Summary: This review article summarizes the current status and future opportunities of surface-enhanced Raman spectroscopy (SERS) for the analysis of emerging contaminants (ECs) in drinking water. The working principles of SERS are introduced, and a comparison between SERS and liquid chromatography-tandem mass spectrometry is made. Strategies for designing effective SERS sensors for EC analysis are discussed based on different categories of ECs. The discussions are guided by advancements in SERS technology and drinking water regulatory policies.

Summary: The occurrence of various organic contaminants in the aquatic environment, including pharmaceuticals, pesticides, and industrial compounds, as well as xenobiotic degradation products, has been elucidated in this study. Some compounds were found to have high concentrations, and prosulfocarb, fluopyram, and tris(3-chloropropyl) phosphate were the most common and widely distributed contaminants. Nearly half of the sampling sites contained over 30 different compounds. Non-target screening played a significant role in revealing the chemical composition of surface water and potential sources of contamination.

Summary: This study combines column experiments and reactive transport simulations to assess CO2-sediment interactions in shallow groundwater aquifers. Carbonate mineral dissolution is identified as the most significant reaction following CO2 intrusion, with cation exchange playing a key role in controlling trace metal release. Most trace metals show short-term release with low risk to overlying USDW quality, but some metals like Mn and U exhibit long-term potential concerns.

Summary: Pharmaceutical pollutants (PPs) from various sources are considered emerging pollutants (EPs) affecting river health by negatively impacting the biotic diversity. A River Health Index (RHI) based on six Indicator Group Scores (IGS) is used to assess river health, with Dissolved Oxygen Related Parameters (DORP), Nutrients (NT), and PPs identified as causative agents. The study highlights the inadequate effectiveness of current wastewater treatment technologies in removing PPs, which pose a risk to aquatic organisms and river health.

Summary: To assess the suitability of sediments for ocean disposal, a defensible sediment quality guideline value for dioxin-like compounds was required. The use of a tissue residue approach based on equilibrium partitioning between sediment and organisms determined an adequate conservative value of 70 pg TEQ/g dry weight. This approach can be applied internationally in similar situations.

Summary: Autophagy is a crucial cellular system that protects cells from various stresses. Environmental contaminants can influence autophagic flux in different ways, either enhancing, preventing, or converting its function. Increasing autophagy can improve stress resistance, while suppressing it can increase or decrease toxicity. Selective autophagy is utilized to eliminate harmful substances without damaging cytosolic components. Understanding the impacts of environmental exposure on autophagy provides new approaches for risk assessment and protection against environmental contaminants.

Summary: This study investigated the impact of adding wheat straw on the anaerobic co-digestion of leather waste and its biogas production. The results showed that alkali treatment significantly increased the cellulose content of wheat straw, but inhibited methanogenesis, resulting in the lowest biogas production. However, the highest biogas yield was achieved when wheat straw was pretreated with acid, indicating its potential as an alternative for co-digestion.

Summary: This study evaluated the agronomic value and phytotoxic effect of liquid digestate obtained from the anaerobic co-digestion of tannery waste. The results showed that the liquid digestate had a bio-stimulating effect on plant development, similar to mineral fertilizers. The analysis of soil samples indicated that the liquid digestate provided the same nutrients as other fertilizers and did not negatively affect soil organic matter or cause metal accumulation.
