Summary: Characterization of biochar-derived dissolved organic matter (DOM) from six macroalgae was conducted to explore its potential applications. Pyrolysis temperature and extraction solution pH significantly influenced the DOM characteristics. Fluorescence excitation-emission matrix spectroscopy with PARAFAC analysis identified five humic-like substances and one protein-like substance. The proportion of protein-like substance was lower than that of humic-like substances in MBDOM, regardless of extraction solution pH. The study revealed that DOM from macroalgal biochar is more autochthonous and humified compared to the corresponding biomass.

Summary: With the increasing amount of wastewater discharges, the influence of treated effluent on the photochemistry of natural receiving waters has become more significant. The effect of treatment operations on the photo-reactivity of dissolved organic matter (DOM) has gained attention, as well-established correlations between spectroscopic measurements and photochemical behaviors become unreliable in treated DOM. This research investigates the variations of optical and photochemical properties of DOM after ozonation and explores the correlations between fluorescence and reactive species photo-production through parallel factor analysis (PARAFAC).

Summary: This study investigated the interaction among dissolved organic matter (DOM) components, environmental factors, and oxytetracycline (OTC) tolerant bacteria during chicken manure composting. The results showed that OTC residues in chicken manure can affect the transformation of DOM components during composting. This transformation is indirectly influenced by the OTC stress on the microbial community activity. The presence of OTC tolerant bacteria after the high temperature period of composting is positively correlated with the humification process.

Summary: This study analyzed the fluorescence characteristics of neutral dissolved organic matter (DOM) in the central Huaihe River and its tributaries using three-dimensional fluorescence spectroscopy. The sources of the DOM were identified under complex pollution conditions using parallel factor analysis (EEM-PARAFAC). The main components of the DOM in the central Huaihe River were terrestrial ultraviolet A humus, terrestrial humic-like substances, and tryptophan-like substances. EEM-PARAFAC accurately analyzed the composition and concentrations of the DOM and identified the sources of pollutants, providing a theoretical basis for water quality control in the Huaihe River basin.

Summary: As the consumption of Chinese medicine resources increases, the waste of traditional Chinese medicine extraction cannot be disposed of reasonably, which has a serious impact on the environment. Dissolved organic matter (DOM) in herbal extraction residue can bind to heavy metals (HMs), creating potential environmental risks. This study found that protein-like substances are dominant in the residual DOM of Chinese medicine extracts, becoming the main factor of water quality deterioration. The N-H groups in the protein-like materials prioritize binding with Cu(II). The study emphasizes the importance of continuous attention to the impact of herbal extraction residue on the geochemical behavior of HMs.

Summary: In this study, the effects of attapulgite on biogas production during anaerobic co-digestion of rice straw and cattle dung were explored. Spectroscopic techniques were used to investigate the characteristics, components, and evolution of dissolved organic matter (DOM). The results showed that the addition of attapulgite increased the biogas yield, with higher yields observed for substrates with attapulgite compared to those without attapulgite. PARAFAC analysis identified six components of DOM, including protein-like, fulvic-like, and humic-like substances. The presence of attapulgite promoted the growth of methanogenic bacteria, accelerated methane generation, and increased biogas production by facilitating the conversion of DOM.

Summary: In this study, a human physiologically based pharmacokinetic (PBPK) model of diethyl phthalate (DEP) was developed to assess its toxicity. The model considers the distribution and metabolism of DEP and its active metabolite monoethyl phthalate (MEP) in different tissue compartments. Sensitivity analysis and Bayesian Markov chain Monte Carlo (MCMC) simulations were performed to evaluate the uncertainty and variability of the model parameters. The results suggest that dermal absorption is an important route of exposure to DEP in the environment.

Summary: This study investigates the feasibility and mechanisms of a chemical-free nanobubble-based AOP for treating organic micropollutants in water. The results show that the oxygen nanobubble AOP has a significantly higher removal efficiency compared to air and nitrogen nanobubbles. The treatment performance is not affected by pH and the presence of ions. Higher initial concentrations of the micropollutant lead to slower treatment processes, but similar removal performance is achieved in the end. The presence of organic matter reduces the removal rate of the micropollutant. The results have practical feasibility for water and wastewater treatment.
