Submerged macrophytes successfully restored a subtropical aquacultural lake by controlling its internal phosphorus loading
2021, Environmental PollutionCitation Excerpt :Although OP levels in the sediment slightly declined after restoration, this was still a crucial source of bioavailable P in Lake Datong because half of the OP components can be transformed into bioavailable P (Rydin 2000). Owing to the relatively stable structure and complicated composition of OP, macrophytes are more difficult to use in the short-term (Jin et al., 2008). However, OP could undergo more significant changes over time and be an important pool of potentially releasable P. Previous studies have shown that OP is largely related to sedimentation of organic matter (OM) (e.g., the detritus of macrophytes and phytoplankton) (Yuan et al., 2020).
Chemicals in Waste: Household Hazardous Waste
2019, Waste: A Handbook for ManagementCharacteristics of dissolved organic phosphorus inputs to freshwater lakes: A case study of Lake Erhai, southwest China
2017, Science of the Total EnvironmentCitation Excerpt :These sediment properties therefore help to explain why most P was released from sediments in the middle part of Lake Erhai in the dry season (Liu et al., 2015). The concentrations of bioavailable organic P were about 8 times greater than those of inorganic P in sediments from 20 lakes in the middle to lower reaches of the Yangtze River, China (Jin et al., 2008). In comparison, the EHP load released from Lake Erhai sediments was about half of the SRP load.
Processes and their explanatory factors governing distribution of organic phosphorous pools in lake sediments
2016, ChemosphereCitation Excerpt :Summarily, the labile OP pools were negatively correlated to ammonium and positively correlated to nitrate, the correlations were of the opposite direction for the less labile OP pools. Furthermore, similar results were reported that the decreasing percentage of LOP (NaHCO3-OP, extracted by NaHCO3) was found in oxidizing zone; while the increasing percentage of Re-OP and the transformation trend of HAOP to Re-OP were observed in anaerobic zone of the sediment profile, as well as the transformation of FAOP to HAOP (Jin et al., 2008; Zhang et al., 2008; Zan et al., 2011; Fan et al., 2013; Xu et al., 2013). As a result of the increasing recalcitrant of OP in the sediments as the early diagenetic processes proceeded (Fan et al., 2013; Xu et al., 2013), these findings may be explained by that the ammonification and mineralization govern the degradation of labile and moderate labile OP pools and thereby the accumulation of nonlabile OP pools.
