¹ The relative abundances (%) of the phosphonylated/phosphorylated products were calculated on the basis of the total P dissolved and by the peak integration method, as reported previously [24,25,26]; ^TC-O-P means total C-O-P (carbon-oxygen-phosphorus) type organophosphorus compounds e.g., total sum of organic phosphates and phosphites for that particular reaction (and may not represent the exact sum due to rounding). The blank lines in the table show that these compounds are not present in the sample. BDL signifies below detection limit.
