It's possible. Kitchen lampblack is the lampblack produced after cooking oil and food are heated at high temperature. High-temperature cooking is a unique cooking habit in China, so the kitchen fume formed during high-temperature cooking has become one of the main air pollutants in our indoor living environment. In recent years, with the improvement of people's living standards and the development of catering industry, the consumption of edible oil has been increasing, and the harm of lampblack to health has been paid more and more attention.

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 body's cellular immunity, macrophage function, anti-tumor effect and immune monitoring function, thus reducing the body's immune function.

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 different degrees of abnormal pathological changes in rat testis, and it tends to get worse with the increase of exposure time. The condensate of kitchen oil fume also has a certain effect on the reproductive system of male Drosophila melanogaster, which can lead to infertility.

To sum up, cooking oil fume contains a variety of toxic chemical components, which are genotoxic, immunotoxic, lung toxic and potentially carcinogenic to the body. Cooking oil fume pollution and its harm to human health are indoor environmental problems worthy of attention.
