  • What are acrylamide and polyacrylamide used for?
  • Acrylamide and polyacrylamide (PAM) are used in diverse industrial processes, mainly the production of plastics, dyes, and paper, in the treatment of drinking water, wastewater, and sewage. Besides inorganic form, acrylamide is formed naturally in certain starchy foods that were heated to cook a temperature above 120 °C for elongated time.
  • What is polyacrylamide (PAM)?
  • Polyacrylamide (PAM) is a long chain, linear, water soluble polymeric substance formed from acrylamide (C 3 H 5 NO) subunits, has a high molecular weight of typically from few 1000 to 20 × 10 6 g/mol, and has a very high viscosity in aqueous solutions, depending on the concentration and the degree of polymerization (Sojka et al. 2007).
  • 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. Considerable effort is made to scavenge traces of acrylamide from the polymer intended for use near food.
  • What is the commercial use of acrylamide?
  • The major commercial use of acrylamide is the formation of polymers. In the environment acrylamide has a high mobility in soil, may travel great distances in ground-water, is biodegradable, and is not absorbed by sediments or affected by water treatment. It is absorbed by all routes of animal exposure.
