Microplastics in settled dust from university indoor environments: Puerto Colombia, Colombia

Environmental Science Atmospheres 2025 6 citations

AI summary Read the abstract

Researchers surveyed settled dust in university buildings in Puerto Colombia, Colombia, and found that laboratories had the highest concentrations of microplastics. The predominant particles were fibers in the 100-500 micrometer range, composed mainly of PET, polypropylene, and polyester. The findings highlight indoor academic environments as a notable but underexplored source of microplastic exposure.

Polymers

The indoor university environment in Puerto Colombia, Colombia, with the highest mean MPs was the laboratory. Fibers (501–100 μm) and PET, PP, and polyester microparticles were predominant.

Microplastics suspended in dust from different indoor environments in Barranquilla, Colombia: Predominant microparticles?

AI summary Read the abstract

Researchers measured microplastics in indoor dust from homes and workplaces in Barranquilla, Colombia, finding plastic fibers in every environment tested. Air-conditioned rooms and shops with synthetic materials had the highest concentrations, with polyester being the most common plastic type, and estimated daily inhalation exposure ranged widely depending on the setting -- confirming that indoor environments are a significant source of human microplastic exposure.

Microplastics in indoor deposition samples in university classrooms

AI summary Read the abstract

Researchers analyzed microplastic contamination in dust collected from university classrooms and found particles from clothing fibers, shoes, and school supplies. Most particles were polyamide and polypropylene fibers ranging from 120 to over 2,000 micrometers in size, and surface damage on the particles suggests they may be breaking down into even smaller nanoplastics over time. Since people spend most of their time indoors, this indoor microplastic exposure is an important and underappreciated route of human contact with these particles.

Exploration of microplastic concentration in indoor and outdoor air samples: Morphological, polymeric, and elemental analysis

AI summary Read the abstract

Researchers measured airborne microplastics in indoor and outdoor environments in Islamabad, Pakistan, finding that indoor air contained nearly five times more microplastics than outdoor air. Classrooms had the highest contamination at about 6 particles per cubic meter, with fibers being the most common shape and polyester (PET) the most common plastic type. These findings highlight that people are continuously inhaling microplastics, especially indoors.

Airborne microplastic contamination across diverse university indoor environments: A comprehensive ambient analysis

AI summary Read the abstract

Researchers measured airborne microplastics across different indoor spaces at a university and found that people in those buildings inhale an estimated 180 to 240 microplastic particles daily. The most common types found were nylon, PTFE, polypropylene, and polyethylene, with fragments showing rough edges from wear and tear. This study highlights that indoor air is a significant and often overlooked source of microplastic exposure for people who spend most of their time indoors.

Determination of microplastics in university interior environments

AI summary Read the abstract

This study measured airborne microplastic concentrations in indoor environments at a university, finding particles in air samples from multiple indoor settings. Results contribute to evidence that indoor air represents a significant daily source of microplastic inhalation exposure, particularly given the time people spend in closed indoor environments.
