Kathmandu, March16, 2025 - A recent study conducted by Dr. Vikas Adhikari, Associate Professor at Kathmandu University, and his research team has revealed alarming levels of microplastics in bottled and jarred water sold commercially across Nepal. Published in the prestigious Springer Nature Journal, the study raises significant concerns about the potential long-term impacts on human health and the environment.
The researchers analyzed 56 water samples from 11 different brands collected from various districts in all seven provinces of Nepal. Their findings indicate that every sample tested contained microplastics, with bottled water averaging 232 microplastics per liter and jarred water averaging 286 microplastics per liter. The highest levels of contamination were reported in the Terai region, likely due to high temperatures and the chemical degradation of plastic containers.
Additionally, reused jars were found to have significantly higher concentrations of microplastics, underlining concerns about poor quality control and unsafe reuse practices. Dr. Adhikari emphasized that diverse sources contribute to microplastic contamination, including manufacturing processes, packaging materials, and environmental exposure.
Health and Environmental Implications
The study underscores the dire consequences of microplastic exposure for both human health and the environment. Microplastics can carry harmful chemicals and pollutants, which may lead to long-term health issues such as hormonal disruptions, immune system problems, and chronic diseases.
Environmentally, the proliferation of microplastics contributes to the broader issue of plastic pollution, affecting aquatic ecosystems and biodiversity.
Call for Urgent Action
Dr. Adhikari and his team have proposed several measures to address this growing crisis:
Improving Production Standards: Water bottling companies must adopt stringent quality control measures to minimize microplastic contamination during production.
Mandatory Quality Testing: Regular testing of packaged water for microplastic content should be enforced by regulatory authorities.
Public Awareness Campaigns: Educating consumers about the risks of microplastics and the importance of choosing safer alternatives.
Policy and Legal Reforms: The government must establish and enforce stricter regulations on plastic packaging and water quality standards.
This groundbreaking study serves as a wake-up call for Nepal to prioritize clean water standards and tackle the growing menace of microplastic pollution. Without immediate action, the health and environmental consequences could escalate, impacting future generations.
