1. A data synthesis framework & case study supporting Risk-Based prioritization of additives & polymer-associated chemistries (APAC).
This paper proposes a practical, scalable data synthesis framework to support risk-based screening and prioritization of additives and polymer-associated chemistries across consumer products regulated under TSCA/REACH and the FD&C Act. Applying the framework to 13,186 APAC from the UNEP database showed Tier 1+ data are publicly available for 66.9% (human health) and 68.8% (environment), enabling downstream risk assessment and highlighting data gaps.
Impact: Provides a transparent, reproducible approach to triage thousands of polymer-associated chemicals—including those used in cosmetic articles—so regulators and industry can focus resources on higher-risk substances.
Clinical Implications: While indirect, prioritized risk assessment of APAC supports safer consumer and cosmetic products, reducing potential exposure-related health risks and informing clinician counseling about product safety.
Key Findings
- Introduced a data synthesis framework for risk-based screening and prioritization of APAC.
- Case study covered 13,186 APAC identified in the UNEP Chemicals in Plastics report.
- Tier 1+ public data were available for 66.9% (8,819) for human health and 68.8% (9,068) for environmental assessment.
- Framework clarifies where to gather, organize, and process data for downstream risk assessment and identifies data gaps.
Methodological Strengths
- Scalable, transparent framework applied to a very large chemical universe (13,186 APAC).
- Tiered evidence approach enables reproducible prioritization across health and environmental endpoints.
Limitations
- Relies on publicly available data; quality and completeness may vary.
- Tier 1+ availability does not guarantee adequate detail for quantitative risk assessment; empirical exposure measurements are limited.
Future Directions: Integrate biomonitoring and exposure modeling, include cosmetic-use scenarios, and adopt probabilistic risk methods with open data/code to enhance reproducibility and regulatory uptake.
Polymers and plastics are widely used to support a range of growing market segments and applications (e.g.,, packaging, construction, agricultural films) due to functional properties (e.g.,, durability, versatility) and cost effectiveness. With continued growing use of polymers and plastics, there is increased interest in health and environmental assessments of these materials, including chemicals associated with their production and use. Additives and polymer-associated chemistries (APAC), as individual chemicals, are subject to regulation by chemical assessment frameworks (e.g.,, U.S. TSCA, EU REACH). Finished products and articles are subject to other regulations (e.g.,, U.S. FDA Federal Food, Drug, and Cosmetic Act). Assessing risk (ie, hazard x exposure) and making risk-based decisions requires analysis of a complex, dynamic dataset. There is a need for practical screening and prioritization methods to address the large numbers and complexity of APAC. Therefore, a data synthesis framework supporting risk-based screening and prioritization of APAC is proposed to demonstrate where and how to gather, organize, and process data for downstream human health and environmental risk assessment of APAC (ie in articles). A case study was performed using the 13,186 APAC identified in the UNEP Chemicals in Plastics report to evaluate the utility of this data synthesis framework and evaluate how many APAC have sufficient publicly available data to perform downstream risk assessment. Based on application of this framework, it was determined that at a minimum Tier 1 + data are readily accessible to support risk-based screening and prioritization of most of the UNEP database APAC for human health (8,819 or 66.9%) and environmental (9,068 or 68.8%) risk assessment.
2. Determination of 116 Pharmaceuticals and Personal Care Products in Water by Ultra-High Performance Liquid Chromatography-Tandem Mass Spectrometry.
The authors validated a high-sensitivity SPE–UHPLC–MS/MS workflow for 116 PPCPs with sub-ng/L detection limits and robust recoveries, then detected 47 compounds (up to 359 ng/L) across raw, treated, and river waters in Hangzhou. Notably, melamine, loratadine, aldosterone, and levothyroxine sodium were reported for the first time in aquatic environments, enabling stronger surveillance of PPCP contamination.
Impact: Delivers a validated, multiplex analytical method with first-in-environment detections, directly enabling environmental surveillance of personal care contaminants and informing exposure assessment and regulatory monitoring.
Clinical Implications: Indirectly informs clinicians and public health by characterizing environmental PPCP burdens that may translate to human exposure through water, supporting risk communication and upstream prevention.
Key Findings
- Validated SPE–UHPLC–MS/MS method for 116 PPCPs with R > 0.99 across 5–800 ng/mL.
- Achieved LODs of 0.0136–13.3 ng/L and LOQs of 0.0452–44.4 ng/L; recoveries 53.1–116.5% (RSD < 9.9%).
- Detected 47 compounds (up to 359 ng/L) in raw, treated, and river waters from Hangzhou.
- First aquatic detections reported for melamine, loratadine, aldosterone, and levothyroxine sodium.
Methodological Strengths
- Systematic optimization of SPE, UHPLC, and MS/MS parameters with seven-point calibration.
- Demonstrated low matrix interference, high sensitivity, and precision across multiple water matrices.
Limitations
- Recoveries as low as ~53% for some analytes may affect quantitation.
- Single-region application (Hangzhou) with limited temporal coverage; no human exposure or risk quantification.
Future Directions: Expand to multi-region/time-series monitoring, couple with wastewater-based epidemiology and health risk assessment, and target additional cosmetic-related PPCPs and transformation products.
This study examined an improved and simplified method for solid-phase extraction that provides rapid and accurate determination and identification of 116 pharmaceutical and personal care products (PPCPs) in an aqueous environment using ultra-high performance liquid chromatography-tandem mass spectrometry. The common active compounds include 22 sulfonamides, 18 quinolones, 8 macrolides, 18 β-agonists, 6 sedative-hypnotics, 3 antipyretic-analgesics, 3 antihypertensives, 2 antidiabetic drugs, 3 antihistamines, 8 sex hormones, 2 antivirals, 6 nitroimidazoles, 8 glucocorticoids, and 3 amphenicols, lincomycin, pimaricin, levothyroxine sodium, bisphenol A, aldosterone, and melamine in water samples. Key parameters of tandem mass spectrometry, ultra-high performance liquid chromatography, and solid-phase extraction were optimized to enhance the analytical performance. The calibration curves were accomplished at seven concentration levels, and a satisfactory linear relationship (R > 0.99) was observed within the range of 5-800 ng/mL. Results showed varying limits of detection (0.0136-13.3 ng/L for different analytes based on signal-to-noise (S/N) = 3) and limits of quantitation (0.0452-44.4 ng/L). Recoveries of the spiked samples ranged from 53.1% to 116.5% with relative standard deviation lower than 9.9%. This approach effectively minimized matrix interference, improved extraction efficiency, and enhanced detection sensitivity, enabling more accurate PPCP residue analysis in water. The validated method was applied to raw water, treated water, and river water samples from Hangzhou, detecting 47 compounds at concentrations ranging from nondetected to 359 ng/L. Our findings provided critical technical support for the preliminary establishment of an environmental monitoring system targeting emerging pollutants. Notably, to the best of our knowledge, this study represented the first reported detection of melamine, loratadine, aldosterone, and levothyroxine sodium in aquatic environments. In particular, melamine was detected in aquatic environment for the first time, thus expanding the understanding of PPCPs' pollution status.

INTRODUCTION: This is the 42nd Annual Report of America's Poison Centers METHODS: We analyzed the case data, tabulating specific indices from the NPDS. The methodology was as in previous years. Where changes were introduced, the differences are identified. Cases with medical outcomes of death were evaluated by a team of medical and clinical toxicologists using an ordinal scale of 1-6 to assess the Relative Contribution to Fatality of the exposure. RESULTS: In 2024, 2,418,426 closed encounters were logged by the National Poison Data System: 2,092,689 human exposures, 34,919 animal exposures, 285,736 information requests, 5,054 human confirmed nonexposures, and 28 animal confirmed nonexposures. The upload interval was 4.97 [4.32, 9.32] (median [25%, 75%]) minutes, creating a near real-time national exposure and information database and surveillance system. Total encounters remained essentially constant with a 0.117% decrease from 2023 while human exposure cases increased by 0.578% and health care facility human exposure cases increased by 0.661%. All information requests decreased by 2.70%, medication identification (Drug ID) requests decreased by 17.0%, and medical information requests showed a 24.5% decrease. Drug Information requests showed a 0.218% increase and comprised 22.4% of all information contacts. Human exposures with less serious outcomes have decreased by 1.45% per year since 2008, while those with more serious outcomes (moderate, major or death) have increased by 4.08% per year since 2000.Consistent with the previous year, the top 5 substance classes most frequently involved in all human exposures were analgesics (10.5%), household cleaning substances (6.94%), antidepressants (5.50%), cardiovascular drugs (5.12%) and cosmetics/personal care products (4.96%). As a class, stimulants and street drug exposures increased most rapidly, by 813 cases/year (4.54%/year) over the past 10 years for cases with more serious outcomes.The top 5 most common exposures in children aged 5 years or less were household cleaning substances (9.96%), cosmetics/personal care products (9.15%), analgesics (8.85%), foreign bodies/toys/miscellaneous (7.92%), and dietary supplements/herbals/homeopathic (6.34%).The National Poison Data System documented 2,809 human exposures resulting in death; 2,271 (80.9%) of these were judged as related (Relative Contribution to Fatality of 1-Undoubtedly responsible, 2-Probably responsible, or 3-Contributory). CONCLUSIONS: These data support the continued value of Poison Center expertise and the need for specialized medical toxicology information to manage the increasing number of more serious exposures. Unintentional and intentional exposures continue to be a significant cause of morbidity and mortality in the US. The near real-time nature of the National Poison Data System represents a national public health resource for collecting and monitoring US exposure cases and information requests. The continuing mission of the National Poison Data System is to provide a nationwide infrastructure for surveillance for all types of exposures (e.g., foreign body, infectious, venomous, chemical agent, or commercial product), and the identification and tracking of significant public health events. The National Poison Data System is a model system for the near real-time surveillance of national and global public health.
