Symptoms could appear 24 to 48 hours after inhaling water.

Legionnaires' disease comes from inhaling water vapor that contains the Legionella bacteria.

People are infected with Legionnaire's Disease after inhaling water droplets that contain legionella bacteria.

Risk depends on dose: inhaling water is fatal if you inhale enough of it.

The suspected cause of death is "dry drowning," a rare condition in which there is a delayed physical reaction to inhaling water.

Garon Vega's 2-year-old son, Gio, became ill at night after inhaling water at their Colorado community pool earlier in the day, Vega told CNN affiliate KTRK-TV.

The cowl has a tiny hole at the nose, but sweat collects there, so if you try and breathe through your nostrils, it feels like you're constantly inhaling water.

"We essentially found that using e-cigarettes is not equivalent to inhaling water vapor; in fact, it can exert acute, detrimental effects on (blood vessels) even when the liquid does not contain nicotine," Dr. Alessandra Caporale of the University of Pennsylvania Perelman School of Medicine in Philadelphia, the study's first author, told Reuters Health in an email.

Lower sides of the body have a row of black, elongate, bar-like markings. A small dorsal fin is set far back near the tail. Sphoeroides maculatus, like others in the puffer family, "puffs up" into a ball in self-defense by inhaling water into a special chamber near its stomach. They will puff up with air, if taken out of the water.

They can produce very high flow rates for a small pressure differential, and particularly for a relatively small cracking pressure. They are generally more complicated and expensive to service. Exhaled gas leaves the demand valve housing through one or two exhaust ports. Exhaust valves are necessary to prevent the diver inhaling water, and to allow a negative pressure difference to be induced over the diaphragm to operate the demand valve.

The juvenile must land on clean gravely or sandy substrates if it is to successfully grow. Attached to the substrate, juvenile freshwater pearl mussels typically burrow themselves completely into the sand or gravel, while adults are generally found with a third of their shell exposed. Should they become dislodged, freshwater pearl mussels can rebury themselves, and are also capable of moving slowly across sandy sediments, using their large, muscular foot. The freshwater pearl mussel grows extremely slowly, inhaling water through exposed siphons, and filtering out tiny organic particles on which it feeds.

Air flow through the exhaust valve Duckbill exhaust valve for Draeger twin hose regulator Synthetic elastomer mushroom exhaust valve on demand valve Exhaust valves are necessary to prevent the diver inhaling water, and to allow a negative pressure difference to be induced over the diaphragm to control the demand valve. The exhaust valves should operate at a very small pressure difference, and cause as little resistance to flow as reasonably possible, without being cumbersome and bulky. Elastomer mushroom valves serve the purpose adequately, though duckbill valves were also common in twin-hose regulators. Where it is important to avoid leaks back into the regulator, such as when diving in contaminated water, a system of two sets of valves in series can reduce the risk of contamination.

Waterborne disease outbreaks may be associated with recreational water, water intended for drinking, water not intended for drinking (non-recreational water, for example, from cooling towers or ornamental fountains) and water of unknown intent. In order for a waterborne disease outbreak to be included in WBDOSS there must be an epidemiologic link between two or more persons that includes a location of water exposure, a clearly defined time period for the water exposure, and one or more waterborne illnesses caused by pathogens such as bacteria, parasites and viruses, or by chemicals/toxins. Common routes of exposure to waterborne pathogens include swallowing contaminated water, inhaling water droplets or airborne chemicals from the water, and direct physical contact with contaminated water. Epidemiologic evidence must implicate water or volatile compounds from the water that have entered the air as the probable source of the illness.
