“…The C/N ratio in the Wular Lake sediments ranges from 5 to 18 (average = 18), suggesting that the main source of the OM is managed by autochthonous algal matter and terrestrial OM mixing. In their studies, Meyers and Teranes (2001) and Achyuthan et al (2020) suggest that C/N ratios between 4 and 10 suggest an algal source, while those above 10 suggest a mixed source from algal and vascular land plants.…”

improved abrasion rates and ensuant settling of detritus into the lake are closely linked with the prominent physical weathering over chemical weathering. The new finding of the present study is that sediments represent an unweathered basalt compositional trend, plausible provenance from mafic rocks, experiencing low to moderate degree of chemical weathering. The study found that increased encroachment within the lake catchment due to continued anthropogenic forcing is the primary source contributing the organic matter (OM) as well as the higher levels of Cl, NO 3 , SO 4 , and P to the lake. These findings corroborate with the land use-land cover changes (from the last 50 years) within the lake catchment in significantly deteriorating the lake system. The study recommends that the ongoing conversion of lake peripheral areas into urban settlement and agro-horticulture land by filling activities should be restricted.
