  1. 1. Applications of nanotechnology have the potential to change the entire agriculture sector and food industry from production to conservation, processing, packaging, transportation, and even waste treatment.
  2. 2. The amount of exposure to a chemical is the single most significant factor of concern. There is a level of exposure for most chemicals below which no adverse effects are likely to be observed.
  3. 4. The traditional chemical UV protection approach suffers from its poor long-term stability.
  4. 5. Chemicals vary widely in how toxic (poisonous) they are. Exposure to small amounts of highly toxic chemicals can be a greater danger than exposure to large amounts of less toxic chemicals.
