Abstract

Agrochemical pollution is a serious threat to environmental safety. Exposure to agrochemicals had deleterious health effects such as nervous system damage and cancer. Biological magnification of persistent agrochemicals also occurred. Hence, remediation approaches for agrochemical pollution must be a holistic approach, including environment and crop produces. The advent of nanotechnology helped to formulate highly efficient methods for the remediation of agrochemicals. High reactive surface area and very small packing space requirements made usage of nanoparticles as a popular agent in agrochemical remediation. Growing interests in surface-engineered nanoparticles promise complete removal of agrochemicals from the environment. Nanosorbents immobilized agrochemicals in the soil and helped microbial degradation of these compounds. However, many of the agrochemicals are persistent, and hence complete removal of these residues practice via photocatalysis. Photocatalytic degradation of persistent agrochemicals using bimetallic nanocomposites widely adopted. Large-scale environmental remediation of agrochemicals in soil, water, and agriculture products achieved via nanoparticles-based agrochemical cleaning systems such as thin-film fixed-bed reactors and nano-phytoremediation.

    While biodegradation is low efficiency [22], photocatalysis and adsorption are preferable due to high performance [19,21,23,24]. It is evident that adsorption [17,25–27] is one of the most effective techniques for lindane removal from aqueous solution. In general, novel adsorbent with high specific surface area is high performance for removal of organic micropollutants [17,28].

    For this, synthetic in-situ and/or ex-situ procedures are used, which are based on the use of metabolic pathways or biomolecules present in different living entities, which include microorganisms such as bacteria, yeasts and viruses, and higher organisms such as multicellular algae, mushrooms and plants (Shah et al., 2015; Bolade et al., 2020; González-Ballesteros and Rodríguez-Argüelles, 2020; Hou and O'Connor, 2020). Of these biosynthetic alternatives, the process based on the use of plant material is the most generalized and developed synthesis in academia, mainly due to the simple propagation of plants, and their wide phytochemical and phylogenetic diversity, the simple extraction capacity of their molecules and components through innocuous solvents, and the possibility of using different tissues, ranging from pulps and peels of fruits, leaves, roots, seeds, to flowers (see Table 2) (Anastas and Lankey, 2000; Nasrollahzadeh et al., 2015; Nath, 2015; Shah et al., 2015; Silva et al., 2015; Devatha and Thala, 2018; Ciambelli et al., 2019; Sebastian et al., 2020). In turn, small variations in the concentration of the plant extract, the amount of the precursor nanomaterial, the temperature or the pH conditions provide the ability to generate nanomaterials with different morphology, size and biological properties (Shah et al., 2015).

    Among these methods, due to the easy and cheap operation, great selectivity, less sludge production, and some other noticeable features, adsorption is recognized as a noteworthy method [100–103]. Day to day, the investigators introduce prominent materials for utilization in this field, such as layered double hydroxide hybrids [104], graphene-containing biochars or other graphene-based nanoadsorbents [105,106], bio-wastes [107,108], semiconductor photocatalyst hybrids [109,110], metal or metal oxide NPs [111,112], metal-organic frameworks [99], biopolymers and related BPNCs [113,114], and so on. Among them, ZnO NPs, as well as BPZNCs, are known as a group of photocatalysts material, which could be applied for the remediation of water [101].
