- A critical review to identify data gaps and improve risk assessment of bisphenol A alternatives for human healthPublication . Mhaouty-Kodja, Sakina; Zalko, Daniel; Tait, Sabrina; Testai, Emanuela; Viguié, Catherine; Corsini, Emanuela; Grova, Nathalie; Buratti, Franca Maria; Cabaton, Nicolas J.; Coppola, Lucia; De la Vieja, Antonio; Dusinska, Maria; El Yamani, Naouale; Galbiati, Valentina; Iglesias-Hernández, Patricia; Kohl, Yvonne; Maddalon, Ambra; Marcon, Francesca; Naulé, Lydie; Rundén-Pran, Elise; Salani, Francesca; Santori, Nicoletta; Torres-Ruiz, Mónica; Turner, Jonathan D.; Adamovsky, Ondrej; Aiello-Holden, Kiara; Dirven, Hubert; Louro, Henriqueta; Silva, Maria JoãoBisphenol A (BPA), a synthetic chemical widely used in the production of polycarbonate plastic and epoxy resins, has been associated with a variety of adverse effects in humans including metabolic, immunological, reproductive, and neurodevelopmental effects, raising concern about its health impact. In the EU, it has been classified as toxic to reproduction and as an endocrine disruptor and was thus included in the candidate list of substances of very high concern (SVHC). On this basis, its use has been banned or restricted in some products. As a consequence, industries turned to bisphenol alternatives, such as bisphenol S (BPS) and bisphenol F (BPF), which are now found in various consumer products, as well as in human matrices at a global scale. However, due to their toxicity, these two bisphenols are in the process of being regulated. Other BPA alternatives, whose potential toxicity remains largely unknown due to a knowledge gap, have also started to be used in manufacturing processes. The gradual restriction of the use of BPA underscores the importance of understanding the potential risks associated with its alternatives to avoid regrettable substitutions. This review aims to summarize the current knowledge on the potential hazards related to BPA alternatives prioritized by European Regulatory Agencies based on their regulatory relevance and selected to be studied under the European Partnership for the Assessment of Risks from Chemicals (PARC): BPE, BPAP, BPP, BPZ, BPS-MAE, and TCBPA. The focus is on data related to toxicokinetic, endocrine disruption, immunotoxicity, developmental neurotoxicity, and genotoxicity/carcinogenicity, which were considered the most relevant endpoints to assess the hazard related to those substances. The goal here is to identify the data gaps in BPA alternatives toxicology and hence formulate the future directions that will be taken in the frame of the PARC project, which seeks also to enhance chemical risk assessment methodologies using new approach methodologies (NAMs).

HBM can help to improve chemical policies in five major key areas: (1) assessing internal and aggregate exposure in different target populations; 2) assessing exposure to chemicals across life stages; (3) assessing combined exposure to multiple chemicals (mixtures); (4) bridging regulatory silos on aggregate exposure; and (5) enhancing the effectiveness of risk management measures. In this strategy paper we propose a vision and a strategy for the use of HBM in chemical regulations and public health policy in Europe and beyond. We outline six strategic objectives and a roadmap to further strengthen HBM approaches and increase their implementation in the regulatory risk assessment of chemicals to enhance our understanding of exposure and health impacts, enabling timely and targeted policy interventions and risk management. These strategic objectives are: 1) further development of sampling strategies and sample preparation; 2) further development of chemical-analytical HBM methods; 3) improving harmonisation throughout the HBM research life cycle; 4) further development of quality control / quality assurance throughout the HBM research life cycle; 5) obtain sustained funding and reinforcement by legislation; and 6) extend target-specific communication with scientists, policymakers, citizens and other stakeholders. HBM approaches are essential in risk assessment to address scientific, regulatory and societal challenges. HBM requires full and strong support from the scientific and regulatory domain to reach its full potential in public and occupational health assessment and in regulatory decision-making.

The accurate interpretation and comparability of biomarkers of exposure and effect depend on harmonized, quality-assured sampling, processing, and analysis. Currently, the lack of broadly accepted guidance on minimum information required for collecting and reporting HBM data, hinders comparability between studies. Furthermore, it prevents HBM from reaching its full potential as a reliable approach for assessing and managing the risks of human exposure to chemicals. The European Chapter of the International Society of Exposure Science HBM Working Group (ISES Europe HBM working group) has established a global human biomonitoring community network (HBM Global Network) to develop a guidance to define the minimum information to be collected and reported in HBM, called the “Minimum Information Requirements for Human Biomonitoring (MIR-HBM)”. This work builds on previous efforts to harmonize HBM worldwide. The MIR-HBM guidance covers all phases of HBM from the design phase to the effective communication of results. By carefully defining MIR for all phases, researchers and health professionals can make their HBM studies and programs are robust, reproducible, and meaningful. Acceptance and implementation of MIR-HBM Guidelines in both the general population and occupational fields would improve the interpretability and regulatory utility of HBM data. While implementation challenges remain—such as varying local capacities, and ethical and legal differences at the national levels, this initiative represents an important step toward harmonizing HBM practice and supports an ongoing dialogue among policymakers, legal experts, and scientists to effectively address these challenges. Leveraging the data and insights from HBM, policymakers can develop more effective strategies to protect public health and ensure safer working environments.
- Hazard assessment of bisphenol A alternatives to close data gaps of concern for human health and improve their risk assessmentPublication . Aiello Holden, Kiara; Tait, Sabrina; Viguié, Catherine; Mhaouty-Kodja, Sakina; Corsini, Emanuela; Silva, Maria João; Zalko, Daniel; Testai, Emanuela; Louro, Henriqueta; Dirven, HubertWHY? With the upcoming restrictions on BPA, BPA alternatives’ tonnages and frequencies of use are expected to severely increase in the coming years. Therefore, this project aims to fill the identified data gaps, providing a complete data set for at least four relevant BPA alternatives identified in an ad hoc Workshop together with ECHA and EFSA. We will fill the knowledge gaps on human health on five toxicological endpoints and by the identification of molecular biomarkers we will contribute to develop methods to rapidly predict the possible effects of BPA alternatives.
- Hazard characterization of Alternaria toxins to identify data gaps and improve risk assessment for human healthPublication . Louro, Henriqueta; Vettorazzi, Ariane; López de Cerain, Adela; Spyropoulou, Anastasia; Solhaug, Anita; Straumfors, Anne; Behr, Anne-Cathrin; Mertens, Birgit; Žegura, Bojana; Fæste, Christiane Kruse; Ndiaye, Dieynaba; Spilioti, Eliana; Varga, Elisabeth; Dubreil, Estelle; Borsos, Eszter; Crudo, Francesco; Eriksen, Gunnar Sundstøl; Snapkow, Igor; Henri, Jérôme; Sanders, Julie; Machera, Kyriaki; Gaté, Laurent; Le Hegarat, Ludovic; Novak, Matjaž; Smith, Nicola M.; Krapf, Solveig; Hager, Sonja; Fessard, Valérie; Kohl, Yvonne; Silva, Maria João; Dirven, Hubert; Dietrich, Jessica; Marko, DorisFungi of the genus Alternaria are ubiquitous plant pathogens and saprophytes which are able to grow under varying temperature and moisture conditions as well as on a large range of substrates. A spectrum of structurally diverse secondary metabolites with toxic potential has been identified, but occurrence and relative proportion of the different metabolites in complex mixtures depend on strain, substrate, and growth conditions. This review compiles the available knowledge on hazard identification and characterization of Alternaria toxins. Alternariol (AOH), its monomethylether AME and the perylene quinones altertoxin I (ATX-I), ATX-II, ATX-III, alterperylenol (ALP), and stemphyltoxin III (STTX-III) showed in vitro genotoxic and mutagenic properties. Of all identified Alternaria toxins, the epoxide-bearing analogs ATX-II, ATX-III, and STTX-III show the highest cytotoxic, genotoxic, and mutagenic potential in vitro. Under hormone-sensitive conditions, AOH and AME act as moderate xenoestrogens, but in silico modeling predicts further Alternaria toxins as potential estrogenic factors. Recent studies indicate also an immunosuppressive role of AOH and ATX-II; however, no data are available for the majority of Alternaria toxins. Overall, hazard characterization of Alternaria toxins focused, so far, primarily on the commercially available dibenzo-α-pyrones AOH and AME and tenuazonic acid (TeA). Limited data sets are available for altersetin (ALS), altenuene (ALT), and tentoxin (TEN). The occurrence and toxicological relevance of perylene quinone-based Alternaria toxins still remain to be fully elucidated. We identified data gaps on hazard identification and characterization crucial to improve risk assessment of Alternaria mycotoxins for consumers and occupationally exposed workers.
- Hazard characterization of the mycotoxins enniatins and beauvericin to identify data gaps and improve risk assessment for human healthPublication . Behr, Anne-Cathrin; Fæste, Christiane Kruse; Azqueta, Amaya; Tavares, Ana M.; Spyropoulou, Anastasia; Solhaug, Anita; Olsen, Ann-Karin; Vettorazzi, Ariane; Mertens, Birgit; Zegura, Bojana; Streel, Camille; Ndiaye, Dieynaba; Spilioti, Eliana; Dubreil, Estelle; Buratti, Franca Maria; Crudo, Francesco; Eriksen, Gunnar Sundstøl; Snapkow, Igor; Teixeira, João Paulo; Rasinger, Josef D.; Sanders, Julie; Machera, Kyriaki; Ivanova, Lada; Gaté, Laurent; Le Hegarat, Ludovic; Novak, Matjaz; Smith, Nicola M.; Tait, Sabrina; Fraga, Sónia; Hager, Sonja; Marko, Doris; Braeuning, Albert; Louro, Henriqueta; Silva, Maria João; Dirven, Hubert; Dietrich, JessicaEnniatins (ENNs) and beauvericin (BEA) are cyclic hexadepsipeptide fungal metabolites which have demonstrated antibiotic, antimycotic, and insecticidal activities. The substantial toxic potentials of these mycotoxins are associated with their ionophoric molecular properties and relatively high lipophilicities. ENNs occur extensively in grain and grain-derived products and are considered a food safety issue by the European Food Safety Authority (EFSA). The tolerable daily intake and maximum levels for ENNs in humans and animals remain unestablished due to key toxicological and toxicokinetic data gaps, preventing full risk assessment. Aiming to find critical data gaps impeding hazard characterization and risk evaluation, this review presents a comprehensive summary of the existing information from in vitro and in vivo studies on toxicokinetic characteristics and cytotoxic, genotoxic, immunotoxic, endocrine, reproductive and developmental effects of the most prevalent ENN analogues (ENN A, A1, B, B1) and BEA. The missing information identified showed that additional studies on ENNs and BEA have to be performed before sufficient data for an in-depth hazard characterisation of these mycotoxins become available.
- Hazard identification and characterization of leachable chemicals from plastic products – a new PARC projectPublication .

Plastic chemicals are released throughout the plastic life cycle, from production, use, disposal and recycling. Most of these chemicals have not been studied for potential hazardous properties for humans and in the environment. To refine the risk assessment of these leachable chemicals, additional hazard data are needed. The PlasticLeach project within the EU co-funded Partnership for the Assessment of Risks from Chemicals (PARC) aims to address this data gap by screening several plastic products in daily use. Leachates will be prepared from a number of these plastic items, and these chemical mixtures will be further tested using several test guideline compliant assays and New Approach Methodologies covering both human health and environmental endpoints. The most toxic leachates will be characterized using a non-targeted analysis pipeline to identify chemicals in the leachate. When single chemicals of concern are identified, these will be further tested to determine hazardous properties and identify the respective potency factors to better understand their specific hazard profiles. A tiered approach for hazard testing will be followed. The experimental work will be complemented by toxicological profiling, using publicly available toxicity databases and tools, including Artificial Intelligence tools that cover both human and environmental endpoints. A comprehensive array of endpoints, including cytotoxicity, endocrine disruption, genotoxicity, immunotoxicity, reproductive toxicity and effects related to ecotoxicity will be evaluated. In this paper, we outline the plastic products to be tested and the battery of assays that will be used to identify hazards relevant to both human health and the environment. Data generated from approaches will be reported using standardized formats, stored within a centralized repository, and harmonized to adhere to the FAIR data principles (Findable, Accessible, Interoperable, and Reusable). This integrated strategy will not only advance our understanding of the risks associated with plastic-derived chemicals but will also provide critical support for regulatory decision-making and facilitate the development of safer, and more ecofriendly plastic materials in the future.
