Dangers of Long Term Chlorine Exposure
Chlorine is a very toxic gas that irritates the respiratory system and can have an adverse effect on human health in concentrations of as low as 1 ppm (parts per million). Coughing and vomiting will occur at 30 ppm and lung damage can occur at the 60 ppm levels of concentration. At 1000 ppm, chlorine can be fatal after a few deep breaths of the gas. In fact, chlorine is so deadly that it was actually used as a chemical weapon in both World War I and the Iraq War.
Most cities in the United States deliver chlorinated water in the 2-4 ppm concentration range. While this level of chlorine in your shower and bath water may not make you sick, it is still a potential health hazard and possible carcinogen. Research has shown that chronic exposure to chlorine concentrations of around 5 ppm caused respiratory complaints, corrosion of the teeth, inflammation of the mucous membranes of the nose, and increased susceptibility to emphysema, pneumonia and tuberculosis in workers. Animal studies have reported decreased body weight gain, eye and nose irritation, and effects on the respiratory tract, liver, and kidneys from chronic inhalation exposure to chlorine. Studies published in Nature and Health magazine indicate the likelihood that regular exposure to chlorinated water can even promote the aging process of the skin, much like extended exposure to sunlight.
The average person receives 50% of their chlorine exposure from taking a bath or shower. To be safe, a chlorine shower filter should be installed in every bathroom to protect yourself and your family from this toxic chemical. |
