EFFECTS OF ACUTE EXPOSURES
Pool chemical–associated health events result in >4.500 emergency department visits annually during 2008-2017 in US, as reported by the CDC, and over one-third were children or teenagers. Irritated eye, nose and throat symptoms, and asthma, are the most frequent symptoms in swimmers and workers of indoor swimming-pools caused by CBPs; particularly NCl3 causes the most irritative symptoms13,14. A significant concentration-response relation was found between NCl3 exposure concentrations and irritant eye, nasal, and throat symptoms15.
