower contains significant amounts of
a least two cancer-causing chemicals that evaporate out of
water."
- J Andelman, Professor of Water Chemistry,
University of Pittsburgh
"Almost two decades have passed since known or suspected human
carcinogens were first found in municipal water supplies.
One of them, chloroform, produced by the chlorination process,
exposes millions of Americans. The potential for a major
public health problem is unquestionably there, and yet,
progress has been slow."
- Dr. Peter Isacson, M.D., Professor of Epidemiology, Department
of Preventive Medicine, University of Iowa College of Medicine
"Skin absorption of contaminant has been underestimated and
ingestion may not constitute the sole or even primary route
of exposure."
- American Journal of-Public Health - Dr. Halina Brown
"Showering is suspected as the primary cause of elevated of
chloroform in nearly every home because of the chlorine in
the water. Chloroform [a known carcinogen] levels increase
up to 100 times during a ten-minute shower in residential
water"
- Environmental Protection Agency - Dr. Lance Wallace
"I tell my friends to take quick, cold showers", said
Julian B. Andelman, Professor of Water Chemistry,
University of Pittsburgh, who claimed that the longer
and hotter the shower, the more chemicals build up in
the air.
- San Jose Mercury News, September 11, 1986
"Many investigators have reported on the toxicity and
unexpected high penetration rates of volatile organic
chemicals."
- American Journal of Public Health
"A Professor of Water Chemistry at the University of
Pittsburgh claims that exposure to vaporized chemicals
in the water supplies through showering, bathing, and
inhalation is 100 greater than through drinking the
water."
- The Nader Report, Troubled Waters on Tap - Center
for Study of Responsive Law
"The National Academy of Sciences estimates that 200 to
1000 people die in the United States each year from
cancers caused by ingesting the contaminants in water.
The major health threat posed by these pollutants is
far more likely to be from their inhalation as air
pollutants. The reason that emissions are high is
because water droplets dispersed by the shower head
have a larger surface-to-value ratio than water
streaming into the bath."
- Science News-Vol. 130, Janet Raloff
