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.
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.
