“…This may be related to the unsaturated long chains contained in PETO and TMPTO, which proves that the unsaturated alkyl chain can reduce the toxicity of the compound. PIS is relatively susceptible to destroying plant cells, thereby inhibiting photosynthesis . DOS, PIS, TMPTO, and PETO exhibited the greatest damage to the stems, which is consistent with previous studies .…”

“…From Figure a, there was a trend of decreasing SOD enzyme activity in the leaves of wheat seedlings. This is contrary to the increased SOD activity in the research . In the initial stages of exposure, the presence of PIS may induce an increase in the number of superoxide molecules.…”

“…Wheat seeds desire a variety of hydrolytic enzymes, which is affected by the presence of various ester oils. This also leads to the lack of nutrients necessary for the germination process of wheat seeds, which may become worse and trigger inhibition with the increased concentration . From Figure c,e, their corresponding inhibition rates also revealed a dose-dependent relationship.…”

“…Many researchers chose wheat as the experimental model organism for toxicological studies of heavy metals and organic pollutants. , Gao et al proved that two ester oils with different structures inhibited the biomass accumulation of wheat seedlings, and the higher the concentration, the more obvious the inhibition . Yang et al detected the ecotoxicological effects and potential mechanisms of environmental-related concentrations for ester oil on wheat seedlings at the individual, biochemical (reactive oxygen species (ROS)/photosynthetic pigment/antioxidant enzyme activity), and molecular levels . Here, ester oil will induce an antioxidant reaction, which further adversely affected the growth and quality of wheat seedlings.…”

Although sustainable lubricants exhibit excellent performance and eco-friendly characteristics, further research is still needed to fully understand how they affect environmental systems, particularly after mechanical servicing. Herein, five ester oils with distinct structures were applied to explore their physicochemical property, lubricating performance, and phytotoxicity in order to make a profound study on the relevant structure−activity relationship of ester lubricants. Trimethylolpropane trioleate (TMPTO) and pentaerythritol oleate (PETO) were found to have the best viscosity−temperature characteristics. The friction coefficients of PETO and TMPTO are relatively small, and the order of wear volume is pentaerythritol tetraisooctanoate (PIS) > diisooctyl sebacate (DOS) > trioctyl trimellitate (TOTM) > TMPTO > PETO. Following, for different plants, the toxicity magnitude order becomes TOTM < PETO < TMPTO < DOS < PIS (wheat, germination, stem length, and root length) and TOTM < TMPTO < PETO < DOS < PIS (Pak choi, germination, and stem length). By the biochemical level, wheat seedlings displayed an inhibition of photosynthetic pigments. Meanwhile, antioxidant enzyme activities superoxide dismutase (SOD), CAT (hydrogen peroxide enzyme), peroxidase (POD), and ascorbate peroxidase (APX) exhibited a decreasing trend. This work can provide theoretical guidance for the development of environmentally friendly and high-performance lubricants.

Chiral pesticides have the special chiral structures, so enantioselective biological effects are usually observed in living organisms. Current study used paclobutrazol as a case study and explored the enantioselective degradation and oxidative stress effect on wheat. The results demonstrated that the degradation of R‐paclobutrazol was faster than S‐paclobutrazol significantly and improved the content of MDA and O2− in wheat plants, which proved that the R‐paclobutrazol induced oxidative damage in wheat, showing selective biological effects, and S‐paclobutrazol was friendly to wheat. This study provided a theoretical basis for the selective activity of chiral pesticides and the development of chiral pesticide monomers.
