Simulated vehicle exhaust exposure (SVEE) model apparatus. SVEE consists of a whole body exposure system with two chambers fitted with tubing systems to allow inflow and outflow of gaseous mixtures. There is a cylinder that contains simulated mixture of vehicle exhaust. Gaseous mixture from the cylinder is blended with air in the mixer and then flow of the mixture is controlled using a flow regulator. Rats were subjected to SVEE in this apparatus.
