Summary: In this study, yellow perch captured at four sites in the Lake St. Clair-Detroit River system were used to assess the sublethal effects of industrial pollution. The results indicated that higher sediment levels of industrial contaminants at the most downstream Detroit River site were associated with liver detoxification activity, reduced brain size, and disrupted food web in perch. Somatic growth and relative gut size were also affected by industrial pollution. Therefore, bioindicators of fish trophic ecology can be useful in assessing aquatic ecosystem health.

Summary: This study estimates the contributions of dry and wet deposition of total phosphorus (TP) to the Great Lakes region, using historical datasets and observing seasonal and geographic variations. The results indicate that wet deposition dominates over dry deposition in all lakes, except for Lake Huron. However, considering dry deposition of different particle sizes is necessary to accurately estimate the atmospheric deposition of TP over the Great Lakes.

Summary: This study quantified the contributions of moisture source regions to precipitation in the Great Lakes Region (GLR) and identified the primary sources of moisture as the Great Plains (GPs) and the GLR itself. The findings showed a shift in the peak timing of moisture contribution from the GLR and GPs, explaining the double peaks in GLR precipitation in June and September. Furthermore, it was observed that moisture from the GPs contributed more to heavy precipitation, while moisture from the GLR contributed more to light precipitation. Additionally, there was a statistically significant increasing trend in moisture contribution from the mid-Pacific, attributed to changes in atmospheric circulation.

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.
