A freshwater and three seawater swimming pools located in France were investigated.
Trihalomethanes, haloacetic acids, haloacetonitriles and other DBPs were measured.
Predominance of brominated DBPs in seawater vs. chlorinated ones in freshwater pool
The freshwater pool exhibited more mutagenic potency than the tested seawater pool.
The higher mutagenicity of the freshwater pool is related to its higher DBP content.
