“…The above issue has been raised, among others, by Li et al [143], Lu et al [144], Wang et al [98] and Fackelmann and Sommer [145], who pointed that ingested MP particles can scratch the gut walls causing inflammation and malnutrition, which combined with potential pathogens or opportunistic bacteria will result in a reduction in the intestine flora, leading to dysbiosis in chronically exposed organisms, which will eventually affect the immune system. The detrimental effect of ingested plastic on aquacultural organisms' health was observed in mussels, oysters, shrimps and red tilapia [146][147][148][149][150][151].…”

Aquaculture is the most rapidly growing branch of animal production. The efficiency and quality of the produced food depends on sustainable management, water quality, feed prices and the incidence of diseases. Micro- (MP < 5 mm) and nanoplastic (NP < 1000 nm) particles are among the current factors causing serious water pollution. This substance comes solely from products manufactured by humans. MP particles migrate from the terrestrial to the aquatic environment and adversely affect, especially, the health of animals and humans by being a favorable habitat and vector for microbial pathogens and opportunists. More than 30 taxa of pathogens of humans, aquacutural animals and plants, along with opportunistic bacteria, have been detected in plastic-covering biofilm to date. The mobility and durability of the substance, combined with the relatively closed conditions in aquacultural habitats and pathogens’ affinity to the material, make plastic particles a microbiological medium threatening the industry of aquaculture. For this reason, in addition to the fact of plastic accumulation in living organisms, urgent measures should be taken to reduce its influx into the environment. The phenomenon and its implications are related to the concept of one health, wherein the environment, animals and humans affect each other’s fitness.

“…While the vast literature shows that MP accumulates in living organisms [ 6 , 255 , 257 , 265 ], information regarding the harmfulness of this type of particle for people is limited ( Figure 6 ). Since mice constitute a common mammal model, one should very precisely follow research regarding the influence of this pollution on the functioning of their organisms.…”

Microplastics Derived from Food Packaging Waste—Their Origin and Health Risks

Plastics are commonly used for packaging in the food industry. The most popular thermoplastic materials that have found such applications are polyethylene (PE), polypropylene (PP), poly(ethylene terephthalate) (PET), and polystyrene (PS). Unfortunately, most plastic packaging is disposable. As a consequence, significant amounts of waste are generated, entering the environment, and undergoing degradation processes. They can occur under the influence of mechanical forces, temperature, light, chemical, and biological factors. These factors can present synergistic or antagonistic effects. As a result of their action, microplastics are formed, which can undergo further fragmentation and decomposition into small-molecule compounds. During the degradation process, various additives used at the plastics’ processing stage can also be released. Both microplastics and additives can negatively affect human and animal health. Determination of the negative consequences of microplastics on the environment and health is not possible without knowing the course of degradation processes of packaging waste and their products. In this article, we present the sources of microplastics, the causes and places of their formation, the transport of such particles, the degradation of plastics most often used in the production of packaging for food storage, the factors affecting the said process, and its effects.

“…In these investigations, micro (nano) plastics are consumed by lab-grown Danio rerio during a seven-day exposure period, and hepatotoxicity is determined using fluorescent-tagged PS micro (nano) plastics (20 µm, 5 µm, and 70 µm). When micro (nano) plastics are consumed, they can form pathogenic biofilms in the host's gut, disturbing or interacting with the gut microbiota (Li et al 2022 ). For example, Xie et al ( 2021 ) exposed Danio rerio to 10–1000 µg L −1 of MPs (8 µm, PS) and NPs (80 nm, PS) for 24 h and found that PS NPs caused more gut inflammation and gut-microbial community disturbance than MPs.…”

Plastics are an integral but largely inconspicuous part of daily human routines. The present review paper uses cross-disciplinary scientific literature to examine and assess the possible effects of nanoplastics (NPs) concerning microplastics (MPs) on human health and summarizes crucial areas for future research. Although research on the nature and consequences of MPs has seen a substantial rise, only limited studies have concentrated on the atmospheric nanosized polymeric particles. However, due to the intrinsic technological complications in separating and computing them, their existence has been difficult to determine correctly. There is a consensus that these are not only existing in the environment but can get directly released or as the outcome of weathering of larger fragments, and it is believed to be that combustion can be the tertiary source of polymeric particles. NPs can have harmful consequences on human health, and their exposure may happen via ingestion, inhalation, or absorption by the skin. The atmospheric fallout of micro (nano) plastics may be responsible for contaminating the environment. Apart from this, different drivers affect the concentration of micro (nano) plastics in every environment compartment like wind, water currents, vectors, soil erosion, run-off, etc. Their high specific surface for the sorption of organic pollutions and toxic heavy metals and possible transfer between organisms at different nutrient levels make the study of NPs an urgent priority. These NPs could potentially cause physical damage by the particles themselves and biological stress by NPs alone or by leaching additives. However, there is minimal understanding of the occurrence, distribution, abundance, and fate of NPs in the environment, partially due to the lack of suitable techniques for separating and identifying NPs from complex environmental matrices. Highlights Micro (nano) plastics generated may reach the soil, water, and atmospheric compartments. Atmospheric currents serve as a way to transport, leading to micro (nano) plastics pollution. Exposure to micro (nano) plastics may happen via ingestion, inhalation, or absorption by the skin. Nanoplastics may be environmentally more harmful than other plastic particles; the focus should be on defining the exact size range. Visual classification of micro (nano) plastics is poor in reliability and may also contribute to microplastics being misidentified. Graphical abstract
