In this study the direct absorbance of Nano zinc oxide by a bivalvia (carbicula fluminea) tested in 48 h as short time period. The bivalvia stock with initial mean length 2.5 + 0.9 cm were gathered from nature resources and transferred into laboratory and distributed in 10 aquariums. Nano particles were spread in oltrasonic with 400 rpm. The tanks water was emulsioned with nanoparticles by homogenizer in 14000 rpm. The treatments were exposed to 0.25, 2.5 & 25 ppm nanoparticles. The Nano zinc oxide stocks in bivalves tissue and their distribution were measured by ICP & DLS. The results showed that the most nanoparticles were observed in the treatment which exposed to 0.25 ppm pollution ( p <0.05) and the less absorbance was seen in the treatment which exposed to 25 ppm (p<0.05). The DLS test showed that the nanoparticles size was between 10-100 nanometers which confirmed that the nanoparticles were homogenized and didn’t sequestrate. In conclusion, the observance by bivalvia can be a benefit index for measuring the Nano zinc oxide's pollution in water.
