Using a Micro Sampler on a Drone to Extract Organic Vapors—A Case Study of Monitoring Industrial Pollution

Kaohsiung city located in the southern Taiwan is an industrial town and air pollutants were emitted from factories adjacent zones. In order to track pollution emission sources, a needle trap sampler (NTS), which micro solid phase microextraction (SPME) sampling device, was carried by quadrotor drone extract organic vapors industries. The NTS fabricated packing divinylbenzene (DVB) particles of 60–80 mesh diameters into 7 cm-long, 22-gauge stainless steel needle. telescoping device DJI Mavic Pro drone, its effectiveness for extracting processing exhausts chimneys studied. total weight including NTS, shaft, Li-battery, mini-air pump ABS (acrylonitrile butadiene styrene) loading frame, less than 200 g. mainly compounds, aromatic hydrocarbons (toluene 1,450±650 ppb, ethylbenzene 34±12 ppb xylenes 51±25 ppb), formaldehyde (50±12 alkanes (propane 30±10 triacetin (7,620±1600 ppb) terephthalic acid (20±5 collected then identified off-line gas chromatography (GC)-mass spectroscopy (MS) system laboratory. successfully monitored tracked their sources waste incineration, petroleum refinement, chemical electronic part production.
