Advances in chemical monitoring have revealed inconsistencies in environmental risk assessments, prompting the European Commission to advocate for a \"one substance, one assessment\" (OS-OA) approach. As part of the EU Partnership for the Assessment of the Risk from Chemicals (PARC), this study examines the implementation and outcome of environmental risk assessments carried out within different regulatory frameworks, focusing on the aquatic environment. Using case studies on imidacloprid and deltamethrin, we highlight methodological differences and their implications for OS-OA. Our analysis reveals little consistency in the data used by assessments in different regulatory processes. This is partially due to the historical development of risk assessments. In addition, we show that new scientific data are not consistently incorporated into risk assessments, leading to delays and prolonged environmental risks. Finally, we demonstrate that low analytical sensitivities contribute to low detection rates in monitoring programs and hinder comparisons between prospective and retrospective risk assessments. Differences in data accessibility and validity assessments and lack of collaboration and varying involvement of Member States contribute to these inconsistencies and underscore the need for standardized methods. As a result of different data requirements, models, and protection goals, isolated risk assessments of the same substance lead to divergent outcomes. In cases where data gaps exist and safe uses cannot be demonstrated, we strongly recommend read-across of hazard assessments between regulations to support more efficient regulatory conclusions. In summary, our findings highlight the need for coherent regulation and risk assessment to improve environmental protection in the EU.</p>","PeriodicalId":13557,"journal":{"name":"Integrated Environmental Assessment and Management","volume":" ","pages":"1608-1622"},"PeriodicalIF":3.3,"publicationDate":"2026-09-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"147689872","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"环境科学与生态学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

These contaminants accumulate in the environment and aquaculture products. Since the residents in Eastern China have a dietary preference for specific foods (e.g., aquaculture products), region-specific priority chemicals based on health issues, as well as region-specific regulations for aquaculture production, should be updated. First, the prevalence of neurological disorders, particularly autism spectrum disorder (ASD), was identified in Eastern China through systematic data mining. Then, a hybrid AHP-Entropy-TOPSIS (Technique for Order Preference by Similarity to Ideal Solution) model was applied to rank the chemicals (n = 14), which might be positively associated with neurodevelopmental disorders, such as polycyclic aromatic hydrocarbons (PAHs), bisphenol A (BPA), organophosphate pesticides (OPPs), pyrethroids (PYRs), etc. Five parameters, which are odds ratios of pollutant-neurological disorder associations, urine or blood concentrations, intake via aquaculture products, publication quantities, and half-lives of the chemicals, were incorporated. The TOPSIS scores of PAHs, OPPs, BPA, phthalate acid esters (PAEs), and PYRs were higher, suggesting a considerable health risk from consuming the aquaculture products in Eastern China. Finally, dietary contribution analysis confirmed aquaculture products as a significant source for PYRs (27.2%) and PAEs (11%), followed by PAHs (6.5%), OPPs (2.5%), and BPA (0.28%) in humans. It is necessary to monitor and regulate the use and incidental input of PYRs and PAEs during the culture period, coupled with public dietary advice to minimize the health risks. Regarding PAHs and OPPs, other exposure pathways could not be ignored. For BPA, predominant exposure pathways should be identified and regulated in the future.

The published technical guidance lacks consideration of TPs in EQS derivation, which is manifested in inconsistencies between these chemicals, such as the use of additional assessment factors and the proposed application of the EQS to the sum of the measured parent and TPs rather than just the parent chemical. To resolve these inconsistencies, we have developed an evidence-driven approach to illustrate how TP considerations could be incorporated into the EQS derivation process in a repeatable and transparent manner and to utilize all the relevant and reliable data for effects and exposures. As the precedent has now been set by the European Commission that TPs may be considered in EQS derivations, we recommend that this approach be further developed and incorporated into an upcoming revision to the technical guidance to ensure that future derivations by regulators and nonregulatory environmental risk assessors and practitioners are consistent and scientifically robust.</p>","PeriodicalId":13557,"journal":{"name":"Integrated Environmental Assessment and Management","volume":" ","pages":"1357-1364"},"PeriodicalIF":3.3,"publicationDate":"2026-09-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"147837530","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"环境科学与生态学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

A proof-of-concept analysis is carried out for three case study chemicals that differ in their mode of action, usage, and data availability: Fipronil, copper, and perfluorohexanoic acid. The results indicate that each case study chemical has different predicted impacts on different taxa: Fipronil strongly affects arthropod groups, copper affects a wider range of taxa, and perfluorohexanoic acid mainly affects vertebrate species. These predicted taxa impacts are linked through logic chains to different ecosystem service provision consequences. The three case studies demonstrate the generalizability and value of the hazard, exposure, community, and ecosystem service impact assessment steps of the framework and highlight the remaining uncertainties and data gaps in its use.

This study develops a transferable geographic information system (GIS)-based framework for discriminating point- and nonpoint-source pollution in data-limited tropical basins, using the Kelani River Basin of Sri Lanka as a case study. Seventy-one surface and groundwater samples were collected across headwater, transitional, and meandering zones during dry and wet seasons, and analyzed for key physicochemical and biological parameters. The Canadian Council of Ministers of the Environment Water Quality Index (CCME-WQI) was calculated based on national and international water quality guidelines. Results classified the overall water quality as \"Marginal,\" revealing a classic spatial pattern of degradation from \"Excellent\" (WQI: 93) in pristine headwaters to \"Poor\" (WQI: 26) in the urban meandering zone, a trend observed in many urbanizing watersheds globally. Crucially, Spearman's correlation analysis identified ammonium nitrogen (NH4+-N) (R < -0.7, p < .001) and total phosphorus (TP) as the primary drivers of degradation. The persistent, seasonally consistent NH4+-N signal is a possible robust indicator of chronic raw sewage input (point-source pollution), while wet-season TP spikes implicate agricultural and urban runoff (nonpoint source pollution). The study presents substantial inferential evidence between pollution sources, demonstrating that the river's assimilative capacity is overwhelmed by continuous point-source discharges with seasonal nutrient mobilization, a critical issue in regions where sanitation infrastructure lags behind urban growth. The framework provides a replicable approach for identifying hotspots and assessing river assimilative capacity.

Fish consumption is a direct pathway for exposure, prompting extensive monitoring. In the United States and Europe, fish consumption advisories for PFAS generally focus on perfluorooctanesulfonate (PFOS), the most frequent and abundant PFAS compound reported in fish. However, PFAS analysis is costly, leading monitoring programs to frequently use composite samples (i.e., combining different fish of the same species). This financial saving comes at an analytical cost of lost information on individual variation. It is unclear how this may influence threshold-based decisions. To test this, we used a modeling approach (i.e., Monte Carlo) based on aggregated data distributions from freshwater fish species. We simulated the measurement of PFOS for individual fish compared to composite means (three, five, and 10 fish) at different levels of error structure. These values were then compared to a typical do-not-eat threshold of 200 ng•g wet mass-1 and four metrics were estimated: (i) the probability of detecting a PFOS concentration above the threshold, (ii) the maximum simulated PFOS concentration, (iii) the number of false negative samples, and (iv) the rate of false negative samples. These results show that the probability of assigning PFOS levels above or below the threshold is shifted by masking individual value contributions in a composite sample. Because true individual contaminant loads are variable, composite sampling is a more conservative metric for contaminant thresholds. The model suggested that the greater the variability, the lower the detection probability for truly contaminated samples. Our study may help to inform sampling for monitoring programs aimed at managing human exposure to PFAS.</p>","PeriodicalId":13557,"journal":{"name":"Integrated Environmental Assessment and Management","volume":" ","pages":"1579-1590"},"PeriodicalIF":3.3,"publicationDate":"2026-09-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"148198645","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"环境科学与生态学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

We assess the theoretical principles and practical applications of nematode-based ecological indicators, including the maturity index, enrichment index, structure index, and channel index, as diagnostic tools for evaluating forest soil health.
