In vitro modeling of the post-ingestion mobilization and bioaccessibility of pesticides sorbed to soil and house dust
(PRESENTATION) [Presented : Mar 23, 2023]
(PRESENTATION) [Presented : Mar 23, 2023]
Soils and dusts can act as sinks for semivolatile lipophilic organic compounds and children ingest relatively large amounts of both soils and dusts. Following intake, sorbed chemicals may desorb (mobilize) and become available for intestinal absorption (bioaccessible). For chemic...
A multi-scale approach for identification of potential pesticide use sites impacting vernal pool critical habitat in California
(JOURNAL) [Published : Jan 20, 2023]
(JOURNAL) [Published : Jan 20, 2023]
Spatially explicit ecological risk assessment (ERA) requires estimating the overlap between chemical and receptor distribution to evaluate the potential impacts of exposure on nontarget organisms. Pesticide use estimation at field level is prone to error due to inc...
Challenges and opportunities for using population modeling to assess risks of pesticides to threatened and endangered species
(PRESENTATION) [Presented : Nov 17, 2022]
(PRESENTATION) [Presented : Nov 17, 2022]
Although population modeling has a long history as a decision support tool in conservation and fisheries biology, its use to inform ecological risk assessments (ERA) has been limited. Advances in methodology, publication of numerous case studies, and improved guidance in model de...
Simulating the Effects of Pesticides on Honey Bee (Apis mellifera L.) Colonies with BeePop+
(JOURNAL) [Published : Jul 26, 2022]
(JOURNAL) [Published : Jul 26, 2022]
The US Environmental Protection Agency (USEPA) employs a tiered process for assessing risks of pesticides to bees. The model discussed in this paper focuses on honey bees (Apis mellifera L.). If risks to honey bees are identified at the first tier based on exposure and toxic...
