“…They destroy the tertiary structure of pectin methylesterase in carrots, which is involved in the synthesis of cell wall components, contributing to the loss of the vegetable’s crunchiness. Microplastics reduce the nutritional value of Daucus carota and pose potential risks to human health [ 187 , 188 ].…”

Root vegetables are known all over the world, but they are being less and less consumed by individuals. The main purpose of this article was to summarize the benefits, health effects, and threats associated with the consumption of carrot, celery, parsley, beetroot, radish, turnip, and horseradish. They are characterized by high nutritional value due to their richness in dietary fiber, vitamins, and minerals. One of their most important features is their high content of bioactive compounds, such as polyphenols, phenols, flavonoids, and vitamin C. These compounds are responsible for antioxidant potential. Comparison of their antioxidant effects is difficult due to the lack of standardization among methods used for their assessment. Therefore, there is a need for a reference method that would allow for correct interpretation. Moreover, root vegetables are characterized by several health-promoting effects, including the regulation of metabolic parameters (glucose level, lipid profile, and blood pressure), antioxidant potential, prebiotic function, and anti-cancer properties. However, due to the type of cultivation, root vegetables are vulnerable to contaminants from the soil, such as toxic metals (lead and cadmium), pesticides, pharmaceutical residues, microplastics, and nitrates. Regardless, the low levels of toxic substances present in root vegetables do not pose health risks to the average consumer.

“…Similarly to PS, it can enter the intercellular spaces of carrots [ 185 ]. In addition, ABS, through the small fissures from which radish lateral roots emerge, can penetrate the xylem vessels [ 188 ]. It has also been found that PS particles with a size of 100 nm affect the reduction in the root length of Raphanus sativus [ 188 ].…”

“…Raman spectroscopy analysis indicated exogenous accumulation and uptake of MPs by root vegetables such as radish has increased the concern of microplastic ingestion through food and higher amount of MPs reaching humans and is a threat to food safety and health concerns [43]. It has been revealed that MPs in aquatic animals lead to neurotoxicity in the brain so it might be possible that similar impacts can be observed in human brains [44].…”

Decades ago, microplastic presence was corroborated in aquatic ecosystem, but revelations from current studies indicate microplastics (MPs) as ubiquitous environmental concern and demonstrate our plasticized life, because of microplastic existent in food, air, water, and soil. Existence of MPs in terrestrial ecosystem is long recognized now and additionally, all the evidence that has been found for microplastic entering the farm soils indicated that they are gradually accumulating in the agricultural soil. While previous studies focused extensively on marine systems, the increasing toxicity of MPs in agricultural cultivated soils and the aspects of MPs being accumulated causing bio-toxification are being looked upon presently. They potentially damage the yield of crop plants making their roots unable to uptake water and nutrients from the soil by accumulating near the roots. MPs have already invaded the terrestrial food chain and they have been detected in excreta of livestock animals along with earthworms and crop plants. MPs are abundant in farm soil that has interacted with sewage-sludge, plastic mulching sheets, organic fertilizers, and vermicompost for a long duration. This review focuses on current evidence of microplastic accumulation in farm soil, thereby enlightening the potential damages to crop plants, soil properties, soil microbes while ultimately reaching humans via the food chain. It also covers the recent advances for soil microplastic extraction, treatment, and possible bioremediation strategies.

“…Crop cultivation itself (the formation of the root system, the collection of crops such as potatoes and carrots), dry weather (the formation of cracks through which plastics move deeper), and the action of soil organisms also contribute to the spread of microplastics to the lower layers of the soil [102]. Accumulation and migration of micro-and nanoplastics was observed in a laboratory experiment with radish (Raphanus sativus) where acrylonitrile butadiene styrene powder was applied to the root system of the plant [103].…”

Currently, microplastics represent a widespread contamination found in almost every part of the environment. The plastic industry has generated waste since the 1950s, which unfortunately now counts in the millions. The largest share of plastic consumption is used to produce packaging materials, including those applied in the food industry. The versatility of plastic materials is mainly due to their lightness, flexibility, strength, and persistence. Although plastic materials are widely used due to their beneficial properties, contamination of the environment with microplastics and nanoplastics is an emerging problem worldwide. This type of contamination is endangering animal life and thus also the food chain and public health. This review summarizes the knowledge about microplastics in the food chain. The effect of microplastics on the food chain has been particularly studied in marine organisms, and research deals less with other food commodities. Therefore, based on the studied literature, we can conclude that the issue is still not sufficiently examined, and should be paid more attention to maintain the health of the population.
