“…However, with the rising pollution of the fluvial and coastal ecosystems, the current scenario alarms humanity and marine life (Bingöl et al, 2013 ; Fernandes et al, 2008 ; Tavakoly Sany et al, 2014 ; Zahra et al, 2014 ). Due to their non-degradability and ability to bioaccumulate in the food chain, metal pollution has become a global problem and gaining the prime attention of the decision-makers (Bastakoti et al, 2019 ; Ergül et al, 2013 ; Prajith et al, 2016 ; Xavier et al, 2020 ). Hence investigation of biogeochemistry of rivers and estuaries provides insights to the trace metal toxicity and its bioavailability for the well-being of aquatic biota.…”

“…On the other hand, contaminated sediments will not remain at the bottom perpetually; varying hydrodynamic conditions and geochemical processes lead to resuspension of contaminants between sediments and water column, which can adversely affect the aquatic life (Atkinson et al, 2007;Hu et al, 2013). There are many factors such as grain size (Fernandes & Nayak, 2016;Mokwe-Ozonzeadi et al, 2019;Nasnodkar & Nayak, 2015), organic matter (Ghosh et al, 2016), mangroves (Bastakoti et al, 2019;Xavier et al, 2020), and hydrodynamic conditions (Dessai et al, 2009;Liu et al, 2019) in regulating the deposition and distribution of trace metals. Also, sediments are significant in archiving past environmental and climate-related changes (Ahmed et al, 2018;Alharbi et al, 2019); thus, it is possible to predict the past contamination vis-à-vis the present situation.…”

The present study aims to assess the extent of trace metal pollution in the sediments of Sita-Swarna estuary, west coast of India, and investigate their possible ecological risk on the aquatic environment. The sediment cores were analyzed for sand, silt, clay, organic carbon, and trace metals (Al, Fe, Mn, As, Cd, Co, Zn, Pb, Ni, Cr, and Cu) at 2-cm intervals. The study revealed that sediments have deposited in relatively violent to very violent hydrodynamic energy conditions. Factor analysis indicated that the metal distribution is mainly controlled by Fe–Mn oxyhydroxides and organic carbon. Further, the geochemical approach, pollution indices, and statistical evaluation revealed moderate pollution in the catchment. From an ecotoxicological perspective, the estimated risk index (RI) value was found to less than 150, indicating low risk for aquatic life. Thus, this baseline study would help to adopt strategies in pollution control and protect the fragile marine environment.

“…Additionally, many of the ESs provided by mangroves are directly associated with soil processes and soil quality (SQ) [10][11][12]. Accordingly, SQ can be conceptualized as a soil's capacity to perform its functions, such as sustaining its productivity, improving water quality, and providing ESs.…”

Applying the Soil Management Assessment Framework (SMAF) to Assess Mangrove Soil Quality

Soil quality (SQ) refers to its capacity to perform its functions. Thus, the SQ index (SQI) is a potentially useful tool for monitoring soil changes induced by mangrove restoration initiatives. Although the soil management assessment framework (SMAF) is a well-developed tool for SQ assessments in diverse ecosystems, it has never been tested on mangrove soils. In this study, we tested the SMAF to evaluate the shifts in the SQ of mangroves in a reforestation initiative using three- and seven-year plantations, which were compared with degraded and mature mangroves. A minimum dataset, composed of the pH and available P as chemical indicators, bulk density as a physical indicator, and soil organic carbon as a biological indicator, was used to calculate the SQI. The SMAF scores facilitated the monitoring of improvement in the mangrove SQ with vegetation development, mainly driven by physical and biological indicators. The SMAF may be a useful tool for monitoring SQ in mangroves under protection and recovery initiatives. Nevertheless, we suggest the inclusion of additional biological and chemical indicators in the minimum dataset for future studies to better represent specific processes and functions (e.g., microbial redox reactions and contaminant immobilization) that can alter the SQ of mangroves.
