Summary: The coal-to-gas process produces carbon dioxide, leading to global warming, and its wastewater treatment results in highly organically toxic sludge. Scenedesmus obliquus is a promising solution to these environmental issues, with a focus on its photosynthetic pigments. The optimal CO2 concentration for the growth of Scenedesmus obliquus was found to be 30% after increasing the CO2 concentration from 0.05% to 100%. The cultivation of Scenedesmus obliquus resulted in the accumulation of photosynthetic pigments and a significant reduction in the organic toxicity of the sludge extract.

Summary: This study compares the toxicity and biodegradation of rac-glufosinate-ammonium and L-glufosinate-ammonium in the aquatic organism Scenedesmus obliquus. The results showed that L-glufosinate-ammonium was more toxic to S. obliquus than rac-glufosinate-ammonium and caused more severe oxidative damage. The study also found that L-glufosinate-ammonium degraded faster than D-glufosinate-ammonium and no enantiomerization was observed.

Summary: Tetracycline antibiotics can have toxic effects on freshwater microalgae, but at lower concentrations, the microalgae are able to recover and show enhanced photosynthetic activities. The transcriptomic analysis revealed differentially expressed genes related to photosynthesis. This study provides insights into the environmental risk of Tetracycline antibiotics and their effects on photosynthesis.

Summary: This study assessed the impact of two commonly prescribed non-steroidal anti-inflammatory drugs on Daphnia magna, a species commonly found in freshwater ecosystems. It found that exposure to these drugs affected feeding behavior and key enzyme activities in the daphnids, and the effects were more pronounced in the transgenerational exposures. The study suggests that combining molecular and phenotypic markers of physiology in transgenerational studies is an effective way to understand the impact of pharmaceutical stressors.

Summary: Aquaculture facilities can contaminate aquatic environments with antibiotics, which can have negative effects on algae species. This study evaluated the toxicity of enrofloxacin on Scenedesmus obliquus algae. The results showed that enrofloxacin accumulated in the algae and inhibited their growth and photosynthesis. Furthermore, enrofloxacin disrupted the electron transport and carbon fixation processes in algae, posing a considerable risk to aquatic environments and potentially impacting human health.

Summary: Since 2019, the world has been greatly influenced by the successive waves of the COVID-19 pandemic. During this time, researchers have made discoveries about the structure, action, short- and long-term effects of the virus, and have developed treatments. While the pandemic has undoubtedly impacted people's lives, there is also growing attention on its effects on the environment. This review analyzed the use of non-steroidal anti-inflammatory drugs (NSAIDs) for treating SARS-CoV-2 symptoms, their effects on the human body and aquatic organisms, and their presence in the environment. The findings highlight the need for further research and report on the environmental impact of NSAIDs during the pandemic.

Summary: This study evaluated the food potential of Scenedesmus obliquus biomass obtained from photosynthetic cultures enriched with different concentrations of carbon dioxide (CO2). The results showed that higher concentrations of CO2 led to increased synthesis of amino acids and proteins in the cultures. In addition, higher concentrations of chlorophylls were found in cultures with higher CO2 levels, while carotenoid concentrations were higher in cultures with lower CO2 levels. Overall, the Scenedesmus obliquus biomass accumulated significant amounts of proteins, lipids, and pigments through photosynthesis.

Summary: Due to the escalating risk of plastic pollution, nanoplastics have received significant attention. A study examined the individual and combined effects of fluorescent polystyrene nanoplastics (FNPs) and diclofenac (DCF) on Scenedesmus obliquus. The toxicity of S. obliquus significantly increased upon exposure to DCF and FNPs, with oxidative stress being the major cause. When FNPs and DCF were mixed, a synergistic or antagonistic effect was observed depending on the concentrations. Oxidative stress parameters, antioxidant enzyme activity, and pigment content in the algae validated the cytotoxicity data. The study highlights the hazardous nature of nanoplastics and their co-exposure risks with pharmaceuticals.

Summary: The application of non-steroidal anti-inflammatory drugs (NSAIDs) in cancer therapy has been widely studied. This review summarizes the role of chronic inflammation in carcinogenesis and the anti-cancer activity of NSAIDs. However, the practical application of NSAIDs is hindered by individual side effects, particularly gastrointestinal toxicity. Strategies to reduce toxicity and improve efficacy are being investigated, including combinations with chemotherapeutic drugs and molecular hybridization with other active molecules.

Summary: NO2 emissions from wall-mounted gas stoves used for household heating have become a significant source of indoor pollution in Chinese urban areas. The high indoor concentration of NO2 poses potential health risks to residents. It is urgently necessary to establish relevant regulations and implement emission reduction technologies to reduce NO2 emissions from wall-mounted gas stoves.

Summary: This study investigates the relationship between dissolved organic matter (DOM) and Rare Earth Elements (REEs) in sediments from Yundang Lagoon, China. The results show four distinct fluorescent components, with protein-like substances being the most prevalent. Additionally, the total fluorescence intensity and LREE concentrations exhibit a synchronized increase from Outer to Inner to Songbai Lake core sediments. The findings demonstrate a strong correlation between DOM content and pollution levels.

Summary: The objective of this study is to incorporate soil hydraulic properties into the erodibility factor (K) of USLE-type models. By modifying and improving the existing equations for soil texture and permeability, the study successfully included information on saturated hydraulic conductivity (Ksat) into the calculation of K factor. Using the Random Forest machine learning algorithm, two independent K factor maps with different spatial resolutions were generated. The results show that the decrease in K factor values has a positive impact on the modeling of soil erosion rates.

Summary: The choice of workflow in wastewater surveillance has a significant impact on SARS-CoV-2 concentrations, while having minimal effects on HF183 and no effect on HAdV 40/41 concentrations. Certain components in the workflow can be interchangeable, but factors such as buffer type, chloroform, and homogenization speed can affect the recovery of viruses and bacteria.

Summary: Atmospheric PM2.5, which can generate reactive oxygen species (ROS), is associated with cardiorespiratory morbidity and mortality. The study found that both the mass concentration of PM2.5 and the DTT activity were higher during the heating season than during the nonheating season. Combustion sources were the primary contributors to DTT activity during the heating season, while secondary formation dominated during the nonheating season. The study also revealed that biomass burning had the highest inherent oxidation potential among all sources investigated.

Summary: In this study, inverse vulcanized polysulfides (IVP) were synthesized by reacting molten sulfur with 4-vinyl benzyl chloride, and then functionalized using N-methyl D-glucamine (NMDG). The functionalized IVP showed a high mercury adsorption capacity and a machine learning model was developed to predict the amount of mercury removed. Furthermore, the functionalized IVP can be regenerated and reused, providing a sustainable and cost-effective adsorbent.

Summary: This study investigated the presence of aluminum in human colon cancer samples and its potential association with biological processes involved in cancer progression. Aluminum was found in tumor areas of 24% of patients and was associated with epithelial to mesenchymal transition (EMT) and cell death. Additional analyses revealed higher tumor mutational burden and mutations in genes related to EMT and apoptosis in aluminum-positive colon cancers. Understanding the molecular mechanisms of aluminum toxicity may improve strategies for the management of colon cancer patients.
