“…There are several variants of FT-IR, from attenuated total reflection (ATR) FT-IR used for larger samples that can be physically handled, to FT-IR coupled with optical microscopy (FT-IR microspectroscopy, or micro-FT-IR). FT-IR has been used to detect and classify microplastic in all matrices indicative of human exposure, from drinking water [52][53][54][55][56][57][58][59] to the studied food groups, [60][61][62][63][64][65] to air, [66][67][68] dust, 26,28 and human tissues and biofluids. 33,34,37,40,44,[69][70][71] The other vibrational spectroscopy technique that has been applied to microplastic classification, although by less than half as much (based on a PubMed search, "microplastic and FT-IR" resulting in 1102 articles versus "microplastic and Raman" resulting in 494 articles), is Raman spectroscopy.…”

“…Probabilistic modeling of the published data results in a conservative estimated total daily median microplastic mass intake of 0.2 (0.0001–7500) μg child −1 day −1 and 0.6 (0.0003–17 000) μg adult −1 day −1 based on data for fish, mollusks, crustaceans, tap water, bottled water, salt, beer, milk, and air. 25 The contamination of dust 26 – 28 and soils 29 also highlight the potential for passive exposure, either due to deposited dust on foods and beverages, or passive ingestion from hand contact.…”

Microplastic pollution is a global issue for the environment and human health. The potential for human exposure to microplastic through drinking water, dust, food, and air raises concern, since experimental in vitro and in vivo toxicology studies suggest there is a level of hazard associated with high microplastic concentrations. However, to infer the likelihood of hazards manifesting in the human population, a robust understanding of exposure concentrations is needed. Infrared and near-infrared microspectroscopies have routinely been used to analyze microplastic in different exposure matrices (air, dust, food, and water), with technological advances coupling multivariate and machine learning algorithms to spectral data. This focal point article will highlight the application of infrared and Raman modes of spectroscopy to detect, characterize, and quantify microplastic particles, with a focus on human exposure to microplastic. Methodologies and state-of-the-art approaches will be reported and potential confounding variables and challenges in microplastic analysis discussed. The article provides an up-to-date review of the literature on microplastic exposure measurement using (near) infrared spectroscopies as an analytical tool, highlighting the recent advances in this rapidly advancing field.

“…This factor could be partially related to the lifestyle of people in the sampling region. Accordingly, it is found that urban indoors with more lavish interiors are more contaminated than rural indoors (Aslam et al 2022 ). Furthermore, with respect to the flooring, carpeted houses have recorded double the concentration of synthetic microplastics like PE, PET, polyacrylic, and PA than non-carpeted houses.…”

“…Jenner et al ( 2021 ) reported that the influence of climate on the choice of people’s clothing will also affect the characteristics of indoor microplastics. Besides, the colour of indoor microplastics also reportedly varies with the colour of clothes used in different activities like drying, washing, or sewing (Aslam et al 2022 ). Furthermore, the concentration of microplastics was noted to decrease with an increase in size (Jenner et al 2021 ; Torres-Agullo et al 2022 ; Uddin et al 2022 ).…”

Municipal wastewater has been considered as one of the largest contributors and carriers of microplastics to the aquatic environment. However, the various residential activities that generate municipal wastewater are equally significant whenever the source of microplastics in aquatic system is accounted. However, so far, only municipal wastewater has received wide attention in previous review articles. Hence, this review article is written to address this gap by highlighting, firstly, the chances of microplastics arising from the usage of personal care products (PCPs), laundry washing, face masks, and other potential sources. Thereafter, the various factors influencing the generation and intensity of indoor microplastic pollution and the evidence available on the possibility of microplastic inhalation by humans and pet animals are explained. Followed by that, the removal efficiency of microplastics observed in wastewater treatment plants, the fate of microplastics present in the effluent and biosolids, and their impact on aquatic and soil environment are explored. Furthermore, the impact of aging on the characteristics of microsized plastics has been explored. Finally, the influence of age and size of microplastics on the toxicity effects and the factors impacting the retention and accumulation of microplastics in aquatic species are reviewed. Furthermore, the prominent pathway of microplastics into the human body and the studies available on the toxicity effects observed in human cells upon exposure to microplastics of different characteristics are explored.

Analyses of air and house dust have shown that pollution of the indoor environment with microplastics could pose a fundamental hygienic problem. Indoor microplastics can result from abrasion, microplastic beads are frequently added to household products and microplastic granules can be found in artificial turf for sports activities and in synthetic admixtures in equestrian hall litter. In this context, the question arose as to what extent particulate emissions of thermoplastic materials from 3D printing should be at least partially classified as microplastics or nanoplastics. The discussion about textiles as a possible source of indoor microplastics has also been intensified. This Minireview gives an overview of the current exposure of residents to microplastics. Trends can be identified from the results and preventive measures can be derived if necessary. It is recommended that microplastics and their additives be given greater consideration in indoor environmental surveys in the future.
