In cases of application of this method in forensic-ecological expertise provides the ability to increase the level of environmental safety. The mathematical apparatus, which forms the basis of this method, has been developed using elements of fuzzy set theory. Three new technical solution is sampling, providing the ability to perform multiple sampling samples of the medium light oil has been eveloped.the initiator of combustionlight oilidentificationenvironmental safetysampling environmentfuzzy setsинициатор горениясветлые нефтепродуктыидентификацияэкологическая безопасностьотбор проб средынечеткие множества
