<\/em><\/strong><\/p>\n\n\n\n The 151st colloquium on environment held: advancing solutions to arsenic contamination<\/strong><\/p>\n\n\n\n The 151st Colloquium on Environment<\/strong>, hosted by the Mei Laboratory<\/strong>, was held on April 16, 2026<\/strong>, at the GSES Ecolab 4th Lecture Room. The event featured Prof. Chien-Yen Chen (PhD)<\/strong> of National Chung Cheng University, Taiwan, a leading expert in environmental geochemistry and arsenic research.<\/p>\n\n\n\n The colloquium was attended not only by members of the Mei Laboratory, but also by participants from Iizuka Laboratory, along with other interested researchers and students across the Graduate School of Environmental Studies (GSES), reflecting strong interdisciplinary engagement.<\/p>\n\n\n\n In his lecture, \u201cFrom Arsenic Cycling to Sustainable Remediation: Integrating Microbial Processes, Geochemistry, and Green Materials,\u201d<\/strong> Prof. Chen presented a comprehensive yet grounded perspective on one of the most persistent global environmental challenges\u2014arsenic contamination in groundwater<\/strong>.<\/p>\n\n\n\n Drawing from extensive fieldwork in Taiwan and international collaborations, Prof. Chen illustrated how arsenic mobility and toxicity are shaped by the interplay of redox conditions, geological settings, and microbial activity. His discussion moved beyond theory, connecting environmental processes to real human health impacts, including chronic exposure risks linked to contaminated drinking water.<\/p>\n\n\n\n A notable aspect of the lecture was its integration of environmental monitoring and human biomonitoring. Case studies from Taiwan\u2019s groundwater and geothermal systems, alongside research in India using hair, nail, and urine samples, shows the direct relationship between environmental arsenic levels and human exposure.<\/p>\n\n\n\n Prof. Chen also emphasized forward-looking solutions, highlighting sustainable remediation strategies such as; (1) Microbially driven mineralization processes and (2) Iron-based nanomaterials for arsenic removal. These approaches reflect a shift toward integrated, scalable, and environmentally conscious technologies.<\/p>\n\n\n\n Student reflections (Mei-Laboratory)<\/strong><\/p>\n\n\n\n Q: What concept or idea from the lecture did you find most interesting or impactful, and why?<\/strong><\/p>\n\n\n\n Liu-san (D2, China)<\/strong><\/p>\n\n\n\n \u201cProf. Chen\u2019s biomonitoring research was particularly compelling. The study showed that arsenic concentrations peak in the 20\u201360 age group, significantly higher than other cohorts. I am interested in whether this trend is related to metabolic activity\u2014such as higher basal metabolism or greater water intake\u2014leading to increased internal exposure and incorporation into keratinized tissues.\u201d<\/p>\n<\/blockquote>\n\n\n\n Q: How does the lecture relate to your current field of study or research interests?<\/strong><\/p>\n\n\n\n Alam-san (M2, Indonesia)<\/strong><\/p>\n\n\n\n \u201cThis lecture is highly relevant to my research on arsenic phytoremediation using Pteris vittata<\/em>. Prof. Chen clearly explained arsenic contamination pathways and its impact on human health, as well as strategies to address it. I gained valuable insights into arsenic dynamics under different geochemical conditions, such as Eh and pH, and current remediation technologies.\u201d<\/p>\n<\/blockquote>\n\n\n\n Q: Given Prof. Chen\u2019s lecture, what key points did you learn, and how can these help your studies or academic development?<\/strong><\/p>\n\n\n\n Choity-san (M1, Bangladesh)<\/strong><\/p>\n\n\n\n \u201cThe seminar emphasized arsenic cycling and the role of redox conditions, microbial activity, and geochemical factors in controlling its mobility and toxicity. I learned how microorganisms drive metal transformations and contribute to sustainable remediation. These concepts are highly relevant to my studies and will help me better understand metal mobility and microbial influences in soil systems.\u201d<\/p>\n<\/blockquote>\n\n\n\n The colloquium provided not only scientific insights but also a broader perspective on how interdisciplinary approaches\u2014linking geochemistry, microbiology, and material science\u2014can contribute to solving real-world environmental problems.<\/p>\n\n\n\n For more information about the event, please visit:<\/p>\n\n\n\n https:\/\/www.kankyo.tohoku.ac.jp\/event\/e20260416.html<\/a><\/p>\n\n\n\n To learn more about
