- 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.
- How dangerous is polyacrylamide (PAM)?
- 4.1.1. Polyacrylamide (PAM) As PAM is extensively used in our daily lives, it is essential to be aware of its potential hazards. Studies have indicated that PAM exhibits low or non-toxicity to humans, primarily due to the large sizes of polymers, which restrict their ability to penetrate the skin.
