The study aimed to determine the level of LAS in the Huatanay river; in Cusco city, Peru. Water samples were taken from nine points along the river, in the rainy and dry season in 2018. LAS surfactants were determined spectrometrically using methylene blue as indicator; dissolved oxygen (DO) and conductivity were also determined; both were correlated through Pearson coefficient at 5% significance, and analyzed in triplicate. The concentration of LAS in the dry season varied between 0.01 to 23.17 mg/L and in rains from 0.09 to 1.47 mg/L; the DO level shows values between 0.11 to 5.04 mg O2/L, and the conductivity varied from 777.7 to 2688.9 µS/cm. In conclusion, high levels of LAS considerably decrease the DO and increase the conductivity 2021 artículo científico 0012-7353 https://www.redalyc.org/articulo.oa?id=49671281001 https://www.redalyc.org/journal/496/49671281001/ https://www.redalyc.org/journal/496/49671281001/html/ https://www.redalyc.org/journal/496/49671281001/49671281001.epub https://www.redalyc.org/journal/496/49671281001/movil 10.15446/dyna.v88n217.90795 en http://www.redalyc.org/revista.oa?id=496 Dyna application/pdf Universidad Nacional de Colombia Dyna (Colombia) Num.217 Vol.88 |
