“…Allium test is suggested by UNEP, IPCS (International Programme on Chemical Safety), IPPB (International Programme on Plant Bioassay), and WHO as a typical test in cytogenetic monitoring of environmental hazards (Maity et al, 2020). The experiment is also suggested to evaluate the genotoxic effects of novel nanomaterials and considered as a substitute to animal tests (Klančnik et al, 2011).…”

Bryophyllum pinnatum is a perennial herb traditionally used in ethnomedicine. In the present report, silver nanoparticles (AgNPs) were synthesized using B. pinnatum leaf extract. BP-AgNPs were confirmed following UV-Vis spectroscopy with SPR peak at 412 nm and further characterized by FTIR, XRD, SEM-EDX, and TEM. Microscopic images confirmed the spherical shape and ~15 nm average size of nanostructures. BP-AgNPs were evaluated for photocatalytic degradation of hazardous dyes (methylene blue and Rhodamine-B) and showed their complete reduction within 100 and 110 min., respectively. BP-AgNPs have emerged as a unique SPR-based novel sensor for the detection of H2O2, which may deliver exciting prospects in clinical and industrial areas. DPPH and ABTS free radical scavenging activity were studied with respective IC50 values of 89 and 259 μg/mL. A strong intercalating interaction of CT-DNA with BP-AgNPs was investigated. Observed chromosomal abnormalities confirm the antimitotic potential of BP-AgNPs in the meristematic root tip. The cytotoxicity of BP-AgNPs against B16F10 (melanoma cell line) and A431 (squamous cell carcinoma cell line), was assessed with respective IC50 values of 59.5 and 96.61 μg/ml after 24 h of treatment. The presented green synthetic approach provides a novel and new door for environmental, industrial, and biomedical applications.

“…Due to the widespread distribution of nanoplastics in the agroecosystems, their presence in crop plants have been reported in different species 3,4,12,15,33,34 . Several methods have been developed to quantify the nanoplastics in plant samples, such as fluorescence imaging and the pyrolysis gas chromatography/mass spectrometry 35 .…”

With increasing plastic production and consumption, large amounts of polystyrene nanoplastics are accumulated in soil due to improper disposal causing pollution and deleterious effects to environment. However, little information is available about how to alleviate the adverse impacts of nanoplastics on crops. In this study, the involvement of melatonin in modulating nanoplastic uptake, translocation, and toxicity in wheat plant was investigated. The results demonstrated that exogenous melatonin application reduced the nanoplastic uptake by roots and their translocation to shoots via regulating the expression of genes associated with aquaporin, including the upregulation of the TIP2‐9, PIP2, PIP3, and PIP1.2 in leaves and TIP2‐9, PIP1‐5, PIP2, and PIP1.2 in roots. Melatonin activated the ROS scavenging system to maintain a better redox homeostasis and ameliorated the negative effects of nanoplastics on carbohydrate metabolism, hence ameliorated the plant growth and enhanced the tolerance to nanoplastics toxicity. This process was closely related to the exogenous melatonin application induced melatonin accumulation in leave. These results suggest that melatonin could alleviate the adverse effects of nanoplastics on wheat, and exogenous melatonin application might be used as a promising management strategy to sustain crop production in the nanoplastic‐polluted soils.

“…Usually plastic fragments measuring up to a size of 100 nm are considered as nanoplastics (NPs); while, plastic fragments ranging between 100 and <5 mm are considered as MPs (Haegerbaeumer, Mueller, Fueser, & Traunspurger, 2019; Koelmans, Besseling, & Shim, 2015a; Moore, 2008). The environmental source of micro/nanoplastics (M/NP) may be primary (from manufactured products) or secondary (transformation of large plastics into small fragments; Maity, Chatterjee, Guchhait, De, & Pramanick, 2019). Industrial effluents are known to have micro‐ and nano‐plastics even after passing through wastewater treatment plants (Leslie & Vethaak, 2014).…”

“…Table 1 provide some recent works regarding ecotoxicity evaluation of plastics micro/nano particles to show that the recent advances also going to the same direction. Maity et al (2019), evaluated the toxic potential of 100 nm PS micro beads on Allium cepa showing reactive oxygen species‐induced morphotoxic, cytotoxic and genotoxic effects, and effects on the cell cycle regulator cdc2 gene expression. But they did not show any deposition of PS beads inside root tissue.…”

Plastic pollution has become a global concern for ecosystem health and biodiversity conservation. Concentrations of plastics are manifold higher in the terrestrial system than the aquatic one. Micro/nanoplastics (M/NP) have the ability to alter soil enzymatic system, soil properties and also affect soil borne microorganisms and earthworms. Despite, the knowhow regarding modulatory effects of plastics are acquired from the study on aquatic system and reports on their phytotoxic potentials are limited. The presence of cell wall that could restrict M/NP invasion into plant roots might be the putative cause of this limitation. M/NP inhibit plant growth, seed germination and gene expression; and they also induce cytogenotoxicity by aggravating reactive oxygen species generation. Dynamic behavior of cell wall; the pores formed either by cell wall degrading enzymes or by plant–pathogen interactions or by mechanical injury might facilitate the entry of into roots M/NP. This review also provides a possible mechanism of large sized microplastics‐induced phytotoxicity especially for those that cannot pass through cell wall pores. As M/NP affect soil microbial community and soil parameters, it is hypothesized that they could have the potential to affect N2 fixation and research should be conducted in this direction. Reports on M/NP‐induced toxicity mainly focused only on one polymer type (polystyrene) in spite of the toxicological relevancies of other polymer types like polyethylene, polypropylene etc. So, the assessment of phytotoxic potential of M/NP should be done using other plastic polymers in real environment as they are known to intract with other environmental stressors as well as can alter the the soil–microbe–plant interaction.
