Himalayan ecology in danger: Microplastics found in Yamunotri glacier and 170 km stretch of Yamuna River
A new study by Dehradun-based Doon University has found dangerous microplastics in the Yamunotri glacier and a 170 km stretch of the Yamuna river. The findings raise serious concerns for Himalayan ecology, water quality, and the future of communities dependent on the river.
Dehradun: The fragile Himalayan ecosystem has received a major warning. A research study conducted by Doon University has revealed the presence of harmful microplastics in the Yamunotri glacier and across a 170 km stretch of the Yamuna river. The discovery highlights the growing threat of pollution in one of India’s most sacred and vital rivers.
Researchers collected samples from the Yamunotri glacier, the origin of the Yamuna, and from different points along the river. The study confirmed that microplastics—tiny plastic particles less than 5 millimeters in size—have spread across the glacier and downstream areas. These particles are invisible to the naked eye but pose serious risks to water quality, aquatic life, and human health.
Glaciers are considered pristine sources of freshwater
The findings are alarming because glaciers are considered pristine sources of freshwater. The presence of microplastics here indicates that pollution has reached even remote and high-altitude regions of the Himalayas. Dr. Surendra Singh Suthar of Doon University led the Yamunotri microplastic study, identifying harmful polymers like polypropylene and polyethylene, warning of serious threats to Himalayan ecology, river health, and water quality.
The study revealed the presence of polypropylene, polyethylene, polystyrene, and polyester microplastic polymers, commonly used in packaging and textiles, raising serious concerns for Himalayan ecology and downstream water quality.
Lifeline for millions of people across northern India
The Yamuna River is a lifeline for millions of people across northern India. It provides drinking water, irrigation, and supports biodiversity. Pollution at its source threatens not only the ecology of the Himalayas but also communities downstream.
Microplastics can enter the food chain through fish and other aquatic organisms. They also carry toxic chemicals, which can harm human health. Scientists warn that if unchecked, this pollution could worsen water scarcity and damage fragile mountain ecosystems.
Causes of pollution
Experts believe that tourism, improper waste management, and plastic use in high-altitude areas are contributing to the spread of microplastics. Pilgrimage sites near Yamunotri attract thousands of visitors each year, and plastic waste often ends up in rivers and glaciers.
Climate change is another factor. As glaciers melt faster, pollutants trapped in ice are released into rivers, increasing contamination levels.
Environmentalists and researchers are urging immediate steps
Environmentalists and researchers are urging immediate steps to tackle the issue. They recommend stricter waste management in pilgrimage and tourist areas, banning single-use plastics, and raising awareness among local communities. The study also calls for more monitoring of Himalayan rivers and glaciers to understand the scale of pollution and its long-term impact.
It is a wake-up call
The presence of microplastics in the Yamunotri glacier is a wake-up call. Protecting the Yamuna at its source is crucial for safeguarding water quality, ecology, and the health of millions who depend on it. Without urgent action, the pollution crisis could deepen further.
