Talk title: Assessing arsenic ecotoxicity in tropical soils for regulatory purposes: which endpoints are more appropriate?
Dr. Luiz Roberto Guimarães Guilherme is Professor of Soil Chemistry at the Soil Science Department, Federal University of Lavras, Brazil. His early career work has been dedicated to increasing fertilizer use efficiency for increasing agricultural productivity, with direct effects on improving soil fertility, crop yield, and economic sustainability of Brazilian agriculture. Currently, Luiz’s research/work has been focusing on the fate of trace and rare earth elements in agro-ecosystems, as well as in mining areas, two subjects of major social/economic/environmental importance in the State of Minas Gerais, Brazil. Professor Luiz Guilherme is the PI of a Research Network (Recuperamina) that deals with environmental impacts of mining/smelting activities and a leading researcher in the fate/toxicity of arsenic in mining and agricultural areas in Brazil. His research group did a pioneer work on ecotoxicity of As in soils, as well as on bioaccessibility of As in soils/sediments/tailings of the biggest gold mine in Brazil. Luiz is also the PI of an important Research Network (AgroMetals) that studies trace elements - As included - in Brazilian Agroecosystems (soil, agricultural inputs, and final agricultural products).
