Uptake And Accumulation Of Engineered Nanomaterials By Agricultural Crops And Associated Risks In The Environment And Food Safety, Yingqing Deng
Doctoral Dissertations
Engineered nanomaterials (ENMs) are being discharged into the environment and to agricultural fields, with unknown impacts on crop species. This study focused on the bioaccumulation of engineered nanomaterials into crops and the associated impact on plant growth and plant uptake of secondary contaminant. Investigations into the interactions between nanomaterials and agricultural plants will provide a more developed understanding of nanomaterials implications in the environment; in addition, evaluations of the risks associated with plant-nanomaterials interactions will provide guidelines for safe use of nanomaterials in agriculture. In the screening study on phytotoxicity, carbon-based nanoparticles (NPs) including C60, MWCNTs, NH2 …

Doctoral Dissertations
Bioenergy is renewable energy made of materials derived from biological, non-fossil sources. In addition to the benefits of utilizing an energy source that is renewable, bioenergy is being researched for its potential positive impact on climate change mitigation, job creation, and regional energy security. It has also been studied to investigate possible challenges related to indirect and direct land-use change and food security. Bioenergy sustainability assessment provides a method to identify, quantify, and interpret indicators, or metrics, of bioenergy sustainability in order to study trade-offs between environmental, social, and economic aspects of bioenergy production and use. Assessment is crucial to …
