Chasicó Lake is The main water body in the south west of the Chaco-Pampean plain.It shows some differences from the typical Pampean shallow lakes,such as high salinity and high arsenic and fluoride levels.The aim of this paper is to analyze the trace elements [arsenic(As),fluoride(F−)and vanadium(V)] present in Chasicó Lake. Surface and ground water were sampled in dry and wet periods,during 2010 and 2011.Fluoride was determined with a selective electrode.As and V were determined by Inductively Coupled Plasma Atomic Emission Spectroscopy(ICP-AES).Significant correlation in surface water was only found for As and F−(r=0.978,p
