“…The use of lipid biomarkers to distinguish the sources of organic matter has been widely used in lacustrine SOM studies (Arnold et al., 2019; Randlett et al., 2017; Tuo et al., 2011). Compared with the apportionment of organic matter by using C/N, δ 13 C, and HI, recent studies mainly focus on certain aquatic organic matter derived from Cyanobacteria , Diatomeae , and bacteria (Zhang et al., 2017).…”

In recent years, some researchers have begun to use sediment cores in lakes to study the impact of historical primary productivity on the migration and enrichment of pollutants, and then analyze the "biological pump" role of phytoplankton. Outridge et al. (2005Outridge et al. ( , 2007 used the Rock-Eval pyrolysis parameters to study the primary productivity history in Arctic lakes, while also analyzing the mercury concentration in the deposition cores. They found that climate warming for algae growth played the role of a "biological pump" on mercury. Stern et al. (2009) investigated some lacustrine systems and also found the effect of algal "biological pump" on mercury concentrations in the sediment cores while emphasizing that historical changes in primary productivity were mainly due to global temperature warming. Carrie et al. ( 2009) also found the effect of global warming on lake historical productivity, while increased algae acted as a "biological pump" for mercury, enhancing its accumulation in sediments and aquatic fish. Söderström et al. (2000) found higher polychlorinated biphenyl (PCB) and dichlorodiphenyltrichloroethane sedimentary fluxes and higher PCB concentrations in the surface sediments of eutrophic lakes than those of oligotrophic lakes, and most of the transport depended on phytoplankton. Jeremiason et al. (1999) selected a pair of lakes of similar size and catchment area for comparison, and also found

Multiple organic proxies and lipid biomarkers in the sediment core samples collected from Luoma Lake and Hongze Lake in Jiangsu are used to expound the relationships of global warming with lacustrine productivity and depostion of polycyclic aromatic hydrocarbons. Total organic carbon, S2, and hydrogen index in sedimentary organic matter were obtained with the Rock-Eval analysis. Nutrient status such as total phosphorus and total nitrogen was measured in the sediment cores. The

“…Benthic photosynthesis is also a source of dissolved oxygen that helps to mitigate internal loading of P, and it probably contributes to bulges in dissolved oxygen concentrations at depth in both ponds (Colman and Waldron 1998, Colman and Friesz 2001, ESS Group 2014-2017, Walker 2017. Eutrophication and associated clouding of the water column can inhibit benthic vegetation through shading and thereby lead to a self-amplifying cycle of increasing oxygen depletion, internal loading, and greater uptake of a lake's nutrient budget by phytoplankton (Wagner et al 2000, Arnold et al 2019. At Walden, benthic meadows represent far more biomass than the phytoplankton, meaning that a large reservoir of nutrients that is currently trapped on the bottom could become available to plankton if the macrophytes are lost due to shading Waldron 1998, Colman andFriesz 2001).…”
