About this Research Topic
Plastic pollution, albeit a well-documented environmental concern for the past few decades, is still in its infant stages of exploration regarding the impacts of human activities, especially with respect to food systems. Although international regulations encompass various aspects of the food system value chain, from drinking water to environmental quality, the understanding of contamination in these contexts is in its early phases. This special issue addresses this gap, focusing on scientific exploration within aquatic (e.g. aqua or mariculture) and terrestrial (e.g. agriculture or livestock) food production systems. Aligned with global efforts promoting circular economy value chains and goals of Zero Pollution and Farm to Fork initiatives, the issue seeks contributions highlighting best practices, global, national, or regional case studies, and research papers aimed at assessing, preventing, minimizing, remediating, eliminating, and controlling micro and nanoplastic concentrations across the entire food production value chain. Additionally, we invite research on method standardization, safety procedures, and supply chain links, aiming to provide a comprehensive scientific foundation contributing to policy and global sustainable development endeavors.
This research topic invites researchers to submit original research, comprehensive or mini-reviews, and short communications focusing on the detection, reduction of plastic and microplastics across the entire food chain—from extraction and production to disposal. The scope of this research topic encompasses various topics, including but not limited to:
• Microplastic sources in food systems from agriculture and aquaculture
• Effects of plastic usage in agricultural production on soil and on crops
• Plastic usage in aquaculture and its effects on cultivated species and the surrounding environment
• Alternatives to agricultural plastics and their potential effects on soil, crops, and human health
• Contribution of wastewater sludge to the dispersion and increase of microplastic loadings in agricultural production and marine pollution
• Contamination of foods with microplastics and migration of plastic additives into food via plastic packaging
• Microplastics in processed and unprocessed foods and their potential impacts on human health
• Socioeconomic dimensions of exposure to microplastics through the food supply chain.
