Discover Toxicology was inaugurated in May 2024 as a peer-reviewed, open access platform intended to publish research across all aspects of toxicology and its applications in research, development, and society. Its founding premise, the editors explain, is to give researchers, practitioners, policymakers, and stakeholders a venue to exchange knowledge, share best practices, and collaborate on solutions to pressing toxicological challenges. Like other journals in the Discover series, it welcomes all valid research, including null results, regardless of perceived impact, provided the work meets the standards of rigor and quality associated with Springer Nature. That policy is a deliberate counterweight to publication cultures that reward only headline-grabbing findings, a bias the editors argue has left critical dynamics of toxicological mechanisms in low-resourced countries understudied.

The breadth of the journal’s ambition is reflected in its Editorial Board, whose listed expertise spans toxins and venoms, clinical and preclinical pharmacology and toxicology, bioinformatics and cheminformatics, computational chemistry, ecotoxicity, regulatory toxicology, emerging contaminants, food safety, genetic toxicology, analytical chemistry, risk assessment, mechanisms of toxicity, omics, immunotoxicology, forensic pathology, and occupational exposure assessment. In the editorial, each Section Editor introduces the domain he or she represents, offering an unusually candid view of the technical questions the journal considers most pressing.

Professor Adekunle A. Bakare of the University of Ibadan, Nigeria, anchors the genotoxicology section. His laboratory studies the genotoxicity and mutagenicity of xenobiotics, the foreign chemicals that urbanization and industrialization have made almost impossible to avoid. Using in vitro and in vivo bioassays, his group examines the cytotoxic, genotoxic, and mutagenic effects of municipal solid waste leachates, industrial effluents, pesticides, analgesics, medicinal plant extracts, antiretroviral and antituberculosis drugs, metal and metal oxide nanoparticles, and electronic waste elutriates. The stakes, he argues, are generational: DNA damage from environmental xenobiotics is implicated not only in cancer and birth defects but also in heart disease, cellular aging, immune dysfunction, altered metabolism, neurodegenerative disease, and cataracts, and germline damage may affect future as well as current generations. He invites submissions on genotoxicity testing approaches, predictive toxicology, toxicogenomics, reproductive toxicology, epigenetics, gene expression analysis of DNA toxicity, artificial intelligence applied to DNA damage, and the links between genotoxicity and carcinogenesis.

Ajay Vikram Singh, a senior scientist at the German Federal Institute for Risk Assessment (BfR) in Berlin, represents the computational and nanotoxicology frontier. Working within an institute of more than 750 scientists that advises the German government on food and product safety, chemical risks, contaminants, animal protection, and consumer health, Singh combines advanced computational models, artificial intelligence, and nanoscale characterization to decipher how chemicals, nanomaterials, and biological systems interact. The goal is proactive safety assessment: predicting toxicity before products reach the market and enabling the design of inherently safer, so-called safer-by-design materials. He highlights the integration of multi-omics data with computational approaches, the nanobiophysics of mechanistic toxicology, and the regulatory challenges posed by complex novel materials, and he welcomes manuscripts using in silico methods, AI and machine learning-driven predictive toxicology, high-throughput screening data analysis, and mechanistic studies of engineered nanomaterials.

Edmond Sanganyado, associate professor at the University of Saskatchewan, works at the intersection of analytical chemistry and systems biology, developing tools that link exposure to toxicological effect through advanced omics technologies. He frames three questions that he believes will define the field: how to detect and quantify known and unknown toxicants and their metabolites quickly, cheaply, and reliably in real samples; how complex mixtures of pollutants affect organisms, ecosystems, and humans over a lifetime; and how to identify toxic substances in ways that stand up in court, keep pace with drug trends, and support public health. Big data, artificial intelligence, high-resolution mass spectrometry, and new approach methodologies, or NAMs, are driving all three disciplines, analytical, environmental, and forensic toxicology, toward mixture-based paradigms and toward reducing and replacing animal testing. But he cautions that publication norms emphasizing narrow novelty risk leaving the toxicology of low-resourced countries chronically understudied.

Neuropharmacologist João Paulo Capela of Portugal’s Fernando Pessoa University and the University of Porto brings the journal’s coverage to drugs of abuse and clinical toxicology. His research probes the brain actions of amphetamine-type stimulants and methylphenidate, both as illicit substances and as prescribed treatments for attention deficit hyperactivity disorder and other brain disorders. His central concern is translation: whether work is done in vitro or in animals, the purpose of mechanistic toxicology is to transfer findings to the human situation in order to prevent, mitigate, or treat adverse drug effects. He sees artificial intelligence-based tools as a promising means of elevating that mechanistic understanding, and he argues that new methodologies and models are essential for surveying how drugs and toxicants inflict damage at the cellular and molecular level.

Ecotoxicologist Maranda Esterhuizen, affiliated with the University of Helsinki and Häme University of Applied Sciences in Finland, specializes in pollution impact assessment and ecological restoration through nature-based solutions, with a deliberately transdisciplinary approach bridging environmental science and policy. She describes environmental toxicology as standing at a critical juncture, confronting complex chemical mixtures and climate-induced shifts in pollutant behavior, particularly in rapidly urbanizing regions. Her section invites research using adverse outcome pathways, omics technologies, and predictive modeling to understand toxicity across biological scales, and she singles out studies integrating climate change dynamics, urbanization, and chemical mixture interactions as especially welcome, because they mirror the compounded pressures ecosystems actually face.

Food and computational toxicologist Yu-Syuan Luo of National Taiwan University completes the editorial leadership roster. His focus is on human-relevant, mechanism-informed chemical safety evaluation at a time when data gaps for emerging contaminants, low-dose exposures, and complex mixtures impede timely regulatory decisions. Food toxicology, he notes, is pivotal for assessing ingredients, contaminants, and food-contact materials, especially for endpoints such as endocrine disruption and mixture toxicity. Computational toxicology complements it with scalable predictive tools, including in silico modeling, omics-based profiling, and data-driven hazard identification and prioritization, supporting the global shift away from traditional animal testing and toward more efficient, transparent, forward-looking risk assessment.

Taken together, the editorial sketches a discipline in methodological upheaval: from single-compound testing toward mixtures, from animal models toward new approach methodologies, from reactive hazard characterization toward AI-assisted prediction and safer-by-design chemistry. By welcoming null results and prioritizing rigor over novelty, Discover Toxicology is positioning itself as a home for precisely the unglamorous, reproducible, and globally inclusive work that this transition requires, and the editors close with an open invitation to researchers worldwide to submit work spanning fundamental questions and real-world applications alike.

The PANORAMIX consortium, comprising experts from multiple European institutions, has utilized a multifaceted methodology integrating chemical profiling with effect-based bioassays to evaluate authentic environmental, dietary, and human samples. By blending advanced analytical chemistry techniques, including high-resolution mass spectrometry, with sensitive in vitro bioassays, the researchers transcended traditional single-chemical paradigms. Their findings strikingly suggest that mixtures of chemicals—often at concentrations deemed individually innocuous—collectively trigger measurable biological effects, effects that cannot be adequately explained by the presence of known chemicals detected through standard monitoring.

This revelation underscores a critical blind spot in current risk assessments which predominantly rely on targeted chemical monitoring. Professor Anne Marie Vinggaard from the DTU National Food Institute emphasizes that the vast majority of mixture effects identified in real-life samples do not correlate with the chemicals currently regulated or routinely monitored. She advocates for an innovative risk assessment framework that marries effect-based bioassays with comprehensive chemical profiling, allowing for a more holistic and accurate estimation of risk posed by complex chemical mixtures in the environment and the human body.

Delving deeper into the chemical landscape, the study discovered an extensive presence of numerous substances across different matrices, including environmental samples, various food products, breast milk, and umbilical cord blood. Notably, this confirmed persistent exposure pathways that link environmental contamination directly to human populations, starting from the earliest developmental stages. Such evidence highlights a continuous and inescapable chemical encounter that begins in utero and extends into postnatal life, raising significant concerns about lifelong health impacts.

Interestingly, the research revealed that the biological activities of these chemical mixtures adhere to the principle of concentration addition. This principle indicates that even trace amounts of different substances can cumulatively produce discernible biological effects, reinforcing the necessity of considering mixture toxicology rather than isolated compound effects. This additive behavior complicates toxicological risk evaluation because low-dose exposures, often dismissed as safe, can combine to cause substantial biological perturbations.

Among the chemical culprits identified as substantial contributors to the overall risk are substances widely recognized for their persistence and bioaccumulation: per- and polyfluoroalkyl substances (PFAS), bisphenol A, dioxins, and polychlorinated biphenyls (PCBs). These “legacy pollutants,” despite regulatory restrictions implemented in past decades, continue to linger in the environment and human tissues, perpetuating chronic exposure scenarios. Their continued presence serves as a stark reminder that regulatory bans, while necessary, must be complemented by vigilant monitoring and remediation efforts to mitigate residual risks.

The study also performed epidemiological analyses which unearthed compelling associations relevant to public health. Specifically, prenatal exposure to PFAS was linked to reduced birth weights, an outcome with long-term implications, potentially predisposing individuals to a spectrum of metabolic and developmental disorders. Concurrently, elevated phthalate exposure was correlated with higher attention deficit hyperactivity disorder (ADHD) scores in children, suggesting that early-life chemical environments may influence neurodevelopmental trajectories. These findings illuminate how mixture exposures translate into tangible health outcomes, reinforcing the urgency to refine our risk assessment frameworks.

The PANORAMIX project’s outcomes resonate profoundly with ongoing policy discussions within the European Union regarding chemical safety legislation. They advocate for incorporating mixture effects explicitly into regulatory paradigms, moving beyond the traditional single-substance focus which underestimates real-world exposure risks. To achieve this, PANORAMIX pioneers the use of combined methodological approaches, integrating non-targeted chemical analyses, effect-based bioassays, and epidemiological data, to generate robust, actionable insights essential for evidence-based policymaking.

Technically, the project employed sophisticated high-resolution mass spectrometry-based suspect screening approaches capable of detecting a wide spectrum of known and unknown chemical entities. When paired with bioassays assessing cellular and molecular responses, this technology allowed for a nuanced characterization of toxicological profiles of complex mixtures. This synergy permits researchers to identify not only the chemical composition but also the functional biological impact, providing a multidimensional perspective critical for effective risk mitigation strategies.

Furthermore, the inclusion of non-targeted chemical analysis addresses a significant limitation in environmental health research: the inability of traditional analytical methods to detect unexpected or emerging contaminants. By casting a wider net, PANORAMIX uncovered chemicals previously unmonitored, which may contribute synergistically or additively to observed biological effects. This technological advancement paves the way for a paradigm shift in environmental monitoring and human biomonitoring programs.

The implications of this research extend beyond scientific discourse, highlighting a pressing call to action for global health stakeholders, regulatory agencies, and the scientific community. Embracing a “One Health” perspective, PANORAMIX demonstrates the interconnectedness of environmental quality, food safety, and human health, advocating for integrative risk assessments that reflect these linkages. In the era of increasing chemical complexity, such comprehensive approaches are indispensable for safeguarding public health and ensuring sustainable environmental stewardship.

In conclusion, the PANORAMIX project presents a compelling case that current chemical risk assessment frameworks, grounded in evaluating single substances, are fundamentally insufficient to detect and manage the combined risks posed by real-world chemical exposures. By integrating targeted and non-targeted chemical analyses, effect-based bioassays, and epidemiological approaches, PANORAMIX charts a forward-looking path that enhances our capacity to understand and mitigate the consequences of chemical mixtures. This research not only advances scientific knowledge but also equips policymakers with critical tools to shape future regulations better aligned with contemporary chemical realities.
