“…The Hg contents of the collected fish samples are showed in Figure 2. As expected, the fresh and frozen albacore presented the highest concentration of -1 g -1 ); coincidently with similar studies carried out by (Yusa et al, 2017). These samples presented levels higher than limits established for Chilean Ministry of Health, in according with actual regulation established for maximum mercury contents in fish samples (0.5 mg kg -1 and 1.0 mg kg -1 for non-predators and predators, respectively) (Minsal, 2018).…”

In the present study, we assessed mercury exposure of residents of different sites of Valparaiso Region (Chile) due to fish consumption and atmospheric contamination from coal-burning power plant and copper smelter. Total mercury concentration was determined in 199 hair samples and in 14 species of marine fish, purchased in the supermarket or collected in the studied fishing villages-1 in human hair samples and from 0.04 to 3.-1 in fish samples. Importantly, hair mercury concentration was significantly higher in the case of population exposed to mercury exclusively by fish consumption (e.g. Quintay and Zapallar), in comparison to the residents exposed to industrial emissions and fish consumption (e.g. Puchuncavi, Las Ventanas, Quintero). Finally, high mercury concentrations were observed in fish types commonly consumed by the residents of the fishing villages, evidencing human exposure to mercury through fish consumption.

“…However, our results were higher than those found in women in Korea, Australia, and Saudi Arabia (see Table 6). It is also appropriate to mention that, in a previous study, mothers in the same region presented a GM of total Hg in hair that was 6 times higher than the average internal exposure of mothers from 17 other European countries, and nearly 70% of mothers presented levels of Hg above US Environmental Protection Agency internal exposure guidelines, with 27% exceeding the European Food Safety Authority health‐based guidance value (Yusà et al 2017). Hair Hg levels are an excellent biomarker for MeHg, whereas Hg in the urine mainly reflects exposure to inorganic Hg.…”

“…In this regard, Hg is one of the most important toxic metals. Although exposure to MeHg, the toxic form, whose main source is fish consumption, is evaluated using Hg concentrations in blood and hair (Vieira et al 2013; Yusà et al 2017), urinary Hg is a biomarker of recent exposure to inorganic species, which are less toxic. According to Castaño et al (2012), the main predictor of urinary levels of Hg was the presence of dental amalgams.…”

“…Arsenic is excreted in the urine in several chemical forms, with a half‐time of a few hours to 2 d. These chemical forms include inorganic species (arsenous and arsenic acids) and organic species, such as arsenobetaine (AsB), dimethylarsinic acid (DMA), and monomethylarsonic acid (MMA; European Food Safety Authority 2009). Urinary speciated arsenic level, established as the sum of i As, DMA, and MMA, is commonly employed as a biomarker of short‐term exposure to i As (Yusà et al 2017).…”

The present study analyzed the exposure and risk assessment of 4 toxic (Hg, Cd, As, Tl) and 2 essential (Se, Mo) elements in 119 Spanish women of reproductive age. The focus was on the elements for which risk‐based benchmark, biomonitoring equivalents, or health‐related human biomonitoring values have already been established. All elements presented frequencies of detection of 100% (greater than the limit of detection), except for Cd (99%). The 95th percentile concentrations were, for the toxic metals, 358.37 µg/L (total As), 1.10 µg/L (Cd), 0.41 µg/L (Tl), and 3.03 µg/L (total Hg) and, for the essential elements, 68.95 µg/L (total Se) and 154.67 (Mo). We examined sociodemographic factors and dietary habits of women as predictors of urinary metal concentrations. Arsenic was positively associated with fish, shellfish, and canned fish consumption, whereas Mo was found to be associated with the consumption of cereals and pastry products. Maternal urine levels of As were negatively correlated with gestational age. In a risk‐assessment context, hazard quotients (HQs) using the 95th percentile ranged from 0.08 (Tl) to 15.1 (urinary speciated As), with Cd presenting an HQ of 1.1 (95th percentile). None of the essential metals presented concentrations higher than their upper intake level; however, 3% of the mothers showed lower levels of Se than the estimated average requirement (EAR) biomonitoring equivalent, and 20% of the mothers were found to have lower levels of Mo than the EAR biomonitoring equivalent, suggesting a nutritionally inadequate diet.

Today, mercury is a matter of concern for health and environmental authorities across western countries, and legislation has been passed and programs have been implemented for its total elimination from human activity. But this was not always the case: mercury and its compounds have been highly appreciated and used since remote times all over the world with very diverse purposes ranging from decorative, medicinal, metallurgical and symbolic. In particular, cinnabar (HgS, mercury sulfide), a mineral of an intense red color, has been considered in many cultures as an exotic raw material, highly valued and associated with the elites and sacred practice. In this paper, we examine one such case, set almost 5000 years ago, in Copper Age Iberia, by investigating mercury exposure through human bone. The study presented here includes a total of 170 samples from 70 different human individuals and 22 animals (plus one soil sample) from the Copper Age mega-site of Valencina, south-western Spain. It is the largest ever single-site study of exposure to mercury based on human bone in combination with cinnabar use. Abnormally high values are recorded in some individuals dating between 2900 and 2650 BC, especially in those buried in remarkable tombs belonging to the social elite of this period, but high levels of mercury are also recorded in the rest of the population. Three lines of interpretation are used to explain these results, including the manipulation of cinnabar (grinding it into powder, mixing it with other substances, using it for the decoration of objects, buildings and the human body), its direct consumption through ingestion or inhalation by a ‘special’ social group and the contribution of environmental factors. Based on the currently available evidence, which is carefully reviewed, Valencina represents the most intense and prolonged case of exposure to mercury recorded in human history, which makes it an important site to assess the long and complex history of use of this substance.
