“…In last two decades or so, annual mean total nitrogen (TN) and TP concentrations have approached 3.0 and 0.1 mg· L −1 , respectively. The greatest mean annual concentration of TN was 5.34 mg L −1 in 2004, while greatest mean annual concentration of TP was 0.21 mg L −1 and occurred in 2000 (Ye et al 2011). In May 2007, a huge algal bloom broke out and significantly impacted the supply of fresh water to about 6.1 million people in Wuxi City (Ye et al 2011).…”

Debris from aquatic macrophytes and algae are important recycling sources of phosphorus (P), which can result in continuing blooms of algae by recycling bioavailable P in the eutrophic lakes. However, knowledge of forms of P in aquatic macrophytes and algae and their contribution to internal loads of P in lakes is limited. Without such knowledge, it is difficult to develop appropriate strategies to remediate and or restore aquatic ecosystems that have become eutrophic. Therefore, in this work, P was extracted from six types of aquatic macrophytes and algae collected from Tai Lake of China and characterized by use of solution 31 P-nuclear magnetic resonance (NMR) spectroscopy. When extracted by 0.5 M NaOH-25 mM EDTA, extraction recovery of total P(TP) and organic P(P o ) exceeded 90 %. Concentrations of P o in algae and aquatic macrophytes were 5552 mg kg −1 and 1005 mg kg −1 and accounted for 56.0 and 47.2 % of TP, respectively. When P o , including condensed P, was characterized by solution 31 P-NMR P o in algae included orthophosphate monoesters (79.8 %), pyrophosphate (18.2 %), and orthophosphate diester (2.0 %), and P o in aquatic macrophytes included orthophosphate monoesters (90.3 %), pyrophosphate (4.2 %), and orthophosphate diester (5.5 %). Additionally, orthophosphate monoesters in algal debris mainly included β-glycerophosphate (44.1 %), α-glycerophosphate (13.5 %), and glucose 6-phosphate (13.5 %). Orthophosphate monoesters in aquatic macrophytes mainly included β-glycerophosphate (27.9 %), α-glycerophosphate (24.6 %), and adenosine 5′ monophosphate (8.2 %). Results derived from this study will be useful in better understanding nutrient cycling, relevant eutrophication processes, and pollution control for freshwater lakes.

“…Higher water temperature can impair the habitat of a wide range of aquatic organisms from invertebrates to salmonids (Langan et al, 2001;Caissie, 2006;Isaak et al, 2012;Markovic et al, 2013;Null et al, 2013a,b), as well as degrade water quality such as decreased oxygen-holding capacity, increased oxygen consumption, and enhanced formation of potentially toxic NH 3 (Webb and Nobilis, 2007;Pekárová et al, 2011;El-Jabi et al, 2014). Furthermore, increasing riverine heat flux has a great potential to aggravate eutrophication (including harmful algal blooms) and hypoxia in downstream lakes, estuaries and coastal waters (Liu et al, 2005;Ozaki et al, 2008;Ye et al, 2011;Rice and Jastram, 2015), as well as to impair their biological communities (Seekell and Pace, 2011).…”

s u m m a r yClimate warming is expected to have major impacts on river water quality, water column/hyporheic zone biogeochemistry and aquatic ecosystems. A quantitative understanding of spatio-temporal air (T a ) and water (T w ) temperature dynamics is required to guide river management and to facilitate adaptations to climate change. This study determined the magnitude, drivers and models for increasing T w in three river segments of the Yongan watershed in eastern China. Over the 1980-2012 period, T w in the watershed increased by 0.029-0.046°C yr À1 due to a $0.050°C yr À1 increase of T a and changes in local human activities (e.g., increasing developed land and population density and decreasing forest area). A standardized multiple regression model was developed for predicting annual T w (R 2 = 0.88-0.91) and identifying/ partitioning the impact of the principal drivers on increasing T w :T a (76 ± 1%), local human activities (14 ± 2%), and water discharge (10 ± 1%). After normalizing water discharge, climate warming and local human activities were estimated to contribute 81-95% and 5-19% of the observed rising T w , respectively. Models forecast a 0.32-1.76°C increase in T w by 2050 compared with the 2000-2012 baseline condition based on four future scenarios. Heterogeneity of warming rates existed across seasons and river segments, with the lower flow river and dry season demonstrating a more pronounced response to climate warming and human activities. Rising T w due to changes in climate, local human activities and hydrology has a considerable potential to aggravate river water quality degradation and coastal water eutrophication in summer. Thus it should be carefully considered in developing watershed management strategies in response to climate change.
