This review meticulously examines the dynamics of river microbiomes, with an emphasis on the Ganges and Yamuna rivers of South Asia. These rivers are vital for both ecological and cultural landscapes and offer to understand the interaction between ecological and anthropogenic factors and their impact on microbial communities and activities. Ecological and hydrological factors such as seasonal changes, water flow and physico-chemical properties of rivers influence microbial diversity and abundance. The effect of heavy metals from industrial and agricultural sources on the river microbiome and how these pollutants modify microbial community structures and ecosystem health are not understood well yet. This underscores the need for sustainable water treatment and remediations for practical engineering solutions. The study reveals how these interactions, whether symbiotic or competitive, affect the composition and functionality of riverine microbial communities. An innovative aspect of our research is the potential of river microbiomes as indicators of urban sewage contamination. We demonstrate how microbial patterns can signal pollution levels, proving valuable for environmental monitoring, management and mitigation. A special attention to the role of microbes in river ecosystems' biogeochemical cycles has been paid to how these microbes contribute to nutrient recycling, organic matter decomposition and overall ecosystem productivity, underlining their crucial role in maintaining the aesthetic value of the river. Additionally, study evaluates the latest methodologies for analysing microbiome metagenomic data, including functional annotation and microbial community analysis techniques. Findings highlight the key importance of understanding river microbiomes for hydrology, ecology and microbiology researchers. © 2024 John Wiley & Sons Ltd.

Understanding the sources, mechanisms, and potential health impacts of volatile organic compounds (VOC) and secondary organic aerosols (SOA) is crucial for safeguarding human health, promoting sustainable industry and infrastructure practices, and addressing climatic challenges. These compounds originating from both anthropogenic and natural activities play a pivotal role in shaping air quality, climate dynamics, and public well-being. A comprehensive comprehension of their processes, interactions, and influence on atmospheric chemistry is imperative for devising effective strategies to mitigate associated health risks. This review comprehensively addresses the formation of biogenic and anthropogenic SOA, elucidates the intricate chemistry governing SOA generation, and expounds upon their far-reaching impacts. By encompassing diverse aspects such as tropospheric ozone, indoor and outdoor VOC and SOA formation, and the dynamic processes occurring during day and night cycles, this study facilitates a holistic understanding of the intricate interplay between VOC, SOA, and environmental dynamics, additionally underscores the importance of polycyclic aromatic hydrocarbons (PAHs) in this context. A deeper grasp of VOC and SOA sources, their transformation mechanisms, and the resulting implications will foster innovative solutions aimed at minimizing health risks, advancing sustainable industry practices, and driving climate action. This review delves into the multifaceted realm of VOC and SOA, highlighting their significance in achieving sustainable development goals (SDGs), particularly SGD-3 (Good Health and Well-being), 9 (Industry, Innovation, and Infrastructure), and 13 (Climate Action). © 2023, The Author(s), under exclusive licence to Springer Nature Switzerland AG.
