Dimarts 20 de novembre alumnes de Biologia de 1r de batxillerat de l\u2019Institut Joan Brossa<\/strong> de Barcelona han fet un estudi limnol\u00f2gic de la riera de Vallvidrera<\/a> en un punt proper a Can Santoi. Les dades del seu estudi formaran part de la campanya d\u2019inspecci\u00f3 de tardor 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 el completaran 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.
\nS\u2019han dividit en grups de treball i han realitzat el treball de camp al voltant de la font de l\u2019arbre caigut. S\u2019han trobat la riera for\u00e7a crescuda degut a les intenses pluges dels \u00faltims dies.<\/p>\n

\"\"<\/a>Han recopilat diverses dades ambientals com coordenades UTM, temperatures, tipus de substrat, velocitat, amplada, fond\u00e0ries, transpar\u00e8ncia, etc. Posteriorment 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.
\nFinalment han capturat macroinvertebrats de la riera i els han identificat al laboratori amb l\u2019ajut de lupes binoculars i fitxes de suport\u00a0 i han obtingut els corresponents \u00edndexs biol\u00f2gics. A partir d\u2019aquestes dades han pogut determinar la qualitat de l\u2019aigua en base al protocol IBMWPC. Posteriorment s\u2019han tornat a alliberat tots els animals a la riera.
\nHan demostrat que tenen molt bones maneres per fer ci\u00e8ncia i han sigut uns grans col\u2022laboradors del Projecte Rius<\/a><\/p>\n","protected":false},"excerpt":{"rendered":"
