- Abstract
We have developed and evaluated a method for quantifying chloroacetic acids (monochloroacetic acid, dichloroacetic acid, and trichloroacetic acid) in mineral water (MW) products. After a performance evaluation, we surveyed the chloroacetic acids concentrations in 150 kinds of MW products purchased on the Japanese market in 2016. The recovery rates of chloroacetic acids from the 150 spiked samples prepared from purchased MW products ranged from 90% to 110%. These results suggest that the analytical method is highly applicable to MW products. Monochloroacetic acid (MCAA) was identified in three different samples at a detection rate of 2.0%; dichloroacetic acid (DCAA) in seven different samples at a detection rate of 4.7%, and trichloroacetic acid (TCAA) in one sample at a detection rate of 0.7%. No product was found to have a chloroacetic acid level that exceeded the World Health Organization guidelines for drinking-water quality (MCAA: 0.02 mg/L, DCAA: 0.05 mg/L, and TCAA: 0.2 mg/L).
