This study investigated on the risk assessment of nano zeolite on development of embryonic chicken models, anomalies, tetratogenic and embryotoxic effects. Methods: Eggs (120 = n) were accidentally divided into 4 groups. In the experimental groups, 0.3 ml of the solution of nanozeolite (5,50,100 mg/L) injected into egg albumin, The eggs were then incubated for 19 days at 60% humidity and 37.5 ° C. At the end of incubation time, the fetus and organs (liver, heart, brain, spleen) weight and congenital anomalies were investigated. Results: The administration of nano-zeolite in chick embryos as a model for evaluating human embryonic damage showed teratogenic effects including deformity of legs and wings, liver and heart disformation at the doses of 50,100 mg/L. The embryo were smaller and significant morphological anomalous changes were observed. The comparison between the three experimental groups showed that the dose of 5 mg/L improved viability of chicken and showed increasing the dose of zeolite increases teratogenic effects and increased fetal mortality rate. Conclusions: The teratogenic effects of nanozeolits on chick embryo should be considered in the risk assessment of nanoparticles on human embryo and fetous.   UR - https://www.nanomedicine-rj.com/article_32927.html L1 - https://www.nanomedicine-rj.com/article_32927_b7e280a45ccaa6f9411a812ff7619e0b.pdf ER -
