title: Gas chromatographic-mass spectrometric characterization of volatile organic compounds in Barcelona tap water.
abstract: Barcelona's tap water is supplied by the Llobregat and Ter rivers, which have significant differences in raw water quality. Volatile organic compounds (VOCs) from Barcelona tap water were isolated by closed-loop stripping analysis (CLSA) and identified and determined by gas chromatography-mass spectrometry. The results showed that the Ter river gives the better quality tap water. VOCs, in particular solvents, phosphates, hydrocarbons, C3 and C4 alkylbenzenes and surfactant-related compounds such as C10-C13 alkylbenzenes and non-ionic compounds such as polyethoxylated nonylphenols and their brominated derivatives are present at the ppb level. The last two types of compounds have not previously been reported using the CLSA technique.
