Acrylamide in Drinking-water - World Health Organization

4.6 Carcinogenicity. Male and female Fischer 344 rats were given acrylamide at 0, 0.01, 0.02, 0.5 or 2 mg/kg of body weight per day in drinking-water for 2 years. In male rats receiving doses of 0.5 or 2 mg/kg of body weight per day, there was an increase in the frequency of scrotal, thyroid and adrenal tumours.

Sustainable ¦Â-cyclodextrin modified polyacrylamide hydrogel for highly efficient solar-driven water purification - ScienceDirect

Different from bound water and free water, intermediate water (IW) molecules have weak interactions with hydrophilic groups on the hydrogel. These weakly bonded water molecules require less energy to escape from the hydrogel, leading to a reduction in the water vaporization enthalpy, which helps to break the theoretical evaporation limit under the standard 1 sun illumination condition (1 kW/m

polyacrylamide - wikipedia

Polyacrylamide - Wikipedia

Polyacrylamide (abbreviated as PAM or pAAM) is a polymer with the formula (-CH 2 CHCONH 2 -). It has a linear-chain structure. PAM is highly water-absorbent, forming a soft gel when hydrated. In 2008, an estimated 750,000,000 kg were produced, mainly for water treatment and the paper and mineral industries. [1] Physicochemical properties [ edit]

Microbial degradation of polyacrylamide and the deamination product polyacrylate - ScienceDirect

Highlights ? Polyacrylamides are first deaminated to polyacrylates by microbial amidases. ? Remaining polyacrylates are more recalcitrant to degradation. ? Polyacrylamide degradation has mainly been reported for aerobic bacteria. ? With fungi the degradation is initiated by secreted lignin degrading oxidases. ?
