Fig. 2. Spatial and temporal variations of different physico-chemical properties of sediment. The numbers in SA08, SA09, SA14, SA16, and SA20 represent different numbers of years since rehabilitation. TN (%) = total sediment nitrogen content, TP (%) = total sediment phosphorus content, SOM (%) = sediment organic matter content, Salinity (‰) = the salinity content of sediment interstitial water, Cd (mg kg-1) = total sediment Cd content, Zn (mg kg-1) = total sediment Zn content, Cu (mg kg-1) = total sediment Cu content, Ni (mg kg-1) = total sediment Ni content, Cr (mg kg-1) = total sediment Cr content, Pb (mg kg-1) = total sediment Pb content, pH, C:N = the ratio of TC and TN.
