“…Deposited particles are collected by rinsing the device with ultrapure water and filtering. Some studies collect the deposited dust over a clean glass Petri dish [51,53,65,75] or in specific areas using bristle brushes and metal dustpans [57,58,73] or a vacuum cleaner [93,94]. In addition, plant leaves [86] and spider nets [54] are also used as samplers for atmospheric MPs deposition studies.…”

Micro- and nanoplastics (MNPs) are an important atmospheric aerosol constituent. However, there still needs to be a standard procedure for their sampling and size fractionation, which is an obstacle to the aggregation and critical analysis of results obtained by different research groups. This review focuses on the sampling and fractionation methodologies used for MNPs. Moreover, a streamlined, simplified methodology for sampling and fractionation is proposed.

“…Spectroscopy is a novel technique for the identification and quantification of nanoplastics [24,25]. These types of plastics may pose a risk to the terrestrial atmosphere because the small size of microparticles allows them to easily cross cellular membranes and disturb the functioning of living organisms [26]. The nature of nanoplastics is lipophilic, which may bind plastic particles with the core of lipid bilayers [25][26][27][28][29][30].…”

The nature of nanoplastics is lipophilic, which may bind plastic particles with the core of lipid bilayers [25][26][27][28][29][30]. The study showed that the nanoplastics have surpassed the epithelial membrane of fish, and microparticles get deposited into various organs, namely, the gall bladder, pancreas, and the brain [29].…”

In recent times, the existence of microplastics in the food chain has emerged as a physiological stressor and a multifactorial food safety issue, necessitating an immediate strategic perspective due to the associated human health and eco-toxicological risks. To the best of our knowledge, edible fruit crop facts have not yet been compiled, despite their presence in various food webs. Due to the risks associated with the public’s health when consuming products (e.g., fruit crops) that contain a high concentration of microplastic pollutants, a strategic approach to the emerging issue is essential. In this review, we discussed the possible sources of microplastics and their effect on horticultural crops, soil, and microorganisms; the techniques used to know the constitution of microplastics; the eco-toxicity of microplastics and their derivatives on horticultural crops; and suggested mitigation measures and public policies on control alternatives. This research aims to help environmentalists, biotechnologists, and policymakers understand the mechanism and dynamics of microplastics in soils and edible parts so that potential risks can be mitigated in advance.

“…To our best knowledge, only three studies have evaluated AMP intake through this pathway, − and they suffer from the same limitations as aforementioned and do not report the mass ingestion. Given the considerable deposition rates of AMP in indoor environments, ,− the potential ingestion of AMPs deposited on food should not be overlooked.…”

Little research exists on the magnitude, variability, and uncertainty of human exposure to airborne micro- and nanoplastics (AMNPs), despite their critical role in human exposure to MNPs. We probabilistically estimate the global intake of AMNPs through three main pathways: indoor inhalation, outdoor inhalation, and ingestion during indoor meals, for both children and adults. The median inhalation of AMPs is 1,207.7 (90% CI, 42.5–8.48 × 104) and 1,354.7 (90% CI, 47.4–9.55 × 104) N/capita/day for children and adults, respectively. The annual intake of AMPs is 13.18 mg/capita/a for children and 19.10 mg/capita/a for adults, which is approximately one-fifth and one-third of the mass of a standard stamp, assuming a consistent daily intake of medians. The majority of AMP number intake occurs through inhalation, while the ingestion of deposited AMPs during meals contributes the most in terms of mass. Furthermore, the median ANP intake through outdoor inhalation is 9,638.1 N/day (8.23 × 10–6 μg/d) and 5,410.6 N/day (4.62 × 10–6 μg/d) for children and adults, respectively, compared to 5.30 × 105 N/day (5.79 × 10–4 μg/d) and 6.00 × 105 N/day (6.55 × 10–4 μg/d) via indoor inhalation. Considering the increased toxicity of smaller MNPs, the significant number of ANPs inhaled warrants great attention. Collaborative efforts are imperative to further elucidate and combat the current MPN risks.
