Description

technical field [0001] The invention relates to the technical field of detection, in particular to a device and method for pre-processing benzopyrene detection. Background technique [0002] Benzopyrene (BaP) is a class of organic compounds with obvious carcinogenic effects. It is a polycyclic aromatic hydrocarbon compound composed of a benzene ring and a pyrene molecule. It mainly exists in coal tar, various types of carbon black and coal, In the flue gas, cigarette smoke, and automobile exhaust produced by the combustion of petroleum, as well as in industrial sewage such as coking, oil refining, asphalt, and plastics; in addition to industrial sewage, BaP in surface water also comes from rainwater that washes the atmosphere, water storage tanks, and pipeline coatings Leaching; benzopyrene compounds in food mainly come from food contamination with benzopyrene during smoking or high-temperature cooking; pollution during food processing, asphalt pollution, packaging material ...
