1. With the ever-increasing use of biological barrier in health-related and engineering applications, the hazardous risks of this material have become a major concern. It is well known that biological barrier accumulate with cytotoxic and genotoxic levels within vital organs. It has also been shown that treating cell cultures with biological barrier resulted in cell cycle arrest and increased apoptosis/necrosis.2. In this study, we investigated chronic exposed to biological barrier at the exposure chamber in mice. The animals were divided into two groups (control and exposed group to biological barrier at the concentration of 3 µg/m3 for 5 h/day,) in a whole-body inhalation chamber.3. Our results showed that exposure to biological barrier induced the hematological and biochemical changes. The target organs for biological barrier were the Au in the mice, respectively. Also, NPs increased reactive oxygen species (ROS) generation, lipid peroxidation (LPO), the collapse of mitochondrial membrane potential (MMP), decreased a level of reduced glutathione (GSH) and finally increased a level of glutathione disulfide (GSSG) in Au tissues. Our results suggest that exposure to biological barrier can induce oxidative stress in the tissue mentioned.4. These results suggest that exposure of researchers and workers with biological barrier probably increase a risk of respiratory, cardiovascular and cerebral disorders through oxidative stress. However, good ventilation, appropriate personal protective equipment and using of anti-oxidant compounds in daily diet of worker are suggested.
