- Cellular and Molecular Mechanisms of Micro- and Nanoplastics Driving Adverse Human Health Effects (2025) · Toxics · cited 45× · doi
Detecting and quantifying micro- and nanoplastics in tissues and environmental matrices is technically challenging due to their minute size and complex sample composition. There is a lack of standardized characterization and reporting of micro- and nanoplastics. The paper also highlights the need for chronic, low-dose models and harmonized research strategies to assess the effects of micro- and nanoplastics on human health.

The study faces challenges in establishing baseline levels of microplastic contamination in fish from the estuary due to the lack of prior research. The paper encounters difficulties in identifying and quantifying microplastics due to their small size and similarity to other particles. The study must overcome the challenge of assessing the health hazards associated with microplastic ingestion in humans.

Understanding the toxicity of microplastics is a complex task due to their physicochemical characteristics and associated additives. The transfer of microplastics and associated chemicals from the lungs into the bloodstream and/or lymphatic circulation is not well understood. There is a lack of studies investigating the inhalation of microplastics containing significant amounts of additives and/or pollutants.
