Doi cercet\u0103tori rom\u00e2ni anun\u0163\u0103 publicarea, \u00een prestigiosul jurnal Environmental Pollution, editat de Elsevier, a unui studiu care ofer\u0103 cele mai vechi dovezi ale polu\u0103rii antropice asupra faunei s\u0103lbatice din Europa Medieval\u0103, transmite Agerpres.<\/p>\n

Cercetarea a fost realizat\u0103 de o echip\u0103 franco-rom\u00e2n\u0103 condus\u0103 de dr. Marius Robu (Institutul de Speologie \u201eEmil Racovi\u0163\u0103\u201d al Academiei Rom\u00e2ne) \u015fi dr. Jeremy E. Martin (Ecole normale superieure, ENS, Lyon), al\u0103turi de dr. Ionu\u0163-Cornel Mirea, dr. Daniel Vere\u015f (Institutul de Speologie \u201eEmil Racovi\u0163\u0103\u201d al Academiei Rom\u00e2ne, Filiala Cluj-Napoca), dr. Sebastian Olive \u015fi Philippe Telouk.<\/p>\n

Cercet\u0103rile au fost realizate prin investigarea elementelor-urm\u0103 (Pb, Li, Zn) \u00een denti\u0163ia unui urs brun care a tr\u0103it \u00een urm\u0103 cu cca 1000 de ani \u00een Carpa\u0163ii Rom\u00e2ne\u015fti (Mehedin\u0163i \u2013 Banat), o zon\u0103 cunoscut\u0103 istoric pentru activit\u0103\u0163i metalurgice intensive desf\u0103\u015furate \u00eenc\u0103 din perioada medieval\u0103. Valorile de fond, precum \u015fi nivelurile ne-naturale (ridicate) de plumb (Pb), litiu (Li) \u015fi zinc (Zn) ale unui mascul de urs brun de aproximativ 5-6 ani au fost detectate folosind h\u0103r\u0163i de elemente-urm\u0103.<\/p>\n

Fragmentele elementelor analizate la \u00eenalt\u0103 rezolu\u0163ie \u015fi sec\u0163iunile histologice au eviden\u0163iat amploarea senzorial\u0103 a aportului de plumb, care a avut loc \u00een timpul a cinci veri \u00eenregistrate (c\u00e2nd animalul c\u0103uta \u00een mod activ hran\u0103). Concentra\u0163iile crescute de Pb, Li \u015fi Zn \u00een liniile terminale de cre\u015ftere au fost interpretate drept dovad\u0103 pentru cea mai timpurie poluare antropogen\u0103 cu metale grele la un animal s\u0103lbatic.<\/p>\n

Cercetarea subliniaz\u0103 impactul activit\u0103\u0163ilor industriale timpurii asupra unui omnivor terestru mare, demonstr\u00e2nd c\u0103 amenin\u0163\u0103rile antropice asupra vie\u0163ii s\u0103lbatice nu au fost determinate exclusiv de v\u00e2n\u0103toare sau modificarea peisajului din ultimele decenii.<\/p>\n

Rezultatele ob\u0163inute indic\u0103 cea mai veche dovad\u0103 documentat\u0103 despre impactul polu\u0103rii industriale asupra faunei s\u0103lbatice. \u00cen plus, amploarea polu\u0103rii cu metale grele \u00een acest\u0103 regiune dovede\u015fte existen\u0163a unor centre siderurgice cu o vechime \u015fi importan\u0163\u0103 deosebite la nivel european.<\/p>\n

Studiul este primul de acest fel care analizeaz\u0103 impactul polu\u0103rii antropice timpurii asupra faunei de mamifere s\u0103lbatice din Europa. \u00cen acela\u015fi timp, este un exemplu de colaborare interna\u0163ional\u0103 de succes, concretizat\u0103 prin accesul la tehnica de laborator disponibil\u0103 a Institut national des sciences de l\u2019Univers (CNRS-INSU, Fran\u0163a), dar \u015fi la un laser de \u00eenalt\u0103 precizie al Elemental Scientific Lasers, ENS, Lyon.<\/p>\n
