The aim of the study is to determine the distribution of trace and major elements in the water and in the sediments of the south part of the Bacalar Lagoon and to identify the sources of the trace elements and their changes over time. The lagoon is not affected by present-day seawater intrusion.
Water column and sediment geochemical analyses performed in Bacalar Lagoon show clear spatial distribution of different parameters. The saturation index of the water column indicates three main groups: 1 a zone oversaturated with regard to aragonite, calcite and dolomite; 2 an undersaturated area where all three minerals are dissolving; and 3 an area with calcite equilibrium and undersaturation with regard to the other minerals.
In order to evaluate whether the trace elements are derived from natural or anthropogenic sources, four pollution indices were calculated. Additional keywords: carbonate mineral solubility, groundwater, sediment geochemistry.
