Abstract
Guayas province is the largest urban population of Ecuador with 3 645 483 inhabitants and during the last decade urban growth has been concentrated in the canton Duran In that sense, the anthropic activities have been derived in urbanism, agricultural development, and Industrial environment, which has altered the normal conditions of adjacent aquatic ecosystems. In the present study, the presence of nitrates, nitrites, and ammonium in the sediments of Estero San Camilo (adjacent to Durán) was determined in November 2015 during the dry season. Sediment sampling was carried out in four stations considering the main productive activity of the area (industrial, urban and agricultural), in which three replicates were collected using a Van Veen dredger. There were significant spatial variations (p<0.05) between the average concentrations of nitrogen compounds (ammonium 27.7 ± 2.3 mg / kg, nitrite 0.64 ± 0.06 mg / kg and nitrate 54 ± 2.7 mg / kg). Nitrates and nitrites recorded the highest average concentrations in stations with the urban influence. While the ammonium presented the highest values in the season with greater influence of agricultural zones. This shows the urban activity as the major polluting effect.References
