“…2018; Fahrenfeld et al . 2019). Besides, the wear and tear of the tires during the driving of the car, plastic dust generated by abrasion of shoe soles, road marking materials, marine coatings are also huge sources of MPs, and according to the statistics, approximately 13 000 tonnes of MPs are released from all the tires every year (James 1983; Lassen et al .…”

According to the statistics, 8.3 billion metric tonnes of plastics have been produced since 1950s, which is far more than other synthetic materials and the annual production which are about 500 million tonnes per year at present. The production of plastics makes microplastics pollution extremely widespread distribution, which will have a lasting impact on the global environment, especially on the aquaculture systems. And the distribution of the microplastics is extremely imbalanced around the global waters. In the present review, we have summarized the development of aquaculture in the World and China based on the existing data sources. And the total aquaculture production of the World will over 90 million tonnes, which will exceed the capture production in 2020. Aquaculture products will become one of the most important sources of high-quality protein. However, we found that many kinds of microplastics are detected and enriched in both farmed and captured species. Both endogenous and exogenous factors like the use of fishing plastic products, factory farming facility and equipment, natural and synthetic feed, animal health products, aquaculture fortifier and aquatic food additives make accumulation of microplastics easier. In addition, the safety of aquaculture products is closely related to human health because the residues of microplastics in fish leading to various potential hazards. In summary, this paper reviewed the relationship between microplastics and aquaculture, aimed at calling for the rational and restricted use of plastic products in the aquaculture ecosystems.

“…There is also a less well-understood contribution from atmospheric deposition, documented by findings of MPs in outdoor air [3]. However, the relative contribution of the various land-based MPs sources and their pathways to the environment are not well understood, leaving numerous uncertainties regarding which sources are dominant [4]. MPs are present in lakes and rivers, showing that freshwaters receive MPs from land-based sources and also transport MPs to the oceans [5,6].…”

Large amounts of microplastics (MPs) enter our environment through runoff from urban areas. This study presents results for MPs in stormwater from a wet retention pond in terms of its water, sediments, and vertebrate fauna. The analysis was done for the size range 10–500 μm, applying a focal-plane array-based µFourier transform infrared (FPA-µFTIR) imaging technique with automated data analysis. Sample preparation protocols were optimized towards this analytical method. The study revealed 270 item L−1 in the pond water, corresponding to 4.2 µg L−1. The MPs in the pond were highly concentrated in its sediments, reaching 0.4 g kg−1, corresponding to nearly 106 item kg−1. MPs also accumulated in vertebrates from the pond—three-spined sticklebacks and young newts. In terms of particle numbers, this accumulation reached levels nearly as high as in the sediments. The size of the MPs in the pond water and its fauna was quite similar and significantly smaller than the MPs in the sediments. A rough estimate on MPs retention in the pond indicated that MPs were retained at efficiencies similar to that of other particulate materials occurring in the stormwater runoff.

“…Furthermore, standardizing measurements across samples to allow for comparison among studies, sources and environment is important (Filella, ), with the diversity of current measurements limiting an understanding of the relative concentrations of plastic pollution across the environment. Through investigating the characteristics and concentration of plastics released from each potential source, a mixing‐model type assessment can be used to understand the entrance and flux of plastics within catchments (Fahrenfeld, Arbuckle‐Keil, Naderi Beni, & Bartelt‐Hunt, ). Further to this, determining the specific contributions from sources will enable targeted mitigation, ultimately aimed at preventing the entrance of plastics into the natural environment.…”

Plastic pollution is distributed across the globe, but compared with marine environments, there is only rudimentary understanding of the distribution and effects of plastics in other ecosystems. Here, we review the transport and effects of plastics across terrestrial, freshwater and marine environments. We focus on hydrological catchments as well‐defined landscape units that provide an integrating scale at which plastic pollution can be investigated and managed. Diverse processes are responsible for the observed ubiquity of plastic pollution, but sources, fluxes and sinks in river catchments are poorly quantified. Early indications are that rivers are hotspots of plastic pollution, supporting some of the highest recorded concentrations. River systems are also likely pivotal conduits for plastic transport among the terrestrial, floodplain, riparian, benthic and transitional ecosystems with which they connect. Although ecological effects of micro‐ and nanoplastics might arise through a variety of physical and chemical mechanisms, consensus and understanding of their nature, severity and scale are restricted. Furthermore, while individual‐level effects are often graphically represented in public media, knowledge of the extent and severity of the impacts of plastic at population, community and ecosystem levels is limited. Given the potential social, ecological and economic consequences, we call for more comprehensive investigations of plastic pollution in ecosystems to guide effective management action and risk assessment. This is reliant on (a) expanding research to quantify sources, sinks, fluxes and fates of plastics in catchments and transitional waters both independently as a major transport routes to marine ecosystems, (b) improving environmentally relevant dose–response relationships for different organisms and effect pathways, (c) scaling up from studies on individual organisms to populations and ecosystems, where individual effects are shown to cause harm and; (d) improving biomonitoring through developing ecologically relevant metrics based on contemporary plastic research.
