Nanoparticles NPs have emerged as a new class of environmental pollutants with the emergence of nanotechnology. Al2O3 NPs released from different industries, personal care products and wide range of applications necessarily end up in aquatic environments. Algal growth inhibition tests are an significant indicator model of monitoring programs designed to predict the effect of NPs on aquatic environments. This study investigated the effects of varyingduration and concentration exposure on the chlorophyll Chl contents of Al2O3 NPs to two species of freshwater green algae Desmodesmus sp., and Chodatodesmus mucranulatus recommended for use in standard algal growth inhibition tests. To induce Al2O3 NPs effect, we exposed algae to 3- 96 mg/L for 96 hours. In the test groups treated with Al2O3 NPs in both algae cells, chlorophyll content decreased in 48 hours exposure compared to the control groups and a clear increase in exposure time to 72 hours was observed. As a result, it was noted that the chlorophyll content of this study varied at the varying duration and concentrations. Variation in chlorophyll Chla and Chlb concentrations for Desmodesmus sp. and Chodatodesmus mucranulatus.was recorded at the significance level of p
Nanopartiküller NP’ler , nanoteknoloji ile birlikte çevre kirleticilerinin yeni bir sınıfı olarak ortaya çıkmıştır. Al2O3 NP’leri kişisel bakım ürünleri, farklı endüstriler ve geniş uygulama yelpazesinden salınır ve mutlaka sucul çevrelere ulaşır. Algal büyüme inhibisyon testleri, bu sucul çevrelerde NP’lerin etkisini öngörmek için tasarlanmış izleme programlarının önemli bir göstergesidir. Bu çalışmada, Al2O3 NP’lerinin değişen süresi ve konsantrasyonlarda, iki tatlısu yeşil alg Desmodesmus sp. ve Chodatodesmus mucranulatus türlerinde, standart alg büyüme inhibisyon testi ile klorofil klf muhteviyatını üzerine etkisi araştırılmıştır. Al2O3 NP etkisini değerlendirmek için algler 72 saat boyunca 3-96 mg/L konsantrasyonlarında Al2O3 NP’lerine maruz bırakıldı. Al2O3 NP’leri uygulanan test gruplarında, kontrol grupları ile karşılaştırıldığında klorofil muhtevasında net bir azalma gözlemlendi. Her iki alg hücresinde Al2O3 NP’leri ile muamele edilen test gruplarında klorofil muhteviyatı kontrol gruplarına kıyasla 48 saat sonra azaldı, maruz kalma süresi 72 saate uzadığında ise belirgin bir klorofil muhteviyatında artış gözlendi. Sonuç olarak, bu çalışmanın klorofil muhteviyatı Al2O3NP’lerinin değişen süre ve konsantrasyonlarda değiştiği kaydedilmiştir. Desmodesmus sp. ve Chodatodesmus mucranulatus için klorofil klfa ve klfb konsantrasyonlarında değişimi p
