Factors that Determine DBP Levels


The conditions that determine production and air levels of DBPs have been suggested to depend on several factors: * Number of swimmers in the AQUATIC VENUE and their associated hygiene; * CHLORINE concentration; * Water temperature; * Concentration of organic precursors in the AQUATIC VENUE water; * Chemical structure of the organic precursors; * Bromide content; * Indoor air circulation; * The extent of out-gassing of volatile DBPs; * pH; * Level of water agitation (undisturbed vs. being sprayed); and * Concentration of inorganic chloramine from the fill water. Further research is needed to determine how much DBPs are being created in AQUATIC VENUE water, including the production and retention rate.
