In view of the need for sustainable development of the region, the state of the gulf's quality was assessed on the basis of determinations of nutrients (NO3 -, NO2 -, PO4 3-, SiO4 4-, and NH4 +) and trace metals (Cd, Cu, Fe, Pb, Ni and Zn) along with physicochemical parameters in the seawater. The samples were collected in three sampling cruises during February 2000, May 2000 and July 2000 from ten sampling stations. Nutrients were determined by standard colorimetric methods UV-Vis, using a Varian spectrophotometer. Dissolved metals were pre-concentrated using Chelex-100 resin. Particulate metals were digested following a hot plate digestion in teflon bombs. Metal concentrations were determined by Flame or Graphite Furnace Atomic Absorption techniques with a Varian spectrometer equipped with Zeeman background correction according to the concentration levels. Seasonal fluctuations were recorded in both nutrient and metal concentrations presenting proportional fluctuations with those of the marine euphotic zones. The reduction of concentrations can be attributed to the low rainfall seasonal height, the reduced flow of the streams and in the bioaccumulation and consumption from the phytoplankton cells that bloomed during spring and early summer.</p></abstract><publication_date><month>04</month><day>29</day><year>2013</year></publication_date><pages><first_page>127</first_page><last_page>133</last_page></pages><publisher_item><identifier id_type="pii">265</identifier></publisher_item><doi_data><doi>10.30955/gnj.000265</doi><timestamp>1713897417</timestamp><resource>https://journal.gnest.org/publication/265</resource></doi_data></journal_article></journal></body></doi_batch> </div>
