Asphalt is toxic, Toxicology Database

Acute toxicity: The skin was coated with 30% coal modified asphalt tar pitch toluene solution for 3 times, and some parts appeared hyperkeratosis and chapped after inflammation.

Poisoning mechanism: Phototoxicity: Asphalt and its contained anthracene, phenanthrene, acridine, etc. are all phototoxic substances, which can cause photobiological effects under the action of ultraviolet rays. The phototoxic reaction formed by asphalt is a photochemical reaction of asphalt through the action of light energy under aerobic conditions. The free radicals and peroxides generated by the reaction cause cell damage, so it is a non-immune reaction. Systemic effects: Coal tar pitch coating has a more significant effect on animal weight gain than petroleum pitch, and coal tar pitch skin coating is more harmful to animals than its smoke inhalation. It is suggested that coal tar pitch has a certain systemic effect on animals, and the degree of its effect is related to the absorption pathway.

Irritant: It is irritating. The main components modified asphalt of asphalt and its flue gas are phenolic compounds, anthracene, naphthalene, pyridine, etc., which are irritating to the skin and mucous membranes.

Carcinogenicity: In my country, mice are coated with skin, and the test also shows that asphalt can cause skin cancer, most of which are squamous cell carcinoma, and a few are keratinizing papilloma. It is generally believed that coal tar pitch is the most carcinogenic, and natural pitch is not carcinogenic; the carcinogenicity of petroleum pitch is not the same.

Environmental hazard: It is harmful to the environment and can cause pollution to the atmosphere.

Asphalt is a very important product in our life. It has very good water resistance, fire resistance, strong corrosion resistance, strong acid resistance and moisture resistance. Therefore, asphalt is widely used in many operations, such as travel manufacturing, coating operations, plastic operations, rubber operations, etc. Asphalt and smoke are very harmful to the human body, and are very irritating to the skin and mucous membranes. They have phototoxic and carcinogenic effects, so we should stay away from asphalt in normal times.If you have any other questions, please contact us modified asphalt for details or contact us directly.
