Evaluation of silver residues accumulation in tissues of Broilers treated with nanosilver using MNSR (A Clinical Trial)

Nanoparticles of silver were treaeted as clinical trials in some broiler farms for its disinfecting characters in 4 broiler farms during growing period. The nanosilver were used orally and inhalatory in amount of 2 -4 ppm and 40 ppm respectively. Some samples of Breast muscle, Femora muscle, Heart, Gizzard, Liver, Skin, Spleen, Lung, Kidney and Cloacal feces were collected randomly in slaughterhouse. The silver nanoparticles residues accumulation in samples were examined by miniature neutron source reactor (MNSR) with a high specificity and sensitivity in ppb levels. Regarding to the results the silver residues were detectable in all the samples (>131ppb),  The average of residues in ppb level in examined   samples were as 131(a) for Spleens, 132(a) for Gizzards, 144(a) for Hearts, 147(a) for Kidneys, 160(a) for Lungs, 168(a) (a)for Breast muscles, 172(a) for Femora  muscles, 185(a) for Livers, 194(a) for Skins and 557(b) for cloacal Feces.
