“…The average level of Zn was higher than those from the North Atlantic, North Pacific, Arabian Gulf (Saudi Arabia and Bahrain), and Gulf of Aqaba [15,16,[45][46][47][48][49]. The Ni average value reported in this study is above the values from the Arabian Gulf (Bahrain and Saudi Arabia) and the Gulf of Aqaba [16,46,48], whereas it is lower than those from the Arabian Gulf and the Red Sea coast [17,[50][51][52]. Notably, the Co and Cr levels are higher than the Gulf of Aqaba and the Red Sea values reported from Egypt [17,53,54].…”

High levels of potentially toxic elements (PTEs) in water bodies negatively affect the biota of aquatic ecosystems and surrounding environments. A risk assessment investigation of the levels and distribution of PTEs in the seawater of the Jazan coastal area, southwest Saudi Arabia, was conducted. Thirty-two surface seawater samples were collected, and contamination (Cd) and heavy metal pollution (HPI) indices, as well as multivariate statistics, were applied. The average PTE levels (µg/L), in descending order of magnitude, were Cu (2.56), Pb (2.27), Ni (1.30), Cr (1.28), Zn (1.04), Sb (0.36), Co (0.22), and Cd (0.06). A fluctuating pattern without a fixed direction was detected in the spatial distribution of these metals, with increased pollution being linked to high metal levels as shown by some samples. The HPI indicated low pollution in 50% of the samples and medium pollution in the remaining 50%, whereas the Cd indicated low contamination with PTEs. The absence of significant correlations between pairs of metals indicated different sources of metal pollution. Lithogenic sources are implicated in the supply of Co, Ni, Pb, and Sb, whereas Cr was mainly derived from an anthropogenic source, and combined lithogenic and anthropogenic sources are believed to have contributed Cu and Zn to the area. It is proposed that urbanization, agriculture, and industry are among the potential anthropogenic sources of pollutants on the Jazan coastline. Soils generated on the undifferentiated Quaternary rocks along the investigated area are the main lithogenic sources.

“…In relation to Cd, samples 2 and 4 in the northern region of the research area exhibited the greatest and lowest concentrations (1.020 and 0.100 μg/L, respectively). The observed rise in HM values in certain individual samples can be ascribed to the composition of the mud and fine sediment present at these locations, which possess the capacity to retain HMs and then release them into the water column [42]. The average levels of HMs in Table 2 were less than the maximum admissible concentration [43].…”

Seawater contamination is a global challenge due to its hazardous effects on marine organisms and human health. Twenty-three surface seawater samples were collected from Al Lith intertidal area along the Saudi Red Sea coast to evaluate the ecological risks and document the potential sources of Cr, Cd, Fe, Zn, and Pb. Contamination factor (CF), contamination degree (Cd), water quality index (WQI), and heavy metal pollution index (HPI), as well as multivariate tools were applied. The averages of HMs (μg/L) had the following order: Zn (6.616) &gt; Pb (0.284) &gt; Cd and Cr (0.268) &gt; Fe (0.197). Results of CF showed moderate contamination of seawater with Cd and low contamination for Cr, Fe, Zn, and Pb. However, 26.09% of the samples showed considerable contamination for Cd. Average Cd values revealed low contamination for HMs, while 17.39% of the samples showed moderate contamination. HPI average values indicated medium pollution for Al Lith seawater, meanwhile 13 samples reported high pollution. The higher HPI values were reported in samples characterized by higher concentration of HMs, particularly Cd and Zn. Correlation matrix and principal component analysis suggested anthropogenic sources for Pb and Zn, mostly from industrial and agricultural effluents, landfilling and domestic wastewaters, apart from their natural sources.
