Phosphorus forms, their potential biodegradability in sediment and their potential environmental effects.

aSee phosphorus fractionation method in Table S2. bIn this fractionation method, according to a coarse division, pore water and loosely adsorbed P, redox-sensitive (iron-bound) P, and labile organic P are considered mobile (or reactive) phosphorus forms while refractory P, aluminium-bound P, and apatite-P are considered immobile phosphorus forms [25], [11]. cParticle size <0.4 µm. dParticle size >0.4 µm. e[26], [25]. fe.g. sugar phosphates, mononucleotides, phospholipids, inositol P. ge.g. sugar DNA-P, lipid P, teichoic-P. he.g. adenosine triphosphate. iBiodegraded to or chemically released phosphorus which is bioavailable. j[27]–[29]. k[30], [16].
