<abstract xmlns="http://www.w3.org/1999/xhtml"> The mercury content in hairs was determined in the framework of the European funded projects COPHES and DEMOCOPHES to test the feasibility of an EU-HBM (Human Biomonitoring) approach generating comparable data. The aim of the Slovak participation in DEMOCOPHES was to obtain and contribute the Slovak data to the harmonization of Human Biomonitoring. Pre-analytical and analytical phase for mercury in hair measurements and activities developed for the harmonization analysis within COPHES/ DEMOCOPHES projects were conducted under a strict quality assurance program (QA/QC). Total mercury in hair was determined by thermal decomposition-gold amalgamation atomic absorption spectroscopy (AMA- 254 Advanced Mercury Analyzer.) Two interlaboratory comparison investigations (ICIs) and two external quality assessment schemes (EQUAS) were conducted before the beginning of the COPHES/DEMOCOPHES projects. The laboratory successfully completed both ICIs and EQUAS schemes and was allowed to analyze all DEMOCOPHES samples of the Slovak Republic. In summary, 129 mother-child pairs were recruited to pilot study of DEMOCOPHES in Slovakia from two different locations representing urban and rural environment.
