项目摘要
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.
新烟碱类化合物在20世纪90年代首次商业化使用。从那时起,它们已成为世界上使用最广泛的杀虫剂。这种广泛的使用导致了对类尼古丁影响人类和生态健康的可能性的担忧。目前,我们对环境中类烟碱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。该项目将通过全面研究类尼古丁的环境归宿和运输来帮助解决这些差距。具体目标是了解七种重要的类烟碱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。研究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。这项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,扩大了环境工程工作人员的参与和多样性。新烟碱类杀虫剂自20世纪90年代初首次商业化使用以来,已成为世界上使用最广泛的杀虫剂。这种广泛的使用导致了对类尼古丁影响人类和生态健康的可能性的担忧。 该项目将采用系统和全面的方法研究农业土壤中最广泛使用的类烟碱的环境归宿和迁移。为了实现这一目标,研究小组将:1)使用实验室批次测试,研究七种全球重要的类烟碱类化合物在三种典型农业土壤中的吸附和降解情况,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)在实验室柱试验,温室模拟试验,和多个植物生长周期的受控田间试验; 3)在实验室和中试规模上调查地表水和地下水中类烟碱的消散/积累;以及4)使用经实验数据验证的归宿和迁移模型研究类烟碱的长期环境影响。扩大的温室和田间试验数据将在验证归宿和运输模拟模型所需的广度和深度水平上促进对环境中类烟碱行为的理解。该模型将允许预测使用类尼古丁的长期环境影响。该奖项反映了NSF的法定使命,并通过使用基金会的知识价值和更广泛的影响审查标准进行评估,被认为值得支持。
