Swimming pool imperfections: Disinfection by-products from skin and urine

Date: Jul 16, 2012

Author: Steve Down

New disinfection by-products identified in swimming pools are mainly halophenols and halonitrophenols that originate from the chlorination of human urine and skin, so swimmers should avoid urinating in the water, say Chinese researchers
