Dissolved organic matter and water age modulate heavy metal(loid)s distribution in the Yarlung Tsangpo River, Tibetan Plateau

Key Points

• Heavy metal distribution is notably affected by dissolved organic matter levels.
• The study identifies variations in water age and its impact on metal concentrations.
• Analysis of water samples from the Yarlung Tsangpo River indicates complex interactions among variables.
• Results suggest ongoing monitoring is crucial for understanding river health and metal pollution.
