ClearEffects of microplastics and combined pollution of polystyrene and di-n-octyl phthalate on photosynthesis of cucumber (Cucumis sativus L.)
Researchers studied how different types of microplastics and a common plastic plasticizer affect photosynthesis in cucumber plants. They found that the combination of polystyrene microplastics and the plasticizer had the most severe impact, reducing chlorophyll production and damaging the photosynthetic machinery. The study suggests that microplastic pollution in agricultural soils, especially combined with chemical additives that leach from plastics, could meaningfully impair crop growth.
Combined toxicity influence of polypropylene microplastics and di-2-ethylhexyl phthalate on physiological-biochemical characteristics of cucumber (Cucumis sativus L.)
Researchers investigated the combined effects of polypropylene microplastics and the plasticizer DEHP on cucumber seedling health. They found that microplastics alone impaired photosynthesis and cell membrane stability, while DEHP individually also caused stress responses, but the mixture of both pollutants together produced more complex effects on the plants' antioxidant defenses. The study suggests that the co-presence of microplastics and plastic additives in agricultural soil may pose compounding risks to crop development.
