Enhanced Arsenic Contents in Spring Water within the Engadine Valley (South-eastern Switzerland; Canton of Graubünden) by Werner Balderer in An archive of organic and inorganic chemical sciences in Lupine Publishers

Near the city of St. Moritz (Figure 1, Canton of Graubunden, Switzerland) were measured enhanced arsenic concentrations in the spring water which is used for drinking water. The investigated area is mainly formed of silicate rocks, which regionally contain arsenic-bearing minerals such as pyrite and haematite. The soil percolation water is contaminated with arsenic up to 120 micrograms per litre. These observed concentrations are largely above the internationally recommended limiting value of 10|ig/l. The sources of arsenic are supposed to be related to the occurrence of pyrite iron ore minerals and arsenic sulphur-minerals, such as arseno-pyrite (FeAsS) and CoAsS, within the crystalline rocks

Biological Studies, Synthesis, Structural, Spectral Characterization and Co-Ordinate Mn (II), Fe (II), Zn (II) (II) Complexes Containing 2-Hydroxy-1- Naphthaldehydeand n,n’-Dimethyl-1,3-Propanediamine by Kadhiravan S in An archive of organic and inorganic chemical sciences in Lupine Publishers

A new Manganese (II), Iron (II), Zinc (II), complex, has been and characterized by elemental analysis, UV-Vis, FT-IR and Binding of this Mn (II), Fe (II), Zn (II) complex with calf thymus DNA was investigated by UV-Visible absorption, fluorescence spectroscopy techniques. The intrinsic binding constants Kb of complex with CT-DNA, BSA obtained from UV-Vis absorption studies were 1.75X1 05,1.98X105and2.38X105M-1.
