TL;DR: Investigation of the occurrence and distribution of sixteen antibiotics belonging to four groups in surface water, sediment and groundwater samples from the Wangyang River revealed that antibiotics were widely distributed in the studied area and the high intensity of aquaculture activities could contribute to the increasing levels of antibiotics.

TL;DR: The hydrophobic organic fractions and humic- and fulvic-like substances increased with time, whereas the HIM and the tyrosine-like materials decreased during the landfill process, rendering biological processing of leachates ineffective.

TL;DR: Municipal solid waste (MSW) compost contains a significant amount of humic substances, and mixed inoculation of MSW with complex microorganisms and lingo-cellulolytic during composting gave a greater degree of HA aromatization than inoculation with complexmicroorganisms or lingospecifics alone, indicating that inoculation in composting would improve the degree humification and maturation processes.

TL;DR: The sustainability of groundwater usage faces quality problem caused by anthropogenic activity as well as geogenic contamination, which is more significant in northern China due to extensive groundwater usage, arid climate and widespread Holocene strata.

TL;DR: Fluorescence excitation-emission matrix spectra coupled with parallel factor analysis and fluorescence regional integration analysis were utilized, and the projection pursuit cluster (PPC) model was applied to form a suitable index for overcoming the difficulties in multi-index evaluation.
