“…As for other substances, the cost and consequent toxicity of the solutions should be considered before use. After the solution is added, the lower density polymer particles float to the top of the solution due to shaking and settling [ 12 , 106 , 107 ].…”

“…On land, these microplastics are deposited in soil or sediments, the sources of which are extensive. Increased concentrations of microplastics can be found, for example, near industrial zones, ports, and cities [ 12 ]. Some MPs enter the soil in connection with sludge management in wastewater treatment plants.…”

“…Microplastics have been discovered almost everywhere: in the ocean [ 8 ], fresh water [ 9 ], wastewater [ 10 ], coastal areas [ 9 , 11 ], soil [ 12 ], sediment [ 13 ], atmosphere [ 14 ], various organisms with different frequencies, feeding patterns and trophic levels [ 15 , 16 ] and in food and agricultural systems [ 17 ]. The abundance of these particles may have a potential impact on human health [ 7 ].…”

“…Related to this are complications in the preparation of comprehensive legislation, which would be based on clear procedures for the preparation, identification and evaluation of microplastics in the environment and would include primary and secondary microplastics. Currently available legislation focuses mainly on microplastics in cosmetics and therefore lacks the constraints necessary to achieve sustainable restrictions on the use of plastic products [ 12 , 25 , 26 ].…”

Plastic particles smaller than 5 mm, i.e., microplastics, have been detected in a number of environments. The number of studies on microplastics in marine environments, fresh water, wastewater, the atmosphere, and the human body are increasing along with a rise in the amounts of plastic materials introduced into the environment every year, all contributing to a range of health and environmental issues. Although the use of primary microplastics has been gradually reduced by recent legislation in many countries, new knowledge and data on these problems are needed to understand the overall lifecycle of secondary microplastics in particular. The aim of this review is to provide unified information on the pathways of microplastics into the environment, their degradation, and related legislation, with a special focus on the methods of their sampling, determination, and instrumental analysis. To deal with the health and environmental issues associated with the abundance of microplastics in the environment, researchers should focus on agreeing on a uniform methodology to determine the gravity of the problem through obtaining comparable data, thus leading to new and stricter legislation enforcing more sustainable plastic production and recycling, and hopefully contributing to reversing the trend of high amounts of microplastics worldwide.

“…Tire wear and fragmented macroplastic that reaches the atmosphere by littering cause MP emissions in agricultural soils. Furthermore, farmers who use waste sludge and manure to fertilize their crops inadvertently add the microplastic particles contained in these biosolids to their crops [ 41 , 42 ]. In an analysis of macro- and microplastics in agricultural soil, researchers discovered up to 205 macroplastic parts per hectare (ha) and 0.34 to 0.36 microplastic particles per kilogram of soil (dry weight).…”

Are Honey Bees at Risk from Microplastics?

Microplastics (MPs) are ubiquitous and persistent pollutants, and have been detected in a wide variety of media, from soils to aquatic systems. MPs, consisting primarily of polyethylene, polypropylene, and polyacrylamide polymers, have recently been found in 12% of samples of honey collected in Ecuador. Recently, MPs have also been identified in honey bees collected from apiaries in Copenhagen, Denmark, as well as nearby semiurban and rural areas. Given these documented exposures, assessment of their effects is critical for understanding the risks of MP exposure to honey bees. Exposure to polystyrene (PS)-MPs decreased diversity of the honey bee gut microbiota, followed by changes in gene expression related to oxidative damage, detoxification, and immunity. As a result, the aim of this perspective was to investigate whether wide-spread prevalence of MPs might have unintended negative effects on health and fitness of honey bees, as well as to draw the scientific community’s attention to the possible risks of MPs to the fitness of honey bees. Several research questions must be answered before MPs can be considered a potential threat to bees.
