Ultra-trace analysis of hormones, pharmaceutical substances, alkylphenols and phthalates in two French natural mineral waters

► Examined the potential presence of 120 organic contaminants in two natural mineral waters. ► Alkylphenols, BPA, phthalates, hormones, and pharmaceuticals were not detected. ► No migration of targeted compounds from PET bottles occurred under test conditions. ► Complexity of reaching reliable measures at ultra-trace level for very pure matrices ► Laboratory background contamination by DEHP emphasized and very low LOQ reached
