Summary: Section 405(d) of the Clean Water Act mandates the US Environmental Protection Agency to review sewage sludge regulations and identify pollutants in biosolids that may pose risks to human health or the environment. Through biennial reviews and national surveys, the EPA has compiled a list of 726 chemicals found in biosolids and reported concentration data for 484 chemicals. This Biosolids List aids the EPA in assessing the potential risk of chemical pollutants in biosolids.

Summary: Poly- and perfluoroalkyl substances (PFASs) are synthetic chemicals introduced to the environment through anthropogenic activities, with major sources being firefighting foam, wastewater effluent, landfill leachate, and biosolids. Remediation of PFAS contaminated soils is challenging due to their stability and mixture complexity. Mobilizing amendments increase PFAS mobility and bioavailability, while immobilizing amendments decrease transfer to food chain and leaching to water sources. Future research should focus on quantifying potential leaching of mobilized PFAS and monitoring long-term stability of immobilized PFAS.

Summary: This study developed a closed-loop hydrometallurgical treatment process for the removal and recovery of heavy metals (HMs) from biosolids. Mild acid treatment using 3% v/v H2SO4 successfully extracted common HMs from biosolids into the aqueous phase. The dissolved metals were then recovered through staged NaOH precipitation and adsorption.

Summary: Lipase-producing Pseudomonas strain was screened and optimized for enhanced production of lipase. The lipase from Pseudomonas plecoglossicida S7 showed high activity and stability over a wide range of temperature and pH. The enzyme also exhibited tolerance to various solvents and retained activity in the presence of sodium dodecyl sulfate. Immobilization of the enzyme further improved its thermal and pH stability. The lipase had potential applications in detergent formulation, wastewater treatment, and biodegradation of oil.

Summary: Current evidence supports there are probably no clinically important differences in outcomes between ISBCS and DSBCS, but with lower costs for ISBCS. However, the amount of evidence is limited, and the certainty of the evidence was graded moderate to very low. In addition, there is a need for well-designed cost-effectiveness studies.

Summary: Per and polyfluoroakyl substances (PFAS) are a type of emerging contaminants commonly found in the bloodstream of most humans in the U.S. These substances are present in both Class A and B municipal biosolids. The potential contamination of groundwater caused by PFAS leaching through soil after land application of biosolids has generated discussions about possible bans. This commentary discusses various factors that need to be considered to determine if PFAS from land applied biosolids is a significant source of human exposure via groundwater, including the occurrence of PFAS in biosolids and biosolids-amended soils and other critical factors.

Summary: The study focused on the development of PHAMs for immobilizing lipase to reduce the acid value of RBO. The PHAMs effectively enhanced the catalytic activity of lipase and provided a micro-water environment to prevent hydrolysis of lipid products. The L-PHAMs demonstrated a high immobilization capacity, enhanced activity, and excellent reusability, making them a promising method for deacidification of high-acid rice bran oil.

Summary: This paper introduces a novel dielectric spectroscopic technique for investigating the freshness and adulterated agents in milk. The study reveals an inverse relationship between temperature and shelf-life, as well as the real part of the complex permittivity (epsilon') of the samples at frequencies ranging from 0.1 to 3 GHz. A linear relationship is also observed between epsilon' and epsilon, storage time, and water content at 2 GHz. Furthermore, a linear relationship is found between the concentrations of five adulterants' agents and both epsilon' and epsilon parts. This technique has the potential to be used for rapid online monitoring of milk quality in milk production facilities.

Summary: The development of alternate sources for natural pigments is important to overcome the use of artificial coloring and to benefit the food industry. This study investigated the effects of different light sources and temperatures on the pigment yield, lovastatin production, and biomass of Monascus ruber. The results showed that optimal temperature and exposure to certain light conditions enhance pigment and lovastatin production. However, exposure to other color lights significantly reduces fungus growth and pigment yield. Darkness also influences pigment production and biomass yield. The findings provide valuable knowledge for the production of functional foods and industrial applications.

Summary: Treating sulfate-rich wastewater with high methane recovery is challenging due to sulfide inhibition. In this study, an electrical voltage (EV) was applied to enhance methanogenesis and sulfidogenesis. The EV-applied reactor demonstrated significantly increased methane production and sulfate removal compared to the control reactor. The microbial community analysis revealed higher abundance of sulfate-reducing bacteria and genes related to resistance against H2S toxicity in the EV-applied reactor.

Summary: Phytoremediation of metals from water and nutrient media exposed to waste metal cutting fluid was tested using Azolla imbricata. Results showed that biomass was higher in nutrient media than in water media without waste metal cutting fluid. However, growth failed when exposed to high concentrations of waste metal cutting fluid. Correlation analysis revealed that biomass was positively affected by temperature and negatively affected by humidity and metal accumulation. The average accumulations of Al, Cd, Cr, Fe, Pb, and Zn were observed and the bioconcentration factor indicated Azolla imbricata acts as a hyperaccumulator of Zn and as an accumulator or excluder of other metals. Overall, the phytoremediation performance of Azolla imbricata in multi-metal-contaminated waste metal cutting fluid was high in water media under all environmental conditions. The use of water media was determined to be an economically feasible approach for the removal of metals from waste metal cutting fluid.

Summary: This study investigated the potential of restoration (RP) and deterioration (DP) as indicators for assessing the stability of anaerobic digestion. RP and DP are calculated based on the balance between different reaction rates, while the instability index (ISI) is the ratio of DP to RP. The study found that an ISI standard deviation above 0.2 indicates instability in the biochemical reactions, while an average ISI below 0.05 indicates a stable digestion process.

Summary: This study reveals that chronic exposure to PM induces chronic inflammation and development of COPD by dysregulating NAD+ metabolism and subsequent SIRT1 deficiency in pulmonary macrophages. Activation of SIRT1 by resveratrol effectively mitigates PM-induced inflammation and COPD development.

Summary: Microplastic contamination in marine ecosystems poses a growing concern due to its trophic transfer and negative effects on marine organisms. This study investigates the transfer and impacts of polystyrene microplastics in an estuarine food chain. The results show that microplastics can be transferred through the food chain, although the transfer rates are low. The exposed organisms exhibit stress responses, suggesting the potential risk of microplastics reaching humans through the food chain.

Summary: This study measured the levels of phthalate metabolites in breast milk collected from mothers in southern China. The results showed that phthalates are still prevalent in the region, and breastfeeding contributes to phthalate intake in infants. However, the levels detected do not pose significant health risks to infants based on dietary exposure. The increasing exposure to certain phthalates calls for further research into their sources and potential risks.
