Concentrations of vinyl chloride on day 40 after adding WPE, l-lactic acid, l-tartaric acid, or syringic acid in the PCE degradation test. The result for the control (no addition) sample is also shown for comparison. Data are means of triplicate determination. ANOVA was performed to compare data. Values with different letters within each row are significantly different (Tukey’s test, p < 0.05)
