Arsenic Monitoring, Removal and Remediation discusses methods for determining arsenic levels in the environment and removing arsenic pollution. Chapters in the first section comment on the principal methods for arsenic determination in environmental samples with emphasis on sample pretreatment, extraction, separation, and method validation techniques for speciation analysis. Attention is paid t…
The spatial variability of dissolved arsenic (As) concentrations in aquifers was studied near Ha Noi, Vietnam. The goal was to identify major geochemical, sedimentological and hydrochemical differences between high and low As regions. Also, the behaviour of As and other elements during sequential extractions was characterized with micro synchrotron XRF analysis. Based on the results a conceptua…
Wie ist es zu erklären, dass sich die bewaffneten Repressalien den Normierungsbemühungen seit dem 19.

Today's problematic environment–human interaction needs contemporary knowledge to address dryland complexity. Physical dimensions in arid zones—land systems, climate and hazards, ecology—are linked with social processes that directly impact drylands, such as land…
