The SF6 gas toxicity biological test method involves simulating the atmospheric composition by mixing 79% sulfur hexafluoride (SF6) gas with 21% oxygen (O2) by volume. This mixture is designed to mimic the normal air environment, allowing mice to be continuously exposed to the gas for a full 24-hour period. After this exposure, the animals are observed for an additional 72 hours in a normal air environment. Researchers monitor the mice for any signs of abnormal behavior, physiological changes, or mortality. The presence or absence of such abnormalities helps determine whether the SF6 gas sample is toxic to living organisms. This testing method provides critical insights into the potential health risks associated with SF6 exposure and is commonly used in safety evaluations for industrial and environmental applications.
