Gaseous pollutant sampling mechanism, sampling system and method convenient for airplane aerial survey

The invention discloses a gaseous pollutant sampling mechanism, a sampling system and a sampling method convenient for airplane aerial survey. The invention solves the problems that a sampling mechanism in the prior art is complex in structure and inconvenient to carry, and has the advantages of small sampling loss and convenience in carrying as a whole. The scheme of the invention is as follows:the gaseous pollutant sampling mechanism convenient for airplane aerial survey comprises an L-shaped sampling pipe, wherein one side of the sampling pipe is equipped with a suction nozzle, the inlet side size of the suction nozzle is less than the exit side size of the suction nozzle, the suction nozzle and the sampling pipe structure work as an organic whole, the opposite side of sampling pipe can pass an airplane trompil setting, one side that the sampling pipe can pass the airplane is provided with a fixed plate that can be connected with airplane internal connection, and the side that thesampling pipe can pass the
