“…Environmental plastic contamination derives from several factors, including mismanaged plastic waste, fishing nets in the sea, and different household and commercial activities, such as washing synthetic textiles, road markings, tires, marine coatings, personal care products, and plastic pellets [6,7]. In particular, after being released into the environment, plastic products undergo a degradation process caused by the action of atmospheric agents, such as waves, abrasion, UV radiation, and photo-oxidation, in combination with biological processes, which leads to the formation of microplastics (MPs) [8]. MPs range from 5 millimetres to 100 nanometres and are classified as primary or secondary based on their source of release into the environment: primary MPs are purposely manufactured at sizes <5 mm to be employed for commercial purposes (such as glitter in cosmetic products and microbeads in cleansers, scrubs, and dish scrubbing pads), while secondary MPs are generated by the previously described environmental degradation processes of larger plastic items [9,10].…”

Raman Microspectroscopy Detection and Characterisation of Microplastics in Human Breastmilk

The widespread use of plastics determines the inevitable human exposure to its by-products, including microplastics (MPs), which enter the human organism mainly by ingestion, inhalation, and dermal contact. Once internalised, MPs may pass across cell membranes and translocate to different body sites, triggering specific cellular mechanisms. Hence, the potential health impairment caused by the internalisation and accumulation of MPs is of prime concern, as confirmed by numerous studies reporting evident toxic effects in various animal models, marine organisms, and human cell lines. In this pilot single-centre observational prospective study, human breastmilk samples collected from N. 34 women were analysed by Raman Microspectroscopy, and, for the first time, MP contamination was found in 26 out of 34 samples. The detected microparticles were classified according to their shape, colour, dimensions, and chemical composition. The most abundant MPs were composed of polyethylene, polyvinyl chloride, and polypropylene, with sizes ranging from 2 to 12 µm. MP data were statistically analysed in relation to specific patients’ data (age, use of personal care products containing plastic compounds, and consumption of fish/shellfish, beverages, and food in plastic packaging), but no significant relationship was found, suggesting that the ubiquitous MP presence makes human exposure inevitable.

“…On the one hand, the previous research is aimed at the aging of plastics under UV radiation in different media, and UV radiation has a strong negative impact on the colonization of bacteria on plastics [29] . On the other hand, the contribution of microorganisms in the natural environment to the aging of plastics should not be underestimated [30] .…”

“…A second process is the chemical alteration of the surface which results in the breakage of polymer chain and in the addition of hydroxyl or other functional groups to the MP surface resulting in a decrease of the hydrophobicity (Yao et al, 2022;You et al, 2021). Similar changes may also occur with the colonization by a periphytic biofilm (Hanun et al, 2021). As more hydrophilic functional groups are added to the MP surface, hydrophobic interaction may decrease while new electrostatic interactions or hydrogen/halogen bonds may appear.…”

Over the past decade, the number of studies examining the presence and effects of microplastics in the environment has drastically increased. Works seeking to identify these particles have proven beyond doubt that microplastics constitute a generalized pollution affecting all environmental compartments, from inside air to arctic snows. Studies on their potential ecotoxicological impacts were more nuanced but many have shown deleterious effects when these microplastics were associated with persistent organic pollutants. This primer mainly focuses on POP sorption and transport by microplastics in the aquatic environment and the possible toxic effects that result from it. Indeed, the associations between microplastics and persistent organic pollutants are very common in the environment. If the mechanisms of interactions are well known, they depend on many factors and their significance in the environment can be very variable in time and space. Indeed, these interactions depend on both the plastic particle (polymer type, crystallinity, particle size, shape, specific area, and functional groups/ polarity) and the pollutant (hydrophobicity, functional groups) but also environmental factors (microorganism population, salinity/ionic strength, pH, dissolved organic matter concentration, and temperature). Changes in the interactions between pollutants and microplastics can result in pollutant release in the aquatic environment and potential toxic effects. However, apart from specific situations, the role of microplastics as local source of exogenous molecules (PAHs, PCBs, etc.) is rarely significant because the limited amounts of involved pollutants. It is much less negligible for endogenous chemicals that enter into the initial composition of the plastic (phthalates, biocides, etc.).
