Neonicotinoids were first used commercially starting in the 1990's. Since that time they have become the most widely used insecticides in the world. This widespread use has led to concerns regarding the potential for neonicotinoids to impact human and ecological health. Currently there are gaps in our understanding of neonicotinoid reactivity in the environment that hinder our ability to assess these impacts. This project will help address these gaps through a comprehensive study of the environmental fate and transport of neonicotinoids. The specific objectives are to understand how seven important neonicotinoid insecticides move, accumulate, and/or degrade in agricultural soils, surface water, and groundwater. Results will be used to develop and validate models to predict the long-term impacts of these compounds in the environment. The research will be carried out by a collaboration of researchers and students at Jackson State University and Tennessee State University, broadening participation and the diversity of the environmental engineering workforce.Neonicotinoids have become the world's most widely used insecticides since they were first commercially used in the early 1990s. Such widespread use has led to concerns regarding the potential for neonicotinoids to impact human and ecological health. This project will use a systematic and comprehensive approach to study the environmental fate and transport of the most widely used neonicotinoids in agricultural soils. To achieve this goal, the team will 1) examine the sorption and degradation of seven globally important neonicotinoids including imidacloprid, thiamethoxam, clothianidin, dinotefuran, acetamiprid, thiacloprid, and nitenpyram in three typical agricultural soils using laboratory batch tests; 2) investigate the transport and dissipation/accumulation of these neonicotinoids in soil environments in laboratory column tests, greenhouse simulation tests, and controlled field tests with multiple plant growing cycles; 3) investigate the dissipation/accumulation of neonicotinoids in surface water and groundwater at laboratory and pilot scale; and 4) study the long-term environmental impacts of neonicotinoids using fate and transport models verified with experimental data. The scaled-up greenhouse and field test data will advance understanding of the behavior of neonicotinoids in the environment at a level of breadth and depth necessary to verify the fate and transport simulation model. This model will allow the prediction of the long-term environmental impacts of the use of neonicotinoids.This award reflects NSF's statutory mission and has been deemed worthy of support through evaluation using the Foundation's intellectual merit and broader impacts review criteria.

新烟碱类杀虫剂于 20 世纪 90 年代首次投入商业使用。从那时起，它们已成为世界上使用最广泛的杀虫剂。这种广泛使用引起了人们对新烟碱类杀虫剂可能影响人类和生态健康的担忧。目前，我们对环境中新烟碱类杀虫剂反应性的理解存在差距，这阻碍了我们评估这些影响的能力。该项目将通过对新烟碱类杀虫剂的环境归宿和迁移的全面研究来帮助解决这些差距。具体目标是了解七种重要的新烟碱类杀虫剂如何在农业土壤、地表水和地下水中移动、积累和/或降解。结果将用于开发和验证模型，以预测这些化合物对环境的长期影响。该研究将由杰克逊州立大学和田纳西州立大学的研究人员和学生合作进行，扩大环境工程人员的参与和多样性。自从新烟碱类杀虫剂首次在商业上使用以来，它已成为世界上使用最广泛的杀虫剂。 20世纪90年代初。如此广泛的使用引起了人们对新烟碱类杀虫剂可能影响人类和生态健康的担忧。 该项目将采用系统、全面的方法来研究农业土壤中最广泛使用的新烟碱类杀虫剂的环境归趋和迁移。为了实现这一目标，该团队将1）使用实验室批量测试检查三种典型农业土壤中七种全球重要的新烟碱类杀虫剂的吸附和降解情况，包括吡虫啉、噻虫嗪、噻虫胺、呋虫胺、啶虫脒、噻虫啉和烯啶虫胺； 2）通过实验室柱试验、温室模拟试验和多个植物生长周期的对照田间试验研究这些新烟碱类杀虫剂在土壤环境中的运输和消散/积累； 3) 在实验室和中试规模上研究地表水和地下水中新烟碱类杀虫剂的消散/积累情况； 4) 使用经实验数据验证的归宿和运输模型研究新烟碱类杀虫剂对环境的长期影响。扩大的温室和现场测试数据将在验证归宿和运输模拟模型所需的广度和深度上促进对环境中新烟碱类杀虫剂行为的了解。该模型将允许预测使用新烟碱类杀虫剂对环境的长期影响。该奖项反映了 NSF 的法定使命，并通过使用基金会的智力价值和更广泛的影响审查标准进行评估，被认为值得支持。
