Geochemical, Geoecological and Sedimentological Analysis

 



Research mission: geochemistry, biology, geo-ecology, palaeontology, grain-size, mineralogical and geotechnical studies.



Laboratory analyses for:

  • Heavy metals in water and sediments (Cu, Pb, Zn, Cr, Ni, Cd, Co, Sr, Rb, Ba, Zr, As), by AAS and / or XR fluorescence;
  • Nutrient contents in water samples: P04, N02, NO3, dissolved silica, by standard HACH methods;
  • Major chemical components in water and sediments: CaC03, TOC, Fe2O3 total; Ti02, MnO;
  • spectrophotometry UV-VIS chlorophyll analyses
  • Physical-chemical parameters for water sample testing: Dissolved oxygen (DO), Oxygen contents (%), pH, Eh, Conductivity, Salinity, Total Dissolved Solids (TDS), by electrochemical methods;
