“…The estimated average daily intake, EDI (mg/kg body weight/day), represented an estimate of the daily exposure dose of pollutants/heavy metals that consumers might be exposed to through their diets. The EDI was calculated using the formula = C × CR × IR/BW [ 41 , 42 ], Where C is the concentration of heavy metal, CR is the conversion factor (To convert the concentration of sample from dry weight to fresh weight values, a conversion factor of 0.2 was used based on the moisture content of fresh leaf (80%); IR is the average daily consumption which was considered as 0.3 kg/person/day [ 43 ], 0.17 kg/person/day [ 44 ] and 0.1 kg/person/day [ 45 ]. BW is the average body weight of consumers, which was estimated as 27 kg for children aged 6–9yrs [ 46 ] and 70.3 kg for adults [ 47 , 48 ].…”

“…China's marine aquaculture production grows from 1.58 million tons in 1989 to 18.76 million 58 tons in 2015. Oysters have become one of the most popular seafood in coastal or even inland regions nowadays, 59 because they are of high nutrients, affordable, and widely farmed (García-Rico and Tejeda-Valenzuela 2020). The 60 oyster aquaculture production from the northern South China Sea took around 36.3% of China's total production of 61 bivalves aquaculture in 2000, 2010, and 2015.…”

Estuarine and coastal ecosystems are often considered vulnerable due to the complex biogeochemical processes and the human disturbances through a variety of pollution. Among environmental contaminants, heavy metals in estuarine and coastal ecosystems have been of increasing concern in environmental conservation. Long-term exposure to heavy metal contamination, mainly through food and water, could be harmful to human health. It is therefore critical to understand the quantitative comparisons and interacting effects of different heavy metals in common seafood species, such as oysters. This work studied the long-term spatiotemporal trends and health risk assessment of oyster arsenic (As), cadmium (Cd), copper (Cu), mercury (Hg), lead (Pb) and zinc (Zn) levels in the coastal waters of northern South China Sea. Cultured oysters (Crassostrea rivularis) from 23 estuaries and harbors in the coastal areas of northern South China Sea in 1989–2015 were analyzed for the spatiotemporal trends of the six heavy metal levels. Metal pollution index (MPI), target hazard quotient (THQ) and hazard index (HI) were used for quantifying the exposure of the six heavy metals to human health through oyster consumption. Principal component analysis (PCA) was used for assessing the relative importance of the six metals in oyster heavy metal distribution patterns in the northern South China Sea. Overall, the As, Cd, Cu, Hg, Pb and Zn levels in oysters from the northern South China Sea generally declined from 1989 to 2015, stayed relatively high (MPI = 2.42–3.68) during 1989–2000, gradually decreased since 2000, and slightly increased after 2010. Oyster heavy metal levels were highest in the Pearl River Estuary (MPI = 1.20–5.52), followed by west Guangdong and east Guangdong, Guangxi, and Hainan coastal waters. This pattern is probably because economics and industry around the Pearl River Estuary have been growing faster than the other areas of this work in the recent two decades, and it should be taken as a hotspot for the monitoring of seafood safety in southern China. Principal component analysis indicated that Cu, Zn and Cd were the most important metals in the long-term distributions of oyster heavy metal levels in the northern South China Sea. Health risk assessment suggested that the risk of the six heavy metals exposure through oyster consumption were relatively high during 1989–2005 (THQ = 1.01–5.82), significantly decreased since 2005 (THQ < 1), and slightly increased after 2010.
