Abstract: This talk discusses the research highlights in hydro-geochemistry, focusing on trace element toxicity in India’s groundwaters. Arsenic contamination in groundwater is a major public health issue in Southeast Asia, affecting over 150 million people. Approximately 20% of India's land area encompassing 20 states faces alarming levels of arsenic contamination in its groundwater, putting over 250 million people at risk. In India, groundwater contamination includes not only arsenic but also other geogenic contaminants like selenium and uranium. This talk further explores the mechanisms of arsenic contamination, including its mobilization, subsequent fate, and health risks associated with consuming contaminated food and water. His presentation will also encompass the impact of redox processes on pollutant speciation and bioavailability, addressing both short-term and long-term perspectives. This also incorporates his future interests in further developing research skills by integrating cutting-edge research techniques, such as coupling various advanced instruments (e.g., HPLC/IC with ICP-MS) in speciation to understand complex pathways of contamination and utilizing environmental isotopes to investigate aquifer interactions.
