Microplastics (MPs) are a significant environmental concern on a global scale, as they infiltrate many ecosystems and pose risks to human health. The present study aims to examine the origins, pathways, and health impacts of microplastics (MPs), with a particular focus on their abundance in agricultural soils and their potential for contamination in the human food chain.

I microplastici (MP) rappresentano una preoccupazione ambientale significativa su scala globale, in quanto infiltrano molti ecosistemi e rappresentano rischi per la salute umana. Il presente studio mira ad esaminare le origini, le vie e gli impatti sulla salute dei microplastici (MP), con particolare attenzione alla loro abbondanza nei terreni agricoli e al loro potenziale di contaminazione nella catena alimentare umana. Questo studio conduce un esame completo dell’abbondanza e delle caratteristiche dei microplastici (MP) nel compost organico e nel fango delle acque reflue, impiegando un’analisi dei documenti di ricerca esistenti. Questo studio esamina anche gli effetti dei deputati sulle qualità del suolo, sullo sviluppo delle piante e quindi sulla salute umana. Una constatazione degna di nota è che, sebbene il fango delle acque reflue contenga una quantità importante di MP, che sono composti principalmente di fibre, frammenti e pellicole di polietilene (PE), polistirene (PS) e polipropilene (PP), c'è una mancanza di ricerca che esamina specificamente la presenza di MP nel compost. Questo divario di conoscenze sottolinea la necessità di ulteriori ricerche per comprendere appieno i meccanismi attraverso i quali i deputati provenienti dal compost entrano nella catena alimentare e le conseguenti conseguenze per la salute. L'esposizione degli esseri umani a microplastiche (MP), ha il potenziale di indurre effetti negativi sulla salute come disturbi respiratori e gastrointestinali, stress ossidativo e carcinogenesi. Questo studio sostiene una valutazione approfondita delle strategie di utilizzo delle materie plastiche e di gestione dei rifiuti nel settore agricolo, in linea con il crescente discorso che circonda le questioni di contaminazione ambientale e di salvaguardia della qualità degli alimenti.

Abstract
Microplastics (MPs) are a significant environmental concern on a global scale, as they infiltrate many ecosystems and pose risks to human health. The present study aims to examine the origins, pathways, and health impacts of microplastics (MPs), with a particular focus on their abundance in agricultural soils and their potential for contamination in the human food chain. This study conducts a comprehensive review of the abundance and characteristics of microplastics (MPs) in organic compost and sewage sludge, employing an analysis of existing research papers. This study also investigates the effects of MPs on soil qualities, plant development, and therefore, human health. A noteworthy finding is that although sewage sludge contains an important amount of MPs, which are primarily composed of fibres, fragments, and films made of Polyethylene (PE), Polystyrene (PS), and Polypropylene (PP), there is a lack of research that specifically investigates the presence of MPs in compost. This knowledge gap underscores the necessity for further research to fully understand the mechanisms by which MPs originating from compost enter the food chain and the subsequent health consequences that ensue. Exposure of humans to microplastics (MPs), has the potential to induce adverse health effects such as respiratory and gastrointestinal disorders, oxidative stress, and carcinogenesis. This study advocates for a thorough evaluation of plastic utilization and waste management strategies in the agricultural sector, in accordance with the growing discourse surrounding issues of environmental contamination and the safeguarding of food quality.File | Dimensione | Formato | |
