Monitoring of chlorine decay in public swimming pools in Medellín (Colombia).

The present work shows the evaluation of the decay of free residual chlorine in several public swimming pools in the city of Medellín, observing that a decrease in residual chlorine does occur. Some factors accelerate the decrease in the concentration of free residual chlorine in recreational water, such as the number of bathers in the pool, the pH, and the temperature of the water. For this reason, the concentration of the disinfectant rapidly decreases to an extent that the health of swimmers could be put at risk.

Clinical practice guidelines: Oral health care for children and adults living with epidermolysis bullosa.
