Summary: Light-oxygen-voltage (LOV) proteins, a type of optogenetic systems, can produce singlet molecular oxygen. SOPP3, a re-engineered version of miniSOG, has a high yield of singlet molecular oxygen production, but causes FMN bleaching when localized in a cell. By replacing an amino acid, the lifetime and yield of FMN can be increased. Despite the bleaching, SOPP3 can induce morphological changes in cells.

Summary: Amphipathic perylene derivatives are effective antiviral compounds that target the viral envelope and act as fusion inhibitors. They damage the viral envelope using lipophilic perylene and singlet oxygen generated by light. Short alkyl chains contribute to strong antiviral activity, while longer alkyl chains reduce activity due to increased lipophilicity and aggregation.

Summary: The study found that a BODIPY derivative showed a significant enhancement in singlet oxygen sensitization quantum yield with the decrease of solvent dielectric constant. Triplet state formation for the derivative was mediated by intramolecular charge transfer state in toluene, while hindered by fast recombination of the ICT state in polar solvents. The photoinduced dynamics of the BODIPY derivatives were characterized from femtosecond to nanosecond time scale using pump-probe transient absorption spectroscopy.

Summary: Heavy-atom-free photosensitizers, such as BODIPY-based orthogonal dimers with proper formyl functionalization, have the potential to visualize and kill tumor cells through fluorescence signaling and photodynamic therapy. The photophysical properties of formyl-functionalized BODIPY dimers were analyzed, indicating that their dual performance of fluorescence and singlet oxygen generation can be modulated by the formyl functionalization at specific positions. Regioselective formylation was proposed as an effective tool to balance fluorescence, singlet oxygen generation, and intramolecular charge transfer for photo-theragnosis.

Summary: This study investigates the influence of Cu(II) on the photolytic fate of Tetracycline (TC) under UV irradiation. Cu(II) significantly promotes the removal of TC and affects both direct and indirect photolysis of TC. Cu(II) induces the formation of singlet oxygen and hydroxyl radicals, and prefers to form TC-Cu(II) complexes. The TC-Cu(II) complexes are more vulnerable to ROS attack, promoting TC degradation. Cu(II) also changes the photolysis path of TC and alters the toxicity of the products. This study provides new insights into the environmental fate of antibiotics and has implications for wastewater treatment in the pharmaceutical and aquaculture industry.

Summary: Recent studies have indicated that microplastic pollution can exert additional stress on amphibian populations. However, our understanding of the effects of microplastics on amphibians, especially in combination with other emerging pollutants, is limited. This study aimed to assess the potential toxicity of polyethylene microplastics (PE-MPs), alone or in combination with a mixture of pollutants, on the health of Physalaemus cuvieri tadpoles. The results showed that exposure to the combination of PE-MPs and pollutants induced enhanced stress responses in tadpoles, although the uptake and accumulation of PE-MPs in the animals was reduced. This study provides new insights into the risks posed by microplastics coexisting with other pollutants in aquatic environments.

Summary: The objective of this study was to assess micropollutant removal during ozone disinfection of wastewater, utilizing targeted and untargeted screening analyses. Effluents from two wastewater treatment plants were treated with ozone at various doses and analyzed using gas chromatography coupled with Orbitrap High-Resolution Mass Spectrometry. The removal of different chemical families was evaluated in relation to the level of Escherichia coli and the total removal of coliforms. The proposed methodology aims to provide a new protocol for the careful evaluation of ozonized wastewater effluents for disposal and reuse.

Summary: Cresols are commonly found in freshwater systems and are used as disinfectants. However, their long-term toxicity effects on reproduction and gene expression patterns of aquatic species are not well understood. This study aimed to investigate the chronic toxic effects of cresols on reproduction and gene expression using D. magna, and also examined the bioconcentration behavior of cresol isomers. The results showed that cresols had negative effects on offspring quantity and reproduction delay, but did not significantly affect body weight and gene transcription in Daphnia. The bioconcentration experiments indicated that cresol isomers are unlikely to accumulate in aquatic species.

Summary: Carcinogenic metals, particularly chromium (Cr) and its derivatives, including Cr(VI)-induced, have widespread distribution and pose a concern for adverse environmental and human health effects. They cause DNA epigenetic alterations resulting in heritable changes in gene expression. This review discusses the role of Cr(VI) in epigenetic changes, highlighting the importance of considering epigenetics as a possible mechanism underlying Cr(VI) toxicity and cell-transforming ability. More clinical and preventative measures are needed to better understand the toxicity and safeguard employees against cancer.

Summary: Contaminants of emerging concern and other chemicals are widely present in the environment, and they can induce various effects at concentrations/doses smaller than the toxicological threshold. These low-dose effects pose challenges for wastewater reuse and reclamation, and stakeholders have made efforts to address this issue. To effectively tackle the low-dose issue, the improvement of treatment/remediation sites, better control/prevention of chemical release, and involvement of citizen-science approach should be considered.

Summary: During the COVID-19 pandemic, the increased use of disposable face masks has led to a significant environmental burden. This critical review discusses the degradation and toxicity of face mask contaminants and emphasizes the need for more research in this area. The lack of studies on biodegradation and ecotoxicity, as well as the uncertainties in experimental procedures, hinder the comparison with conventional plastic debris. Further studies on the abundance and composition of face mask-released contaminants and the development of methodological strategies are crucial to understand their environmental impact.
