Effects of Nitrogen Trichloride (trichloramine) On The Human Lung
Nitrogen trichloride has been directly linked as a factor causing asthma in two lifeguards and a swimming teacher. A study of 624 swimming pool workers found a significant correlation between upper respiratory symptoms and their total exposure to nitrogen trichloride. The study also found an excess risk in the workers for the specific symptoms indicative of asthma. In a study by Alfred Bernard's group, two hours exposure to an average concentration of 0.490 mg/m3 of nitrogen trichloride above a swimming pool was found in both children and adults to significantly increase the levels of the alveolar surfactant associated proteins A and B, which indicate hyperpermeability of lung epithelium. In other words, exposure to nitrogen trichloride was found to weaken the protective nature of the surface of the lungs.

Famous quotes containing the words effects, human and/or lung:
“Upon the whole, necessity is something, that exists in the mind, not in objects; nor is it possible for us ever to form the most distant idea of it, consider’d as a quality in bodies. Either we have no idea of necessity, or necessity is nothing but that determination of thought to pass from cause to effects and effects to causes, according to their experienc’d union.”
—David Hume (1711–1776)
“He had discovered a great law of human action, without knowing it—namely, that in order to make a man or a boy covet a thing, it is only necessary to make the thing difficult to attain. If he had been a great and wise philosopher, like the writer of this book, he would now have comprehended that Work consists of whatever a body is obliged to do and that Play consists of whatever a body is not obliged to do.”
—Mark Twain [Samuel Langhorne Clemens] (1835–1910)
“Dylan used to sound like a lung cancer victim singing Woody Guthrie. Now he sounds like a Rolling Stone singing Immanuel Kant.”
