Grants and Contracts Details
Use of nanomaterial-based fertilizers and pesticides could greatly improve agricultural productivity and decrease the negative environmental impacts from their use. However, the safety and efficacy of these products is unknown because the relationship between the properties of manufactured nanomaterials (MNM) used in these products and their bioavailability, environmental fate, and toxicity are unknown. This project will determine how the MNM properties, applied concentration, time, and their resulting unique spatial and temporal behaviour in soils influence their uptake by important crop plants, multigenerational effects on soil organisms, bioaccumulation, biomagnification, and trophic transfer, and therefore the potential for ecological impacts or human exposures. We also develop methods to track and characterize MNMs in soil at realistic concentrations, and develop simple test guidelines for measuring solubility and surface affinity that can predict the observed fate and effects.
