Summary: This article presents the current knowledge on Canadian PAC emission sources, with forest fires dominating the emissions nationally. Non-industrial sources are estimated to be the second largest contributor, showing moderate decreases in recent decades. Industrial point sources have seen considerable reductions, while fugitive emissions from other industrial sources remain a gap in our understanding. Overall, there is uncertainty in emissions data and regional/local scale examination is needed to determine the sources contributing most to human and ecosystem exposure.

Summary: In this study, the removal efficiency of antimony (Sb) and naphthalene (Nap) from contaminated soil was investigated using carboxymethyl-beta-cyclodextrin (CMCD) leaching. The results showed that CMCD had a high removal efficiency for Sb and Nap, and the mechanisms of remediation involved complexation and inclusion reactions. FTIR analysis indicated the complexation of Sb with the carboxyl and hydroxyl groups on CMCD, while NMR analysis suggested the inclusion of Nap. These findings suggest that CMCD is an effective solvent for remediating soil contaminated with heavy metals and PAHs.

Summary: In recent years, there has been significant progress in the study of thermal transformation of waste into valuable materials such as biochar. High-temperature processes can lead to the formation of toxic polycyclic aromatic hydrocarbons (PAHs). However, the pyrolysis process can also result in the formation of derivatives containing oxygen, nitrogen, or sulfur, which may have higher toxicity than parent PAHs. The bioavailability of PAHs is an important parameter in the agricultural application of carbonaceous materials.

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.

Summary: This study aims to explore the effects of thiencarbazone-methyl center dot isoxaflutole on soil microflora and the potential mitigation mechanisms to bacterial communities. It was found that increasing the application of thiencarbazone-methyl center dot isoxaflutole resulted in increased stress on soil bacterial community structure and diversity. Increasing soil pH was recognized as a key factor in improving the diversity and structure of soil microflora. Supplemental use of nitrapyrin or modified attapulgite can increase soil pH and improve bacterial diversity.
