Explore variations of DOM components in different landcover areas of riparian zone by EEM-PARAFAC and partial least squares structural equation model

Xiulei Zhang et al.

Summary: Dissolved organic matter (DOM) plays important roles in the distribution of contaminants and the carbon cycle in ecosystems. This study investigated the variation of DOM in different landcover areas of an urban river riparian zone using fluorescence excitation-emission matrix (EEM) spectroscopy and statistical analysis methods. The results showed that the composition and humification of soil DOM varied between different landcover types. Forest soils had higher humification than grassland and cropland soils. The dominant fractions of DOM were humic/fulvic-like in forests and tyrosine-like in grassland and cropland. The findings suggest that soil physiochemical properties and DOM sources influence the composition and humification of DOM in riparian areas.

Evaluating the Effects of Different Pretreatments on Anaerobic Digestion of Waste Activated Sludge Containing Polystyrene Microplastics

Yanjing Zeng et al.

Summary: This study investigated the effects of physical and chemical pretreatments on the anaerobic digestion of waste activated sludge containing polystyrene microplastics (PS-MPs). The results showed that thermal and chemical pretreatments significantly improved sludge disintegration and increased methane production. Chemical pretreatment had an impact on the leaching of microplastics, but did not affect the generation of reactive oxygen species. In terms of long-term effects, thermal pretreatment had the greatest influence on the proportion of methanogens. Considering the anaerobic digestion performance and the toxic alteration of microplastics, thermal pretreatment is recommended.
