Bibliometric analysis is an important tool for the assessment of research trends on a topic of interest. With the rising demand for research on sediments, the current work is aimed to evaluate the number of publications, major countries involved, and major thrust areas of research using the search keywords “sediment organic carbon” and “sediment heavy metals.” The bibliometric recovery of 1367 publications was done from the Scopus database during the study period of 23 years, that is, from 2000 to 2022 (till August) and the analyses were performed using VOSviewer and Biblioshiny software. The result showed a greater number of publications on sediment organic carbon than the heavy metals. Research articles were the most preferred publication type as compared to book chapters, conference proceedings, review articles, and so on. No particular journal was found to have a significant impact on the topic of research, but Chemosphere and Marine Pollution Bulletin showcased the highest impact on publication with an H‐index score of 36 each. While, China dominated the research on the concerned topic followed by India and the United States, a low level of inter‐country collaboration was however detected in the analysis suggesting a regional influence on sediment‐related topics. “Risk assessment,” “Geo‐accumulation index,” and “Potential ecological risk” were the major focal areas that were associated with the assessment of sediment quality and heavy metal accumulation. It can be concluded that sediment related research has been regionally focused. More inter‐country collaborations can aid in trans‐disciplinary research related to sediments in the future.

Changes in the environment, aiming at agricultural intensification, progressive urbanisation and other forms of anthropopression, may cause an increase in soil erosion and a resulting increase in the pollution inflow to surface water. At the same time, this results in increased nutrient pollution of bottom sediments. In this study, the concentrations of total nitrogen (TN), total phosphorus (TP), total organic carbon (TOC), calcium (Ca), iron (Fe) and potassium (K) were analysed using bottom sediment samples collected at 39 sites located along the entire length of the Warta River and its tributaries. Agricultural use of land adjacent to rivers was found to significantly degrade sediment quality, while anthropogenic land use (as defined by Corine Land Cover classification—CLC), unlike previous studies, reduces the pollution loads in the bottom sediments. Forest use also contributes to the reduction of the pollution load in sediments. It was found that the significance of the relationship between pollutant concentrations and land use depends on the length of the river–land interface. According to the analyses, the level of correlation between the analysed constituents depends on the use of land adjacent to rivers. The impact of agricultural land use has the strongest effect in the 1 km zone and 5 km in the case of anthropogenic land use. The results showed that the variability of total phosphorus TP concentrations is strongly correlated with the variability of iron concentrations. SPI values indicate that the risk to sediment quality is low due to TOC and Fe concentrations. In contrast, the risk of sediment pollution by TN and TP shows greater differentiation. Although the risk is negligible for 40% of the samples, at the same time, for 33% of the samples, a very high risk of pollution with both TN and TP was found.

“…In addition, the guano of birds also serves as the prominent source of protein to the wetland sediments(Joy et al 2019). PRT contents are subjected to intense microbial activity resulting in lowering of concentration compared to other organic fractions in aquatic systems(Mathew et al 2019). Total lipids are the third most dominant fraction of labile OM in the study region.…”

Spatio-temporal distribution dynamics of various biochemical components in Thrissur Kole wetland were analysed to assess the quality of organic matter (OM) and trophic status. Thrissur Kole wetland forms the part of the Vembanad wetland system, located in the southwest coast of India. Surface sediment samples were collected from sixteen sites during non-monsoon (February 2019) and monsoon (August 2019) seasons. Concentration of biochemical parameters displayed a trend as follows: total carbohydrates > total protein > tannin & lignin > total lipids. Observed chlorophyll pigment concentration in sediments was as follows: Chl a > Chl b > Chl c (in both seasons). Intermediate values of C/N ratios indicated a mixed origin of OM. Majority of stations exhibited lower values of protein to carbohydrate ratios which revealed the occurrence of aged sedimentary OM. Lower values of lipid to carbohydrate ratio indicated lower nutritional value of the organic content. The lower content of labile OM, low biopolymeric carbon to total organic carbon ratio and low algal contribution to the biopolymeric carbon suggested that a bulk fraction of OM exist as refractory. Trophic state of the wetland system was evaluated as hypertrophic, based on protein and carbohydrate content, biopolymeric carbon and algal contribution to biopolymeric carbon.
