A new study led by Griffith University has found micro and nanoplastics in places they shouldn't be - within the leaves and stems of wheat and tomato crops. Led by Dr Shima Ziajahromi from the Australian Rivers Institute , the study found microplastics reduced plant growth and chlorophyll content, with fibre-shaped plastics - originating from synthetic textiles - having the most effects. “These findings demonstrate that agricultural soil is not just a sink for plastics, but a pathway into the food systems – meaning they could end up on our plates," Dr Ziajahromi said. “This highlights the need for improved environmental management practices, targeted mitigation strategies, and evidence-based regulations to control plastic inputs and reduce risks to food systems and human health.”
