It is time to name and frame the plastic particle footprint of the agri-food sector's practices and innovations
AI summary Read the abstract
This paper proposes accounting for a 'plastic particle footprint' in the agri-food sector alongside the carbon footprint, arguing that plastic use will grow further due to population increases, resource limitations, and climate change. The authors demonstrate that transparent accounting of long-term microplastic contamination could guide decisions favoring innovations that minimize irreversible soil, water, and food plastic pollution.
While plastics offer short-term benefits to the agri-food sector by increasing productivity and food safety, they are endangering these gains in the long-term. Soil, water, and food are becoming increasingly contaminated, with persistent interactive micro- and nano-plastics disturbing the functioning of the ecosystem and affecting human health. Plastic use is likely to grow further because of population increases, resource limitations, agrochemical regulations, climate change, and transitional technologies. Up to now, efforts to mitigate plastic pollution have been mainly focused on reducing the carbon footprint and managing plastic waste. This paper demonstrates that accounting for the long-term plastic particle footprint would pave the way for transparent reviews of strategies in the agri-food sector. This would enable decisions in favor of innovations that deserve to increase our plastic particulate footprint, to be accompanied by cross-sector trade-offs, putting an end to irreversible pollution that is not justified by significant improvements in human wellbeing.

Addressing the environmental sustainability of plastics used in agriculture: a multi-actor perspective
AI summary Read the abstract
Researchers synthesized scientific and policy perspectives on agriplastics — plastics used in farming, forestry, and aquaculture — finding that while these materials boost yields, inadequate end-of-life management creates pervasive soil and water contamination, and that systemic policy interventions are needed to close the sustainability gap.
Plastic Pollution: Challenges and Strategies
AI summary Read the abstract
Less than 10% of plastics are recycled annually, with the vast majority entering natural environments where nano- and microplastics accumulate across biogeochemical cycles, posing documented threats to organismal, ecosystem, and human health. The review focuses on agricultural plastics as a critical case study for why efforts to develop truly biodegradable and biobased plastics have largely failed and how they must improve to support a circular economy.
Microplastics in agricultural landscapes: assessment of environmental risks and systemic approaches to sustainable management
AI summary Read the abstract
Tiny plastic bits are building up in farm soil from sources like plastic mulch films, sewage sludge, coated fertilizers, and contaminated irrigation water — and this review pulls together existing research to map out how that pollution spreads and what risks it poses. The concern for your health: these microplastics can disrupt soil health and potentially work their way up the food chain into what we eat, though more monitoring is needed to fully understand the danger. The paper mainly argues for better tracking systems and stricter regulations (similar to EU standards) to catch this problem before it grows.
Agricultural Microplastics Pollution: From Hidden Threats to Global Food Security Towards Sustainable Strategies
AI summary Read the abstract
This comprehensive review examines agricultural microplastic pollution across the atmosphere, soil, water, and biological systems, proposing a framework linking farming-derived MP contamination to food security risks and calling for integrated approaches to manage MNPs in agricultural systems.
The measurement of food safety and security risks associated with micro- and nanoplastic pollution
AI summary Read the abstract
Researchers reviewed how micro- and nanoplastic pollution enters the human food chain through agricultural systems, raising concerns for food safety and security. They identified major gaps in our ability to assess the risks of plastic contamination in food and feed sources. The study calls for interdisciplinary approaches and better analytical methods to understand and address this growing challenge.
