“…A study comparing microplastics in soils from forests, agricultural land, and suburban areas found the highest abundance of microplastics in soils close to traffic. The number of particles counted by stereomicroscope averaged over thousand particles per kilo soil, dominated by TWP (Choi et al 2020). Data from the medium-sized city of Bergen, Norway, found that TWP dominated sediments in street sweepings (Henriksen 2020).…”

We all use plastics for a variety of purposes, and the amount of plastic produced and used is increasing worldwide, now reaching over 380 million metric tons (MMT) annually. Waste management in highly populated areas is currently insufficient to prevent large amounts of municipal waste from entering the environment; currently, the estimated annual mass of mismanaged waste is 80 MMT. With time, much of the plastic litter will degrade into microplastics, and once distributed, it is essentially impossible to remove. An estimated 4.8-12.7 MMT of plastics reach the ocean every year, while terrestrial systems are expected to accumulate 4-23 times more than the ocean. Waste generation,

“…As the main process of removing POPs, microorganisms play a major role in PAE degradation in the environment under various conditions (Staples et al, 1997). As a new habitat for bacterial growth, MPs could affect the composition of the bacterial community in environmental media (Chi et al, 2021). Laboratory experiments show that the addition of microplastics with a higher affinity for DBP inhibited the degradation of DBP in sediments (Chi et al, 2021).…”

Perspectives on ecological risks of microplastics and phthalate acid esters in crop production systems

et al. 2021

Microplastics (MPs) and phthalate acid esters (PAEs) co-occur as emerging contaminants of global importance. Their abundance in soil is of increasing concern as plastic-intensive practices continue. Mulching with plastic films, inclusion in fertilizers, composts, sludge application, and wastewater irrigation are all major and common sources of MPs and PAEs in soil. Here, we review studies on the concentration and effects of MPs and PAEs in soil. While there is limited research on the interactions between MPs and PAEs in agroecosystems, there is evidence to suggest they could mutually affect soil ecology and plant growth. Therefore, we propose new research into 1) establishing an efficient, accurate, and simple method to quantify different types of microplastics in soils and plants; 2) exploring the behavior and understanding the mechanisms of co-transfer, transformation, and interactions with soil biota (especially in vegetable production systems); 3) assessing the risk and consequences of combined and discreet impacts of MPs and PAEs on plants and soil biota, and 4) preventing or reducing the transfer of MPs and PAEs into-and within-the food chain.

“…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.
