Divendres 1 de mar\u00e7 alumnes de Biologia de 2n de batxillerat de l\u2019Institut Francesc Maci\u00e0<\/strong> de Cornell\u00e0 de Llobregat han fet un estudi limnol\u00f2gic de la riera de Vallvidrera<\/a> a l\u2019al\u00e7ada de la font de Can Campreci\u00f3s<\/a>. Han seguit els protocols d\u2019inspecci\u00f3 de les campanyes del Projecte Rius.<\/a><\/p>\n

\"\"<\/a>Han comen\u00e7at considerant quins par\u00e0metres podien investigar per con\u00e8ixer la qualitat ecol\u00f2gica de la riera. L\u2019estudi es completa a partir de 3 fonts d\u2019informaci\u00f3: dades fisicoqu\u00edmiques de l\u2019aigua, qualitat del bosc de ribera i qualitat de l\u2019aigua a partir de bioindicadors. S\u2019han dividit en grups de treball i han revisat tot el material necessari.<\/p>\n

\"\"<\/a>Un cop a la riera han recopilat diverses dades ambientals com coordenades UTM, temperatures, tipus de substrat, velocitat, amplada, fond\u00e0ries, transpar\u00e8ncia, etc. \u00a0Posteriorment han pogut calcular el cabal amb l\u2019ajut del programa Cabalsec<\/a>. Han agafat mostres d\u2019aigua per analitzar al laboratori i obtenir par\u00e0metres com duresa, conductivitat, mineralitzaci\u00f3, concentraci\u00f3 de nitrits i fosfats. Amb els kits de valoraci\u00f3 del Projecte Rius han determinat el pH aix\u00ed com la concentraci\u00f3 de nitrats i oxigen dissolt. Amb l\u2019ajut dels protocols QRISI han pogut valorar l\u2019index de qualitat del bosc de ribera.<\/p>\n

Finalment han capturat macroinvertebrats de la riera i al laboratori amb l\u2019ajut de lupes binoculars i fitxes de suport els han identificat i han obtingut els corresponents indexs biol\u00f2gics. A partir d\u2019aquestes dades han pogut determinar la qualitat de l\u2019aigua en base al protocol IBMWPC. Posteriorment han tornat a alliberat tots els animals a la riera.<\/p>\n

Han demostrat que tenen molt bones maneres per fer ci\u00e8ncia i els agra\u00efm la seva implicaci\u00f3 en la recollida de deixalles de la riera que fem en col\u00b7laboraci\u00f3 amb\u00a0 el col\u00b7lectiu Petjada Verda<\/a>.<\/p>\n","protected":false},"excerpt":{"rendered":"
