“…In comparison with historical data [20], the contents of Cu and Cd have increased markedly. Except for the much higher contents of Hg and As, the heavy metal contents determined in the present study were basically consistent with those of the southern Gulf of China [13,17,[27][28][29]. is comparison indicates that heavy metal content of the seawater of Jiaozhou Bay was the highest among all documented bays [30].…”

“…Compared with historical data [20], Pb contents have increased markedly, while other heavy metal contents have remained unchanged. In this paper, the heavy metal contents in sediments were lower than those of other marine areas and bays in China [10,17,28,36,37], except for Pb content, which was much higher than in all other locations.…”

“…Accumulation may be magnified via the food chain, thereby threatening the marine ecosystem and human health [14][15][16]. Zhao et al [17] reported that some seafood from Xiangshan Bay might pose noncarcinogenic risks to both adults and children. Although consumption of most common types of seafood from Xiamen markets does not pose a noncarcinogenic risk, some types, such as yellowfin bream (Sparus latus), oyster, and the Red alga (nori; Porphyra tenera), could form a carcinogenic risk [18].…”

Coastal waters are polluted by heavy metals to varying degrees, posing potential risks to marine ecology and human health. In May 2006, the pollution levels, sources, and ecological risks of heavy metals (Cu, Pb, Zn, Cd, Hg, and As) in seawater, surface sediments, and living organisms were studied in Jiuzhen Bay in Fujian, China. This study identified Hg (0.26–0.72 µg/L) and As (20.3–31.5 µg/L) pollution in the seawater of Jiuzhen Bay. In sediments, heavy Pb pollution (946 µg/g dw) was only detected at one station at a level posing very serious potential risk, while Hg pollution (0.052–0.087 µg/g dw) was observed at three stations at a level posing serious potential risk. No heavy metal pollution was detected in sediments at other stations. The concentrations of five heavy metals (Cu, Zn, As, Cd, and Pb) exceeded the corresponding National Quality Standards for oysters, indicating heavy pollution, based on an ecological risk assessment. In clams, two heavy metals (Pb and As) exceeded the standards, indicating light pollution, based on an ecological risk assessment. No heavy metal pollution was found in fish or shrimps. The heavy metals in the seawater and sediments of Jiuzhen Bay are mainly derived from the river discharges of Luxi and Wujiang Rivers although sewage discharge along the coast of Jiuzhen Bay is another source of heavy metal pollution at some stations. Given the pollution of Pb, Hg, and As in seawater and sediments at some stations within the bay, the potential risks of Pb, Hg, and As in living organisms to both the marine ecology and human health deserve increased attention.

“…In the comparison of Cu concentrations in different coastal areas (Table 3), the Vigo estuary has lower levels than the highly polluted areas of Xiangshan Bay (China; [39]) and the Yellow Sea (South Korea; [40]) and shows occasional higher copper levels than the Laoshan Bay (China; [41]) and the Gulf of Cádiz (South Spain; [42]).

Limited attention has been directed toward the effects of maritime traffic on heavy metals and metalloids in seawater. Water samples were collected from the estuary of Vigo Ría in the summer of 2018. The chemical distribution of ten dissolved trace metals and metalloids (Cr, Mn, Fe, Cu, Zn, As, Se, Cd, Hg, and Pb) in water was determined from north to south (where the biggest city in the region is) and from east to west (where the maritime traffic is higher). Metal concentration in waters showed that most metals were below recommended water quality criteria by the United States Environmental Protection Agency (EPA). One of the samples had a Cu concentration higher at the entrance of the Vigo estuary, where maritime traffic is very important. Cu and Zn concentrations were highly correlated between them, showing a similar pollution origin, probably due to anti-fouling paints. Mn and Fe are elements influenced by river sources.

“…The

and RI values are classified into five and four degrees of ecological risk, respectively. The classifications are as follows: (1)

< 40, low ecological risk; 40 <

<80, moderate ecological risk; 80<

<160, considerable ecological risk; 160<

<320, very high ecological risk;

≥ 320, disastrous ecological risk; (2) RI < 150, low ecological risk; 150 < RI < 300, moderate ecological risk; 300 < RI < 600, considerable ecological risk; RI ≥ 600, very high ecological risk [ 22 ].…”

Heavy metals are extremely harmful materials to marine ecosystems and human health. To determine the anthropogenic contributions and ecological risks in Weitou Bay, China, the spatiotemporal variations in the concentrations of heavy metals in surface sediment were investigated during spring 2008 and 2017. The results indicated that high concentrations of pollutants were generally located near the river mouths and along the coast of industrial areas. Principal component analysis indicated that heavy metal contents were mainly affected by industrial waste drainage, urban development, natural weathering and erosion, and interactions between organic matter and sulfides. The potential ecological risk assessment demonstrated that, in 2008, 82% of the sampling sites were at low risk, while 18% were at moderate risk. The situation had deteriorated slightly by 2017, with 73%, 18%, and 9% of stations in Waytou Bay at low, moderate, and very high risk, respectively. Cd was the most harmful metal, followed by Hg. These two elements accounted for more than 80% of the potential ecological risk index (RI) value. The present work analyzed the source of heavy metals, identified the major pollution elements and high risk areas, and provides guidance for pollution control and ecological restoration in Weitou Bay.
