“…A recent study that investigated the phytotoxicity of GenX in lettuce showed that the shoots' dry biomass remained unaffected when treated with a concentration of 100 µg L − 1 of GenX. This suggests that at this concentration, GenX does not have a signi cant adverse effect on the growth and development of lettuce plants (Wang et al 2023). These ndings suggest that the effects of GenX on plant growth and development are concentration and species-speci c.…”

GenX (hexafluoropropylene oxide dimer acid) belongs to the group of per- and poly-fluoroalkyl substance (PFAS) compounds introduced to replace perfluorooctanoic acid (PFOA), which has been phased out in industrial and consumer product formulations. While GenX has been investigated in lab animals, there is limited information available regarding its uptake and translocation in wheat and rice. This study reports on a greenhouse experiment in which wheat and rice grown under flooded and non-flooded conditions were exposed to two GenX concentrations in the soil (0.4 mg kg− 1 and 2 mg kg− 1). GenX was analysed in the soil, porewater and shoots using targeted liquid chromatography-tandem mass spectroscopy (LC-MS/MS) analysis. Extractable organic fluorine (EOF) was determined using high-resolution continuum source graphite furnace molecular absorption spectrometry (HR GFMAS). Results showed that different species took up different amounts of GenX. The GenX in rice shoots was found to be 2.34 (± 0.45) µg g− 1 and 4.11 (± 0.87) µg g− 1 under flooded and non-flooded conditions, respectively, at a low exposure level. At high exposure, the GenX concentrations in flooded and non-flooded rice shoots increased threefold to 10.4 (± 0.41) and 13.4 (± 0.72) µg g− 1, respectively. Wheat shoots showed similar concentrations and increases between low- and high-level exposure. The translocation factor was significantly higher (P = 0.013) in non-flooded rice compared to flooded rice. The GenX bioaccumulation behaviours under the same culture conditions (e.g. temperature, humidity, light, same GenX concentration in the soil) were significantly different in non-flooded and flooded rice (P < 0.001). Non-flooded rice plants displayed a higher level of GenX bioaccumulation than flooded ones. Following exposure to GenX, flooded rice plants showed a reduction in biomass (25%) compared to the control plants (P < 0.014). Our findings indicate that GenX is a bioaccumulative compound, the presence of which likely inhibits the growth of plants.

“…). Similarly, GenX uptake has been observed to have an adverse effect on lettuce even at low concentration levels (100 µg L − 1 ), which suggests that GenX could induce oxidative stress in lettuce plants (Wang et al 2023).…”

“…Studies have shown that a plant-based diet, characterized by a significant consumption of plant foods and limited consumption of animal foods, reduces weight and cardiovascular risk factors in children [12]. Although plant foods such as fruits and vegetables are healthy, some plant foods contain a significant amount of sugar, refined carbohydrate, toxins or chemicals (e.g., vegetables, rice, potatoes and refined grains) that can have negative impacts on one's health [13][14][15][16][17][18]. Food safety is a fundamental principle in obtaining plant food sources, and nanotechnology may be one of the most important approaches to achieving adequate food safety and nutritious food effectively.…”

“…The results of a study showed the transformation of Plant-Derived Medicinal Compounds such as flavonoids, in response to metallic oxide nanoparticle contamination [17]. On the other hand, the coexposure to ZnONPs and PFOA/GenX resulted in lower oxidative stress than the plants exposed to PFOA or GenX alone [18].…”

The objective of the study was to evaluate the association between adherence to plant-based dietary patterns and anthropometric indices among primary school girls in Kerman. This cross-sectional study included 330 girls aged 6–12. A reliable and validated dish-based food frequency questionnaire was used to collect dietary data. Weight, height, and mid-arm circumference were measured, and z-score charts from the World Health Organization for girls between the ages of 5 and 19 were utilized. We used Satija et al. method to calculate plant-based diet index scores. After adjusting for age and energy, participants in the higher tertile of the overall plant-based diet index (PDI) had a lower height-for-age z score (HAZ) (0.38±0.12 vs. 0.59±0.12 kg; P = 0.033). Higher unhealthful plant-based diet index (uPDI) scores were significantly associated with decreased HAZ in models 2 (p = 0.028) and 3 (p = 0.035). A higher PDI score was associated with lower odds of being underweight and overweight, respectively (Model 1: P trend = 0.007, <0.001; Model 2: P trend = 0.010, 0.001). A significant inverse association was found between healthful plant-based diet index (hPDI) scores and underweight risk in the crude and adjusted models. (Model 1: P trend = 0.021; model 2: P trend = 0.018; Model 3: P trend = 0.031). Higher uPDI scores were associated with increased odds of being overweight and obese in all three models (Model 1: p trend<0.001; Model 2: p trend<0.001; Model 3: p trend = 0.001). We concluded that children who followed a plant-based diet had lower odds of being overweight and obese. Higher scores on the hPDI were linked to a decreased risk of being underweight, while higher scores on the uPDI were associated with an increased risk of being overweight and obese. The study suggests healthy plant-based diet may benefit children’s weight and growth.
