“…This study provided new evidence that rice accumulated more OPEs than PCBs, although PCB18 was more hydrophobic than OPEs. Some researchers reported that accumulation of organic pollutant in roots was positive correlation with their hydrophobicity (Valizadeh et al, 2021), while the translocation of organic pollutant from roots to shoots was attributed to transpiration ow channel according to its high hydrophilicity (Luo et al, 2021). The translocations of three pollutants in shoots were accordance with their hydrophilicity under the single pollutant treatments.…”

“…Recent surveys found multiple organic pollutants to coexist frequently were common in environmental and organism (Sun et al, 2023;Venier et al, 2014;Wit et al, 2020;Zheng et al, 2020). Numerous previous studies attempted to rank environmental risks of toxic organic pollutants by a component-based approach that separately evaluated the association between each pollutant bioavailability and toxicity to plants rather than their mixture effect (Hao et al, 2020;Luo et al, 2021;Venier et al, 2014;Wang et al, 2021;Zhang et al, 2017;Zhang, et al, 2021). Those studies lacked to consider the real scenarios which living organisms are exposed to multiple environmental pollutants, simultaneously, throughout their lives.…”

“…Organic pollutants are absorbed by plant roots through different mechanisms, such as transmembrane, symplastic and apoplastic ways (Wit et al, 2020), and those processes could be affected by chemical charterer of pollutants and transport proteins in cells (Liu et al, 2019;Wang et al, 2019). Organic pollutants with higher hydrophobicity may be also absorbed by transporters in root plasm membrane (Zhang et al, 2022), pollutants with low hydrophobicity were mainly absorbed and translocated by the transpiration stream (Luo et al, 2021). Proteins were associated with the accumulation of PCBs and OPEs in different parts of plants (Goto et al, 2019;Wan et al, 2017;Zhang et al, 2022).…”

Combination risk of polychlorinated biphenyls (PCBs) and organophosphate esters (OPEs) contamination to the accumulation and tolerance mechanism of plants were investigated under a series of designed hydroponic experiments. The combined organic pollutants could more significantly promote plant growth than all of single organic pollutants. The positive role of pollutants in growth could be attributed to hormesis effect according to the transcript response of hormone genes. OPEs were more liable to be accumulated than PCB18 in rice. In opposite hydrophilicity (PCB18 and TCEP) pollutants combination, the accumulations of the total pollutants and TCEP in seedlings were obviously promoted compared with the single pollutant treatments. However, in similar hydrophilicity pollutants (PCB18 and TPHP) combination, TPHP and total organic pollutant accumulations in rice were inhibited. It was worthy notice that the accumulations of PCB18 in shoots were significantly increased under the combined treatments. Transcript and bioinformation analysis of lipocalins demonstrated that their interaction with OPEs were higher than PCB18, and OsTIL could directly take part in uptake, translocation and accumulation of OPEs rather than PCB18. Tolerance mechanism in rice included antioxidative enzymes and lipocalins cooperatively resisted pollutants’ oxidative stress. Therefore, the combined organic pollutants could induce high risk to food safety according this study.

“…OPEs are readily discharged into the environment because they are added as additives rather than chemically bound to the final product (Leisewitz et al, 2001). Relatively high concentrations of OPEs have recently been found in indoor and outdoor air, surface and ground water, sediment, and soil (Shi et al, 2016;Yadav et al, 2017;Luo et al, 2018a;Ji et al, 2019;Luo et al, 2021a). However, studies on the vertical distribution and historical contamination trends of OPEs in sediments have received little attention.…”

The historical trends and inventory of organophosphate esters (OPEs) were investigated based on depth profiles of OPEs in sediment core collected from the tidal flat of the Liao River estuary in northeastern China. The concentration of ∑13OPEs in sediment core has increased continuously since records began, reaching a peak of 10.8 ng g-1 dry weight (dw) in the 1960s, then began to decline and fall to a low of 3.91 ng g-1 dw in the 1980s, before rising again and increasing to 20.4 ng g-1 dw in the 2000s. After a brief decline, It started to increase again and reached a peak of 27.0 ng g-1 dw in 2018. Tributyl-n-phosphate was found in each layer of the sediment core, accounting for 31.9 - 100% of ∑13OPEs. The fluxes of OPEs ranged from 46.5 to 105 ng cm-2 y-1 in the sediment layers deposited between 2007 and 2018. The inventory of OPEs in the sediment core was estimated to be 1541 ng cm-2. This work reports for the first time the historical contamination trends of OPEs in Chinese sediments, which is important for assessing the environmental risk of OPEs.

N‐(1,3‐dimethylbutyl)‐N′‐phenyl‐p‐phenylenediamine (6PPD) and N‐(1,3‐Dimethylbutyl)‐N′‐phenyl‐p‐phenylenediamine‐quinone (6PPD‐Q) are the derivatives of tire wear particles (TWPs) that can enter the agricultural environment. Their negative consequences on the agricultural environment remain unknown, particularly their toxic effects on edible plants. In this experiment, the toxicity of different concentrations of 6PPD and 6PPD‐Q on pakchoi (Brassica rapa L. ssp. chinensis) was explored by hydroponics. The results revealed that seed germination was inhibited by 6PPD and 6PPD‐Q to various degrees. However, we observed an increase in the fresh weight of pakchoi seedling. Environmental concentration (1 μg L−1) of 6PPD and 6PPD‐Q significantly increased ROS levels and caused changes in antioxidant enzyme activities. The MDA content of pakchoi was significantly elevated under 6PPD‐Q treatment, indicating severe oxidative damage. These results demonstrated the phytotoxicity induced by 6PPD and 6PPD‐Q, which is of great significance for assessing their potential ecological risks in the environment.
