Abstract

Abstract

Phosphorus is an important biogenic element playing a key role in primary production in estuarine and coastal environments. Knowledge of the speciation and transformation of phosphorus in sediments contributes to a better understanding of the ecosystem dynamics in these regions. Surface sediment samples were collected in the Changjiang Estuary and adjacent shelf in March, 2013, and were separated into different size fractions via water elutriation. P speciation was analyzed by a modified sequential extraction method (SEDEX) to obtain six sedimentary P forms:exchangeable or loosely-sorbed P(Ex-P), organic P(Or-P), Fe-bound P(Fe-P), authigenic P(Au-P),detrital P(De-P) and refractory P(Re-P) in order to investigate the distribution and transformation of different phosphorus forms in the sediments of this area. The total phosphorus (TP) in sediments ranged from 14.0-18.4 μmol/g, and De-P was the major form and accounted for 54.5% of the TP, followed by Or-P and Re-P, which accounted for 15.1% and 13.1%, respectively. The contents of phosphorus forms in different size fractions were different. Ex-P, Or-P, Fe-P, Au-P and Re-P decreased gradually with increasing grain size, while De-P was concentrated in coarser particles (more than 32 μm). Based on the mass distribution of phosphorus speciation, less than 32 μm fractions gradually increased from Changjiang Estuary to Zhe-Min Coast and decreased seaward, while the variation tendency of more than 32 μm fractions was opposite, reflecting the selective transport of phosphorus of different forms. With the increase of particle size, TOC to Or-P (TOC/Or-P) ratios first decreased and then increased. High TOC/Or-P values in the larger size fractions were possibly caused by the high terrestrial OC contributions in this fraction, while in fine particles, high TOC/Or-P values are largely attributed to the more efficient transformation and remobilization of Or-P, indicating preferential regeneration of Or-P relative to OC. This study shows that a more comprehensive understanding of the phosphorus cycle in these dynamic estuarine and coastal environments can be obtained from a size fractionation perspective.
