“…The results of a recent study using machine learning to predict phytotoxicity of NPs showed that the characteristic variable of plant species ranked second in relative contribution to overall model predictions (Dang et al, 2022), which is consistent with the analysis in this section. There is a large variation in the tolerance of different plants, which is reflected in studies with conventional pollutants (Kabata-Pendias, 2000).…”

Nanoplastics (NPs) are accumulating in the soil environment at a rapid rate, which may cause serious consequences for ecosystems and human health. However, environmental behaviour and toxicity of NPs in the soil-plant system remain poorly understood. This review summarizes current studies on NP-plant interactions to unravel uptake mechanisms and phytotoxicity of NPs. NPs could be taken up by plant roots and transported upwards through the xylem to all organs of the plant, even to the edible parts such as the grain, thereby threatening human health.The interaction of NPs with plants affects plant transport of water and nutrients.Besides, it induces significant oxidative stress leading to inhibition of physiological and biochemical activities such as photosynthesis, and thus adversely affects plant growth and development. In addition, the co-transport of NPs with other soil pollutants may induce the combined toxic effects. This study also discussed the potential mechanism of NP-plant interactions based on previous experience with engineered nanomaterials. Finally, a comprehensive assessment of the key challenges in each area was presented, and future perspectives are offered.

“…316 meta-analysis and ML were used to investigate the impacts of nanoplastics on terrestrial plants. 146 This study revealed that toxicity metrics most affected adverse effects, followed by plant species, nanoplastic mass concentration, and nanoplastic size. Thus, ML is valuable for the ecological risk assessment of NMs and can also extract new knowledge from the algorithm decision-making process.…”

Decades of nanotoxicology research have generated extensive and diverse data sets. However, data is not equal to information. The question is how to extract critical information buried in vast data streams. Here we show that artificial intelligence (AI) and molecular simulation play key roles in transforming nanotoxicity data into critical information, i.e., constructing the quantitative nanostructure (physicochemical properties)–toxicity relationships, and elucidating the toxicity-related molecular mechanisms. For AI and molecular simulation to realize their full impacts in this mission, several obstacles must be overcome. These include the paucity of high-quality nanomaterials (NMs) and standardized nanotoxicity data, the lack of model-friendly databases, the scarcity of specific and universal nanodescriptors, and the inability to simulate NMs at realistic spatial and temporal scales. This review provides a comprehensive and representative, but not exhaustive, summary of the current capability gaps and tools required to fill these formidable gaps. Specifically, we discuss the applications of AI and molecular simulation, which can address the large-scale data challenge for nanotoxicology research. The need for model-friendly nanotoxicity databases, powerful nanodescriptors, new modeling approaches, molecular mechanism analysis, and design of the next-generation NMs are also critically discussed. Finally, we provide a perspective on future trends and challenges.

“…MNPs have been found in honey, sugar, and all sorts of fish (Devriese et al, 2015). After plant species, mass concentration and size of nanoplastics, exposure period and pathway, negative effects are most frequently linked to toxicity measures (Dang et al, 2022). Analysis of tap, bottled, and spring waters using FTIR spectroscopy revealed the presence of microplastics in all of these water sources (Yee et al, 2021).…”

Following the advent of the Industrial Revolution, plastic pollution has been a serious environmental issue while micro-and nano-plastics have been a cynosure of researchers' attention in the twenty-first century. This is due to the improved knowledge of its ecotoxicological effects and the global pushforward towards sustainability. There is a growing concern that the increasing presence of microplastics and nanoplastics (MNPs) in aquatic habitats poses a threat to marine life, and it is predicted that nanoplastics will be just as ubiquitous as macro-and micro-plastics, but far more destructive to living organisms due to their ability to infiltrate cells. Recent research has shown that marine and freshwater biota become entangled with plastic litter, which disrupts the ecosystem. Aquatic creatures are known to absorb and deposit these new pollutants in their digestive systems, as has been documented in several studies. More recent research has also examined their co-occurrence and toxicity with other emerging contaminants, including their prevalence and effects in food, air, and soil. Using articles extracted from a six-year period from Scopus, ACS Publications and Google Scholar, this review explores the origins, fates, occurrence in the food chain, exposure routes, cellular interactions of microplastics and nano-plastics, in addition to the ecotoxicological impacts, analytical methods, and the potential remedies for combating pollution and toxicity. Ultimately, this review is a comprehensive, updated addendum to available reviews on micro-and nano-plastics.
