“…Our reported mean THHg was also higher than that reported for a community in North East India (mean = 0.28 μg/g) (Masih et al 2016), and for women in Southern Iran (mean = 0.37 μg/g) (Barghi et al 2012). In contrast, the mean THHg found in our studied group was lower than that found in various Asian populations, including Asians living in Chicago (GM = 0.58 μg/g) (Buchanan et al 2015), AsianTaiwanese women (mean = 1.73 μg/g) (Chien et al 2010), and a Japanese population (mean = 2.02 μg/g) (Nakagawa 1995). This may be explained by the fact that these populations are characterized by higher dietary fish consumption.…”

“…The frozen and canned fish, whether locally processed or imported, consisted of tuna, European pilchard, salmon, fish fillet and fish fingers, and others. Fish consumption was determined as the number of servings of each type of fish per week, and daily intake amounts were computed assuming a serving is equivalent to 120 g of fish (Chien et al 2010). Interviewers provided participants with visual aids to help them assess the serving size and to recognize accurately the different types of fish.…”

“…In addition, THHg increased with fish consumption and age in women of childbearing age in the state of Florida (Traynor et al 2013). Similarly, THHg in groups that consume fish were found to be significantly higher than groups that never consumed fish in Northern Taiwan (Chien et al 2010).…”

Mercury (Hg) exposure represents a significant public health concern at a global level. This study aims at assessing Hg exposure and risk among Lebanese young adults based on Hg biomonitoring and seafood intake. A group of 166 young adults were administered a questionnaire to assess Hg exposure and were asked to provide a hair sample. Risk assessment was performed: (1) using the US Environmental Protection Agency Hazard Quotient (HQ) model based on fish intake and previously studied local fish Hg concentrations, and (2) by determining the total hair Hg concentration (THHg) using continuous flow-chemical vapor generation atomic absorption spectrometry. Differences in THHg across demographic and exposure subgroups were tested using t test or ANOVA. Correlations between THHg concentrations, fish consumption, and HQ were determined by computing Pearson's r. Higher THHg correlated with higher consumption of Mediterranean rabbitfish/spinefoots (r = 0.27; p = 0.001) and geographical location (p < 0.001) in the bivariate analysis, and remained significant in the adjusted multivariable linear regression model (geographical location: ß = 0.255, 95%CI 0.121-0.388; rabbitfish/spinefoots consumption: ß = 0.016, 95%CI 0.004-0.027). No significant correlations were found between HQ and THHg. In conclusion, this is the first study examining hair Hg levels and fish consumption in a young adult Lebanese population. Our findings constitute valuable baseline data for a local fish advisory and Hg monitoring.

AbstractBackground:The Danish part of the large European Human biomonitoring pilot project Demonstration of a study to Coordinate and Perform Human biomonitoring on a European Scale (DEMOCOPHES) investigated the urine, hair and blood concentrations of 66 different environmental chemicals in a group of 145 Danish school children aged 6–11 years and their mothers from rural and urban areas in autumn 2011. Some – but not all – results were published; however, the concurrence of the chemicals has not been assessed.Methods:The measured concentrations of polybrominated diphenyl ethers (PBDEs) and glyphosate is assessed to complete the investigation of all 66 chemicals in DEMOCOPHES. The concentrations of PBDEs were measured in plasma samples of 143 mothers and 116 children. Glyphosate was measured in a subsample of 27 urine samples. Previously assessed chemicals were polychlorinated biphenyls (PCBs), and polyfluoroalkyl substances (PFASs) analyzed in blood samples, mercury analyzed in hair, and phthalate metabolites, parabens, phenols, cadmium, paracetamol and cotinine analyzed in urine samples. Differences in concentrations between mothers and children were assessed, and the associations between the concentrations of the different environmental chemicals. investigated by correlation analysis.Results:PBDE47 was found in relatively high levels compared with previous Danish results in both mothers and children, with a significantly higher level in the children compared to their mothers. Glyphosate in concentrations around 1 ng/mL was detected in all 27 samples. The analyzed environmental exposures seem to follow a pattern where chemicals within the same classes are strongly correlated and where children and mothers are exposed to the same chemicals.Conclusion:The correlations between the measured environmental chemicals indicate that a specific exposure pattern may exist, where people who are highly exposed to one class of environmental chemicals also may be highly exposed to certain other classes. As some of the compounds were measured in higher levels in children compared to mothers, increased focus also on the exposure in young children is recommended. For more detailed investigation of specific exposure sources more studies with increased power and detailed questionnaires should be developed.

“…Mean mercury intake through fish consumed calculated for the previous month was higher among fishmongers compared to cleaning company employees. This is compatible with the literature (Al-Majed and Preston, 2000;Barbieri et al, 2009;Björnberg et al, 2005;Cheng et al, 2009;Chien et al, 2010;Diez et al, 2008;Dogan, 1997;Elhamri et al, 2007;Freire et al, 2010;Harada et al, 1998;Johnson et al, 2004;Lebel et al, 1998;Legrand et al, 2005;Lindberg et al, 2004;McDowell et al, 2004;Oliveira et al, 2010;Schoeman et al, 2010;Ü nlü, 1993).…”

Determining mercury levels in anchovy and in individuals with different fish consumption habits, together with their neurological effects

et al. 2014

An increase in enviromental pollution may lead to mercury toxicity of fish origin due to the accumulative nature of methylmercury in fish. The main sources of human exposure to organic mercury compounds are contaminated fish and other seafoods. This descriptive study was planned to determine mercury levels in anchovy and in hair samples from individuals with different fish consumption habits, and to evaluate those individuals in terms of toxic effects. For that purpose, we analyzed 100 anchovies from the Black Sea and 100 anchovies from the Sea of Marmara, and assessed 25 wholesale workers in fish markets and 25 cleaning firm employees from both Ankara and Istanbul. Mercury levels in samples were measured using a cold vapor atomic absorption spectrophotometer. Participants were examined neurologically and mini mental state examination was applied to evaluate their cognitive functions. Mercury levels in fish were found to be below the national and international permitted levels. There was no statistically significant relation between mercury levels and the sea from which fish were caught. Hair mercury levels for all participants were within permitted ranges. However, hair mercury levels in both cities increased significantly with amount and frequency of fish consumption. A significant correlation was determined at correlation analysis between levels of fish consumption and hair mercury levels in the fishmongers and in the entire group (r = 0.32, p = 0.025; r = 0.23, p = 0.023, respectively). Neurological examination results were normal, except for a decrease in deep tendon reflexes in some participants in both cities. There was no correlation between Standardized Mini Mental State Examination results and hair mercury levels. We conclude that establishing a monitoring system for mercury levels in fish and humans will be useful in terms of evaluating potential neurotoxic effects.
