The TRIX and AZCI data grouped by transect for each season were analyzed by comparison of means with one-way ANOVA analysis of variance and box and whisker plot results were obtained.
AZCI results indicated better environmental quality in the summer and worse conditions in the autumn and winter.
The evidence of the results in this study suggests that these nutrient inputs are associated with increasing trophic state in the coastal ecosystem and where AZCI and TRIX indexes were consistent in indicating symptoms of eutrophication.
The effects of urban wastewater discharges to La Salada Cove were observed in two key variables, in addition to being indicated by the TRIX and AZCI. The responses of the body of water to sewage inputs were more evident by the fact that the summer condition in this study served as the reference.
