Due to the fact that our country has the world's leading boron deposits, aquatic ecosystems are exposed to intense forms of boron. In this research, bioaccumulation of boron particles (micro and nano) which are formed with removal and operation of boron in Turkey and of boron nanoparticles which are used in the nanotechnology industry have been evaluated on single cell fresh water algae (Desmodesmus multivariabilis). As a result of this study, it has been observed that nano and micro boron particles accumulate in different amounts in the algae. When we look at the highest accumulation amounts, the accumulation was in 0.01 mg/l concentrations for both particles and it was measured as 6.390 ppb for nano boron, 12.490 ppb for micro boron. The difference between the concentration groups of boron particles in Desmodesmus multivariabilis was found to be significant (P <0.01).Original Abstract: Ulkemizin dunyanin onde gelen bor madeni yataklarina sahip olmasindan dolayi, sucul ekosistemler bora yogun sekilde maruz kalmaktadir. Bu arastirmada, Turkiye de bor madeninin isletilmesi, cikarilmasi ile olusan bor partikulleri (nano ve mikro bouytlu) ile nanoteknoloji endustrisinde kullanilan bor nanopartikulunun biyolojik birikimi tek hucreli tatli su alginde (Desmodesmus multivariabilis) degerlendirilmistir. Bu calisma sonucunda, alglerde nano ve mikro bor partikullerinin farkli miktarlarda birikim gosterdigi gozlenmistir. En yusek birikim miktarlarina baktigimizda her iki partikulu icin 0.01 mg/l konsantrasyonlarda kaydedilmistir. Olculen bor miktarlari, nano bor icin 6.390 ppb mikro bor icin 12.490 ppb dir. Desmodesmus multivariabilis de bor partikullerinin konsantrasyon gruplari arasindaki farkliliklar istatistiki olarak onemli bulunmustur(P<0.01).
