Monitoring programme on cadmium, lead and mercury in fish and seafood from Valencia, Spain: levels and estimated weekly intake.
The study was carried out to determine the current levels of mercury, cadmium, and lead in fish and seafood from the market of Comunitat Valenciana, Spain. Levels of total mercury ranged from 0.02 to 3.15 mg kg⁻¹ w.w. (average = 0.073 mg kg⁻¹ w.w.). Cadmium concentrations ranged from 0.003 to 0.66 mg kg⁻¹ w.w. (average = 0.27 mg kg⁻¹ w.w.) for seafood, and between 0.003 and 0.71 mg kg⁻¹ w.w. (average = 0.01 mg kg⁻¹ w.w.) for marine fish. Concerning lead, concentrations from 0.02 to 0.36 mg kg⁻¹ w.w (average = 0.04 mg kg⁻¹ w.w.) were found in fish, and from 0.02 to 1.02 mg kg⁻¹ w.w. in seafood (average = 0.147 mg kg⁻¹ w.w.). The levels found were, in general, lower than maximum levels propos…
Biomonitoring of mercury in hair of children living in the Valencian Region (Spain). Exposure and risk assessment.
Abstract In this study, we assessed total mercury levels in hair specimens of 661 children, aged 6 to 11, participating in the BIOVAL programme, a human biomonitoring study carried out by the Health Department of the Regional Government of Valencia (Spain). The reference value (95th percentile) determined for this population, within this programme, was 3.25 μg g−1. Hg concentrations ranged between 0.03 μg g−1 and 8.71 μg g−1, with a geometric mean of 0.79 (CI 95%: 0.73–0.85) μg g−1. This mean value was five times higher than the average levels found in children of 17 other European countries (0.145 μg g−1). About 13% of children had hair mercury levels above the FAO/WHO JECFA guideline of 2…
Biomonitoring of mercury in hair of breastfeeding mothers living in the Valencian Region (Spain). Levels and predictors of exposure
This study focused on the evaluation of the levels of total mercury in hair among 120 breastfeeding mothers aged 20 to 45-. The concentrations of Hg ranged from 0.07 to 6.87 mu g/g with a geometric mean (GM) of 1.22 mu g/g. This GM is six times higher than the average internal exposure of mothers from other 17 European countries (0.225 mu g/g). Near 70% of mothers presented levels of Hg above the USA EPA internal exposure guideline of 1 mu g/g, and 27% exceeded the EFSA health-based guidance value of 1.9 mu g/g. The multivariate regression analysis revealed that age, smoking and fish consumption (sword fish, small fat fish, small lean fish) were the major predictors of mercury in hair. (C) …
