Microplastics and Associated Organic Pollutants in Indoor Environments
AI summary Read the abstract
This review pulls together what scientists currently know about microplastics floating in our indoor air and settling into household dust — and it turns out we're breathing and swallowing more of these tiny plastic particles than expected, especially in cities and near waste facilities. These particles often carry harmful chemicals like phthalates and flame retardants, and kids are exposed to higher doses than adults. The takeaway: our homes and indoor spaces are a significant, underappreciated source of plastic exposure, and more research is needed to figure out how to reduce it.
This chapter provides an up-to-date overview of microplastics (MPs) and associated pollutants in indoor environments, covering multiple aspects like characterization methods, contamination status, influencing factors, and exposure risks. Active and passive techniques collected airborne particulate and settled dust samples, followed by separation and identification processes. A combination of microscopy, spectroscopy, thermal analysis, mass spectrometry, and other advanced techniques has characterized MPs physically and chemically. Indoor MPs’ prevalence and distribution profiles vary significantly between countries and microenvironments, implying the differences in emission sources, transport mechanisms, and environmental behaviors and fates. Urban areas with high population density and extensive domestic and traffic activities have been recognized as potential sources of MPs. Elevated contamination with MPs was also reported for waste processing facilities, showing specific profiles of polymer types. Additionally, MPs are essential carriers of organic micropollutants that act as plastic monomers or additives (e.g., phthalates, bisphenols, and flame retardants). MPs and related pollutants can enter the human body mainly through ingestion and inhalation pathways, leading to adverse health effects. Exposure doses of MPs are higher in children than in adults. More research is needed to provide comprehensive insights into the occurrence, characteristics, emission sources, potential risks, and abatement strategies related to MPs and their contaminants in indoor environments, especially in emerging and developing countries.

Microplastics in Indoor Environments and Associated Health Risks
AI summary Read the abstract
This review pulls together existing research showing that the air inside your home or office likely contains more tiny plastic particles (microplastics) than the air outside, coming from everyday things like household dust, synthetic fabrics, cleaning products, and packaging. Since most of us spend the majority of our time indoors, this matters because we're likely inhaling and ingesting more of these particles than previously realized, though scientists still don't fully understand the health risks. The researchers stress that more studies are needed to pin down exact dangers and figure out how to reduce this exposure at home.
An Introduction of Airborne Microplastics in Indoor and Outdoor Environments
AI summary Read the abstract
Tiny plastic bits called microplastics are floating in the air we breathe, both indoors and outdoors, mostly from everyday human activities. This review pulls together what scientists currently know about where these particles come from, how they travel, and how we might be exposed to them. The health risks are still being studied, but understanding this exposure matters since we're breathing these particles in daily, often without realizing it.
Environmental Micro(nano)plastic Exposure and Associated Human Health Risks: A Comprehensive Review
AI summary Read the abstract
Tiny plastic particles called microplastics are showing up everywhere — including inside our bodies, with scientists detecting them in blood, liver, kidneys, and even the brain. This review of existing research found that indoor air actually has more of these particles than outdoor air (bad news for kids who spend lots of time inside), and farm soils treated with plastic mulch contain over twice as many microplastics as untreated soil. While scientists still don't fully understand how these particles harm us, their spread into our food, air, and bodies is a growing health concern worth taking seriously.
Microplastics in the indoor environment
AI summary Read the abstract
This review examines microplastic contamination in indoor environments, noting that people are continuously exposed to microplastics in household dust, air, and from flooring, furniture, and textiles. Indoor microplastic exposure is a key route of human inhalation and ingestion that has received less attention than environmental contamination.
Indoor Airborne Microplastics: Sources, Human Exposure Pathways and Health Risks
AI summary Read the abstract
This review summarizes existing research on tiny plastic particles found indoors, which come from items like clothing, carpets, paints and household goods. It describes how these particles can be breathed in and reach the lungs and bloodstream, and discusses possible health effects along with current gaps in knowledge and possible mitigation strategies.
