Aniline banned as food colouring after it was used to make fake kampung chicken Sept 28, 2013 NEWS
What is aniline? Another name for aniline is aminobenzene, an organic compound. It is light yellow in colour.
Aniline
It is a precursor to many industrial chemicals, its main use is in the manufacture of precursors to polyurethane (type of plastic, eg styrofoam)).
Like most volatile amines, it possesses the somewhat unpleasant odor of rotten fish
.
Aniline can be toxic if ingested, inhaled, or by skin contact. Aniline damages hemoglobin, a protein that normally transports oxygen in the blood. The damaged hemoglobin can not carry oxygen.
Methemoglobinemia is the most prominent symptom of aniline poisoning in humans, resulting in cyanosis (a purplish blue skin color) following acute high exposure to aniline. Dizziness, headaches, irregular heart beat, convulsions, coma, and death may also occur. Direct contact with aniline can also produce skin and eye irritation.
Long-term exposure to lower levels of aniline may cause symptoms similar to those experienced in acute high-level exposure. The International Agency for Research on Cancer (IARC) determined that aniline is not classifiable as to its carcinogenicity to humans.
Is there a medical test to show whether I’ve been exposed to aniline?
Aniline can be measured in the urine. This test shows that you have been exposed to aniline but not to how much or how recently. A breakdown product of aniline in the body, p-aminophenol, also can be measured in the urine; however, this breakdown product is not specific for aniline exposure.
Methemoglobin can be measured in the blood, but exposure to many other chemicals also increase methemoglobin levels in the blood. Methemoglobin levels in blood can be used to determine the appropriate treatment that exposed individuals should receive. These tests are not routinely done in a doctor's office.
