- Cadmium exposure in adults across Europe: Results from the HBM4EU Aligned Studies survey 2014-2020Publication . Snoj Tratnik, Janja; Kocman, David; Horvat, Milena; Andersson, Anna-Maria; Juul, Anders; Jacobsen, Eva; Olafsdottir, Kristin; Klanova, Jana; Andryskova, Lenka; Janasik, Beata; Wasowicz, Wojciech; Janev Holcer, Natasa; Namorado, Sónia; Coelho, Inês; Rambaud, Loic; Riou, Margaux; Van Nieuwenhuyse, An; Appenzeller, Brice; Kolossa-Gehring, Marike; Weber, Till; Esteban, Marta; Castano, Argelia; Gilles, Liese; Rodriguez Martin, Laura; Schoeters, Greta; Sepai, Ovnair; Govarts, EvaThe objectives of the study were to estimate the current exposure to cadmium (Cd) in Europe, potential differences between the countries and geographic regions, determinants of exposure and to derive European exposure levels. The basis for this work was provided by the European Human Biomonitoring Initiative (HBM4EU) which established a framework for alignment of national or regional HBM studies. For the purpose of Cd exposure assessment, studies from 9 European countries (Iceland, Denmark, Poland, Czech Republic, Croatia, Portugal, Germany, France, Luxembourg) were included and urine of 20–39 years old adults sampled in the years 2014–2021 (n = 2510). The measurements in urine were quality assured by the HBM4EU quality assurance/quality control scheme, study participants' questionnaire data were post-harmonized. Spatially resolved external data, namely Cd concentrations in soil, agricultural areas, phosphate fertilizer application, traffic density and point source Cd release were collected for the respective statistical territorial unit (NUTS). There were no distinct geographic patterns observed in Cd levels in urine, although the data revealed some differences between the specific study sites. The levels of exposure were otherwise similar between two time periods within the last decade (DEMOCOPHES - 2011–2012 vs. HBM4EU Aligned Studies, 2014–2020). The age-dependent alert values for Cd in urine were exceeded by 16% of the study participants. Exceedances in the different studies and locations ranged from 1.4% up to 42%. The studies with largest extent of exceedance were from France and Poland. Association analysis with individual food consumption data available from participants’ questionnaires showed an important contribution of vegetarian diet to the overall exposure, with 35% higher levels in vegetarians as opposed to non-vegetarians. For comparison, increase in Cd levels due to smoking was 25%. Using NUTS2-level external data, positive associations between HBM data and percentage of cropland and consumption of Cd-containing mineral phosphate fertilizer were revealed, which indicates a significant contribution of mineral phosphate fertilizers to human Cd exposure through diet. In addition to diet, traffic and point source release were identified as significant sources of exposure in the study population. The findings of the study support the recommendation by EFSA to reduce Cd exposure as also the estimated mean dietary exposure of adults in the EU is close or slightly exceeding the tolerable weekly intake. It also indicates that regulations are not protecting the population sufficiently.
- FAIR environmental and health registry (FAIREHR)- supporting the science to policy interface and life science research, development and innovationPublication . Zare Jeddi, Maryam; Galea, Karen S.; Viegas, Susana; Fantke, Peter; Louro, Henriqueta; Theunis, Jan; Govarts, Eva; Denys, Sébastien; Fillol, Clémence; Rambaud, Loïc; Kolossa-Gehring, Marike; Santonen, Tiina; van der Voet, Hilko; Ghosh, Manosij; Costa, Carla; Teixeira, João Paulo; Verhagen, Hans; Duca, Radu-Corneliu; Van Nieuwenhuyse, An; Jones, Kate; Sams, Craig; Sepai, Ovnair; Tranfo, Giovanna; Bakker, Martine; Palmen, Nicole; van Klaveren, Jacob; Scheepers, Paul T. J.; Paini, Alicia; Canova, Cristina; von Goetz, Natalie; Katsonouri, Andromachi; Karakitsios, Spyros; Sarigiannis, Dimosthenis A.; Bessems, Jos; Machera, Kyriaki; Harrad, Stuart; Hopf, Nancy B.The environmental impact on health is an inevitable by-product of human activity. Environmental health sciences is a multidisciplinary field addressing complex issues on how people are exposed to hazardous chemicals that can potentially affect adversely the health of present and future generations. Exposure sciences and environmental epidemiology are becoming increasingly data-driven and their efficiency and effectiveness can significantly improve by implementing the FAIR (findable, accessible, interoperable, reusable) principles for scientific data management and stewardship. This will enable data integration, interoperability and (re)use while also facilitating the use of new and powerful analytical tools such as artificial intelligence and machine learning in the benefit of public health policy, and research, development and innovation (RDI). Early research planning is critical to ensuring data is FAIR at the outset. This entails a well-informed and planned strategy concerning the identification of appropriate data and metadata to be gathered, along with established procedures for their collection, documentation, and management. Furthermore, suitable approaches must be implemented to evaluate and ensure the quality of the data. Therefore, the 'Europe Regional Chapter of the International Society of Exposure Science' (ISES Europe) human biomonitoring working group (ISES Europe HBM WG) proposes the development of a FAIR Environment and health registry (FAIREHR) (hereafter FAIREHR). FAIR Environment and health registry offers preregistration of studies on exposure sciences and environmental epidemiology using HBM (as a starting point) across all areas of environmental and occupational health globally. The registry is proposed to receive a dedicated web-based interface, to be electronically searchable and to be available to all relevant data providers, users and stakeholders. Planned Human biomonitoring studies would ideally be registered before formal recruitment of study participants. The resulting FAIREHR would contain public records of metadata such as study design, data management, an audit trail of major changes to planned methods, details of when the study will be completed, and links to resulting publications and data repositories when provided by the authors. The FAIREHR would function as an integrated platform designed to cater to the needs of scientists, companies, publishers, and policymakers by providing user-friendly features. The implementation of FAIREHR is expected to yield significant benefits in terms of enabling more effective utilization of human biomonitoring (HBM) data.

It provides information on real-life human exposures and is increasingly used to prioritize chemicals of health concern and to evaluate the success of chemical policies. Europe has launched the ambitious REACH program in 2007 to improve the protection of human health and the environment. In October 2020 the EU commission published its new chemicals strategy for sustainability towards a toxic-free environment. The European Parliament called upon the commission to collect human biomonitoring data to support chemical’s risk assessment and risk management. This manuscript describes the organization of the first HBM4EU-aligned studies that obtain comparable human biomonitoring (HBM) data of European citizens to monitor their internal exposure to environmental chemicals. The HBM4EU-aligned studies build on existing HBM capacity in Europe by aligning national or regional HBM studies. The HBM4EU-aligned studies focus on three age groups: children, teenagers, and adults. The participants are recruited between 2014 and 2021 in 11 to 12 primary sampling units that are geographically distributed across Europe. Urine samples are collected in all age groups, and blood samples are collected in children and teenagers. Auxiliary information on sociodemographics, lifestyle, health status, environment, and diet is collected using questionnaires. In total, biological samples from 3137 children aged 6–12 years are collected for the analysis of biomarkers for phthalates, HEXAMOLL® DINCH, and flame retardants. Samples from 2950 teenagers aged 12–18 years are collected for the analysis of biomarkers for phthalates, Hexamoll® DINCH, and per and polyfluoroalkyl substances (PFASs), and samples from 3522 adults aged 20–39 years are collected for the analysis of cadmium, bisphenols, and metabolites of polyaromatic hydrocarbons (PAHs). The children’s group consists of 50.4% boys and 49.5% girls, of which 44.1% live in cities, 29.0% live in towns/suburbs, and 26.8% live in rural areas. The teenagers’ group includes 50.6% girls and 49.4% boys, with 37.7% of residents in cities, 31.2% in towns/suburbs, and 30.2% in rural areas. The adult group consists of 52.6% women and 47.4% men, 71.9% live in cities, 14.2% in towns/suburbs, and only 13.4% live in rural areas. The study population approaches the characteristics of the general European population based on age-matched EUROSTAT EU-28, 2017 data; however, individuals who obtained no to lower educational level (ISCED 0–2) are under represented. The data on internal human exposure to priority chemicals from this unique cohort will provide a baseline for Europe’s strategy towards a non-toxic environment and challenges and recommendations to improve the sampling frame for future EU-wide HBM surveys are discussed.
- Harmonized human biomonitoring in European children, teenagers and adults: EU-wide exposure data of 11 chemical substance groups from the HBM4EU Aligned Studies (2014-2021)Publication .

This survey has built on existing HBM capacity in Europe by aligning national or regional HBM studies, referred to as the HBM4EU Aligned Studies. The HBM4EU Aligned Studies included a total of 10,795 participants of three age groups: (i) 3,576 children aged 6–12 years, (ii) 3,117 teenagers aged 12–18 years and (iii) 4,102 young adults aged 20–39 years. The participants were recruited between 2014 and 2021 in 11–12 countries per age group, geographically distributed across Europe. Depending on the age group, internal exposure to phthalates and the substitute DINCH, halogenated and organophosphorus flame retardants, per- and polyfluoroalkyl substances (PFASs), cadmium, bisphenols, polycyclic aromatic hydrocarbons (PAHs), arsenic species, acrylamide, mycotoxins (deoxynivalenol (total DON)), benzophenones and selected pesticides was assessed by measuring substance specific biomarkers subjected to stringent quality control programs for chemical analysis. For substance groups analyzed in different age groups higher average exposure levels were observed in the youngest age group, i.e., phthalates/DINCH in children versus teenagers, acrylamide and pesticides in children versus adults, benzophenones in teenagers versus adults. Many biomarkers in teenagers and adults varied significantly according to educational attainment, with higher exposure levels of bisphenols, phthalates, benzophenones, PAHs and acrylamide in participants (from households) with lower educational attainment, while teenagers from households with higher educational attainment have higher exposure levels for PFASs and arsenic. In children, a social gradient was only observed for the non-specific pyrethroid metabolite 3-PBA and di-isodecyl phthalate (DiDP), with higher levels in children from households with higher educational attainment. Geographical variations were seen for all exposure biomarkers. For 15 biomarkers, the available health-based HBM guidance values were exceeded with highest exceedance rates for toxicologically relevant arsenic in teenagers (40%), 3-PBA in children (36%), and between 11 and 14% for total DON, Σ (PFOA + PFNA + PFHxS + PFOS), bisphenol S and cadmium. The infrastructure and harmonized approach succeeded in obtaining comparable European wide internal exposure data for a prioritized set of 11 chemical groups. These data serve as a reference for comparison at the global level, provide a baseline to compare the efficacy of the European Commission's chemical strategy for sustainability and will give leverage to national policy makers for the implementation of targeted measures.
- Implementation of effect biomarkers in human biomonitoring studies: A systematic approach synergizing toxicological and epidemiological knowledgePublication . Rodríguez-Carrillo, Andrea; Mustieles, Vicente; Salamanca-Fernández, Elena; Olivas-Martínez, Alicia; Suárez, Beatriz; Bajard, Lola; Baken, Kirsten; Blaha, Ludek; Bonefeld-Jørgensen, Eva Cecilie; Couderq, Stephan; D'Cruz, Shereen Cynthia; Fini, Jean-Baptiste; Govarts, Eva; Gundacker, Claudia; Hernández, Antonio F.; Lacasaña, Marina; Laguzzi, Federica; Linderman, Birgitte; Long, Manhai; Louro, Henriqueta; Neophytou, Christiana; Oberemn, Axel; Remy, Sylvie; Rosenmai, Anna Kjerstine; Saber, Anne Thoustrup; Schoeters, Greet; Silva, Maria João; Smagulova, Fatima; Uhl, Maria; Vinggaard, Anne Marie; Vogel, Ulla; Wielsøe, Maria; Olea, Nicolás; Fernández, Mariana F.Human biomonitoring (HBM) studies have highlighted widespread daily exposure to environmental chemicals. Some of these are suspected to contribute to adverse health outcomes such as reproductive, neurological, and metabolic disorders, among other developmental and chronic impairments. One of the objectives of the H2020 European Human Biomonitoring Initiative (HBM4EU) was the development of informative effect biomarkers for application in a more systematic and harmonized way in large-scale European HBM studies. The inclusion of effect biomarkers would complement exposure data with mechanistically-based information on early and late adverse effects. For this purpose, a stepwise strategy was developed to identify and implement a panel of validated effect biomarkers in European HBM studies. This work offers an overview of the complete procedure followed, from comprehensive literature search strategies, selection of criteria for effect biomarkers and their classification and prioritization, based on toxicological data and adverse outcomes, to pilot studies for their analytical, physiological, and epidemiological validation. We present the example of one study that demonstrated the mediating role of the effect biomarker status of brain-derived neurotrophic factor BDNF in the longitudinal association between infant bisphenol A (BPA) exposure and behavioral function in adolescence. A panel of effect biomarkers has been implemented in the HBM4EU Aligned Studies as main outcomes, including traditional oxidative stress, reproductive, and thyroid hormone biomarkers. Novel biomarkers of effect, such as DNA methylation status of BDNF and kisspeptin (KISS) genes were also evaluated as molecular markers of neurological and reproductive health, respectively. A panel of effect biomarkers has also been applied in HBM4EU occupational studies, such as micronucleus analysis in lymphocytes and reticulocytes, whole blood comet assay, and malondialdehyde, 8-oxo-2′-deoxyguanosine and untargeted metabolomic profile in urine, to investigate, for example, biological changes in response to hexavalent chromium Cr(VI) exposure. The use of effect biomarkers in HBM4EU has demonstrated their ability to detect early biological effects of chemical exposure and to identify subgroups that are at higher risk. The roadmap developed in HBM4EU confirms the utility of effect biomarkers, and support one of the main objectives of HBM research, which is to link exposure biomarkers to mechanistically validated effect and susceptibility biomarkers in order to better understand the public health implications of human exposure to environmental chemicals.
- A Tiered Approach for Assessing Individual and Combined Risk of Pyrethroids Using Human Biomonitoring DataPublication . Tarazona, Jose; Cattaneo, Irene; Niemann, Lars; Pedraza-Diaz, Susana; González-Caballero, MCarmen; Alba-Gonzalez, Mercedes de; Cañas, Ana; Domínguez-Morueco, Noelia; Esteban, Marta; Castano, Argelia; Borges, Teresa; Katsonouri, Andromachi; Makris, Konstantinos C.; Ottenbros, Ilse; Mol, Hans; De Decker, Annelies; Morrens, Bert; Berman, Tamar; Barnett-Itzhaki, Zohar; Probst-Hensch, Nicole; Fuhrimann, Samuel; Snoj Tratnik, Janja; Horvat, Milena; RAMBAUD, Loic; RIOU, Margaux; Schoeters, Greta; Govarts, Eva; Kolossa-Gehring, Marike; Weber, Till; Apel, Petra; Namorado, Sónia; Santonen, TiinaPyrethroids are a major insecticide class, suitable for biomonitoring in humans. Due to similarities in structure and metabolic pathways, urinary metabolites are common to various active substances. A tiered approach is proposed for risk assessment. Tier I was a conservative screening for overall pyrethroid exposure, based on phenoxybenzoic acid metabolites. Subsequently, probabilistic approaches and more specific metabolites were used for refining the risk estimates. Exposure was based on 95th percentiles from HBM4EU aligned studies (2014–2021) covering children in Belgium, Cyprus, France, Israel, Slovenia, and The Netherlands and adults in France, Germany, Israel, and Switzerland. In all children populations, the 95th percentiles for 3-phenoxybenzoic acid (3-PBA) exceeded the screening value. The probabilistic refinement quantified the risk level of the most exposed population (Belgium) at 2% or between 1–0.1% depending on the assumptions. In the substance specific assessments, the 95th percentiles of urinary concentrations in the aligned studies were well below the respective human biomonitoring guidance values (HBM-GVs). Both information sets were combined for refining the combined risk. Overall, the HBM data suggest a low health concern, at population level, related to pyrethroid exposure for the populations covered by the studies, even though a potential risk for highly exposed children cannot be completely excluded. The proposed tiered approach, including a screening step and several refinement options, seems to be a promising tool of scientific and regulatory value in future.
- Time Trends of Acrylamide Exposure in Europe: Combined Analysis of Published Reports and Current HBM4EU StudiesPublication . Poteser, Michael; Laguzzi, Federica; Schettgen, Thomas; Vogel, Nina; Weber, Till; Zimmermann, Philipp; Hahn, Domenica; Kolossa-Gehring, Marike; Namorado, Sónia; Van Nieuwenhuyse, An; Appenzeller, Brice; Halldorsson, Thorhallur; Eiríksdóttir, Ása; Haug, Line Småstuen; Thomsen, Cathrine; Barbone, Fabio; Rosolen, Valentina; RAMBAUD, Loic; RIOU, Margaux; Göen, Thomas; Nübler, Stefanie; Schäfer, Moritz; Haji-Abbas-Zarrabi, Karin; Gilles, Liese; Rodriguez Martin, Laura; Schoeters, Greta; Sepai, Ovnair; Govarts, Eva; Moshammer, HannsMore than 20 years ago, acrylamide was added to the list of potential carcinogens found in many common dietary products and tobacco smoke. Consequently, human biomonitoring studies investigating exposure to acrylamide in the form of adducts in blood and metabolites in urine have been performed to obtain data on the actual burden in different populations of the world and in Europe. Recognizing the related health risk, the European Commission responded with measures to curb the acrylamide content in food products. In 2017, a trans-European human biomonitoring project (HBM4EU) was started with the aim to investigate exposure to several chemicals, including acrylamide. Here we set out to provide a combined analysis of previous and current European acrylamide biomonitoring study results by harmonizing and integrating different data sources, including HBM4EU aligned studies, with the aim to resolve overall and current time trends of acrylamide exposure in Europe. Data from 10 European countries were included in the analysis, comprising more than 5500 individual samples (3214 children and teenagers, 2293 adults). We utilized linear models as well as a non-linear fit and breakpoint analysis to investigate trends in temporal acrylamide exposure as well as descriptive statistics and statistical tests to validate findings. Our results indicate an overall increase in acrylamide exposure between the years 2001 and 2017. Studies with samples collected after 2018 focusing on adults do not indicate increasing exposure but show declining values. Regional differences appear to affect absolute values, but not the overall time-trend of exposure. As benchmark levels for acrylamide content in food have been adopted in Europe in 2018, our results may imply the effects of these measures, but only indicated for adults, as corresponding data are still missing for children.
- Trends of Exposure to Acrylamide as Measured by Urinary Biomarkers Levels within the HBM4EU Biomonitoring Aligned Studies (2000–2021)Publication . Poteser, Michael; Laguzzi, Federica; Schettgen, Thomas; Vogel, Nina; Weber, Till; Murawski, Aline; Schmidt, Phillipp; Rüther, Maria; Kolossa-Gehring, Marike; Namorado, Sónia; Van Nieuwenhuyse, An; Appenzeller, Brice; Dufthaksdóttir, Edda; Olafsdottir, Kristin; Haug, Line Småstuen; Thomsen, Cathrine; Barbone, Fabio; Rosolen, Valentina; RAMBAUD, Loic; RIOU, Margaux; Göen, Thomas; Nübler, Stefanie; Schäfer, Moritz; Zarrabi, Karin H.A.; Gilles, Liese; Rodriguez Martin, Laura; Schoeters, Greta; Sepai, Ovnair; Govarts, Eva; Moshammer, HannsAcrylamide, a substance potentially carcinogenic in humans, represents a very prevalent contaminant in food and is also contained in tobacco smoke. Occupational exposure to higher concentrations of acrylamide was shown to induce neurotoxicity in humans. To minimize related risks for public health, it is vital to obtain data on the actual level of exposure in differently affected segments of the population. To achieve this aim, acrylamide has been added to the list of substances of concern to be investigated in the HBM4EU project, a European initiative to obtain biomonitoring data for a number of pollutants highly relevant for public health. This report summarizes the results obtained for acrylamide, with a focus on time-trends and recent exposure levels, obtained by HBM4EU as well as by associated studies in a total of seven European countries. Mean biomarker levels were compared by sampling year and time-trends were analyzed using linear regression models and an adequate statistical test. An increasing trend of acrylamide biomarker concentrations was found in children for the years 2014–2017, while in adults an overall increase in exposure was found to be not significant for the time period of observation (2000–2021). For smokers, represented by two studies and sampling for, over a total three years, no clear tendency was observed. In conclusion, samples from European countries indicate that average acrylamide exposure still exceeds suggested benchmark levels and may be of specific concern in children. More research is required to confirm trends of declining values observed in most recent years.
- Utilização de biomonitorização humana para avaliação da exposição a cádmio na população portuguesaPublication . Alberto, Ana Rita; Coelho, Inês; Delgado, Inês; Gueifão, Sandra; Ventura, Marta; Silva, Susana; Tratnik, Janja Snoj; Govarts, Eva; Schoeters, Greet; Namorado, SóniaO cádmio é um metal pesado tóxico e carcinogénico, que representa uma ameaça séria para a saúde humana. A população geral pode encontrar-se exposta ao cádmio por diversas vias e o estudo INSEF-ExpoQuim visou caracterizar a exposição da população portuguesa adulta (28-39 anos ) a este agente químico através de um estudo transversal. Este estudo incluiu 295 indivíduos, os quais reponderam a um questionário (dados sociodemográficos, de estilos de vida e possíveis vias de exposição ) e facultaram uma amostra de urina para quantificação de cádmio por espectrometria de massa com plasma indutivo acoplado ( ICP- -MS ). Observou-se uma média geométrica de 0,092 μg Cd/g creatinina [ IC ( 95%): 0,084-0,101 ], apresentando as mulheres valores mais elevados ( 0,103 vs 0,079 ), bem como os fumadores ( 0,135 vs 0,081).
