Aquatic ecosystems have been degraded over the years through anthropic activities with disorganized population growth has generated much problem for large cities resulting in damage to aquatic organisms and humans. The lack of basic sanitation causes an increase in the concentration of organic matter, nutrients and compounds of emerging interest through untreated or poorly treated household waste. The present study collected samples of 4 distinct points in the Barigui River. Physical and chemical analyzes of this water were carried out to verify which parameters of water quality were in accordance with the standard established by the standard and also to determine the influence or dependence that the other parameters exert on caffeine with the most significant parameters that were analyzed. The results found in the Barigui river basin adjacent to the metropolitan area of the city of Curitiba show the impact of the antropic activity in this river. The results show the presence of compounds requiring Oxygen, characterized by parameters such as COD and NH3, which showed a high correlation with caffeine (r greater than 0.9), evidence of its common source in the same way, a strong association was found of the metals analyzed with caffeine (greater than 0.8), which represents the influence that also has industrial dumping in the Barigui river.
