“…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).…”

“…Another study from Turkey reported mean hair mercury levels of 0.14-3.28 ppm (Dogan, 1997). Studies from other countries report results between 0.005 and 22.5 ppm for hair mercury levels (Al-Majed and Preston, 2000;Björnberg et al, 2005;Carta et al, 2003;Elhamri et al, 2007;Frery et al, 2001;Harada et al, 1998;Iwasaki et al, 2003;Johnson et al, 2004;Knobeloch et al, 2005;Kehrig et al, 1998;Lebel et al, 1998;Legrand et al, 2005;Lindberg et al, 2004;McDowell et al, 2004;Papu-Zamxaka et al, 2010;Pinherio et al, 2005;Yokoo et al, 2003).…”

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

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.

“…This may be explained by the fact that these populations are characterized by higher dietary fish consumption. At the same time, compared to communities living in close proximity to the Mediterranean coast, Lebanese young adults had much lower mean THHg compared to that of Tunisian young adults living in Sfax (mean = 6.2-6.7 μg/g) (Mezghani-Chaari et al 2011), Moroccans (GM = 1.79 μg/g) (Elhamri et al 2007), and…”

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.
