En aquest sentit, els tipus de micropl\u00e0stics que s\u2019analitzaran en aquest contracte seran el polietil\u00e8 (present en bosses de pl\u00e0stic, ampolles), el polipropil\u00e8 (envasos, canyes, fibres industrials) i poliestir\u00e8 (escumes, estris de cuina i joguines), entre d\u2019altres.<\/p>\n\n\n\n
S\u2019han escollit un total de 54 punts de mostreig a les principals conques fluvials catalanes, concretament en el riu Llobregat, la conca del Ter, la Muga, la Tordera, el Fluvi\u00e0, el Bes\u00f2s, el Foix, l\u2019Anoia, el Segre i les rieres de Rub\u00ed i la Bisbal.<\/p>\n\n\n\n
S\u2019analitzaran diversos trams de riu, l\u2019aigua que entra i surt d\u2019algunes depuradores, aix\u00ed com trams fluvials amb poques pressions (cap\u00e7aleres). En total, s\u2019agafaran 123 mostres, que es recolliran a trav\u00e9s de tres campanyes de mostreig.<\/p>\n\n\n\n
Aquest contracte, un cop estigui adjudicat i formalitzat, tindr\u00e0 una durada total de 23 mesos: 14 per a fer els mostrejos, 3 per a l\u2019an\u00e0lisi de les mostres i tres m\u00e9s per a l\u2019obtenci\u00f3 de resultats.<\/p>\n\n\n\n
El contracte, de manera pionera, servir\u00e0 per a identificar la pres\u00e8ncia de micropl\u00e0stics en els nostres rius i poder definir, en el futur, actuacions per a minimitzar la pres\u00e8ncia d\u2019aquests contaminants.<\/p>\n","protected":false},"excerpt":{"rendered":"
