| Resumo: |
The quality of water resources, which are of great importance for public supply, is being directly affected by population growth. In view of the anthropogenic influences, this study aims to assess the concentrations of caffeine and compare them with physical and chemical parameters and biological, thus
verifying the possibility to be more an indicator of anthropogenic activity. For
this study four samples were taken bimonthly from February to December 2010 at 12 points in the Upper Iguaçu, in the metropolitan region of Curitiba. Were analyzed in the field at the time of collection the pH, conductivity, water temperatures and air, dissolved oxygen, oxygen saturation and laboratory analysis was performed of nitrite, nitrate, ammonia nitrogen, total nitrogen, organic nitrogen, dissolved phosphorus, orthophosphate , total phosphorus, alkalinity, BOD, COD, UV-VIS, fluorescence, dissolved organic carbon and
caffeine. The results obtained showed that caffeine acts as an indicator of
wastewater, especially when the entry is new, and in areas with greater population density. |
