Airborne microplastics enter plant leaves and end up in our food
AI summary Read the abstract
Researchers identified a previously overlooked pathway by which airborne microplastics can enter crop leaves directly through foliar uptake, with implications for both ecological contamination and the presence of microplastics in the human food supply.
Evidence for a previously overlooked route for microplastics to enter crops and reach plant tissues has implications for ecology and human health. Evidence for a previously overlooked route for microplastics to enter crops and reach plant tissues has implications for ecology and human health.

Uptake of Microplastics and Their Effects on Plants
AI summary Read the abstract
Researchers reviewed accumulating evidence on microplastic uptake by terrestrial plants, finding that particles smaller than 200 nm can enter root cells and translocate to shoots, potentially disrupting photosynthesis, nutrient uptake, and growth while opening a pathway for microplastics to enter the human food chain through crops.
Microplastics in Crops
AI summary Read the abstract
Researchers reviewed how microplastics accumulate in agricultural soils and are taken up by crop plants, raising food safety concerns as these particles and their associated chemical contaminants may enter the human food supply through plant consumption.
Microplastics in Plant Species: Impacts and Ecological Perspectives
AI summary Read the abstract
This analysis examined how microplastics affect plant physiology in terrestrial ecosystems, including uptake through roots, translocation into edible tissues, disruption of photosynthesis, and alteration of soil microbial communities that plants depend on. Because many staple crops can absorb and accumulate microplastics from contaminated soil and irrigation water, agricultural microplastic pollution translates directly into human dietary exposure through fruits, vegetables, and grains.
