The post-column reaction GC used was a combination of Agilent 7890A GC-FID (Agilent Technologies Inc., Santa Clara, CA, USA) and a Standard Materials Calibration System TE-1000 (Horiba Stec Co., Ltd., Kyoto, Japan). Next, to ensure the complete oxidation of organochlorine compounds, some aluminum components of the heating furnace were replaced with stainless-steel components (SUS 430), allowing the system's use at temperatures up to 650°C. A mass flow controller, SEC-Z512MGX (Horiba Stec Co., Ltd.), was used to keep the carrier gas flow rate constant. The operating conditions of the post-column reaction GC are summarized in Table S1 (Supporting Information).

The commercial standards of 28 VOCs were purchased from several manufacturers. Detailed information regarding the manufacturers, purities and uncertainties of the purities are given in Table 6 . Pesticide residue grade methanol was purchased from J.T. Baker, USA. The stock standard solutions were 27 mixed VOCs standard solution (IRMM, 100 µg/mL) and vinyl chloride standard solution (2000 µg/mL, Supelo, USA). The internal stock standard solutions were fluorobenzene and 1,4-dichlorobenzene D4 (IRMM, 1000 and 1000 µg/mL, respectively).
The VOCs spiking solution was prepared gravimetrically using a calibrated Mettler Toledo analytical balance (AE-240, 205 g capacity, resolution of 0.01 mg, Switzerland). The purities of the 28 VOC commercial standards were verified by a calibrated gas chromatography with flame ionization detection (Agilent 7890A GC-FID, USA). Homogeneity and stability studies of VOCs spiking solution were performed on a calibrated Agilent 7890A gas chromatograph coupled with an Agilent 5975C mass spectrometer (Agilent 7890A GC-5975C MS, USA). Analysis of the water MCRM was performed on a calibrated purge-and-trap Agilent 7890A GC-5975C MS.

The reaction intermediates of chlorophenols were identified by Thermo Fisher ITQ-900 GC-MS (Gas Chromatograph-Mass Spectrometry) with a 30 m TG-1701MS column (0.25 mm  0.25 mm).
The concentration of chlorophenols and their intermediate products were analyzed by Agilent-7890 A GC-FID (Gas Chromatograph-Flame Ionization Detector) equipped with a 30 m DB-1701 column (0.32 mm  0.25 mm). The chromatographic conditions were given in Supplementary Material (Text SM3). The conversion was defined as Eq. (S1), while the HDC reactivity was evaluated using HDC rate, which was calculated as Eq. (S2).

About PubCompare
Our mission is to provide scientists with the largest repository of trustworthy protocols and intelligent analytical tools, thereby offering them extensive information to design robust protocols aimed at minimizing the risk of failures.
We believe that the most crucial aspect is to grant scientists access to a wide range of reliable sources and new useful tools that surpass human capabilities.
However, we trust in allowing scientists to determine how to construct their own protocols based on this information, as they are the experts in their field.
