ClearCan microplastics threaten plant productivity and fruit quality? Insights from Micro-Tom and Micro-PET/PVC
Researchers grew tomato plants in soil containing environmentally realistic levels of PET and PVC microplastics and found mixed effects on plant productivity and fruit quality. While some growth parameters were affected, the microplastics also altered the mineral content of the tomatoes. This study suggests that microplastics in agricultural soil could change the nutritional profile of the food we eat.
Phytotoxicity of polystyrene, polyethylene and polypropylene microplastics on tomato (Lycopersicon esculentum L.)
Researchers tested the effects of polystyrene, polyethylene, and polypropylene microplastics on tomato plant growth using hydroponic experiments at various concentrations. The study found that all three types of microplastics negatively affected seed germination, root growth, and plant development, with effects varying by plastic type and concentration. These findings suggest that microplastic contamination in agricultural settings could interfere with crop growth and food production.
A Combined Effect of Mixed Multi-Microplastic Types on Growth and Yield of Tomato
Researchers grew tomatoes in soil spiked with a mixture of polyethylene, polystyrene, and polypropylene microplastics and found that while the plants appeared to grow normally, the nutritional quality of the fruit changed. Microplastics significantly reduced carotenoids, flavonoids, and sugars in the tomatoes while increasing protein and certain stress-related enzymes. This suggests that even when crops look healthy, microplastics in soil could subtly reduce the nutritional value of the food we eat.

At higher concentrations, the nanoplastics inhibited mineral uptake and diminished fruit yield along with nutritional quality markers like vitamin C and lycopene. The study highlights that nanoplastic contamination in agricultural soils could pose a meaningful threat to food crop productivity and nutritional value.
Presence of High-Density Polyethylene Nanoplastics (HDPE-NPs) in Soil Can Influence the Growth Parameters of Tomato Plants (Solanum lycopersicum L.) at Various Stages of Development
Researchers grew tomato plants in soil spiked with high-density polyethylene nanoplastics at environmentally relevant concentrations, finding that the nanoplastics slowed germination, reduced root and shoot growth, and affected plant physiology at multiple developmental stages. Effects were dose-dependent and more pronounced at higher nanoplastic concentrations. As nanoplastics are now detected in agricultural soils through biosolid application and irrigation, this study raises concerns about the impact of nano-sized plastic contamination on food crop yields.
Effects of Microplastics on the Mineral Elements Absorption and Accumulation in Hydroponic Rice Seedlings (Oryza sativa L.)
Researchers exposed rice seedlings to different concentrations of polyethylene microplastics in hydroponic conditions and measured the effects on mineral nutrient absorption. They found that while microplastics did not affect shoot growth, they significantly altered the uptake and distribution of essential mineral elements in the plants. The study suggests that microplastic contamination in agricultural settings could disrupt crop nutrition even without visible growth impacts.
