Microplastics in Indoor Environments: Contamination, Toxicity and Mitigation Strategies
AI summary Read the abstract
This review summarizes existing research on microplastics found indoors, including their sources, types, and measured concentrations in various studies. It discusses how airborne microplastic particles may enter the body through breathing or contact with eyes, associated health conditions, and methods used to detect these particles in air, along with ideas for reducing the problem.
This chapter provides a brief summary of the properties of plastics and how they can generate microplastics under different conditions. Then, microplastics are differentiated between the various types of plastic molecules distributed in outdoor environments and those that predominate indoors. In subsequent sections, the composition and morphology of microplastics found indoors and the concentrations found in different scientific studies are discussed. The pathways by which these airborne particles enter the human body are analyzed based on their size and the main diseases produced when they come into contact with body tissues like the respiratory, digestive system, or eyes. The main analytical methods that have been recently developed for the identification and quantification of microplastics in the air are then mentioned. Finally, the current information available is analyzed, along with the study's perspective and the actions that will be taken to mitigate this emerging problem.

Airborne microplastics: Occurrence, sources, fate, risks and mitigation
AI summary Read the abstract
This review compiles findings from over 140 studies on airborne microplastics, covering their sources, distribution, and health risks in both indoor and outdoor environments. Researchers found that indoor environments often have higher microplastic concentrations than outdoor air, with textiles and building materials being major sources. The study highlights growing evidence that inhaled microplastics may pose respiratory health risks and calls for standardized measurement methods.

Review of microplastics in the indoor environment: Distribution, human exposure and potential health impacts
AI summary Read the abstract
This review comprehensively analyzes microplastic contamination in indoor environments, where most people spend the majority of their time. Researchers found that indoor exposure to microplastics comes from multiple sources including dust, air, drinking water, and food, with finer particles posing the greatest concern because they can enter the bloodstream and organs. The findings suggest that indoor microplastic exposure represents a meaningful but understudied health risk that requires further research into mitigation strategies.
