Özet:

 


Nanoparticles have great impact due to their tremendous industrial
applications. However, their applications have produced toxicity effects on the
aquatic environments and their detailed analyses are not clearly understood.
Iron oxide nanoparticles (Fe2O3 NPs) are being used
extensively in many industries but are considered highly toxic to aquatic
species residing in surface waters. This paper demonstrates the acute
toxicity of a-Fe2O3 and g-Fe2O3NPs in two aquatic
species. The effects of various concentration (0, 50, 100, 250, 500 and 1000
mg/L) of a-Fe2O3 and g-Fe2O3 on the sensitivity
response of the Chlorella sp. and D. magna were investigated. The growth
of microalgal decreased with increased concentration of the a-Fe2O3 and g-Fe2O3 NPs concentrations but
did not show a significant toxic effect. The EC50 concentration
value was 500 mg/L and LD50 concentration value was 1000 mg/L for a-Fe2O3 treated daphnids in 72 h,
respectively. The findings demonstrate the significant evidence in
understanding acute toxicity of Fe2O3 NPs for environmental
protection as part of risk assessment strategies.
