Abstract

In order to explore the environmental significance of the particulate organic as the source of stable isotopic carbon and nitrogen in suspended solids and sediments of the Lake in cold and arid regions, the contents of δ¹³C, δ¹⁵N and C/N ratio of suspended solids and surface sediments in Nanhai Lake during the ice-sealing period were determined in January 2019. The results showed that, δ¹³C, δ¹⁵N, C/N in the suspended organic matters varied in the range of -31.94‰~-27.87‰, 15.16‰~18.66‰, and 3.90~5.13, respectively, while in the sediments varied in the range of -25.39‰~-18.83‰, 7.04‰~13.66‰, and 7.66~12.23, respectively. The peak values of the δ¹³C and δ¹⁵N contents in the suspended organic substances appeared in the water entering area and the islands in the center of the lake, respectively, while in sediments, both the peak values appeard in the latter. The end-member mixing model showed, the suspended organic matter in the frozen period was mainly originated from the endogenous aquatic algae, which contributed 82.33% of the total suspended organic matters in the water conservation area, being consistent with the highest abundance of phytoplankton in the area. The main source of organic matters in the surface sediments was endogenous aquatic plants, which contributed 89.7% of the total organic matters in the water conservation area. Analyses showed that there was no significant correlation between suspended organic matter and δ¹³C, δ¹⁵N in the surface sediments during the freezing period. At low temperature, there exist significant negative correlation between the suspended δ¹⁵N and temperature (P<0.025) as well as nitrate nitrogen (P<0.019), positive correlation between the suspended δ¹⁵N and the nitrite nitrogen (P<0.034). These maybe due to the exogenous contribution rate and the isotopic effect of biological action. There was an extremely significant positive correlation between δ¹³C and COD in suspended matter (P<0.008), and a significant positive correlation between δ¹³C and salinity (P<0.046). The COD and suspended ¹³C are likely to have homology and have a certain environmental indication in the lake ice-sealing period.
