  • What is the global polyacrylamide market size?
  • The global polyacrylamide market size was valued at USD 4.5 billion in 2018 and is projected to expand at a CAGR of 6.2% from 2019 to 2025 . In volume, this represents an output of about 2.5 million tons. Polyacrylamide, or PAM, is made from the acrylamide monomer.
  • Are polyacrylamides safe?
  • McCollister, in 1965, established the safety of polyacrylamides in the public health aspect for many applications wherein small amounts may possibly occur in the food or drink of animals or human subjects . Those results were confirmed recently by Hensen et al. and Farkas et al. on marine fish species.
  • Does polyacrylamide depolymerize on acrylamide monomer?
  • Indeed, King et al. and Smith et al. confirmed the innocuity of polyacrylamide, whereas acrylamide monomer is classified as neurotoxic. In another study led on polyacrylamide used in agriculture, Anh et al. showed that polyacrylamide does not depolymerize on toxic acrylamide monomer, despite a misleading title .
  • Is acrylamide a radioactive polymer?
  • No uptake of acrylamide by the plants or any other form of radioactivity was observed. The molecular weight of the polymer was drastically reduced when extracted from the soil matrix and was degraded biologically by at least 20% in two years, giving a degradation half-life of 5.4 years .
