Abstract

Rapid progress and broad applications of nanotechnology has resulted into a considerable increase in the number of engineered-nanomaterials that are inevitably entering in the environment and agriculture fields and have become a critical environmental threat. The production of engineered nanomaterials is increasing very rapidly due to their wide applications. The predicted global market value for nanomaterials would be about 11.3 billion USD by 2022 and almost 9–37% of engineered nanomaterials are directly or indirectly emitted into the atmosphere. It is apparent that due to technological upgradation, unsustainable use products and anthropogenic activities, contamination of agricultural soil with engineered nanomaterials has recently become a severe problem because it may lead to some unidentified issues related to food safety and quality. Finding a sustainable and ecological benign approach is a major challenge to contest engineered contamination of agriculture soil as well as crops grown there.

In spite of availability of huge toxicological data on engineered nanomaterials, systematic studies on impact of engineered nanomaterials and the underlying mechanism of their toxicity on crops are still not fully revealed. Therefore, this chapter comprehensively summarizes the current knowledge on exposure pathway of engineered nanomaterials, to agricultural soil, their interaction with crops and phytotoxicity at morphological, physiological and molecular level. Eventually, it highlights the mechanisms of engineered nanomaterials detoxification in crop plants in order to increase tolerance and sustainability. A clear understanding of engineered nanomaterials impacts on crops will help in optimizing their application in agriculture to improve crop production and to meet unforeseen demand of food in safe and sustainable way. The present chapter would provide a comprehensive current knowledge on the issue and a clear understanding of engineered nanomaterials impacts on crops plants.
