“…The microplastic particles found in the present study were primarily blue fibers. A predominance of blue microplastic fibers in fish was also reported by Chota-Macuyama and Chong Mendoza (2020) for the Iquitos region, and Urbanski et al (2020) for the middle Tietê River basin, in southeastern Brazil. Fibers are considered among the most dangerous forms of microplastic due the ease with which they accumulate in the digestive tract, where they can cause more serious intestinal toxic effects than others forms of microplastic (Qiao et al 2019).…”

The contamination of aquatic environments by microplastic has become a major threat to biodiversity. The presence of microplastic is documented in the aquatic fauna of the oceans, but, in the Amazon basin, reports on microplastic occurrence are few. The present study surveyed microplastic occurrence in fishes in an area of the Peruvian Amazon. We sampled 61 specimens of 15 commercial species from local markets in the city of Iquitos, Loreto Department. We detected a total of 2337 microplastic particles, 1096 in the gills and 1241 in the internal organs (esophagus, stomach, intestine, liver, gonads, pancreas, swim bladder and heart). The prevalence of microplastic particles was 100% and the overall average abundance was of 38.3 particles per individual (17.9 particles per individual in gills and 20.3 particles per individual in internal organs). Most particles were found in carnivorous fish. There was no correlation of particle abundance with fish standard length and weight. These results provided evidence of the degree of microplastic contamination of the fish fauna in the region of Iquitos.

“…The continuous degradation of aquatic ecosystems is a growing concern (e.g., Pelicice et al 2017, Albert et al 2021. Pollution, in particular, has attracted mounting attention (e.g., Stelfox et al 2016, Azevedo-Santos et al 2019, Giarrizzo et al 2019, Urbanski et al 2020 because it has reached multiple aquatic environments and has caused substantial impacts on biodiversity. One important problem is the incorrect disposal or loss of fishing nets (Matsuoka et al 2005), which creates ghost nets that continuously entangle aquatic animals in the environment (Smolowitz 1978, Iriarte & Marmontel 2013.…”

“…Detrimental effects can occur through ingestion, animal entanglement, and accumulation and leakage of toxic compounds (van Emmerik and Schwarz, 2020). In freshwater systems, there is evidence that plastic is ingested by macroinvertebrates (Hurley et al, 2017;Windsor et al, 2019), fish (Horton et al, 2018;Urbanski et al, 2020), and birds (Holland et al, 2016). Furthermore, a recent study states that plastics are transferred throughout the food web (D'Souza et al, 2020), which could lead to bioaccumulation.…”

Inland Navigation Contributes to the Remobilization of Land-Based Plastics Into Riverine Systems

et al. 2022

Riverine systems are directly affected by plastic pollution and function as pathways for plastic transport to the sea. Plastic litter can enter the water by remobilization from the bed or from the riverbank, after which it can be transported with the flow. The process of remobilization is still poorly understood. To get a detailed understanding of the role rivers play in plastic transport and hence develop management measures to prevent or mitigate plastic transport it is vital to get a fundamental understanding of the factors contributing to remobilization of plastic on the riverbank. Therefore, we investigated how the wave action of inland navigation, one of the dominant actors in anthropogenic rivers, affects the remobilization of land-based plastics. Quantification of remobilization was performed along the riverbank of an intensely navigated river in the Netherlands (the river Waal) allowing for a real-world assessment of remobilization. Plastic pieces were placed at standardized distances from the average waterline to determine the plastic remobilization along the riverbank at different locations. Subsequently, wave actions of passing inland navigation was used to assess plastic remobilization. Inland navigation induced wave action was found to significantly cause remobilization of plastics present on the riverbank. The distance of the plastic object to the waterline combined with the wave height, riverbank slope and plastic size significantly affected remobilization probability. Overall, the remobilization effect was strongest on plastics present within ≤ 1.0 m from the waterline. With a wave height ≥ 0.5 m all plastics present up to 3.0 m from the waterline were remobilized and thereby potentially transported downstream through the river.
