Summary: This study investigated the removal of residual pesticides from pak choi using ozonated water, finding high degradation rates of pesticides and a significant reduction in microbial colonies with slight decrease in vitamin C content. The pesticide degradation mechanism followed a first + first-order kinetic model, showing ozone had a more prominent effect on malathion degradation, providing a theoretical basis for controlling agricultural pesticide residues in household applications.

Summary: This study evaluated the effects of polyethylene (PE) and polypropylene (PP) microplastics on the growth of pak choi. The results showed that the toxic effects varied among different plastic types, concentrations, and particle sizes. PP microplastics, especially those with small particle sizes, had negative impacts on the growth and antioxidant capacity of pak choi. In contrast, PE exposure improved the activities of antioxidant enzymes in pak choi, potentially counteracting the negative effects. The findings also suggested that PP and PE may indirectly inhibit pak choi growth by reducing soil aeration.

Summary: This study investigated the dynamic behaviors of newly deposited atmospheric heavy metals in the soil-pak choi system. The results showed that approximately 17-87%, 19-64%, and 43-84% of the Cu, Cd, and Pb in pak choi edible parts were contributed from the new depositions, respectively. Foliar uptake was found to be the key pathway of shoot bioaccumulation, and there were no significant differences in soil contribution between pak chois growing in 0.5-year and 1.5-year exposed soils. Additionally, soil aging resulted in a rapid decrease in the bioavailability of the deposited metals.

Summary: The study investigated the uptake and translocation of six antibiotics in pak choi, finding that fluoroquinolones had significantly higher accumulation capacity. Roots were found to be the main accumulator of antibiotics, and antibiotic translocation was associated with water transport through xylem vessels controlled by aquaporin activities and transpiration. Overall, the findings provide valuable insights for developing optimal management practices to mitigate antibiotic contamination in vegetables and ensure food safety.

Summary: This study analyzed the comprehensive effects of the neonicotinoid thiamethoxam (TMX) on pak choi. The results showed that TMX has the ability to move from the roots to the leaves of the plants, leading to a decrease in fresh weight and an increase in vitamin C, soluble sugars, and soluble solid. Metabolomic analysis revealed changes in fatty acids, purine nucleosides, flavonoids, and carbohydrates in the presence of TMX. This study raises concerns about the food safety risk associated with TMX-contaminated soil.

Summary: Biofortification of Brassica oleracea with organic and inorganic selenium resulted in stronger growth stimulation and increased levels of chlorophyll and ascorbic acid. However, the biofortification effect was lower for organic selenium compared to inorganic selenium. Supply of Chlorella increased the efficiency of biofortification with inorganic selenium but had no effect on organic selenium.

Summary: Biostimulants, specifically protein hydrolysate (PH), have a significant impact on tomato yield, quality, and elemental composition. The study found that the number of biostimulant applications and soil electrical conductivity influenced fruit yield, dry residue, Brixo, and antioxidant status of tomatoes. PH treatment showed a higher beneficial effect on fruit antioxidant status in winter compared to summer. Furthermore, PH affected the concentration of mineral elements in the tomato plants, with some elements increasing and others decreasing depending on the treatment.

Summary: The aim of this study was to investigate the profile of bioactive compounds in petals of 23 cultivars of garden roses. Flowers, especially those with red petals, were found to be a rich source of phenols, flavonoids, and anthocyanins. The chlorogenic acid content was not influenced by flower color, while white cultivars and those with pale colors had the highest level of hydroxychloroquine. Petals of all cultivars exhibited high levels of vitamin C and low levels of vitamins B. Glutathione was found in high levels in most examined roses. The presence of hydroxychloroquine in plant material was detected for the first time. Soluble oxalates content was very low. The high levels of phytochemicals in rose flowers make them excellent candidates for the food and nutraceutical industry. Some cultivars, such as 'Chorus', 'Abraham Darby', 'Graham Thomas', 'Mary Rose', 'Morning Jewel', 'Moje Hammarberg', are particularly rich sources of valuable bioactive ingredients such as phenols, flavonoids, anthocyanins, and vitamin C.

Summary: This study evaluated the effects of consortia composed of arbuscular mycorrhizal fungi (AMF) and plant growth-promoting microorganisms (PGPM) on onion cultivation. The results showed that AMF can promote onion root growth and plant performance, especially in substrates rich in organic matter. Co-inoculation of AMF and PGPM can accelerate the formation of arbuscular mycorrhiza. Increased antioxidant activity and glutathione peroxidase (GPOX) activity of onion roots reflected the successful induction of plant acclimatization response.

Summary: Due to sulfur shortage in soil and increasing global population and food consumption volume, the demand for sulfur as an important nutrient is expected to rise. This model incubation study evaluates the effects of fertilizer granule applications containing sulfur, halloysite, and phosphate rock on sulfur and phosphorus content, dehydrogenase activity, and pH value of two soils with different characteristics. Advanced statistical analysis methods, such as regression modeling and multivariate grouping, were used to analyze the relationships between soil parameters and changes caused by the experimental factors. The application of fertilizer granules had limited impact on phosphorus content, dehydrogenase activity, and soil acidity.
