Anthropic influence in the water quality of the river basin that supplies the Pato Branco Municipality-PR
The Pato Branco river basin, which supplies water to Pato Branco city (70,000 inhabitants) in southwestern Paraná State, was monitored during two hydrological cycles, totaling 22 campaigns at two monitoring stations on the Conrado river: the Conrado station upstream (RC01) and the Conrado station do...

| description | The Pato Branco river basin, which supplies water to Pato Branco city (70,000 inhabitants) in southwestern Paraná State, was monitored during two hydrological cycles, totaling 22 campaigns at two monitoring stations on the Conrado river: the Conrado station upstream (RC01) and the Conrado station downstream (RC02). The main characteristics of the basin here: area - 29.69 km², length - 9,300 m, height difference - 170 m, declivity - 18.62 m km-1, and concentration time - 102 min. Physico-chemical variables were analyzed, using samples collected after a minimum three-day period without rain. The data set comprising seven variables yielded the following averages respectively for monitoring stations RC01 and RC02: variables that characterized the organic matter: BOD5 (5.2 - 4.31mg L-1 O2) and COD (11.04 - 11.2 L-1 O2), and variables that characterized the eutrophication processes: ammoniacal N (0.16 - 0.09 mg L-1 N); nitrate (0.67 - 0.78 mg L-1 N); nitrite (0.06 - 0.029 mg L-1 N); total N (0.48 - 0.33 mg L-1 N), and total phosphorous (0.13 - 0.07 mg L-1). The lowest and the highest variation coefficients for data downstream and upstream corresponded to: nitrate and nitrite (46.1 and 166%); phosphorous and nitrite (56.8 and 229.6%).<br>A bacia hidrográfica do rio Pato Branco manancial de abastecimento público da cidade de Pato Branco localizada no Sudoeste do Estado do Paraná com uma população de 70.000 habitantes, foi monitorada pelo período de dois ciclos hidrológicos, totalizando 22 campanhas em duas estações de monitoramento: a estação Conrado montante (RC01) e a Conrado jusante (RC02) localizadas no rio Conrado. As principais características da bacia estudada foram: área de 29,69 km², comprimento 9.300 metros, desnível 170 metros, declividade 18,62 m km-1 e tempo de concentração 102 minutos. Analisou-se variáveis físico-químicas, cujas amostras foram coletadas respeitando um período mínimo de três dias sem chuvas. O conjunto de dados referente as sete variáveis para as estações de monitoramento RC01 e RC02 apresentaram respectivamente, as seguintes médias: variáveis que caracterizam a matéria orgânica: DBO5 (5,2 - 4,31 mg L-1 O2) e DQO (11,04 - 11,2 mg L-1 O2) e as que caracterizam os processos de eutrofização: N amoniacal (0,16 - 0,09 mg L-1 N); nitrato (0,67 - 0,78 mg L-1 N); nitrito (0,06 - 0,029 mg L-1 N); N total (0,48 - 0,33 mg L-1 N) e fósforo total (0,13 - 0,07 mg L-1). Os menores e maiores coeficientes de variação dos dados a montante e a jusante, foram observados nas variáveis: nitrato e nitrito (46,1 e 166%); fósforo e nitrito (56,8 e 229,6%). |
