The main components of kitchen oil fume are aldehydes, ketones, hydrocarbons, fatty acids, alcohols, aromatic compounds, ketones, lactones and heterocyclic compounds.

The toxicity of kitchen fume mainly includes:

Lung toxicity. Inhalation of cooking oil fume can cause lung inflammation and tissue cell damage in rats. Abnormal cell cycle and decreased apoptosis rate of lung tissue after inhalation of cooking oil fume in rats may be one of the mechanisms leading to lung cancer in rats.

Immunotoxicity, cooking oil fume can affect the cellular immunity, macrophage function, anti-tumor effect and immune monitoring function of the body, thus reducing the immune function of the body.

mutagenicity, there are genotoxic substances in cooking oil fume that can cause gene mutation, DNA damage, chromosome damage and other different biological effects.

Cooking oil fume is potentially carcinogenic to human body. Cooking oil fume has abnormal pathological changes in testis tissue of rats in different degrees, and it tends to get worse with the increase of exposure time. The condensate of kitchen oil fume also has a certain influence on the reproductive system of male Drosophila melanogaster, which can lead to infertility < P > To sum up, cooking oil fume contains many toxic chemical components, which are genotoxic, immunotoxic, lung toxic and potentially carcinogenic to the body. Cooking oil fume pollution and its harmful effect on human health are indoor environmental problems worthy of attention.
