    Abstract : 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. READ MORE

  2. 2. Lead(II) as a Tool for Probing RNA Structure in vivo

    Author : Magnus Lindell; Gerhart Wagner; Roland Hartmann; Uppsala universitet; []

    Abstract : 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. READ MORE

    Abstract : 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. READ MORE
