“…In this study, both the liquid phase and the GT-adsorbed DOM might have interacted with the NPs. Quantum chemical computations are widely used to calculate the interactions between NPs and organic matter. − Various DOM species were derived from agricultural organic inputs. Although the quantum chemical calculations of the representative NPs–DOM systems cannot encompass all DOM species, they do provide a theoretical basis.…”

The transport of nanoplastics (NPs) through porous media is influenced by dissolved organic matter (DOM) released from agricultural organic inputs. Here, cotransport of NPs with three types of DOM (biochar DOM (BC DOM ), wheat straw DOM (WS DOM ), and swine manure DOM (SM DOM )) was investigated in saturated goethite (GT)coated sand columns. The results showed that codeposition of 50 nm NPs (50NPs) with DOM occurred due to the formation of a GT− DOM−50NPs complex, while DOM loaded on GT-coated sand and 400 nm NPs (400NPs) aided 400NPs transport due to electrostatic repulsion. According to the quantum chemical calculation, humic acid and cellulose played a significant role in 50NPs retardation. Owing to its high concentration, moderate humification index (HIX), and cellulose content, SM DOM exhibited the highest retardation of 50NPs transport and promoting effect on 400NPs transport. Owing to a high HIX, the effect of BC DOM on the mobility of 400NPs was higher than that of WS DOM . However, high cellulose content in WS DOM caused it to exhibit a 50NPs retardation ability that was similar to that of BC DOM . Our results highlight the particle size selectivity and significant influence of DOM type on the transport of NPs and elucidate their quantum and colloidal chemical-interface mechanisms in a typical agricultural environment.

“…The wheat under the exposure of DBP showed a decrease in the dry weight ( Gao et al, 2016 ). Due to the adverse effects of phthalates on germination as reported in several studies, the growth and development of barley plants might be affected because seed germination determines the subsequent growth quality of the plant ( Gao et al, 2021 ). Thus, a reduction in biomass of barley plants could be caused by DBP accumulation that disturbed the normal seed germination and subsequent developmental processes.…”

“…Thus, the key cue behind phytotoxic responses induced by DBP was its accumulation and translocation that have incremented the ROS generation in barley. The aggravation in ROS level disturbed cellular homeostasis and wielded oxidative stress ( Sharma & Kaur, 2019 ; Gao et al, 2021 ). The oxidative stress exerted several physiological and metabolic perturbations in barley plants.…”

Background DBP is one of the most commonly used plasticizers for imparting desirable properties to polymers. The introduction of phthalates is reported to have occurred in the late 1920s, and there has been a significant rise in their release into the environment in past decades due to a lack of covalent bonding with the parent matrix. Because of their numerous applications in day-to-day life, phthalates have become ubiquitous and also classified as endocrine disruptors. Hence, several studies have been conducted to investigate the phthalate-mediated toxicities in animals; however, plants have not been explored to the same amount. Methods Therefore, in the present study, the accumulation and translocation along with morpho-physiological perturbations in barley plants after 15, 30, 60, and 120 days of exposure to di-n-butyl phthalate (DBP) are investigated using standard protocols. Results The maximal accumulation and translocation of DBP in the roots and shoots of barley plants was observed after 60 days of exposure. The exposure of DBP from 15 to 120 days was recorded to decline all the morphological indices (i.e., dry weight, net primary productivity, seed number per spike, and seed weight) of barley plants. The pigments content declined under DBP treatment for all exposure durations except 120 days exposure. Carbohydrate content increased after 15–30 days of exposure afterward it was observed to be decreased under 60 and 120 days of exposure. The protein content was declined in DBP stressed plants for 15–120 days. Proline content was increased in all exposure durations and maximal percent increase was recorded in 120 days of exposure. MDA content showed an increase at earlier exposure durations then followed by a decline in long-term exposure. Hydrogen peroxide content increased at all exposure durations. There were significant alterations observed in the activities of all antioxidative enzymes in comparison to the control. Furthermore, DBP stressed plants after 60 days were analyzed for the macromolecular variations using Fourier transform infrared spectroscopy (FTIR). Conclusion Thus, the outcomes of the current work provide an appraisal of phthalates’ uptake and translocation mediated phytotoxic responses in barley plants. These observations can help in developing genetically modified edible plants that are resistant to phthalates uptake, thereby ensuring food security.

“…Most of these techniques are focused on a physical type (non-destructive) determination; that is, the composition of the microplastic of the polymer that was separated from the sample by different analytical procedures is visualized. Different authors referenced in Table 1 report similar techniques and reagents for separating the microplastics from the samples, where among the most used reagents are dilute acids and bases (HCl, HNO 3 , NaClO, KOH, NaOH), salts (NaCl), alcohols (COH 4 and C 2 OH 6 ), and hydrogen peroxide (H 2 O 2 ) among others [55][56][57][58].…”

The presence of micro and nanoplastics in the food chain constitutes an emergent multifactorial food safety and physiological stress problem, which must be approached with a strategic perspective since it affects public health when consuming products that have this pollutant, such as fish and crustaceans, fruits, and vegetables. In this review, the authors present the results by scientists from different disciplines who are dedicated to discovering their chemical constitution and origin, the contents of these microparticles in edible plants, the contamination of water-irrigated soils, the mechanisms that concentrate microplastics in these soils, methods to determine them, contamination of freshwater sources of cities, and the negative effect of nano and microplastics on various food products and their detrimental impact on the environment. Recent findings of plant uptake mechanisms complement this, but more research is needed.
