摘要

本研究的目的是以聚乙烯醇 (PVOH) 18-88 为案例，评估洗涤剂薄膜中使用的水溶性非改性 PVOH 聚合物的环境归宿、生态毒性和总体安全性。以溶解有机碳作为分析终点，进行了一项 OECD 303A 废水处理厂模拟研究，以评估废水处理过程中 PVOH 18-88 的去除情况。在高原阶段，观察到生物降解产生了高水平的去除率（平均 97.4 ± 7.1，范围：88%-116%）。OECD 303A 研究定量验证了地表水是废水处理后 PVOH 18-88 的主要接收区。急性藻类、无脊椎动物和鱼类胚胎（鱼类胚胎急性毒性试验 [FET]）生态毒性研究确定了 PVOH 18-88 的 50% 致死/有效浓度 (L/EC50)。由于绒毛膜可能会影响 PVOH 18-88 的生物利用率，因此进行了绒毛膜和去绒毛膜 FET 试验。观察到 FET（绒毛膜和去绒毛膜）、无脊椎动物和藻类的 L/EC50 > 1000 mg/L。可持续未来（美国）和 REACH（欧盟）框架用于评估环境风险。在美国的评估中，使用了 "暴露和命运评估筛选工具 "来预测 10 年内单日最低流量（1Q10）地表水浓度和 10 年内连续七日最低流量（7Q10）地表水浓度，并与急性和慢性相关浓度进行比较。在欧盟评估中，采用了欧盟物质评估系统来预测当地和区域的暴露浓度，并与预测的无影响浓度进行比较。在这两项监管评估中，暴露浓度都比效应浓度低 2 个数量级。Integr Environ Assess Manag 2024;00:1-13。© 2024 作者。综合环境评估与管理》由 Wiley Periodicals LLC 代表环境毒理学与amp; 化学学会 (SETAC) 出版。

Application of standardized methods to evaluate the environmental safety of polyvinyl alcohol disposed of down the drain

The purpose of this research was to use polyvinyl alcohol (PVOH) 18-88 as a case study to evaluate the environmental fate, ecotoxicity, and overall safety profile of water-soluble, nonmodified PVOH polymers used in detergent films. An OECD 303A Wastewater Treatment Plant Simulation Study was conducted with dissolved organic carbon as the analytical endpoint to evaluate the removal of PVOH 18-88 during wastewater treatment. During the plateau phase, high levels of removal due to biodegradation were observed (average 97.4 ± 7.1, range: 88%–116%). The OECD 303A study quantitatively verified that surface water is the dominant receiving compartment for PVOH 18-88 post wastewater treatment. Acute algae, invertebrate, and fish embryo (fish embryo acute toxicity test [FET]) ecotoxicity studies quanitified the 50% lethal/effect concentration (L/EC50) for PVOH 18-88. Due to the potential for the chorion to impact PVOH 18-88 bioavailability, both chorionated and dechorionated FET tests were conducted. L/EC50 > 1000 mg/L for FET (chorionated and dechorionated), invertebrate, and algae were observed. The Sustainable Futures (US) and REACH (EU) frameworks were used to evaluate environmental risk. For the US assessment, the Exposure and Fate Assessment Screening Tool was used to predict the single day lowest flow over a 10-year period (1Q10) surface water concentration and the seven consecutive days of lowest flow over a 10-year period (7Q10) surface water concentration and compared with acute and chronic concentrations of concern. For the EU assessment, the European Union System for the Evaluation of Substances was used to predict local and regional exposure concentrations and compared to the predicted no effect concentration. For both regulatory assessments, the exposure concentrations were >2 orders of magnitude below the effect concentrations. Integr Environ Assess Manag 2024;20:1693–1705. © 2024 The Authors.

期刊介绍： Integrated Environmental Assessment and Management (IEAM) publishes the science underpinning environmental decision making and problem solving. Papers submitted to IEAM must link science and technical innovations to vexing regional or global environmental issues in one or more of the following core areas: Science-informed regulation, policy, and decision making Health and ecological risk and impact assessment Restoration and management of damaged ecosystems Sustaining ecosystems Managing large-scale environmental change Papers published in these broad fields of study are connected by an array of interdisciplinary engineering, management, and scientific themes, which collectively reflect the interconnectedness of the scientific, social, and environmental challenges facing our modern global society: Methods for environmental quality assessment; forecasting across a number of ecosystem uses and challenges (systems-based, cost-benefit, ecosystem services, etc.); measuring or predicting ecosystem change and adaptation Approaches that connect policy and management tools; harmonize national and international environmental regulation; merge human well-being with ecological management; develop and sustain the function of ecosystems; conceptualize, model and apply concepts of spatial and regional sustainability Assessment and management frameworks that incorporate conservation, life cycle, restoration, and sustainability; considerations for climate-induced adaptation, change and consequences, and vulnerability Environmental management applications using risk-based approaches; considerations for protecting and fostering biodiversity, as well as enhancement or protection of ecosystem services and resiliency.
