Disclosed are an underwater moving apparatus and a moving method thereof. The source may be a primary storage device. Additionally, the use of masks is consistent with the method, so intricate configurations can be achieved. Additionally, methods of removing atmospheric pollution compounds from a waste gas stream are disclosed that include introducing a waste gas stream and at least one additional gas stream, mist stream, liquid stream or combination thereof into a single-stage air scrubbing apparatus at a flow rate sufficient to allow for conversion of the at least one atmospheric pollution compound. The method is preferably implemented by a programmed computer.
