In this
work, the presence of sea spray in the atmosphere of the semi-arid region of
Bahia, Brazil, was characterised by the investigation of rainwater and
atmospheric particulate matter, with the objective of studying the effect of
its transport on the salinization of the waters of the region. Stable isotopes
of deuterium and oxygen-18 were also calculated as environmental tracers in the
rain, determining the 18O/16O and D / H isotopic ratios. One of the major
processes of the cycling and redistribution of the different chemical elements
on the surface of the earth is atmospheric deposition. The atmosphere of the area,
as well as resuspended soil particles and anthropogenic sources, suffers from
considerable marine impact. The results show that the amount of sea spray
reaching the region is insufficient to interfere with the composition of the
groundwater and that local geology and the process of evaporation and salt
accumulation can be attributed to the cause of its salinization because of the
high temperatures found in the region.
