Rising Concerns Over Microplastic Contamination in Indian Bottled Water and Regulatory Gaps
Scientific studies have revealed significant microplastic and nanoplastic contamination in bottled water across India, including major cities like Mumbai and coastal Andhra Pradesh. These particles, smaller than five millimetres, can carry toxic additives like phthalates and antimony that leach from plastic containers, especially when exposed to heat. Current regulatory standards by FSSAI and BIS focus primarily on pathogens and do not include testing for microplastics or long-term chemical exposure. The article advocates for strengthening municipal water supplies and updating regulatory frameworks to include routine testing for plastic-derived contaminants to protect public health.
Key Points
- Microplastics are plastic particles smaller than five millimetres that can bypass biological barriers and carry toxins.
- Leaching of chemicals like antimony and phthalates increases when plastic bottles are stored in direct sunlight or high temperatures.
- Current BIS and FSSAI standards lack protocols for monitoring microplastics and nanoplastics in packaged drinking water.
- A study in Nagpur found microplastic concentrations ranging from 72 to 212 particles per litre in sampled brands.
Exam Facts
- FSSAI stands for Food Safety and Standards Authority of India.
- BIS stands for Bureau of Indian Standards.
- Microplastics are defined as plastic particles smaller than 5mm in size.
