Biomonitoring as a tool for verification of population exposure to environmental toxic compounds and for health risk assessment is since 1994 an integral part of the Czech Environmental Health Monitoring System (MZSO). Since 2006, the Czech Republic, by means of National Institute of Public Health, has been taken part in the PHIME project (Public health impact of long-term, low-level mixed element exposure in susceptible population strata) of the 6th FP of EU. In this project, the levels of lead, cadmium and mercury have been examined in blood of 150 children (79 boys, 71 girls) aged 5-12 years, living in regions with different environmental pollution (Praha, Mníšek pod Brdy, Ostrava and Kašperské Hory). Blood lead levels of children from Kašperské Hory showed increased levels (median 30 μg/l) compared with the children from other regions (medians 25, 25 and 24 μg/l). These data correspond with the Czech Human Biomonitoring results (MZSO) and do not exceed the tolerable limit value of 100 μg/l. Blood cadmium levels were low and oscilated around the detection limit of 0.2 μg/l. Blood mercury levels (medians) ranged from 0.32 to 0.42 μg/l and are comparable with the MZSO results (children of similar age) from the year 2006 (0.40 μg/l) as well as 2008 (0.30 μg/l). The results did not indicate the increased exposure of the monitored Czech child population to selected toxic metals. Blood lead levels reflect a gradual downward trend. The obtained data complete the existing time-related trends and are important for international comparison.
