Pollinators play a vital role in ecosystem health and are essential to ensuring food security. With declines in both managed and wild pollinator populations in recent years, scientists and regulators have sought answers to this problem and have explored implementing steps to protect pollinator populations now and for the future. Pesticide Risk Assessment for Pollinators focuses on the role pesticides play in impacting bee populations and looks to develop a risk assessment process, along with the data to inform that process, to better assess the potential risks that can accompany the use of pesticide products. Pesticide Risk Assessment for Pollinators opens with two chapters that provide a biological background of both Apis and non-Apis species of pollinators. Chapters then present an overview of the general regulatory risk assessment process and decision-making processes. The book then discusses the core elements of a risk assessment, including exposure estimation, laboratory testing, and field testing. The book concludes with chapters on statistical and modeling tools, and proposed additional research that may be useful in developing the ability to assess the impacts of pesticide use on pollinator populations. Summarizing the current state of the science surrounding risk assessment for Apis and non-Apis species, Pesticide Risk Assessment for Pollinators is a timely work that will be of great use to the environmental science and agricultural research communities. Assesses pesticide risk to native and managed pollinators Summarizes the state of the science in toxicity testing and risk assessment Provides valuable biological overviews of both Apis and non-Apis pollinators Develops a plausible overall risk assessment framework for regulatory decision making Looks towards a globally harmonized approach for pollinator toxicity and risk assessment

Bringing together more than thirty influential regulators, academics, and industry scientists, Ecological Models for Regulatory Risk Assessments of Pesticides: Developing a Strategy for the Future provides a coherent, science-based view on ecological modeling for regulatory risk assessments. It discusses the benefits of modeling in the context of registrations, identifies the obstacles that prevent ecological modeling being used routinely in regulatory submissions, and explores the actions needed to overcome these obstacles. The book focuses on the following issues: Uncertainties in the process of model development, such as design, analysis, documentation, and communication The availability of data and background information needed for optimal modeling The limited knowledge of modeling The lack of confidence in the outcome of ecological models and their reliability in pesticide risk assessment It also suggests future solutions to these challenges, including: A guidance document on the modeling process Case studies that show how ecological models can provide reliable ecologically relevant risk assessments Training the people who generate or evaluate results obtained by ecological models Focusing on ecological models, such as unstructured population models, stage-structured matrix models, and individual- or agent-based models, this volume helps regulatory authorities, manufacturers, and scientists assess the risk of plant protection products in nontarget organisms. Armed with this knowledge, readers will better understand the challenges of using ecological modeling in the regulatory process.

There is, therefore, a need to adequately address the uncertainties arising from time-variable exposure profiles in the aquatic risk assessment procedure for pesticides. Linking Aquatic Exposure and Effects: Risk Assessment of Pesticides provides guidance and recommendations for linking aquatic exposure and ecotoxicological effects in the environmental assessment of agricultural pesticides. Leading international scientists share their expertise in aquatic exposure assessment, aquatic ecotoxicology, and the risk assessment and management of plant protection products. The book incorporates the tools and approaches currently available for assessing the environmental risks of time-variable exposure profiles of pesticides. It also discusses the science behind these techniques. This volume covers the extrapolation techniques, including models that address the environmental fate, toxicokinetics, toxicodynamics, and ecological effects, for performing accurate aquatic environmental risk assessments of pesticides. It explains how to link aquatic exposure and effects in the risk assessment procedure for plant protection products.

Responding to the growing need for an aggressive yet conservative approach to evaluating mussel populations, Freshwater Bivalve Ecotoxicology provides a collective review of the techniques and approaches for assessing contaminant impact on freshwater ecosystems. The editors incorporate coverage of research topics and management issues from a cross-section of scientists in the field. They explore current advances in general monitoring of population responses to stressors, fundamental concepts of ecotoxicology specific to burrowing bivalves, and useful insights that offer direction and priority for resolving specific problems challenging protection and conservation efforts. This book lays the groundwork with discussions of topics such as impact assessment, toxicokinetics, biomarkers, and pollution tolerance. The authors then explore fundamental concepts surrounding responses measured in freshwater bivalves as a consequence of chemical exposures or accumulated contaminants in target organs or tissues. They highlight the difficulties encountered with the laboratory culture of these organisms for toxicity testing or other controlled experiments, and examine the use of surrogate test organisms to relate sensitivities of response and reduce pressure on already impacted fauna. The book also reviews innovative field research using in situ bivalve toxicity testing, discusses effects-oriented tissue contaminant assessment, and concludes with threefour specific laboratory or combined field/laboratory ecotoxicology studies. A summary of methods from more than 75 laboratory toxicity studies conducted with freshwater mussels, the book provides an overview of a standardized method for conducting water-only acute and chronic laboratory toxicity tests with glochidia juvenile freshwater mussels. It focuses on studies that report measured contaminant treatments, had robust experimental designs, including replication of control and contaminant treatments, and were published in the peer-reviewed literature. The resulting array of viewpoints provides a framework that can be used to establish priorities in the rehabilitation and management of freshwater ecosystems.

Ecological Impacts of Toxic Chemicals presents a comprehensive, yet readable account of the known disturbances caused by all kinds of toxic chemicals on both aquatic and terrestrial ecosystems. Topics cover the sources of toxicants, their fate and distribution through the planet, their impacts on specific ecosystems, and their remediation by natural systems. Each chapter is written by well-known specialists in those areas, for the general public, students, and even scientists from outside this field. The book intends to raise awareness of the dangers of chemical pollution in a world dominated by industry and globalization of resources. Because the problems are widespread and far reaching, it is hoped that confronting the facts may prompt better management practices at industrial, agricultural and all levels of management, from local to governmental, so as to reduce the negative impacts of chemical contaminants on our planet.
