- Is acrylamide monomer a carcinogen?
- Although the PAM used in environmental systems has a very high MW, it is well known that PAM can undergo degradation by a variety of mechanisms, significantly increasing its mobility and potentially leading to the release of acrylamide monomer, a known toxin and potential carcinogen.
- What happens if acrylamide reacts with chlorine?
- The double bond in the acrylamide monomer present in the original polymer solution can react with chlorine to form -ClC-COH- 114, 116, 124 and possibly chloroform, which is a health concern at concentrations >50 mg/L 125.
- Does acrylamide cause Maillard browning?
- Reports that acrylamide is present in foods formed during their processing under conditions that also induce the formation of Maillard browning products heightened interest in the chemistry, biochemistry, and safety of this vinyl compound.
- Is acrylamide a risk factor for human health?
- Further research needs in each of these areas are suggested. Neurotoxicity appears to be the only documented effect of acrylamide in human epidemiological studies; reproductive toxicity, genotoxicity/clastogenicity, and carcinogenicity are potential human health risks on the basis of only animal studies.
