K. Cammann et K. Hubner, TRIHALOMETHANE CONCENTRATIONS IN SWIMMERS AND BATH ATTENDANTS BLOOD AND URINE AFTER SWIMMING OR WORKING IN INDOOR SWIMMING POOLS, Archives of environmental health, 50(1), 1995, pp. 61-65
The influence of working or swimming in indoor swimming pools on the c
oncentrations of four trihalomethanes (haloforms) in blood and urine w
as investigated. Different groups (bath attendants, agonistic swimmers
, normal swimmers, sampling person) were compared. The proportions of
trihalomethanes in blood and urine correlated roughly with those in wa
ter and ambient air. Higher levels of physical activity were correlate
d with higher concentrations. Within one night after exposure in the p
ool the blood concentrations usually were reduced to the pre-exposure
values. Secretion of trichloromethane in urine was found to be less th
an 10%.
