This study assessed the potential for contaminant biotransport in Michigan's Boardman River following the planned removal of the Union Street Dam and installation of FishPass, a selective fish passage facility. We quantified polychlorinated biphenyls (PCBs), mercury (Hg), and organochlorine pesticides in carcass and egg samples from migratory species including Chinook and coho salmon, migratory rainbow trout, common white and longnose sucker, lake trout, walleye, and sea lamprey. Chinook salmon exhibited the highest PCB concentrations in both carcasses and eggs, exceeding those of rainbow trout and native suckers. Similarly, Chinook salmon were predicted to deposit up to 2,200 mg of PCBs upstream under a high run size scenario-over 80 and 100 times greater than rainbow trout and native suckers. While suckers had lower individual contaminant burdens, their relatively large run sizes contributed moderately to potential contaminant biotransport compared to rainbow trout indicating an interaction between abundance and spawner contaminant burden. Stream-resident brook and brown trout in reaches open to migratory fish had higher PCBs and lower Hg concentrations than in closed reaches, likely reflecting dietary exposure to eggs and growth dilution. These results demonstrate that the potential for contaminant biotransport varies widely among migratory species and highlights the need for managers to consider both contaminant burden and run size when making fish passage decisions to balance ecological restoration with contaminant exposure risk.</p>","PeriodicalId":13557,"journal":{"name":"Integrated Environmental Assessment and Management","volume":" ","pages":""},"PeriodicalIF":3.0,"publicationDate":"2025-07-12","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144617409","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}

This potential exposure route for birds and mammals is thus part of the European risk assessment framework for pesticide risk assessment. For assessing the risk, estimated residue concentrations on crop seeds are needed, which are typically expressed as RUD (Residue-per-Unit-Dose) values. However, proposed RUD values for seeds as given in relevant EU guidance documents were often not derived from actual crop seeds and are generally based on outdated data with unclear relevance for regulatory purposes. The objective of this work was to provide reliable crop seed RUD values representative for EU conditions and modern pesticides. For this purpose, industry field study data on crop seed residue levels for various pesticides resulting from spray application to crops at late growth stages were gathered and evaluated. This new, large data set is based on 178 residue trials and provides crop-specific data for cereals, sunflower, oilseed rape and pulses.

{"title":"Four-parameter nonlinear regression and maximum achievable effect in ecotoxicology: Just visually appealing or relevant for risk assessment?","authors":"Benjamin Daniels, Udo Hommen, Monika Ratte","doi":"10.1093/inteam/vjaf085","DOIUrl":"https://doi.org/10.1093/inteam/vjaf085","url":null,"abstract":"<p><p>In ecotoxicology, ECx refers to the concentration that causes x% effect (Organisation for Economic Co-operation and Development, 2006a). This seems to be a precise definition, but is typically only clear for ECx values calculated for inhibitions of metric variables from two and three parameter regressions, as they assume that the minimum of the affected variable is zero. In contrast, some four-parameter-regression (4PR) assume that the maximum achievable effect levels off at a value of the affected variable greater than zero. As a consequence, two types of ECx can then be calculated. While the absolute ECx considers effects always as a change compared to the control level, the relative ECx is related to the maximum achievable response to a stressor. In literature and in common software such as the drc package of R, the question whether absolute or relative ECx should be calculated is not handled in a uniform way. Based on a sensitivity analysis, it is shown, that depending on the steepness of the curve and the level of the lower limit, a relative ECx from 4PR can be considerably lower than the corresponding absolute ECx. Thus, the question of whether to use absolute or relative ECx should not be left to the preference of the user or arbitrary settings of the used software, but requires consistent and binding regulatory guidance. This paper does not advocate for absolute or relative ECx from 4PR, but outlines the characteristics and consequences of each approach. The objective is to highlight the need for discussion and to provide information for an informed decision. Future guidelines should address this issue in detail to ensure consistency, clarity and transparency in data interpretation.</p>","PeriodicalId":13557,"journal":{"name":"Integrated Environmental Assessment and Management","volume":" ","pages":""},"PeriodicalIF":3.0,"publicationDate":"2025-07-04","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144560041","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}

Fish collected from Kent Lake in 2017 had high concentrations of perfluorooctane sulfonate (PFOS) in fillets, which resulted in a fish consumption advisory from the Michigan Department of Health and Human Services. In June 2018, a major source of PFOS was identified as the City of Wixom's wastewater treatment plant, which discharges treated effluent to Norton Creek and the Huron River five miles upstream of Kent Lake. An industrial facility, which has been in operation since approximately 2000, was found to be the source of high levels of PFOS to Wixom's sanitary sewer. A granular activated carbon system was installed at the facility, resulting in substantial reductions in PFOS concentrations in surface water and fish from Kent Lake. However, the PFOS decline in fish tissue reached a plateau at a level exceeding the \"Do Not Eat\" advisory threshold. This case study sought to explore the supposition that sediment is acting as an ongoing source of per- and polyfluoroalkyl substances (PFAS) to the Kent Lake food web. We sampled PFAS in biota, sediment, and water from Kent Lake and a nearby reference lake in 2021. Biota (benthos, forage fish, and predator fish) were collected from both lakes and analyzed as whole-body composites for PFAS analytes. The results, including the patterns of PFAS contamination between the water, sediment, and biota samples as well as partition coefficients and bioaccumulation factors, are consistent with PFAS in sediment acting as an ongoing source of contamination to the biota in Kent Lake. This study's results for PFOS (the predominant PFAS in Kent Lake sediment and biota) and 6:2 fluorotelomer sulfonic acid (6:2 FTS) provide additional lines of evidence that sediment acts as a source of PFAS to the aquatic food web.</p>","PeriodicalId":13557,"journal":{"name":"Integrated Environmental Assessment and Management","volume":" ","pages":"810-822"},"PeriodicalIF":3.0,"publicationDate":"2025-07-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143189130","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}

Simultaneously, the poor management and underutilization of agricultural biomass waste presents an additional environmental challenge. Converting this biomass into biochar offers a potential solution to these challenges. This study evaluated biochar impacts on soil trace element content, rice plant uptake, translocation, accumulation, and associated human health risks while identifying rice response mechanisms to biochar application. A two-season field experiment was conducted using five treatments: T1 (no biochar), T2 and T3 (10 and 20 tons of rice-husk biochar), and T4 and T5 (10 and 20 tons of longan biochar). Eight trace elements, categorized as micronutrients (Fe, Mn, Cu, Zn) and toxic elements (Cd, Pb, Co, Ni), were measured in rice roots, stems, grains, and soil. Biochar application reduced the heavy metal pollution index (HPI) by 5.9% to 11.4% for micronutrients and 2.8% to 4.4% for toxic elements compared with T1. Translocation, bioaccumulation, and phytoextraction indexes tended to increase with biochar, and the hazard index decreased by 5.1%-9.5% for micronutrients and 1.3%-8.5% for toxic elements, indicating reduced health risks. These results highlight biochar's dual role in enhancing trace element phytoextraction and reducing health risks, with a more pronounced effect on micronutrients. Rice plants responded to reduced micronutrient availability by boosting uptake while lowering toxic element absorption when HPI was high. Transforming agricultural waste into biochar for rice cultivation offers multiple benefits, promoting agricultural sustainability, environmental health, and consumer safety.</p>","PeriodicalId":13557,"journal":{"name":"Integrated Environmental Assessment and Management","volume":" ","pages":"895-909"},"PeriodicalIF":3.0,"publicationDate":"2025-07-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143390784","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}

It is entirely reasonable and appropriate for a lag in time between the development of the science and its incorporation into routine regulatory environmental protection. We openly acknowledge that this is not just a regulatory challenge and take a more holistic view of the implementation of the science that informs metal bioavailability. Implementation comprises the steps required to utilize science and knowledge to enable its practical, beneficial, and routine application in regulatory decision-making. Different regulatory jurisdictions have taken varied approaches to account for metal bioavailability. We have made specific use of frameworks that utilize limit values, such as water quality guidelines, criteria, and quality standards, to illustrate the similarities and differences in the implementation of bioavailability. Approaches taken in Europe, Canada, Australia and New Zealand, and the United States were reviewed and evaluated. Although some of these approaches or parts thereof have been successful, other aspects have been less so. In this evaluation, we have identified key commonly encountered obstacles and challenges in these approaches to the implementation of metal bioavailability. Finally, we provide an evidence-driven \"road map\" to the successful regulatory implementation of metal bioavailability in risk assessment drawn from successful components of the approaches reviewed.
