Description
This book presents contributions by experts from diverse disciplines, estimating the global levels of biogeogenic and anthropogenic emissions of organometal(loid) compounds, and thus presenting insight into processes which influence the genesis, as well as the distribution and stability of these species and their interaction with each other and other matrix compounds. The authors evaluate identify potential “hot spots” of organometal(loid)s, which can negatively influence ecosystems and human health. 1 Organometallic compounds in the environment: An overview.- 2 Advances in analytical methods for speciation of trace elements in the environment.- 3 Analytical strategies for arsenic speciation in environmental and biological samples.- 4 Occurrence and speciation of arsenic, antimony and tin in specimens used for environmental biomonitoring of limnic ecosystems.- 5 Methylated metal(loid) species in biological waste treatment.- 6 Volatile mercury species in environmental gases and biological samples.- 7 Biovolatilisation of metal(loid)s by microorganisms.- 8 The Effect of Phosphate on the Bioaccumulation and Biotransformation of Arsenic(V) by the Marine Alga Fucus gardneri.- 9 Molecular modeling studies of specific interactions between organometallic compounds and DNA.- 10 Organometal(loid) compounds associated with human metabolism.- 11 Genotoxicity of organometallic species.- 12 Current aspects on the genotoxicity of arsenite and its methylated metabolites: Oxidative stress and interactions with the cellular response to DNA damage.- 13 Cytogenetic investigations in employees from waste industries.- 14 Neurotoxicity of metals.- 15 Actions of metals on membrane channels, calcium homeostasis and synaptic plasticity.- 16 Effects of organometal(loid) compounds on neuronal ion channels: possible sites for neurotoxicity.- 17 Panel discussion: Analytical aspects Discussion Session on “Speciation Analysis of Environmental Samples”.- 18 Panel discussion: Toxicological Aspects Discussion Session on “Toxicological Aspects of Alkylated Metal(loid) Species”.- Resum.
