Narrative:

On final approach to bwi, the captain and I noticed an unusual odor in the cockpit, not strong, but similar to antifreeze. Baltimore approach told us to expect runway 33. We requested runway 28 and told approach we had the airport in sight. Approach cleared us for visual approach to runway 28. I was looking down in my briefcase, pulling runway 28 ILS out for backup. Looked up and noticed the captain turning the aircraft away from runway 28 toward the north. I queried him as to where we were going. He said runway 28 and I said something was not right. Then he lined the aircraft on a 220 degree heading. About that time, tower called and told us we were lined up on runway 22 and asked if we could sidestep to runway 28. We said yes and landed on runway 28 without incident. Also leaving cle for flight to bwi we climbed to FL290. When ordered to start our descent from FL290, I noticed altimeter (captain and first officer's) set on 30.49 and brought this to captain's attention. We reset to 29.92. I and captain have never done this before. Once on ground at bwi, we asked the agent who came up to the cockpit if he smelled anything. He said yes. We also asked the 2 mechanics who came up to the cockpit, and they smelled something sweet. No leakage was noticed from rain repellent bottle behind first officer's seat. Captain had airport medics meet us and requested oxygen. He said he felt a little dizzy.
