Summary: Enhanced treatment of incineration bottom ashes (IBA) from municipal solid waste incineration can contribute to a circular economy by recovering metals and glass for recycling. The study evaluated the effects of an enhanced treatment on different types of IBAs and found general differences between fluidized bed combustion (FB-IBA) and grate incineration bottom ashes (G-IBA).

Summary: This study assessed the levels of PCDD/Fs and DL-PCBs in sea turtles from the Tyrrhenian Sea, finding that DL-PCBs levels were higher in Caretta caretta than in Chelonia mydas, possibly due to different eating habits. Positive correlations were found between PCB-81 and body size parameters, indicating that contaminant burden is related to body size. Risk assessment measured in TEQ values showed higher levels of PCDD/Fs and DL-PCBs in Caretta caretta compared to Chelonia mydas.

Summary: The research results show that significantly higher SO2 capture efficiency can be achieved in oxyfuel conditions compared to air conditions. There are fundamental differences in SO2 capture between air and oxyfuel conditions in real combustion environments. The performance of the sorbent is important mainly at lower Ca/S molar ratios, and the difference in SO2 capture between sorbents decreases with increasing Ca/S ratio.

Summary: Field studies were conducted to investigate the emission and distribution characteristics of dioxins in a circular fluidized bed boiler by increasing the chlorine concentration in the feedstock. The results showed that the addition of chlorine increased the concentration of PCDD/Fs in all gaseous and ash samples, with the largest increment observed in electrostatic ash and flue gas. PCDDs were the dominant congeners in the flue gas, while the distribution of PCDD/F changed from PCDD-predominant to PCDF-predominant as the chlorine content in the feedstock increased. Highly chlorinated PCDD/F congeners were the primary contributors to dioxin concentration in flue gas and bottom ash samples, while low-chlorinated congeners became critically dominating in electrostatic and bag filter ash.

Summary: Differences in PCDD/F formation between hazardous waste incinerators (HWIs) and municipal solid waste incinerators (MSWIs) were identified. Distillation residue showed the highest PCDD/F concentrations, and aromatic rings and C-O bond organics were highly correlated with PCDD/F concentrations. PCDD/Fs were formed through chlorination and structure formation processes. These findings enhance understanding of PCDD/F formation during HW incineration, facilitate optimization of HWI operation conditions, and reduce future PCDD/F emissions.

Summary: The aim of this study was to assess the human health risk associated with the presence of persistent organic pollutants (POPs) in the livers of terrestrial animals. The liver samples from sheep and pigs in Poland were found to exceed the maximum concentration limits for certain POPs. According to the results, chicken liver consumption poses the lowest risk, while pork and beef livers should be consumed in limited amounts for risk avoidance, and mutton liver should not be consumed at all.

Summary: This study was conducted to evaluate the formation, emission, and flux of polychlorinated dibenzo-p-dioxins and dibenzofurans (PCDD/Fs) from industrial-organic-solid-waste incineration in a fluidized-bed plant. The results showed that the concentrations of toxic and total PCDD/Fs in flue gas, fly ash, and bottom ash were higher compared to municipal-solid-waste incineration, possibly due to the higher chlorine content in industrial waste. However, the emitted PCDD/Fs still met the criteria. De novo synthesis was found to be the dominant formation pathway, while high-temperature and precursor syntheses were excluded. Chlorination of DD/DF contributed to the formation of PCDD/Fs to some extent. The purification process reduced 99.6% of PCDD/Fs in the flue gas, resulting in a discharge rate of 7.25 μg I-TEQ/h of PCDD/Fs in the gas phase, while most of the PCDD/Fs (over 99%) were accumulated in the fly ash, with a discharge rate of 3.56 mg I-TEQ/h into the environment.

Summary: High-intensity ball milling was used to modify model fly ash samples, affecting their characteristics and reactivity in generating PCDD/F. The choice of stainless steel or zirconia as ball mill materials had varying influences on the fly ash samples, with more pronounced changes observed in those milled with stainless steel. However, the reactivity of all fly ash samples, particularly the Cu-doped ones, was significantly reduced after prolonged milling and could be safely disposed of in landfills.

Summary: The study found that multi-walled carbon nanotubes (MWCNTs) have higher adsorption capacity to adsorb 1,2,4-TrCIBz compared to Tenax TA, and can desorb at a lower temperature. MWCNTs showed good stability for concentration and temperature of 1,2,4-TrCIBz, but regeneration was not possible at 100 ppbv.

Summary: The present study investigates the fluidization, combustion performance, and collected fly ash analysis of coniferous forest residue, such as pine needles. The experimental results show that pine needles with a 2% concentration mix well with silica sand at a fluidization number of 4. Combustion studies indicate that pine needles can be easily combusted inside the combustor. SEM/EDS analysis reveals the morphology and compositions of ash and sand.

Summary: Online monitoring and feedback control of PCDD/F emissions in municipal solid waste incineration can help ensure compliance with national standards. Key operating parameters include maintaining furnace outlet temperature above 800 degrees C, bed pressure above 13 kPa, or stable oxygen content above 10% to effectively reduce PCDD/F emissions.

Summary: The use of the 3T method in combustion can lead to elevated operating temperature in baghouse filters for MSWI systems, which is potentially detrimental to the emission control of PCDD/Fs. This study conducted a field study and laboratory investigation to analyze the distribution, variation, and memory effect of PCDD/Fs at high operating temperatures. The key factor inducing the memory effect was identified as temperature, which facilitated the formation and desorption of PCDD/Fs.

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. Targeting metabolic and epigenetic reprogramming in macrophages induced by PM is a promising strategy for COPD treatment.

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.

Deterministic processes dominate the assembly of mesopelagic plastisphere microbial communities, while stochastic processes shape the assembly of bathypelagic microbial communities. The relationships between microorganisms in the mesopelagic layer are more complex and stable, with Proteobacteria and Actinobacteriota playing important roles.
