{"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.

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.

Based on an investigation of water quality and biodiversity, all nutrient inputs from anthropogenic activities promoted this lake's degradation. The environmental degradation of the lake showed the absence of management institutions. Drawing on multidisciplinary research and stakeholder engagement, this study aims to: (1) analyze the trend of environmental degradation in Lake Menjer in terms of eutrophication, and (2) evaluate the current governance structures and propose strategies for enhancing collaboration among the various stakeholders. We analyzed existing policies, institutional frameworks, and community participation models to identify gaps and opportunities for improving environmental governance practices.

This study aims to evaluate the environmental quality of urban areas used for leisure and sport in Fortaleza, Brazil, a city undergoing rapid urbanization. This research addresses the critical need for understanding urban environmental conditions and their implications for public health and urban planning. Sampling was carried out across two distinct climatic seasons (wet and dry) in 2018, spanning seven weeks in each season (April-June and October-November). The assessment employed multi-indicators, including biological (fungi and bacteria), chemical (particulate matter [PM] and carbonyl compounds), and physical parameters (noise and thermal comfort). Air quality indicators showed the following ranges: PM10 levels varied between 1.12 and 55.85 μg.m-³, PM2.5 levels ranged from 0.69 to 34.43 μg.m-³, and carbonyl compounds were observed at concentrations between 0.85 and 816.37 μg.m-³. Biological indicators included fungi counts ranging from 61.0 to 735 CFUs.m-³ (colony-forming units per cubic meter) and bacterial counts between 142.0 and 2,381.5 CFUs.m-³. Physical indicators measured noise levels at 59.87 to 66.81 dBA and thermal comfort values between 25.31 and 27.18 Discomfort Index (DI). Higher concentrations of atmospheric pollution were observed during the wet season, while thermal comfort was better during the dry season. Noise levels remained relatively constant across seasons. Notably, formaldehyde concentrations at most sampling points posed a high cancer risk, exceeding limits set by regulatory agencies. Three points also presented significant health risks due to PM exposure.
