Abstract

Pollinating bee dietary risk assessment for pesticide registration requires knowledge of nectar and pollen pesticide residue concentrations following different pesticide application methods to crops. The magnitude and duration of bee dietary pesticide exposures vary according to crop attractiveness to bees, physio-chemical properties, plant characteristics, application rate, method, and timing, and soil characteristics. Regulatory authorities rely on model-generated default estimates of pollinator exposure when measured food item pesticide residue data are unavailable for pesticide active ingredients. In North America, default pesticide residue estimates for pollen and nectar are imbedded in the United States Environmental Protection Agency's BeeREX model and, depending on the application method, are derived from various model approaches and data sources. Pursuing comprehensive bee-relevant data, we compiled and analyzed pesticide residue data from nectar and pollen samples collected during numerous field studies previously submitted to the United States Environmental Protection Agency, California Department of Pesticide Regulation, Canada Pesticide Regulatory Agency, and the European Food Safety Authority by pesticide product registrants. The information was compiled into a database that is accessible through an interactive Excel® user interface termed NPRUDv1. The interactive file that makes up NPRUDv1 allows the user to generate statistical estimates of pesticide residue per unit dose (RUD) values in nectar and pollen matrices for different application methods. The values can be used to calculate nectar and pollen estimated environmental concentrations (EECs) in models to assess dietary pollinator risk. The use of this database and the NPRUDv1 tool will strengthen the dietary exposure component of pollinator pesticide risk assessments by utilizing a database of field-measured pollen and nectar residue concentrations that represent pesticide use patterns in different crops. This publication describes the procedures followed to establish a globally comprehensive nectar and pollen residue database, demonstrates the use of NPRUDv1 and demonstrates its applicability to lower tier pollinator pesticide risk assessment.

全球花蜜和花粉农药残留数据库,具有计算不同农药施用方法单位剂量残留量的用户界面工具。
农药登记的传粉蜜蜂膳食风险评估需要了解不同农药施用方法对作物的花蜜和花粉农药残留浓度。蜜蜂膳食农药暴露的幅度和持续时间因作物对蜜蜂的吸引力、理化性质、植物特性、施用量、方法和时间以及土壤特性而异。当测量的食品农药残留数据无法获得农药有效成分时,监管当局依赖于模型生成的传粉媒介暴露的默认估计。在北美,花粉和花蜜的默认农药残留估计值嵌入在美国环境保护署的BeeREX模型中,并且根据应用方法,从各种模型方法和数据来源中得出。为了获得与蜜蜂相关的全面数据,我们收集并分析了农药产品注册人在多次实地研究中收集的花蜜和花粉样本中的农药残留数据,这些数据此前已提交给美国环境保护局、加州农药监管部、加拿大农药监管局和欧洲食品安全局。这些信息被编译到一个数据库中,该数据库可通过称为NPRUDv1的交互式Excel®用户界面访问。构成NPRUDv1的交互式文件允许用户对不同施用方法的花蜜和花粉基质中的每单位剂量农药残留(RUD)值进行统计估计。这些值可用于计算模型中的花蜜和花粉估计环境浓度(EECs),以评估膳食传粉者的风险。该数据库和NPRUDv1工具的使用将通过利用代表不同作物农药使用模式的田间测量花粉和花蜜残留物浓度数据库,加强传粉媒介农药风险评估的饮食暴露部分。本出版物描述了建立全球综合花蜜和花粉残留数据库所遵循的程序,演示了NPRUDv1的使用,并演示了其对较低层次传粉媒介农药风险评估的适用性。

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.
