This edited book is based on the accepted papers for presentation at the 1st MedGU Annual Meeting, Istanbul, 2021. With two parts spanning a large spectrum of environmental, geomorphological and geoarcheological topics and a third part on caves and karst, which includes research studies gathered on the occasion of the International Year of Caves and Karst (2021), this book presents a series of newest research studies that are nowadays relevant to Middle East, Mediterranean region, and Africa.The book gives a general overview on current research, focusing on geoenvironmental issues and challenges in environmental management in the Middle East and Mediterranean region and surrounding areas. It offers a broad range of recent studies that discuss the latest advances in geomorphology, landslides, soil science, paleoclimate, and geoarcheology. It also shares insights on cave and karst studies including speleology, cave and karst explorations, geomorphology, hydrogeology,geoethics, prehistoric eras in karst, geotectonics, and the nexus between human activities and karst sustainability.

Now in its updated second edition, this book describes emerging chiral environmental pollutants and their importance in environmental and human toxicology, as well as enantiomer selective separation and analytical methods. Compared to the first edition from 2001, the book has been completely restructured and a wealth of new material has been added to account for new developments. The book reports on the modern enantiomer selective separation methods, including enantio-selective chromatography techniques, which have even been successfully tested in space during the ESA Rossetta mission. The authors clearly outline why the topic of chiral environmental pollutants has become even more important: many new chiral compounds have been released in recent years (e.g. as new pharmaceuticals or agrochemicals), and traces of these compounds can now be found in the environment. The authors explain that (and how) chirality can be a very important feature for the bioactivityof anthropogenic pollutants. In this book, readers find an introduction to the topic, including all important aspects, from the introduction of new enantiomer selective analytical methods, and of emerging chiral environmental pollutants, to aspects on environmental and human toxicology and exposure, risk assessment, and aspects on climate change as well as other new aspects on chirality in the environment. The book is thus a must-read for everybody working in the field of chiral environmental pollutants, but it is also beneficial for teaching purposes in specialized post-graduate courses in advanced analytical chemistry, pharmaceutical analytics, or environmental chemistry.

The knowledge of metal ion speciation is essential for predicting the exact toxicities of metal ion species in the environment. Metal ions can exist in various oxidation states, each of which possesses different physical and chemical properties as well as exhibit varying toxicities. Often, toxicity data is unreliable because it is based on metal io
