The Comparison of Phosphorus Pools from the Sediment in Two Bays of Lake Dianchi for Cyanobacterial Bloom Assessment

Abstract: The different pools in the sediment from two bays with different scales of cyanobacterial bloom were studied to assess the trophic status. With large scale of cyanobacterial bloom in Haigeng bay the concentrations of different phosphorus fractions were higher than the corresponding concentrations in Macun bay, and especially WSP and AAP are the most evident, which indicates that there are more available and potential available phosphorus in Haigeng bay. The adsorption experiment also shows that the sediment in… Show more

“…The c EPC0 values were larger than the SRP concentrations in the lower reaches of the <63µm 0% <63µm 50% <63µm 100% Amount of sorbed P( mg.kg -1 ) P equilibrium concentration ( mg l -1 ) Fig. 7 Adsorption isotherms for phosphorus on the floodplain sediments of the Hanjiang River at different grain-size distributions Hanjiang River (Xie and Dou 2005), so the sediments would release SRP into the water as a source of phosphorus.This result matchs that reported by Hu et al (2006). Values of ortho-phosphate phosphorus (PO 4 -P) in excess of 0.03 mg.l −1 in river waters are believed to lead to eutrophication (Vermont et al 2002).…”

“…Anthropogenic activities around the lake, especially Caohai, are intensive, so industrial, agricultural and domestic wastewater contribute to the elevation of As in the lake to some extent, as seen with the higher mean total As content of nearly 10 lg L -1 in Caohai compared with 7 lg L -1 in Waihai (Table 1). The results are generally consistent with the pollution status of Lake Dianchi (Hu et al 2006).…”

“…The lake is in a hypereutrophic status, with severe algae blooms occurring annually over the past two decades. The nitrogen and phosphorus contents were found to decrease gradually from the north to south, which is consistent with the eutrophic status of the lake (Hu et al 2006). Arsenic is a chemical analogue to phosphorus, and the relationship between phosphorus with eutrophication and the interaction of As and phosphorus has been documented in many lakes (Martin and Pedersen 2004;Rahman et al 2008).…”

“…The release of phosphorus from the sediment to lake water occurs either as the mobilization of phosphorus from H. Jun Institue of Hydroecology, Ministry of Water Resources & Chinese Academy of Sciences, Wuhan, China e-mail: xhujun@gmail.com suspended sediment particles or after mobilization into the dissolved P-pool in sediment pore water and the subsequent upward transport of the dissolved species into the water column (Boström et al 1988). The present trophic status of lakes is usually dependent on the P-concentration in the water, while the future trophic status, can be greatly influenced by the phosphorus content of lake sediments (Hu et al 2006;Hu et al 2007;Kaiserli et al 2002). At the present time, it is the pollution caused by internal phosphorus loading that is attracting attention (Rydin 2000; Van der Molen et al 1998).…”
