ClearPolyethylene nanoplastics affected morphological, physiological, and molecular indices in tomato (Solanum lycopersicum L.)
Polyethylene nanoplastics in soil caused significant damage to tomato plants, including reduced growth, delayed flowering, lower fruit quality, and changes in DNA methylation patterns. Even at low concentrations, the nanoplastics triggered oxidative stress and altered gene expression in the plants. These findings raise concerns about food safety because nanoplastic contamination in farm soil could reduce both the yield and nutritional quality of tomatoes and potentially other food crops.

Researchers exposed tobacco plants to polyethylene and polypropylene microplastics of different sizes and found that both types suppressed plant growth in a dose-dependent manner, with polypropylene being more toxic. The microplastics disrupted photosynthesis, triggered oxidative stress, and altered hormone signaling and defense pathways in the plants. These findings demonstrate that microplastic contamination in soil can impair crop growth at the molecular level, potentially affecting agricultural productivity.
Mechanistic insights into the size-dependent bioaccumulation and phytotoxicity of polyethylene microplastics in tomato seedlings
Researchers investigated how polyethylene microplastics of different sizes affect tomato seedlings and found that the smallest particles (1-50 micrometers) caused the most severe damage, reducing shoot weight by 42.3% and root length by 55.1%. The study revealed that microplastic uptake and toxicity are strongly size-dependent, with smaller particles more easily absorbed and translocated through plant tissues, triggering significant oxidative stress.
Impact of polyvinyl chloride (PVC) microplastic on growth, photosynthesis and nutrient uptake of Solanum lycopersicum L. (Tomato)
Adding PVC microplastics to soil reduced tomato plant growth, photosynthesis, and nutrient uptake in a dose-dependent manner, even though no visible damage appeared on the leaves. At the molecular level, the microplastics disrupted genes and proteins involved in photosynthesis and nutrient absorption. This matters for food safety because microplastics in agricultural soils could reduce crop yields and potentially enter the food supply.
