About the Laboratoire national de santé (LNS) and the Service ‘Environmental Hygiene and Human Biological Monitoring’:

The Department Health Protection supports public health and health care for problems caused or aggravated by the environment, including indoor pollution, the working context, and consumer products. We fulfill this mission through servicing including expert advice, education and applied research.

The Department Health Protection hosts two Services:

• The Service “Environmental Hygiene and Human Biological Monitoring” carries out laboratory analyses – chemical and microbiological – in dust, air and surface samples (ISO/IEC 17025 accreditation). In parallel, the Service analyses the concentrations of substances or their metabolites directly in human medical samples, for example blood, urine, hair. The Service measures not only human biomarkers of exposure (ISO 15189 and ISO/IEC 17025 accreditation), but is expanding its portfolio of human biomarkers of effect relevant in the pathways of disease development and progression.

Within PARC, LNS is grant signatory for Luxembourg and key partner in several workpackages related to human biomonitoring and risk assessment for human exposure to chemicals from the indoor and occupational environment. It involves 200 partners from 28 European countries, including national and EU agencies as well as affiliated research organizations.

The Service supports the National Service for Environmental Medicine at the Hospital Center Emile Mayrisch (CHEM) and is in charge of the European science-policy programs and the epidemiological surveys in the general and working population in Luxembourg that include human biological monitoring and/or environmental/occupational exposure assessment.
