Abstract
Nanočestice su sve više prisutne u svakodnevnom životu. Time se pospješuje mogućnost njihova doticaja sa našim okolišem kako zrakom, kopnom tako i vodama, morskim i slatkim. Jednom prisutne u okolišu mogu stupiti u razne interakcije s tamošnjim organizmima ponekad uzrokujući i negativne posljedice po doticajnu jedinku. Cilj ovog rada bio je ispitati učinak sintetiziranih nanočestica srebra na oplodnju i embrionalni razvoj ježinca Arbacia lixula nakon tretmana jajnih stanica prethodno pripremljenim česticama. Istraživanje je pokazalo kako povećanjem koncentracija nanočestica dolazi do redukcije same oplodnje ježinaca tj. smanjuje se uspješnost oplodnje ježinaca i to proporcionalno opada s porastom koncentracije nanočestica. Isto tako uspješnost dostizanja faze larve opada porastom koncentracije nanočestica. Veće koncentracije nanočestica povećale su brojnost nerazvijenih larvi te umanjile broj normalno razvijenih.
Abstract (english)
Nanoparticles are increasingly present in everyday life. This increases the likelihood of their contact with our environment such as air, land and water(sea and sweet waters). Once present in the environment, they can participate in various interactions with organisms, sometimes causing negative consequences for the touching individual. The aim of our work was to examine the effect of synthesized silver nanoparticles on fertilization and embryonic development in ovarian A. lixula after the treatment of egg cells of pre-prepared parts. Research has shown that increasing nanoparticle concentrations results in reductions in the insemination of sea urchin, i.e., the efficiency of fertilizer growth proportionally decreases with the increase in nanoparticle concentration. Likewise, the success of reaching the larvae stages decreases with the increase in the concentration of nanoparticles. Larger concentrations of nanoparticles increase the number of underdeveloped and reduce the number of normally developedlarvae.
