Research Insights and Detection Techniques
Sharing insights from his research, Dr. Tarafdar introduced a plastic-degrading bacterium, Bacillus siamensis ATKU1, capable of breaking down low-density polyethylene (LDPE). He also discussed a dye-based detection technique his team developed for identifying microplastics in soil and food samples.
Significantly, Dr. Tarafdar revealed the presence of microplastics in intravenous (IV) fluid systems, raising new biomedical safety concerns. This finding underscores the urgent need for stricter monitoring and innovative solutions in healthcare systems.
Focus on Health and Policy
Prof. Alok Sinha, Head of the ESE Department and coordinator of the program, welcomed the keynote speaker and stressed the rising risks posed by microplastics. He called for interdisciplinary research and policy integration to manage this global challenge effectively.
Dr. Avanika Chandra, Information Officer, introduced Dr. Tarafdar, outlining his expertise in microbe–plastic interactions, pollutant biodegradation, and health risk assessment of emerging contaminants.
