“…The results are shown in Table 3, which indicates that the developed electrochemical sensing system has good reliability, and can be used for field determination and analysis. Compared with the Se (IV) reported from the world's coastal areas, the average Se (IV) concentrations in the three regions of Yantai Sishili Bay, Shengshan Island, and Zhelin Bay in this study were higher than those in San Francisco Bay (0.01 µg/L) [44], the North Pacific Ocean (0.01 µg/L) [45], the South China Sea (0.04 µg/L) [46], the Atlantic Ocean (0.03 µg/L) [5], and the Mediterranean Sea (0.13 µg/L) [47], but lower than the Arabian Gulf (48.15 µg/L) [48]. Since the sampling sites of Yantai Sishili Bay, Shengshan Island, and Zhelin Bay are located in harbors and near aquaculture areas under the drastic influence of man-made activities in the surrounding area, the concentration is high, but the concentration of Fan is still within the permissible threshold.…”

A portable electrochemical system based on rGO/AuNPs/Nafion was constructed for selenium (IV) field determination in coastal seawater of the North Yellow Sea, East China Sea and South China Sea. This system demonstrated a low determination limit (0.03 μg/L), a wide linear range of concentration (0.1–30 μg/L), exceptional reproducibility and repeatability, and excellent selectivity. Each individual, entire test could be accomplished within 8 min. In Yantai Sishili Bay, the Se (IV) concentrations ranged from 0.16–3.59 μg/L (average 1.43 μg/L). In Shengshan Island, the Se (IV) concentrations ranged from 0.20–5.18 μg/L (average 2.06 μg/L). In Zhelin Bay, the Se (IV) concentrations ranged from 0.87–4.87 μg/L (average 3.13 μg/L). The average concentrations of Se (IV) in surface seawater showcased an increasing trend from the north to the south of China, suggesting Zhelin Bay > Shengshan Island > Sishili Bay. The system develops a new, competitive method for water quality assessment, and contributes to the accurate study of the biogeochemical cycles of selenium.

“…The potential carcinogenic or non-carcinogenic effects of contaminants on humans are usually considered during risk assessments. Unfortunately, sufficient research is not evaluating the combination of heavy metals' ecological risk and biochemical composition from fish in Bardawil Lake (El Sawy et al, 2023). In construction, physical and chemical parameters for Bardawil Lake locations (water quality) were assessed or investigated area as previous study (Zaghloul et al, 2023).…”

Bardawil Lake is a unique aquatic ecosystem that provides a habitat for various fish and other aquatic organisms. This study aimed to analyze the quality of fish species to make sure this lake, like the rest of the other Egyptian lakes, suffers from the deterioration of fish product quality due to the accumulation of some heavy metals (Cd, Pb, Cu, and Zn) in various tissues from fish species that were caught from this lake. 35 fish samples were caught during spring, 2018; from seven different species: Mugil cephalus, Liza auratus, Sparus aurata, Dicentrarchus labrax, Siganus rivulatus, Anguilla angilla, and Solae Solea. The Association of Official Analytical Chemists methods using a spectrophotometer determined the biochemical composition. In contrast, atomic absorption spectrometry was employed to determine the heavy metals expressed by µg/g wet weight. Results exposed that the accumulation of essential micronutrient (Cu, Zn) content was higher than toxic elements (Cd & Pb) in muscles to Zn > Cu > Pb > Cd. Muscles < gills < liver in all metals except Pb muscles < liver < gills. The metals studied in the muscles were lower than those set by the WHO, and the EU standard. The carcinogenic risk with lower allowable limits of 1x10-6 to 1x10-4 in both normal and high consumption groups; target and total target hazard quotients (THQ & HI) in muscles were <1. The biochemical composition level was highest in the liver, except for protein, which was highest in muscle for all fish species. There is no evidence of harmful contaminants in the muscular tissue of the fish sampled from Bardawil Lake. However, customers should be aware that health concerns may be associated with eating too much fish
