Possible routes of exposure include inhalation, skin contact, eye contact, and ingestion. Acrylamide is highly toxic by inhalation and skin contact. It can easily penetrate intact skin. Acrylamide is known to affect the nervous system with early signs of exposure including numbness, tingling, and tenderness to touch.
Symptoms can be delayed several days to weeks and if exposure continues (even in small quantities), other symptoms may arise including excessive sweating, blue-reddish skin, peeling of skin, and weakness in limbs. It is a mutagen and teratogen and is classified by IARC as Probably Carcinogenic to Humans (Group 2A).
The Cosmetic Ingredient Review (CIR) Expert Panel acknowledged that acrylamide is a demonstrated neurotoxin in humans and a carcinogen in animal tests, but that neurotoxic levels could not be attained by use of cosmetics.
Leaves through bodily fluids: Once in your body, acrylamide enters your body fluids. Acrylamide and its breakdown products leave your body mostly through urine; small amounts may leave through feces, exhaled air, and breast milk.
Nervous system effects such as muscle weakness, numbness in hands and feet, sweating, unsteadiness, and clumsiness were reported in some acrylamide workers. However, most people are not exposed to acrylamide levels high enough to cause these effects.

Acrylamide has been shown to cause cancer in animals exposed to very high doses, and although there is no consistent epidemiological evidence on the effect of acrylamide from food consumption on cancer in humans, both the U.S. National Toxicology Program and the Joint Food and Agriculture Organization/World Health ...
The highest levels appear in fried and roasted potato products and in cereal products such as breads, crackers, and breakfast cereals (Table 1). Because of the high temperatures used for roasting of the beans, coffee and cocoa also have moderately high levels of acrylamide (6).
Any type of coffee product that derives from roasted coffee beans will contain acrylamide, including instant coffee. Coffee substitutes, such as cereal and chicory root coffees, that have undergone roasting also contain acrylamide. However, the amount of acrylamide in these different types of coffee can vary.
The long-term effect of acrylamide may cause irreversible changes in the nervous system and disturbance of the transmission of impulses between neurons [7]. In addition, studies show that acrylamide in low doses causes oxidative stress in various organs [8].
OSHA: The legal airborne permissible exposure limit (PEL) is 0.3 mg/m3 averaged over an 8-hour workshift. NIOSH: The recommended airborne exposure limit (REL) is 0.03 mg/m3 averaged over a 10-hour workshift.
It is a white odorless solid, soluble in water and several organic solvents.
Synonyms: 2-propenamide, acrylic amide, ethylenecarboxamide, propenoic acid, amide propenamide, acrylamide monomer RCRA waste number U007, UN 2074, vinyl amide.
Studies in rodent models have found that acrylamide exposure increases the risk for several types of cancer (10–13). In the body, acrylamide is converted to a compound called glycidamide , which causes mutations in and damage to DNA.
Treat site with 1.6% potassium persulfate, then with 1.6 % sodium metabisulfite. Let stand for 30 minutes, and then wash with plenty of water. Small dry spill (un-polymerized) - Scrape material into clean, dry containers and cover. Minimize airborne dust generation.
Direct effects—Localized, non-immune-mediated adverse health effects on the skin, including corrosion, primary irritation, changes in skin pigmentation, and reduction/ disruption of the skin barrier integrity, oc curring at or near the point of contact with chemicals.
(To put these numbers in perspective, you'd consume around 150 µg of acrylamide in one large order of McDonald's fries, or 27 µg in a bowl of processed breakfast cereal.)
But this compound is, in fact, almost always present in coffee and potato chips, as well as many other foods such as cereal, French fries, peanut butter, even prune juice. Acrylamide levels are higher in things that are fried like French fries.
Although studies are reporting that cooking potatoes with new cooking equipment, such as an air fryer, may be a new opportunity to reduce acrylamide exposure (3, 17, 28, 29), the European Food Safety Authority (EFSA) reports that hot air fryers produce 30–40% more acrylamide than conventional deep fryers (30).
Potential Cancer-Causing Compounds in Doritos
Acrylamide, a compound formed during high-temperature cooking processes, has raised concerns regarding its potential carcinogenic effects. This substance is prevalent in carbohydrate-rich fried foods, including potato chips, with levels ranging from 330 to 2300 μg/kg.
Furthermore, acrylamide affects nerve endings, thereby causing central nervous system (CNS) symptoms, including hallucinations and convulsions, and peripheral nervous system symptoms, including tremors, weakness, ataxia, and sensory abnormalities [2, 5, 6].
Oats have the second highest acrylamide forming potential of rye, wheat, barley and oats. Several studies have found high levels of acrylamide in oat products that exceed the benchmark limits within the EU.
The level of acrylamide in green tea ranged from 27 to 110 ng/g db, and that in roasted green teas such as Houjicha ranged from 247 to 1880 ng/g db.
If acrylamide is kept protected from light, it is expected to be stable indefinitely at room temperature. After three weeks storage at 50 °C, there is no evidence of polymer formation and only slight yellowing occurs.
Based on what is currently known, it is not possible to determine the precise level of risk for human health from dietary exposure to acrylamide. However, research conducted by Health Canada and internationally indicates that french fries and potato chips typically contain the highest levels of acrylamide.
