Narrative:

On takeoff; the flight attendants chimed the cockpit 4 times and told us there were very strong fumes and a haze in the cabin. They said it was burning their eyes and throats and it was really bad. They also said the passenger were coughing and complaining. We could smell a burning smell in the cockpit; however; no smoke or fumes. We declared an emergency with regional departure and returned uneventfully. After landing; the crash fire rescue equipment inspected the aircraft with no significant findings and we returned to the gate. Callback conversation with reporter revealed the following information: reporter stated that on postflt inspection; maintenance discovered an APU oil leak allowing oil into the air conditioning packs. As a result; an acrid oily smelling blue haze developed in the cabin.
