When athletes at this year's U.S. national swimming championships found themselves gasping for breath while competing at the indoor pool at Indianapolis University, event organizers said the culprit most likely was the disinfection byproducts (DBPs) from the chlorine meant to keep the pool clean. Swimmers' lung troubles - and other possible long-term health effects - generally have been attributed to breathing chloroform, trihalomethanes, and trichloramines, which form in such settings and volatilize at the water's surface. But new research published in
ES&T (DOI:
10.1021/es070871+) indicates that other byproducts hidden in the watery mix also might be to blame.

At the water's surface, swimmers breathe in a mix of volatilized disinfection byproducts, including some recently discovered to form in chlorinated swimming pools.

Comment: Electro-sensitivity, EMF and WIFI - one woman's saga
[...]Doctors say there is little scientific evidence to back up a link between EMF and poor health. They claim the symptoms, often attributed to flu or viruses, are psychosomatic.
But campaigners disagree. They reckon around 500 people are already being treated for ES [Electro Sensitivity] and as many as five per cent of the population could be affected.
