Global Advances in Selenium Research from Theory to Application Proceedings of the 4th International Conference on Selenium in the Environment and Human Health 2015

    The 4th International Conference on Selenium in the Environment and Human Health was held 18-21 October 2015 in São Paulo, Brazil. This conference provided an effective scientific communication platform for researchers in different disciplines worldwide to elucidate and better understand those complex roles of Se as both essential nutrient and environmental contaminant. This proceedings volume includes 98 peer-reviewed extended abstracts prepared by Se researchers from 28 countries. These most recent Se research studies address inter-relationships between the geological and atmospheric environment, agricultural food and selenium-biofortified food crops, human and animal health impacts, and genetic, biochemical, and cell and molecular activities. This book presents a unique myriad of Se research to further our international understanding of the role of Se in the context of biochemistry, food chain transfer, and health-related issues.

    Dr. Gary Bañuelos is a Plant/Soil scientist at the U.S. Department of Agriculture-Agricultural Research Service, Water Management Research Unit, Parlier, California, and adjunct professor at the University of California and California State University-Fresno. Dr. Bañuelos began work with "green technology" with Professor H. Marschner in Germany and focuses his research on the phytoremediation of soils and waters laden with selenium, boron, and salinity in California, and on integrated production of innovative biofortified and bio-based products (e.g., biofuel, Se-enriched feeds, and organic fertilizer/herbicides). He strives for creating a sustainable green strategy for managing trace elements in the United States and in other parts of the world. Dr. Bañuelos is the principle author of over 140 refereed technical journals on the topic of phytoremediation and has co-edited four books. He received his Bachelor of Arts degree in German from California State University, Bachelor of Science in Crop Science, and Master of Science degree in International Agriculture from California Poly-Technical University, while his diploma in Plant Biology was earned at the University of Tubingen, Germany, and doctorate in Agriculture/Plant Nutrition at Hohenheim University, Germany, as a U.S. National Science Foundation Fellow.

    Dr. Z.-Q. Lin is a Professor in the Department of Biological Sciences and the Director of the Environmental Sciences Program at Southern Illinois University - Edwardsville in Illinois. Dr. Lin received his BS degree in Environmental Biology from Liaoning University in China, MS degree in Pollution Ecology from Chinese Academy of Sciences, and Ph.D. degree in Renewable Resources from McGill University in Canada. He was a post-graduate researcher on biogeochemistry of selenium at University of California - Berkeley. His research is related to the biogeochemistry of environmentally important trace elements, with a special focus on biological accumulation, transformation, and volatilization processes of selenium in the air-water-soil-plant system. He is the author or coauthor of over 65 peer-reviewed articles published in scientific journals, proceedings and monographs.
