Abstract

We have developed a life cycle conceptual model that suggests the importance of terrestrial ecosystems as a major repository of zinc oxide, titanium oxide, and silver manufactured nanomaterials (MNMs) introduced via the land application of MNM-containing sewage sludges. We propose to investigate the transport, fate, behaviour, bioavailability, and effects of MNMs into agroecosystems under environmentally realistic scenarios

The overall objectives are to:

1. Compare the transport, fate, behaviour, bioavailability, and effects of MNMs, a- MNMs, and/or dissolved free metals/bulk oxides to organisms with key terrestrial ecosystem functions, as well as exposure pathways involving humans;

2. Determine MNM, surface modified MNM and a-MNM interactions with important biological targets and relate these interactions to physicochemical properties;

3. Validate models with information generated from experiments designed to address Objective 1 for MNMs introduced through a pilot scale Waste Water Treatment Process (WWTP) to key terrestrial ecoreceptors, including effects of MNMs on the WWTP itself;

4. Determine realistic MNM emission scenarios for Tier 1 MNMs in wastewater from the WWT pilot plant data and develop first generation Life-Cycle-Analysis-inspired Risk Assessment (LCA-RA) model components for terrestrial effects of Tier 1 MNMs and a-MNMS based on data generated in experiments designed to address Objectives 1-3; and

5. Provide tools for in situ detection, monitoring, and characterization of pristine MNMs and a-MNMs in environmental media and biota.

Description 1)A calibrated nanosilver sediment chemistry model has been developed in the context of the risk assessment activities.

It is believed that the majority of nanomaterials eroded from the biosolid amended agroecosystems will eventually end up in the sediments. Therefore a sediment chemistry model capable of predicting the transformations of metal nanoparticles will be essential to understanding the long term risks posed by manmade nanomaterials.

2)A method was developed that allowed for isolation and characterization of Ag MNMs in soil and biosolids amended soil.

3)Methods for measuring total concentration of Ag ions released during exposure to both the pristine and sulfidized Ag-NPs have been optimized and the observed toxicity cannot be explained solely by the concentration of Ag+ after 24 h of exposure, suggesting particle-specific effects.
