• Effects of Stabilized Nanoparticles of Copper, Zinc, Manganese, and Iron Oxides in Low Concentrations on Lettuce (Lactuca sativa) Seed Germination: Nanotoxicants or Nanonutrients? (2016, background): “In general, CuO NPs induce formation of reactive oxygen species (ROS) which cause oxidative stress and damages on plant cells (Wu et al. 2012; Dimkpa et al. 2012; Shaw and Hossain 2013).”
• Effects of Manganese Nanoparticle Exposure on Nutrient Acquisition in Wheat (Triticum aestivum L.) (2018, background): “We also reported the shoot uptake of intact nano CuO (<50 nm particle size) from a solid matrix by wheat [34,35].”
• Interactions between nanoparticles and plants: phytotoxicity and defense mechanisms (2017, background): “Various determinants, such as size and shape, solubility and particle dissolution, metal ions released from metal and metal oxide NPs, biotransformation of NPs, light and so forth, may cause the ROS generation and phytotoxicity (Dimkpa et al. 2012; Rui et al. 2015; Zhang, Ma, et al. 2015).”
• Interactions between engineered nanomaterials and agricultural crops: implications for food safety (2014, background): “For example, chlorophyll a and b contents in Oryza sativa seedlings were significantly diminished with CeO2 NP treatment, as well as with Triticum aestivum treated with CuO and ZnO NPs (Dimkpa et al., 2012; Rico et al., 2013c).”
