Tarit Roychowdhury

Listed in the top 2% scientists in the world, as per the statistical evaluation records of Stanford University, USA, 2022. PhD in Science with 27 years experience in research on Environmental Analytical Chemistry Our current topics of research interest involve 1) The magnitude and calamity of arsenic and fluoride-contamination in groundwater from West Bengal and other parts of GMB basin. 2) Detailed studies on the presence of other groundwater contaminants like nitrate and radioactive element like uranium etc. 3) Distribution of toxic contaminants in groundwater and soil-plant system. 4) Source and mobilization of contaminants from source to aquifer. 5) Human health effect and risk assessment (acute and chronic toxicity). 6) Food chain contamination through irrigated groundwater with special reference to rice grain arsenic contamination, phase-wise distribution in paddy field with seasonal variations. 7) Remedial measurements including reduction of arsenic and fluoride from contaminated groundwater and approaches for arresting the contaminants in soil-plant system to restrict its entry in food chain using several coagulants, adsorbents like different organic amendments, nano-particles, biochars, nano-biofertilizers and seed priming with different amendments etc. Our research studies include different branches of Science and Technology including Environmental Science, Environmental Engineering and Management, Environmental Chemistry, Geology, Microbiology, Botany, Anthropology, Agricultural Science and Engineering, Biology, Sociology, Civil and Chemical Engineering, Water Resource Engineering, Statistics, Economics etc. BRIEF OVERVIEW Expertise in Environmental Analytical Chemistry Research and Teaching in graduation and post-graduation level in Chemistry/Engineering Chemistry/Environmental Chemistry/Environmental Biotechnology/Industrial Safety & Environmental Management with special reference to the subjects like Environmental Pollution, Solid and Hazardous Waste Management, Pollution Sources and Measurements and Sessional Work (Water/Waste Water/Soil/Sediment Quality Parameters).
