👉 Rivers' fumes refer to the pollutants and gases released into the water from various sources along their courses, including industrial discharges, agricultural runoff, sewage, and atmospheric deposition. These emissions can include heavy metals, chemicals, nutrients, and organic compounds that degrade water quality, harm aquatic ecosystems, and pose risks to human health. As these substances mix with the river water, they can lead to issues such as eutrophication, toxicity, and reduced oxygen levels, affecting fish and other wildlife. Monitoring and managing these fumes is crucial for maintaining the ecological balance and ensuring safe water for consumption and use.
