A workplace bleach exposure incident was studied in 13 women to determine whether chlorine caused neurobehavioral and pulmonary functional effects. We compared neurophysiological and neuropsychological measurements in 13 chlorine-exposed women, 4.5 years after exposure, and 41 unexposed women. Reaction times, balance, blink reflex latency, color discrimination and several psychological tests were measured. Pulmonary function was assessed by spirometry. A profile of mood states and frequencies of 35 symptoms were obtained. Chlorine exposed women performed statistically significantly below unexposed women for simple and choice reaction times, balance with eyes open and eyes closed, color discrimination, grip strength, Culture Fair, digit symbol substitution, vocabulary, trail making B and pegboard. Profile of mood states scores and frequency symptoms were elevated. Respiratory symptoms were elevated but pulmonary volumes and flows were not reduced. Chlorine bleach exposure was associated with impaired neurobehavioral functions and elevated POMS scores and symptom frequencies. Alternatives to chlorine should be used.
