摘要:Kaohsiung city located in the southern Taiwan is an industrial town and air pollutants wereemitted from factories in the adjacent industrial zones. In order to track the pollution emissionsources, a needle trap sampler (NTS), which is a micro solid phase microextraction (SPME)sampling device, was carried by a quadrotor drone to extract organic vapors from industries. TheNTS was fabricated by packing divinylbenzene (DVB) particles of 60–80 mesh diameters into a7 cm-long, 22-gauge stainless steel needle. The telescoping sampling device was carried by a DJIMavic Pro quadrotor drone, and its effectiveness for extracting organic vapors from industrialprocessing air exhausts from chimneys was studied. The total weight of sampling device,including a NTS, a telescoping shaft, a Li-battery, a mini-air pump and the ABS (acrylonitrilebutadiene styrene) loading frame, was less than 200 g. The mainly emitted compounds, includingaromatic hydrocarbons (toluene of 1,450 ± 650 ppb, ethylbenzene of 34 ± 12 ppb and xylenes of51 ± 25 ppb), formaldehyde (50 ± 12 ppb), alkanes (propane of 30 ± 10 ppb), triacetin (7,620 ±1600 ppb) and terephthalic acid (20 ± 5 ppb) were collected and then identified by the off-linegas chromatography (GC)-mass spectroscopy (MS) system in the laboratory. The quadrotor dronesuccessfully monitored air pollution and tracked their emission sources from waste incineration,petroleum refinement, chemical processing and electronic part production.
