1. Phase transformation and surface chemistry of secondary iron minerals formed from acid mine drainage
Sammanfattning : The mining of sulphidic ore to extract metals such as zinc and copper produces huge quantities of waste material. The weathering and oxidation of the waste produces what is commonly known as Acid Mine Drainage (AMD), a dilute sulphuric acid rich in Fe(II) and heavy metals. LÄS MER
2. Lead(II) as a Tool for Probing RNA Structure in vivo
Sammanfattning : Chemical modification and limited enzymatic hydrolysis are powerful methods to obtain detailed information on the structure and dynamics of RNAs in solution. In the work presented here I have taken advantage of the properties of the divalent metal ion lead(II) to establish it as a new probe for investigating the structure of RNA in vivo. LÄS MER

5. Lead exposure in indigenous children of the Peruvian Amazon : seeking the hidden source,venturing into participatory research
Sammanfattning : Introduction. In 2006, a Peruvian environmental agency reported the presence of elevated blood lead levels (BLLs) in indigenous communities of the Corrientes river basin. This is a territory in the Peruvian Amazon where oil activity has been associated with serious environmental effects, with impact on an ongoing social conflict. LÄS MER
