Caffeine as an indicator of human fecal contamination in the Sinos River: a preliminary study

Abstract: The preservation of hydric resources is directly related to fecal contamination monitoring, in order to allow the development of strategies for the management of polluting sources. In the present study, twenty-five water samples from six water public supply collection sites were used for the evaluation of the presence of caffeine, total and fecal coliforms. Caffeine was detected in all samples, with concentrations ranging from 0.15 ng mL -1 to 16.72 ng mL -1 . Total coliforms were detected in all samples, with… Show more

“…Um estudo em Portugal, também indicou valores maiores de cafeína em áreas urbanas (SILVA et al, 2014), confirmando assim a vantagem de ser um bom marcador de dejetos humanos e de não estar presente em lançamentos agrícolas ou industriais (PEELER et al, 2006;LINDEN et al, 2015), uma vez que este local possui maior concentração de áreas residenciais.…”
