“…Human health risk assessment considers three different exposure pathways such as ingestion, inhalation and dermal absorption. In our study, we have focused on dermal absorption because that is the most probable mode that can affect humans in the estuarine environment of the study area (Kim et al 2004 ; Kumar et al 2020 ). Health risk by ingestion or inhalation is minimal because estuarine water is brackish and not potable.…”

Trace metals act as a limiting nutrient and prerequisite for primary productivity in marine environments. The distribution of metals in dissolved phase along the salinity gradients of Swarna, Sharavati and Kali estuaries in southwestern India, during post and pre-monsoon seasons, were studied. We have investigated the behaviour of trace metals in the estuarine environment and their extent of impact on human health and ecosystem. The study revealed, non-conservative behaviour of dissolved Mn, Fe, Ni, Cd and Co in the estuaries. Whereas Cu behaved non-conservatively in post-monsoon and conservatively in pre-monsoon seasons. Risk assessment studies revealed that higher chronic daily intake (CDI) in humans, through dermal pathway, in Swarna and Sharavati estuaries during post-monsoon, whereas it was during pre-monsoon season in the Kali estuary. Hazard Index values for the studied metals in adults and children are below risk thresholds, though children are more prone to health risk through the dermal pathway.

“…Ingestion, inhalation, and dermal absorption are the three main ways that humans may be exposed to heavy metals. When it comes to the health of individuals who participate in water-related activities, skin exposure to contaminated saltwater is more dangerous than ingesting or inhalation [53][54][55]. In the current study, carcinogenic and noncarcinogenic risk factors were used to evaluate the health hazards associated with heavy metal exposure for men, women, and children [56; 8].…”

Trace metals (Li, B, Na, Mg, Al, K, Ca, Ti, Cr, Mn, Fe, Co, Ni, Cu, Zn, Ga, Se, Sr, Ag, Cd, In, Ba, Hg, Pb, Bi) in surface sediments of the Nile Delta coastal area between Western Harbor and Bardaweel Lagoon were evaluated. The ecological risk assessment was evaluated by Contamination degree (Cd), Geoaccumulation Factor (Igeo), Enrichment Factor (EF), Contamination Factor (CF), Hazard Quotient (HQ) and Pollution Load Index (PLI). The EF values are in the sequence: Cr > Pb > Ni > Zn > Cu > Mn. The studied locations were unpolluted with Cr, Cu, Mn, Ni, Pb, and Zn (Igeo ≤0) and the Cd (> 1.5). Significant correlations were reported between the concentrations of Mn, Fe, Cr, Co and Ni suggesting similar sources. The HQ indicate low values for children and 3–4 > adult values. Using principal component analysis (PCA), the sources of heavy metals were categorized.

“…As a result, a comprehensive reflection of the potential of HMs' impact on the ecological environment was provided, which made it suitable for evaluating the pollution of HMs in a wide range of area. According to the literature [117,133,134], the toxic factors of Hg, Cd, As, Cu, Pb, Ni, Cr and Zn are 40, 30, 10, 5, 5, 5, 2 and 1, respectively.…”

This paper reviews research on phytoremediation (2002–2021), particularly for the estimation of plant efficiency and soil pollution indices, examining the extraction of metals from soil and plants growing under both artificial (spiked with specific metal) and natural conditions. From the analysis of >200 published experimental results, it was found that contamination factor and geo-accumulation index as well as translocation and bioconcentration factors are the most important soil pollution and plant efficiency metrices, respectively, which are gaining importance to assess the level of metal pollution and its transfer from soil to plant to find a better metal clean-up strategy for phytoremediation. To access the metal concentration, it was found that the most widely accepted extractants to dissolve and extract the metals from the soil and plant were HNO3 and HClO4 (mainly in 5:1; v/v or 4:1; v/v), which are used both in natural and artificial metal contamination studies. Moreover, plants such as Pteris vittata, Monochoria korsakowi, Lolium perenne, Festuca rubra, Poa pratensis, Ricinus communis, and Siegesbeckia orientalis can act as hyperaccumulators under both natural and artificial experiments and can be directly implemented into the fields without checking their further efficiency in phytoremediation.
