Microplastics (MPs) and nanoplastics (NPs) are emerging environmental contaminants that have raised increasing concern regarding their potential health effects. During pregnancy and early life, developing organisms are particularly vulnerable due to immature biological barriers and the dynamic nature of organogenesis. This review summarizes current evidence on maternal and early life exposure routes to MPs and NPs, including oral ingestion, inhalation, dermal contact, and transplacental…

The ubiquity of microplastics and nanoplastics (or microplastic and nanoplastic particles, collectively MNPs) in the modern environment has led to detection of polymer particles and polymer-associated chemicals repeatedly within human tissues and fluids, inevitably raising concern for long-term effects on organ systems, including the skeleton. Accumulated evidence over the last decade implicates MNPs and plastic-associated endocrine disrupting chemicals (EDCs), such as phthalates and bisphenols,…

The rising concentrations of anthropogenic microplastics (MPs; 1 µm to 5 mm) and nanoplastics (NPs; < 1 µm) pollution pose a global crisis, presenting a grave threat to the ecosystem and the health of living creatures within. Studies between 2024 and 2025 reported the bioaccumulation of MPs and NPs (MNPs) in several human organs. However, unlike animal and cell line studies, the relationship between MNPs exposure and carcinogenesis in humans remains unclear. To our knowledge, this is the first…

Plastics are ubiquitous in all trophic environments. Human exposures primarily occur via ingestion, inhalation, and/or injection routes. However, laboratory models of micro- and nanoplastic (MNP) particle exposures replicating the human condition remain inconsistent and uncharacterized, thus limiting study strength and compromising the reliability of results. The purpose of this study was to thoroughly optimize and characterize an established methodology for MNP rodent inhalation exposures, and…

The pervasive environmental contamination of microplastics (MPs) and nanoplastics (NPs) has raised significant public health concerns, with the respiratory tract being a critical route of exposure. While a growing body of evidence suggests adverse pulmonary effects, a comprehensive synthesis of systematic reviews (SRs) is lacking. This umbrella review systematically consolidates evidence from published SRs to evaluate the impact of MP and NP exposure on human pulmonary health. Accordingly, a…

Microplastics and nanoplastics (MPs/NPs) have emerged as pervasive and persistent environmental contaminants, prompting significant concerns about their potential risks to human health. This review provides a comprehensive synthesis of the current state of knowledge on the reproductive toxicity induced by MPs/NPs, with a particular focus on nanoplastics (NPs, <100 nm) due to their enhanced ability to cross biological barriers and induce cellular damage. Following a systematic literature search,…

Micro- and nanoplastics (MPs/NPs) have emerged as pervasive environmental contaminants with increasing implications for human health, particularly within the digestive system. This review critically examines the role of MPs/NPs as disruptors of gastrointestinal and liver homeostasis through the lens of the plastic-gut-liver axis. We synthesize current evidence on primary exposure routes-including ingestion, inhalation, dermal contact, and transplacental transfer-and highlight their intestinal…

The development of new materials that are inherently safe and sustainable has become a critical objective in the context of the green transition. This challenge is especially significant for plastics, which often contain complex mixtures of chemicals that may be released during various stages of their life cycle and that can pose risks to human health and the environment. Within this context, the Safe and Sustainable by Design (SSbD) framework was followed to support the design of an innovative…

CONCLUSION: Our results indicate low-dose PS-NPs can activate the AMPK pathway and lipophagy, thereby alleviating liver injury through a stress adaptation response under high-fat diet conditions. Our findings elucidate the context-dependent interaction between microplastics and dietary patterns in liver diseases development and provide novel insights into the health effects of microplastics.
