【 摘 要 】

Major element chemistry of water samples in Ierissos gulf basin is dominated by Ca2+, Mg2+and HCO3-ions. Water rock interaction is an important mechanism in the mineralization of waters. A link between Skouries and Gomati samples (Mg-HCO3) was detected reflecting the well documented M. Panagia-Gomati fault. In Neochori and M. Panagia samples were identified fluids with different origin. Regarding surface waters, extended bicarbonates action of meteoric waters and reductive conditions, probably control As concentration in surface water. Generally, surface waters in Kokkinolakas basin exceed the WHO limits for As, Sb, Cr, Ni, Cd, Pb, Mn, Fe in great rates as natural immobilization mechanisms are suspended.
