- Is polyacrylamide contaminated with acrylamide?
- Polyacrylamide is of low toxicity but its precursor acrylamide is a neurotoxin and carcinogen. Thus, concerns naturally center on the possibility that polyacrylamide is contaminated with acrylamide.
- Is acrylamide a human carcinogen?
- The National Toxicology Program’s Report on Carcinogens considers acrylamide to be reasonably anticipated to be a human carcinogen, based on studies in laboratory animals given acrylamide in drinking water.
- Does dietary acrylamide increase cancer risk?
- So far, reviews of studies done in groups of people (epidemiologic studies) suggest that dietary acrylamide isn’t likely to be related to risk for most common types of cancer. But ongoing studies will continue to provide new information on whether acrylamide levels in foods are linked to increased cancer risk.
- Does aqueous acrylamide monomer cause heavy skin contamination?
- The study authors reported that heavy skin contamination by aqueous acrylamide monomer was common among the workers. An acrylamide level of 410 mg/L was measured in the water in which three of the workers washed their hands.
