$\"\"$ <\/a>Un 45% dels residus que es troben a les zones de ribera m\u00e9s properes als rius Bes\u00f2s, Ter, Tordera i Fluvi\u00e0 s\u00f3n pl\u00e0stics, i d\u2019aquests el 80% s\u00f3n d\u2019un sol \u00fas, principalment bosses, embolcalls de menjar i tovalloletes higi\u00e8niques. La majoria de residus \u00e9s probable que provinguin de les poblacions properes i dels visitants al riu. Aquestes s\u00f3n algunes de les conclusions que es desprenen dels mostrejos que han fet aquesta primavera uns 800 alumnes d\u2019una vintena de centres educatius catalans, majorit\u00e0riament d\u2019educaci\u00f3 secund\u00e0ria, en el marc del projecte Pescadors de Pl\u00e0stics, una iniciativa del Centre Tecnol\u00f2gic BETA de la Universitat de Vic – Universitat Central de Catalunya (UVic-UCC).<\/p>\n

Durant aquesta primavera els estudiants han mostrejat 49 trams de riu diferents, a les conques del riu Bes\u00f2s (24 trams), baix Ter (17 trams), la Tordera (6 trams) i Fluvi\u00e0 (2 trams). Al llarg de tots els trams mostrejats, els joves han pogut identificar un total de 110 residus flotants a l\u2019aigua del riu, la meitat dels quals eren residus pl\u00e0stics, principalment bosses i ampolles de pl\u00e0stic.<\/p>\n

Per analitzar la pres\u00e8ncia de residus a la ribera del riu, durant el mostreig es van diferenciar dues franges: una m\u00e9s propera a l\u2019aigua i una altra m\u00e9s allunyada. A la zona m\u00e9s pr\u00f2xima al riu, es van identificar entre tots els trams mostrejats un total de 776 residus. Tenint en compte l\u2019\u00e0rea mostrejada, suposen 0,26 residus\/m2 i del total, un 45% eren pl\u00e0stics. A la zona m\u00e9s allunyada del riu es van identificar fins a 986 residus, que equivalen a 0,36 residus\/m2, i es va observar que d\u2019aquests un 46% eren pl\u00e0stics.<\/p>\n

Per categories d\u2019aquests residus, la m\u00e9s abundant (44%) eren pl\u00e0stics d\u2019un sol \u00fas, seguits del vidre (12%), metalls (11%, principalment llaunes de begudes), paper (9%) i burilles de cigars (7%). Pel que fa als pl\u00e0stics d\u2019un sol \u00fas, l\u2019estudi destaca que sobretot es van identificar bosses de pl\u00e0stic, embolcalls de menjar i tovalloletes higi\u00e8niques, les quals estan compostes principalment per fibres sint\u00e8tiques de pl\u00e0stic.<\/p>\n","protected":false},"excerpt":{"rendered":"
