Table 1: _Cont._OMP degradation and transfer into aquatic environment depends on the electron donating or withdrawing groups as well as hydrophobicity of OMPs [75]. The major physicochemical properties of OMPs include volatility, solubility, molecular weight, hydrophobicity (Kow), sludge adsorption and biodegradation, electron-withdrawing group (EWG) and electron-donating groups (EDG) [47]. [PERSON] et al. (2015a) evaluated the removal of 30 OMPs and report that more than 85% removal was observed for hydrophobic OMPs.
