“…Heavy metals enter marine environments through a variety of natural and anthropogenic sources. Heavy metals that enter seawater can interact with suspended particles via adsorption, complexation, and precipitation before being transferred to sediments and enriched ( Liu et al, 2019 ). Therefore, heavy metal pollution in sediments is an important environmental quality indicator, indicating pollution status and guiding ecological risk assessment ( Wang et al, 2018 ).…”

“…Generally, Pb and Cd were the main contributors to the potential ecological risk in the RS. Several studies have suggested that mining activities generate Cd contamination which can seriously threaten the growth of marine life and human health due to its intense biotoxicity and high bioaccumulation potential (Liu et al, 2019;.…”

A comprehensive study was conducted to explore the concentration and distribution of heavy metals in farm soils and river sediments around a gold mining area in Fiji with particular emphasis on ecological and human health risks. Representative samples were acquired from farm sites in Matanagata Village and the Nasivi river, both situated around the Vatukoula gold mine limited (VGML), the largest operational gold mine in Fiji. Following aqua regia digestion and analysis by AAS, the average soil concentrations for Cu (110.4 mg kg–1), Cr (136.2 mg kg–1) and Cd (1.7 mg kg–1), and sediment concentrations for Pb (69.31 mg kg–1), Cd (1.82 mg kg–1), Cu (88.95 mg kg–1) and Cr (143.12 mg kg–1) were found to exceed the recommended guideline values. Based on the geo–accumulation index (Igeo) and enrichments factor (EF), the farm soils were moderately contaminated with Cd while the and sediments showed moderate to significant contamination with Pb, Ni and Cr. Ecological risk assessment confirmed moderate to considerable ecological risk in the metal–contaminated samples, with Cd and Pb generally presenting greater risk compared to other metals. Multivariate analyses including principal component analysis pointed to gold mining activities as a potential source for heavy metals in the area. Furthermore, human health risk assessment (HRA) indicated that while adults faced no significant carcinogenic or non–carcinogenic risks from metal exposure (HI < 1), children were at more risk from Co, Mn, Cr and Fe exposure, as well as potential carcinogenic risk from Cd (ILCR = 1.46E–04).
