“…Scientific evidence has uncovered that the plastic debris of various compositions, including polystyrene, polypropylene, and polyethylene, 3,4 exist ubiquitously in diverse environmental matrices, exerting negative impacts on wild organisms, including plants, 5 microalgae, 6 molluscs, 7 fishes, 8 and other food organisms. 9 Recent findings further suggest the occurrence of microplastic contamination in most human foods and drinks, 10 and an average microplastic intake rate in humans of 883 items per capita per day (up to 0.71 g per capita per day in another report). 11,12 Warnings have further advised that people enjoying take-out foods may suffer from exposure to microplastics at a level of up to 3.8 mg mL −1 , owing to the routine use of plastic containers.…”

“…The combined exposure to microplastics and antibiotics by human beings is made possible through drinking water from aquatic environments and through ingestion in the food chains. 10 exposure of microplastics and antibiotics is indeed harmful to human health, and if so, how they exert their adverse effects. In this work, we investigated the potential risk of microplastics-contaminated antibiotics to human health using a mouse model as the model mammal for human physiology.…”

“…The released microplastics can enter the human body through ingestion, inhalation, contact, and other means, posing a threat to human health. A growing number of researchers are focusing on the ingestion of microplastics by detecting the presence of microplastics in various foods, such as table salt, milk, bottled water, − tea, beer, and seafood . The unintentional ingestion of microplastics has also been confirmed by the detection of various microplastics in human stool .…”

The widespread use of plastic products leads to the ubiquity of microplastics in daily life, while the release of microplastics from long-used contact lenses has not been reported due to the limitations of conventional detection methods. Here, we established a new and rapid method to capture and count microplastics by using a high-content screening system. This method can simultaneously measure the diameter, area, and shape of each plastic particle, and the reliability and applicability of this method were verified with commercial microplastics. It is estimated that 90,698 particles of microplastics could be released from a pair of contact lenses during a year of wearing. The microplastics in the leachates were confirmed to be released from the contact lenses by scanning electron microscopy and Fourier transform infrared spectroscopy fingerprint analysis. Our study reveals an undiscovered pathway of microplastic direct exposure to humans, highlighting the urgent need to assess the potential health risks caused by eye exposure to microplastics.

“…[2][3][4][5] First studies on the release of particles from plastic containers found microplastics in drinking water and showed that polypropylene baby bottles release a considerable amount of micro-and nanoplastics upon use. [6][7][8][9][10][11] Currently the true extent of contamination with plastic particles in the environment and in consumer products, is not captured. Whereas the occurrence of microplastics is at the focus of many studies, knowledge on the occurrence of nanoplastics is still limited.…”

The true extent of plastic particle pollution is largely unknown, particularly for particles <1 µm (na-noplastics), as they are difficult to detect. Here, we expand the Nile Red (NR) staining approach often used to visualize microplastics to the quantification of nanoplastics. Using NR staining for nanoplastic quantification is largely unexplored due to the formation of fluorescent NR aggregates which cause false positive counts in single particle counting. Here, we study the number and size of the NR aggregates formed as a function of NR concentration and show that with decreasing NR concentration, the number and size of the NR aggregates drop. At nanomolar concentrations, the number of NR aggregates is low, while staining of nanoplastics at these concentrations still results in signals that are sufficiently bright for single particle detection. To challenge and verify our ap-proach, we spiked a drinking water sample with known amounts of nanoplastics. After quantifica-tion of the total amount of NR positive particles and considering NR aggregates and the added amounts of nanoplastics, we find a stable number of NR positive particles for the drinking water sample, thus verifying our approach. To demonstrate the direct applicability of our method, with-out any pre-analytical treatment, we determined the number of NR positive particles in different drinking water samples. In water obtained from plastic bottles and plastic-lined cartons, we detect-ed approximately 250 particles/nL, which is well above the level of detection of our method. In tap water, we found approximately 10 times fewer NR positive nanoparticles. Our study demonstrates that staining at nM NR concentrations combined with a careful characterization of the number of NR aggregates in solution allows for using single-particle counting for nanoplastic quantification in water samples. We foresee that this approach can contribute to filling the gap in knowledge on the abundance of nanoplastics.
