Quantification and characterization of macro- and mesoplastic items in the water column of the river Waal [PDF]
Science of the Total Environment, 2023 Although studies on plastic concentrations mainly focus on the marine environment, recently, an increasing number of studies point out environmental consequences in freshwater environments around the world. However, there still is a paucity of field data on the abundance of riverine plastic items, in particular in the water column.

Characterization of microplastic and mesoplastic debris in sediments from Kamilo Beach and Kahuku Beach, Hawai'i [PDF]
Marine Pollution Bulletin, 2016 Sediment samples were collected from two Hawai'ian beaches, Kahuku Beach on O'ahu and Kamilo Beach on the Big Island of Hawai'i. A total of 48,988 large microplastic and small mesoplastic (0.5–8 mm) particles were handpicked from the samples and sorted ...

Mesoplastic contamination in the Deli River Medan: A Pre-Assessment
IOP Conference Series: Earth and Environmental Science, 2023 Abstract Mesoplastics are plastics with a diameter between 0.5 and 2.5 cm. The purpose of this study was to characterize the properties and quantity of floating mesoplastics in the water column and at the surface. Sampling was conducted using a net with a 0.5 cm square mesh dimension at five separate places selected based on the ...

Microplastic and mesoplastic contamination in canned sardines and sprats
Science of the Total Environment, 2018No report was found on the occurrence of microplastics in processed seafood products that are manufactured for direct human consumption. This study investigates the potential presence of micro- and mesoplastics in 20 brands of canned sardines and sprats originating from 13 countries over 4 continents followed by their chemical composition determination

Micro- and mesoplastic pollution along the coast of Peru
Environmental Science and Pollution Research, 2023Peru suffers from poor solid waste and coastal management, as well as evidenced plastic pollution in various forms. However, studies in Peru focusing on small plastic debris (i.e., meso- and microplastics) are still limited and inconclusive. Thus, the present study investigated the abundance, characteristics, seasonality, and distribution of small ...

Mesoplastic (MaP) and macroplastic (MeP) coming from plastic mulching tend to cause negative effects on biota in ecosystems. However, it is still not clear how field management influences the distribution of MeP/MaP in soils. In this study, MeP/MaP was investigated in 0-20 and 20-30 cm soil layers of three vegetable fields (3.4-6.5 ha) after 13 years ...

Characteristics of meso-sized plastic marine debris on 20 beaches in Korea
Marine Pollution Bulletin, 2017 We surveyed the abundance and accumulation patterns of mesoplastic marine debris (5-25 mm) on 20 beaches in Korea. The mean abundance of it was 13.2 items/m(2), and the mean weight was 1.5 g/m(2). Hard plastic and Styrofoam were the dominant types.

Microplastic and mesoplastic pollution in farmland soils in suburbs of Shanghai, China
Environmental Pollution, 2018Microplastics are emerging pollutants which have been extensively detected in water environments. However, little is known about microplastic pollution in soil environments. In this study, we investigated microplastics and mesoplastics in farmland soils from twenty vegetable fields around the suburbs of Shanghai.

Methodology and applications of mesoplasticity in manufacturing sciences
International Journal of Mechanical Sciences, 1993Abstract The studies on plasticity have been conventionally divided into two categories, namely macroplasticity and microplasticity. Mesoplasticity emerges as a link between these two schools which introduces the essential microplasticity concepts to various intermediate (or meso-) scales, and represents the connection between the continuum-based ...

Selective transport of microplastics and mesoplastics by drifting in coastal waters
Marine Pollution Bulletin, 2014The quantity and size distributions of small plastic fragments in the Seto Inland Sea, Japan were investigated using field surveys and a numerical particle-tracking model. The model was used to interpret the distributions of small plastic fragments and the possible transport processes in coastal waters.
