Abstract
Apex bird species are proven to be relevant bioindicators for assessing environmental pollutants. To achieve this, the goal of this work was to compare biomarker responses in two fractions of white stork (Ciconia ciconia) nestling blood; establish novel biomarker approaches (esterase, fluorescent dyes, metallothioneins), apply previously analysed biomarkers (glutathione-dependent enzymes); investigate the differences in biomarker responses related to metal(loid)s in white stork nestling's blood from Croatia. Results indicate differences between the fractions in biomarker response based on variability. The pollutant impact from the surrounding metal, petroleum, and agricultural industry appears to affect the biomarkers responses/levels in white stork nestlings, which are often seen as early-warning signals. Observed increased metal(loid) levels at the landfill and agricultural areas might cause adverse effects on the nestlings. This first-time metal(loid) analyses in Croatian white stork nestlings indicate the necessity of biomonitoring and local assessments of pollution impact to prevent detrimental effects on the environment.
Abstract (croatian)
Bijela roda izvrsna je modelna vrsta za praćenje zagađenja u okolišu. U ovom doktorskom radu provedeno je istraživanje odgovora biomarkera i koncentracije metal(oid)a u krvi ptića bijele rode (Ciconia ciconia) s područja Hrvatske. Ciljevi rada su: usporediti odgovore biomarkera u dvije frakcije krvi, uspostaviti nove protokole za mjerenje biomarkera (aktivnost esteraze, fluorescentne boje za detekciju oksidativnog stresa i razine metalotioneina), primijeniti prethodno analizirane biomarkere (glutation-ovisne enzime) i istražiti razlike u odgovorima biomarkera vezanih za metal(oid)e. Rezultati ukazuju na razlike između frakcija u odgovoru biomarkera. Moguć je utjecaj zagađivala iz okolne metalne, naftne i poljoprivredne industrije na biomarkere u ptićima bijele rode, koji se često smatraju ranim znakovima upozorenja. Povećane razine metal(loid)a na odlagalištima i poljoprivrednim površinama mogu uzrokovati štetne učinke na ptiće. Ovo je prvo istraživanje metal(loid)a u ptićima bijele rode s područja Hrvatske te ukazuju na neophodan monitoring za procjenu utjecaja zagađenja kako bi se spriječili štetni učinci.
