Inhalable Water Droplets Preliminary studies by engineers at the University of Cincinnati and the Oak Ridge Institute for science and education, also in Cincinnati, indicate that some water-saving shower nozzles produce water droplets so small they can be inhaled, exposing anyone using the shower to several different health hazards. Another threat may be possible as well. Previous research has shown that the droplets can contain microbes that live inside the warm, wet interior of shower nozzles. When the faucet is turn on, these microbes are swept out through the nozzles. If these droplets are inhaled, the microbes could pose a threat to people who are with asthma and other respiratory problems. 1.The first paragraph is a question to which the author hopes to have a positive answer from the reader. 2.Shower nozzles shower nozzles that produce water droplets, big and small, can expose anyone using the shower to health problems. 3.The chemicals contained in water kill bacteria to make it safe for drinking. 4.The problem that inhalable water droplets produce is that they may expose people with respiratory problems to health hazards. 5.The adjustable type of nozzles are less dangerous than the fixed one. 6.People with asthma and other respiratory problems should avoid taking showers. 7.To overcome the problem caused by inhalable water droplets, Sethi, per haps with some other researchers, is drawing up standards for safe shower head designs.
