[The study of contents of trihalomethanes in brine of a therapeutic swimming pool and in the swimming pool hall air].
The chlorination of iodide-bromide brines during exploitation of therapeutic pools at health resorts brings a hazard of generation of toxic trihalomethanes (THMs), especially bromide derivatives. The study was undertaken to establish the time changes of THM concentration in the pool brine and air in the pool hall. In the pool brine the concentration of THM increased from 40 mg/l at the beginning of the exploitation cycle up to 100 mg/l after 2 months of recirculating the pool water. In the pool hall air the concentration of THM varied from approximately 6 micrograms/m3 to 16.32 micrograms/m3. The values are the concentrations of total THMs per CHCl3, and fall within the range of limits currently admissible for drinking water (so in sport and recreational pools as well). However, they are from 2 to 5 times higher than the admissible level of THMs in indoor pools given in German standards DIN. An interesting finding was over 80% contribution of CHBr3 in the total THMs determined in the pool brine and its 55-59% contribution in the total THMs determined in the pool hall air.
