“…Contaminated groundwater is also being used for aquaculture. The accumulation of As in farmed fish and seafood pose a potential threat to human health [ 19 , 21 , 22 , 23 ]. Figure 9 shows fishpond locations in the study area.…”

“…Nowadays, most local residents in southern Taiwan consume tap water processed by the public water company, but a large amount of As-contaminated groundwater is still used for aquaculture. As can accumulate in the tissue of farmed fish and shellfish and recent studies have been carried out to evaluate exposure to As through the consumption of seafood in Taiwan and the related health risk assessment [ 16 , 17 , 18 , 19 , 20 , 21 , 22 , 23 , 24 , 25 ].…”

Chronic arsenic (As) exposure continues to be a public health problem of major concern worldwide, affecting hundreds of millions of people. A long-term groundwater quality survey has revealed that 20% of the groundwater in southern Taiwan’s Pingtung Plain is clearly contaminated with a measured As concentration in excess of the maximum level of 10 µg/L recommended by the World Health Organization. The situation is further complicated by the fact that more than half of the inhabitants in this area continue to use groundwater for drinking. Efforts to assess the health risk associated with the ingestion of As from the contaminated drinking water are required in order to determine the priorities for health risk management. The conventional approach to conducting a human health risk assessment may be insufficient for this purpose, so this study adopts a geostatistical Kriging method to perform a spatial analysis of the health risk associated with ingesting As through drinking groundwater in the Pingtung Plain. The health risk is assessed based on the hazard quotient (HQ) and target cancer risk (TR) established by the U.S. Environmental Protection Agency. The results show that most areas where the HQ exceeds 1 are in the southwestern part of the study area. In addition, the high-population density townships of Daliao, Linyuan, Donggang, Linbian, Jiadong, and Fangliao presently have exceedingly high TR values that are two orders of magnitude higher than the acceptable standard. Thus, the use of groundwater for drinking in these townships should be strictly avoided. A map that delineates areas with high TR values and high population densities is provided. The findings broaden the scope of the spatial analysis of human health risk and provide a basis for improving the decision-making process.

“…A moderate cancer risk (TR˂10 −3 ) was detected in this study for the exposed population, as the TRs for all species were above the risk threshold. The risk associated with the carcinogenic effects of the target TE is expressed as the excess probability of contracting cancer over a lifetime of 70 years (Liang et al, 2011). Over long periods, continued consumption of these fish may represent a potential risk to the health of consumers.…”

Among all available species, fish are a powerful model for risk-benefit assessments to study the effects of contaminants on human health. Gilthead seabream (Sparus aurata, Linnaeus 1758) and european seabass (Dicentrarchus labrax, Linnaeus 1758) are two species of great economic importance, representing very large production volumes in the Mediterranean. The objective of this study is (1) to analyze the concentrations of Trace Elements (TE) between wild and cultured seabream and seabass specimens, (2) to compare the determined concentrations with other studies, and (3) to increase the data about the potential risks to human health. Our results point to significant intra- and interspecies-specific differences between wild and cultured fish for several trace elements. Several strong and moderate inter-elemental correlations in fish muscle were observed through correlation analysis. In our study, the mean levels of trace elements were still below the standard safety values for fish intended for human consumption. The same results were reached for all the parameters analyzed (international legal limits, estimated weekly intake, provisional tolerable weekly intake, target hazard quotient, target cancer risk), with trace element levels in fish below those that could pose a risk to human health. Consequently, these fish can be considered safe for human consumption. A better understanding of the levels of trace elements in fish would also better inform consumers about the potential risks of exposure to contaminants.

“…Contamination of aquatic environment by trace metals have been intensively studied in recent years, due to the fact that metals are persistent, toxic, tend to bioaccumulate, and that they induce a risk for humans and ecosystems (Liang et al, 2011;Lenoble et al, 2013). The main reason for this is the increasing complex mixtures of chemicals discharged to the coastal zone from non-point sources, especially in developing countries.…”
