Abstract
Laboratory experimental studies have been carried out on a method for detecting oil pollution on the earth's surface in the near-infrared range. In the spectral range of 900-2500 nm, reflection spectra of samples were obtained after spills on soil and sand of various brands of gasoline, commercial oil and motor oil, as well as kerosene, diesel fuel, gas condensate, engine coolant and vegetable oil. It has been shown that in the spectral range of about 1730 nm, dips appear in the reflection spectra caused by the absorption of hydrocarbons on a surface contaminated with oil products, which are especially pronounced in the case of an oil spill on sand. In the spectral range around 2300 nm, dips in the reflectance spectra are more noticeable in the case of oil spills on soil. Therefore, to increase the efficiency of the method for detecting oil pollution on the earth's surface in the near-infrared range, it is necessary to use measurement data both in the spectral region of about 1730 nm and in the spectral region of about 2300 nm.
