Ecological risk assessment of heavy metal contamination in mangrove forest sediment of Gulf of Khambhat region, West Coast of India

Abstract

Mangrove forests are in severe threat from heavy metals pollution stimulated by the several human activities connected with hasty industrialization and urbanization. Heavy metals contamination of mangrove ecosystems has caused serious concern worldwide. The objective of the present research is to identify the heavy metal pollution in the mangrove forest sediments of the Gulf of Khambhat, Gujarat, India. The samples were collected from the 12 selected sites of the GoK and investigated for Pb, Cu, Cd, Cr, Ni, As, Co, Mn, Zn, and Hg using Inductively Coupled Plasma Mass Spectrometry. The abundance of heavy metals concentration in the sediment were found in the decreasing order of Mn > Zn > Cr > Ni > Cu

Assessment of trace element accumulation in surface sediment of Sepang Besar river, Malaysia

“…Based on Igeo value, it can be concluded that the studied area enriched with As, Cd, Mo, and Hg. The presence of various metals in sediment may result from the interaction of elevated particulate matter with relatively unpolluted sediments (Singh et al 2020).…”

Analysis and Evaluation of Heavy Metal Pollution in Kosasthalaiyar River near Ennore Creek Using Geo Statistical Approach

“…As a result, contaminants of Hm's with high concentrations are continuously discharged into the river and marine aquatic systems (Li et al 2022). Sediment analysis plays an essential role in determining the concentration of metals in many aquatic ecosystems, surface integration of dissolved Hm's, spatial distribution, sedimentation, behaviors of Hm's and re-suspension, as well as determining the patterns of pollution in ecosystems (Singh et al 2020;Li et al 2022).…”

“…Many contaminants, along with significant metals, can cause biological hazards or sub-lethal effects to aquatic organisms due to toxicity, and the behavior of Hm's is still not fully understood (Chandrasekaran et al 2015;Huang et al 2020;Singh et al 2020;Iordache et al 2022). The solubility, distribution, and kinetic effect of Hm's in sediments depend on the sequence of physical and chemical properties such as seasonal variations, sediment texture, pH, organic matter, Eh, DO, redox potential, chelating agents, etc.…”
