Abstract Plastic pollution is distributed across the globe, but compared with marine environments, there only rudimentary understanding of distribution and effects plastics in other ecosystems. Here, we review transport terrestrial, freshwater environments. We focus on hydrological catchments as well‐defined landscape units that provide an integrating scale at which plastic can be investigated managed. Diverse processes are responsible for observed ubiquity pollution, sources, fluxes sinks river poorly quantified. Early indications rivers hotspots supporting some highest recorded concentrations. River systems also likely pivotal conduits among floodplain, riparian, benthic transitional ecosystems they connect. Although ecological micro‐ nanoplastics might arise through a variety physical chemical mechanisms, consensus their nature, severity restricted. Furthermore, while individual‐level often graphically represented public media, knowledge extent impacts population, community ecosystem levels limited.

Over the last 60 years plastics production has increased manifold, owing to their inexpensive, multipurpose, durable and lightweight nature. These characteristics have raised demand for plastic materials that will continue grow over coming years. However, with production, comes material wastage creating a number of challenges, as well opportunities waste management industry. The present overview highlights pollution emphasising on various chemical substances (known "additives") contained in all products enhancing polymer properties prolonging life. Despite how useful these additives are functionality products, potential contaminate soil, air, water food is widely documented literature described herein. can potentially migrate undesirably lead human exposure via e.g. contact materials, such packaging.

Abstract Society has become increasingly reliant on plastics since commercial production began in about 1950. Their versatility, stability, light weight, and low costs have fueled global demand. Most are initially used discarded land. Nonetheless, the amount of microplastics some oceanic compartments is predicted to double by 2030. To solve this problem, we must understand plastic composition, physical forms, uses, transport, fragmentation into (and nanoplastics). Plastic debris/microplastics arise from land disposal, wastewater treatment, tire wear, paint failure, textile washing, at‐sea losses. Riverine atmospheric storm water, disasters facilitate releases. In surface waters plastics/microplastics weather, biofoul, aggregate, sink, ingested organisms redistributed currents. Ocean sediments likely ultimate destination. Plastics release additives, concentrate environmental contaminants, serve as substrates for biofilms, including exotic pathogenic species. Microplastic abundance increases fragment size decreases, does proportion capable ingesting them. Particles <20 μm may penetrate cell membranes, exacerbating risks. Exposure can compromise feeding, metabolic processes, reproduction, behavior. But more investigation required draw definitive conclusions. Human ingestion contaminated seafood water a concern. Microplastics indoors present yet uncharacterized risks, magnified time spend inside (>90%) polymeric products therein. Scientific challenges include improving microplastic sampling characterization approaches, understanding long‐term behavior, additive bioavailability, organismal ecosystem health Solutions globally based pollution prevention, developing degradable polymers reducing consumption/expanding reuse.

Abstract Microplastics are ubiquitous in estuarine, coastal, and deep sea sediments. The impacts of microplastics on sedimentary microbial ecosystems biogeochemical carbon nitrogen cycles, however, have not been well reported. To evaluate if influence the composition function communities, we conducted a microcosm experiment using salt marsh sediment amended with polyethylene (PE), polyvinyl chloride (PVC), polyurethane foam (PUF) or polylactic acid (PLA) microplastics. We report that presence alters community cycling processes. Compared to control sediments without microplastic, PUF- PLA-amended promote nitrification denitrification, while PVC amendment inhibits both These results indicate processes can be significantly affected by different microplastics, which may serve as organic substrates for communities. Considering this evidence increasing microplastic pollution, impact plastics global merits critical investigation.

Global plastics production has reached 380 million metric tons in 2015, with around 40% used for packaging. Plastic packaging is diverse and made of multiple polymers numerous additives, along other components, such as adhesives or coatings. Further, can contain residues from substances during manufacturing, solvents, non-intentionally added (NIAS), impurities, oligomers, degradation products. To characterize risks chemicals potentially released use, disposal, and/or recycling packaging, comprehensive information on all involved needed.
