Research Details

Welcome!

I am a Prime Minister's Research Fellow (January 2021- Present) in the department of Chemical Engineering, Indian Institute of Technology Kharagpur, working under Dr. Amar Nath Samanta . My broad area of research is Pollution Control. I joined the Ph.D. program at IIT Kharagpur in July 2019. Later it is converted to PMRF category under 2020 December cycle.

Roll No.- 19CH91R10

Among the numerous emerging water pollutants, pharmaceuticals are one of the most important categories. Pharmaceuticals include antibiotics, analgesics, steroids, antidepressants, antipyretics, stimulants, analgesics, hormones, anti-inflammatory drugs, ß-blockers, lipid regulators, contrast agents, and impotence drugs. At present, drug residues are found in almost all environmental substrates on every continent, including surface water (lakes, rivers, streams, estuaries, and sea water), groundwater, sewage treatment plant effluent and sludge. The persistence and potentially toxic effects of these residual drugs, as well as their continuous discharge from waste-water to water sources, poses long-term potential risks to aquatic and terrestrial organisms. According to a recent report, 100,000–200,000 tons of antibiotics are used worldwide every year resulting in a large number of antibiotic residues in water. Antibiotics may cause long-term irreversible changes to the microbial genome and make the microbes resistant, even at low concentrations. Therefore, it is important to treat residual pharmaceutical wastewater.
