The Vapor Density comparisons are only legitimate when the gas escaping is at the same temperature as the encompassing air by itself. In the event the chemical is escaping from a container where it was pressurized or refrigerated, it may well to start with escape and behave as being a large gas and sink inside the air (although it has a Vapor Density value under one). Also, the precise Gravity comparisons are for clean water (density 1.0 g/mL). If your spill is in salt water (density about one.027 g/mL), you might want to alter the point of comparison. There are many chemicals that will sink in fresh water and float in salt water.
