The study investigates the accumulation and translocation of di-n-butyl phthalate (DBP) in barley plants after 15, 30, 60, and 120 days of exposure. Results from the study revealed that DBP accumulates and translocates in the roots and shoots after 60 days, with all morphological indices declining. Pigment content declines, carbohydrates increase after 15–30 days, and protein content declines for 15–120 days. Proline content increases in all exposure durations, with a maximum increase in 120 days. DBP-stressed plants were analysed for macromolecular variations using Fourier transform infrared spectroscopy (FTIR). Outcomes from the study provide an appraisal of phthalates’ uptake and translocation-mediated phytotoxic responses in barley plants. These observations help in developing genetically modified edible plants that are resistant to phthalate uptake, thereby ensuring food security.
This study investigates halogenated flame retardants (HFRs) in vegetables grown near an e-waste-contaminated site. Polybrominated diphenyl ethers (PBDEs) were the dominant HFRs, followed by novel brominated flame retardants (NBFRs) and dechlorane plus (DPs), with concentrations varying across vegetable species. The highest levels were found in Brassica oleracea var. capitata. Root concentration factors decreased with increasing[…]
This study examines the uptake and health risks of novel brominated flame retardants (NBFRs) in soil-vegetable systems. Seven NBFRs were analysed in greenhouse and conventional tomatoes and cucumbers. Greenhouse vegetables showed higher concentrations of Σ7 NBFRs (2.8–3.8 ng g⁻¹ dw) compared to conventional ones (1.1–1.7 ng g⁻¹ dw). Root and fruit bioaccumulation factors (RBCFs: 0.6–6.3,[…]
This study assessed the root uptake and root-shoot translocation of seven organophosphorus flame retardants (OPFRs) and four novel brominated flame retardants (NBFRs) in hydroponic maize plants. The initial liquid concentrations of each compound were examined, with 30 μg L−1 treatments being phytotoxic due to a significant decrease in shoot dry weight. Plant-driven removal of the[…]
The study aimed to investigate the uptake pathways of phthalates (PAEs) in Chinese flowering cabbage and the effects of spraying PAE-degrading strains on PAE accumulation in vegetables. Results showed that leaves of cabbage grown in plastic greenhouses absorbed more PAEs from the air than those of outside greenhouses. PAEs were mainly stored in leaf surfaces,[…]
The study investigated the effects of polystyrene nanoparticles (MNPs) on the uptake of eight organic pollutants (OPEs) by rice seedlings. Results showed that OPEs accumulated in a concentration-dependent manner in both roots and shoots of rice seedlings. The impacts of MNPs were concentration- and size-dependent, influencing transpiration rate and antioxidant enzyme activities. Significant effects were[…]
