New insights into the vertical distribution and microbial degradation of microplastics in urban river sediments.

TL;DR: Wang et al. as mentioned in this paper summarized different laboratory technologies including light irradiation, chemical oxidation, heat treatment and γ-ray irradiation to simulate and accelerate the aging of microplastics, and evaluated the feasibility by comparison with natural processes.

TL;DR: Wang et al. as mentioned in this paper investigated microplastics in the whole Yangtze River Basin of China by sampling the water, sediment, and soil, with an average abundance of 1.27 items/L, 286.20 items/ kg, and 338.09 items/kg for water, sediments, and soils, respectively, with polypropylene and polyethylene being the most abundant polymers.

TL;DR: In this paper, a three dimensional hydrodynamic and particle transport modelling framework was created to investigate the dispersal and transport processes of microplastic particles commonly present in the environment, namely, polyethylene (PE), polypropylene (PP), polyamide (PA), and polyethylenes terephthalate (PET) in river sediments.

TL;DR: In this article , the contamination and potential risks of antibiotics and microplastics in the groundwater of a drinking-water source area and found a correlation between them, indicating that risk management of antibiotics in groundwater should be highly concerned.

TL;DR: In this study, experiments were performed using network analysis to investigate the effects of different carbon sources, including blank, citrate, glucose and lactate, on indigenous bacterial communities and on the pentachlorophenol (PCP) dechlorination in two soils to provide insight into the biological mechanism of the impact of exogenous carbon sources on PCP de chlorination pathways by modifying soil bacterial networks.

TL;DR: In this paper, the authors investigated wind-driven nearshore sediment resuspension in Lake Tahoe, California-Nevada (USA) and found that wind-waves were the dominant mechanism resulting in sediment resumption as corroborated by simultaneous increases in shear stress and total measured sediment concentration.

TL;DR: This study provides important insights as the first to analyse microplastic-paint biofilm communities and paves the way for future research.

TL;DR: Two strains of gram-negative bacteria isolated because of their abilities to decompose xenobiotic compounds were subjected to a polyphasic taxonomic study and two novel species, Pseudomonas benzenivorans sp.
