“…While most plastic and MP studies focused on the various compartments of the marine environment, investigations carried out in freshwater bodies have expanded significantly in recent years ( Talbot and Chang, 2022 ). Freshwater bodies, such as rivers, lakes, and lagoons, display different types of hydrodynamics compared to the marine environment and may act as transport pathways for litter to reach the oceans ( Cai et al, 2021 ). For this reason, freshwater bodies play an important role in the litter dynamics across aquatic systems.…”

Personal protective equipment (PPE) pollution has become one of the most pending environmental challenges resulting from the pandemic. While various studies investigated PPE pollution in the marine environment, freshwater bodies have been largely overlooked. In the present study, PPE monitoring was carried out in the vicinity of Lake Tana, the largest lake in Ethiopia. PPE density, types, and chemical composition (FTIR spectroscopy) were reported. A total of 221 PPEs were identified with a density ranging from 1.22 × 10 −5 PPE m −2 (control site S1) to 2.88× 10 −4 PPE m −2 with a mean density of 1.54 × 10 −4 ± 2.58 × 10 −5 PPE m −2 . Mismanaged PPE waste was found in all the sampling sites, mostly consisting of surgical face masks (93.7%). Statistical analyzes revealed significantly higher PPE densities in sites where several recreational, touristic, and commercial activities take place, thus, revealing the main sources of PPE pollution. Furthermore, polypropylene and polyester fabrics were identified as the main components of surgical and reusable cloth masks, respectively. Given the hazard that PPEs represent to aquatic biota (e.g., entanglement, ingestion) and their ability to release microplastics (MPs), it is necessary to implement sufficient solid waste management plans and infrastructure where lake activities take place. Additionally, local authorities must promote and ensure sustainable tourism in order to maintain the ecosystems in Lake Tana. Prospective research priorities regarding the colonization and degradation of PPE, as well as the release of toxic chemicals, were identified and discussed.

“…It was because zone 2 was actually closed surface water, which was not directly connected to other rivers around the catchment area, that this zone noted the lower AMWI values in the pre-MCO period. Cai et al ( 2021 ) found that closed surface water systems, such as rivers from the Tibet Plateau and Indian Rivers, tended to accumulate fewer pollutants than open water systems. The in situ measurement of Fe concentration in zone 2 was averaged at 685 g/l.…”

Mining activities in the Chini Lake catchment area have been extensive for several years, contributing to acid mine drainage (AMD) events with high concentrations of iron (Fe) and other heavy metals impacting the surface water. However, during the restriction period due to the COVID-19 outbreak, anthropogenic activities have been suspended, which clearly shows a good opportunity for a better environment. Therefore, we aimed to analyze the variation of AMD-associated water pollution in three main zones of the Chini Lake catchment area using Sentinel-2 data for the periods pre-movement control order (MCO), during MCO, and post-MCO from 2019 to 2021. These three zones were chosen due to their proximity to mining areas: zone 1 in the northeastern part, zone 2 in the southeastern part, and zone 3 in the southern part of the Chini Lake area. The acid mine water index (AMWI) was a specific index used to estimate acid mine water. The AMWI values from Sentinel-2 images exhibited that the mean AMWI values in all zones during the MCO period decreased by 14% compared with the pre-MCO period. The spatiotemporal analysis found that the highest polluted zones were recorded in zone 1, followed by zone 3 and zone 2. As compared with during the MCO period, the maximum percentage of increment during post-MCO in all zones was up to 25%. The loosened restriction policy has resulted in more AMD flowing into surface water and increased pollution in Chini Lake. As a whole, our outputs revealed that Sentinel-2 data had a major potential for assessing the AMD-associated pollution of water.

“…Additionally, they examined the migration routes and transportation processes employed by microplastic from landfills to nearby water bodies and subterranean or freshwater. The main land-toocean routes for the transportation of microplastics are streams (Cai et al (2021). The connection of waterways was altered by profitable dam building, which decreased the flow of microplastics into the ocean.…”

Materials called microplastics (MiPs) exist for a very long time in nature without decomposing. As a result, they are crucial to environmental degradation. Since MiPs may break down into little particles because of the oxidation and degradation of the polymer structures while exposed to UV rays like sunshine, they could be carried over long ranges by rain and winds. Furthermore, MiPs negatively impact human health through the food chain. The investigation was conducted in Dianchilake in Yunnan, China. Raman-Microscope and scanning electron microscope (SEM) instruments were used to examine lake data. MiP elements that are substantially smaller than those that have previously been reported were found in a large number of samples that were evaluated with a Raman-Microscope. Also, the Analysis of variance (ANOVA) model is used in this research for statistical analysis. We must reduce the number of microplastics in lakes and rivers, particularly in drinking water, by researching the optimal transport routes of these tiny pieces of plastic. This research will serve as a valuable foundation for future studies on the pathways of microplastic migration in other lakes and rivers.
