Abstract With the situation of water pollution worsening, human health problems on their own are also increasingly concerned about the health of shower water is increasingly attracting attention, research and development of shower water filters to demonstrate the broad market prospects. This paper describes the origin of health problems, shower water and the current world, the shower filter research and development of the situation.

In recent years, due to the growing concern about the urban water supply situation, coupled with urban water supply in the secondary pollution, these factors have led to water disinfection by-products contain many harmful organisms, this will pose a threat to human health and hazards.

1, shower water can not be ignored health problems

Household water supply in the micro-pollutants usually enter the body through three channels: drinking, breathing and skin absorption. According to MartinFox and others view the water of harmful chemicals into the body by drinking from the digestive system may not be the most important ways, these three channels (for drinking, breathing and skin absorption) will pose a potential hazard to the human body [1]. We used to talk about water and human health, often only pay attention to the quality of drinking water and its treatment, and harm of the latter two of their due attention.

Water projects, according to senior professionals, 100 Nuoken water purification equipment Co., Ltd (Paragon WaterSystems group LimitedCompany) president John Douglas (John Douglas) introduced, in the shower, we absorb pollution matter much more than drinking water. Shower, hot water opens the pores of the skin, chlorine and other pollutants will swoop. Contaminants absorbed through the skin, and then directly into the blood circulatory system, digestive system like water through the roundabout to enter the circulation, have the same hazards. Another noteworthy place is the bath a lot of steam inhalation. In the shower room, hot water in a small space generated a lot of steam, causing the body easily inhaled chlorine and other gases.

In fact, a person through respiratory inhalation of chemical substances entering the mouth than the 6 to 80 times more. Radon in water, heat will evaporate, enter the body through breathing, will form a long-term accumulation of lung cancer, U.S. Environmental Protection Agency (USEPA) in 1988 proposed the maximum radon concentration of pollutants in water target (MCL G) is zero. J ulianB.Andelman et al study shows that when using a containing TCE (3-chlorophenyl ethane) and the shower water, breathing the chemical potential is much larger than the direct consumption of [2].

Volatile substances contained in water most of volatile organic compounds (VOCs), the U.S. Environmental Protection Agency has launched an assessment of the VOCs intake mathematical model. Cathern and others calculated using this model concluded that, if the assumed adult body weight 70kg per day of drinking water for the 2L, shower water per day for the 190L, the shower of VOCs during the intake quantity and water channels through the photo into approximately the same amount. Martin Fox and others also believe that after study, skin absorption and respiratory exposure should not be overlooked two important ways hazardous to their health.

View of the shower process, water will be harmful to organisms by means of breathing and skin absorption into the human body, so the developed countries and China has started to take shower filter research and development.

2, the main performance shower filter

2. 1 resist against radon

Gratifying is that manufacturers have begun to realize radon produced by the shower of water hazards, and started development of filtration products to remove radon. Now, there are already some certified radon filter can be purchased in the market. Radon is a colorless, odorless gas, it is from the ground by the natural radioactive decay of uranium and produce. It will dissolve and accumulate in underground water sources. Radon can enter the soil in various buildings. Homes, offices, schools may be violated. Radon content of air in the building will be cumulative. Users who use groundwater sources, such as use of well water, and pay attention to radon in indoor air and water. However, those who use surface water sources, such as use of river water, lake, reservoir water users do not need to worry about this issue. Because radon time even before reaching the taps into the air, when water containing radon shower, washing and cooking, the water, radon is released into the air. This process is like drinking carbonated beverages, open the cap and release carbon dioxide. According to information released by EPA last year, in a certain period of time excessive inhalation of radon, there may be many causes of cancer. When radon decays to form radioactive particles when inhaled into the lungs would be. As these particles continue to decay, they release a little energy, and life in the future respiratory hazards, increase the possibility of terrible lung cancer. Not all exposure to radon gas in people who will get lung cancer, but smokers are more likely to suffer some of.
