Abstract

QUEVEDO, Olga  and  CALDERON, Fernanda. Spatial distribution of sulfur in the atmosphere of the interior estuary of the Gulf of Guayaquil from passive samplers (Fenn and Poth, 2004) Guayaquil, Ecuador. RevActaNova. [online]. 2018, vol.8, n.3, pp.467-493. ISSN 1683-0789.

Sulfur levels were determined as a precursor of SO₂, deposited in the Port of Guayaquil, by comparing areas where 19 passive samplers were placed, during the dry season 2016 and rainy 2017, to calculate the rates of atmospheric deposition in mangrove ecosystems through the use of ion exchange resins and describe a map with QGIS, as well as the category of land use, obtaining the average critical load of 3,35 kg S ha^-1 year^-1, a value that shows a homogeneous distribution of sulfur, plus deficit extreme values between 5,014 and 9,50 kg S ha^-1 year^-1 in the dry season and 3,30 and 6,13 kg S ha^-1 year^-1 in the rainy season, in sensitive areas such as the mangrove ecosystems within the interior estuary of the Gulf of Guayaquil.

Keywords : sulfur; critical load; concentrations; port of Guayaquil.
