Polyacrylamide degradation and its implications
The hydrolyzed form of polyacrylamide (HPAM), a co-polymer of acrylamide and acrylic acid, is the most widely used anionic PAM in oil and gas development as well as in soil conditioning. 1,9,12,21
Acrylamide is a highly water soluble vinyl monomer formed from the hydration of acrylonitrile. 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.

(1994). Polyacrylamide review: Soil conditioning and environmental fate. Communications in Soil Science and Plant Analysis: Vol. 25, No. 11-12, pp. 2171-2185.
A review of the literature was conducted to bring to the forefront knowledge of polyacrylamide, its effectiveness in controlling erosion and its environmental fate. Polyacrylamide is a water-soluble, high molecular weight synthetic organic polymer that primarily interacts with the clay fraction of soils.
Irrigating with polyacrylamide (PAM) - Nine years
The purposes of this study were to test if soil erosion would be reduced by the presence of electrolytes in the erosive water, if use of an anionic polyacrylamide (PAM) as a surface spray or in
Although polyacrylamide (PAM) and its derivatives have many useful applications, their release in nature can have impacts on the environment and human health, thus bioremediation approaches for residual PAM are urgently needed. Biodegradation of PAM and its derivatives has been studied only in the last two decades, with most emphasis on acrylamide biodegradation.
Could We Spare a Moment of the Spotlight for Persistent
The environmental persistency of certain water-soluble polymers like PAM and polycarboxylate are well established. Direct environmental emissions of PAM come from its use as a flocculant in water treatment, as an agricultural soil conditioner, and increasingly, as a viscosity enhancer in oil and gas drilling and fracking.

Since 1950s, soil conditioners were primarily used
Acrylamide and polyacrylamide: a review of production, use
Acrylamide is a highly water soluble vinyl monomer formed from the hydration of acrylonitrile. 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.
The aim of this review was to summarize information and scientific data from the literature dedicated to the fate of polyacrylamide (PAM)-based flocculants in hydrosystems. Flocculants, usually composed of PAMs, are widely used in several industrial fields, particularly in minerals extraction, to enhance solid/liquid separation in water containing suspended matter.
Polyacrylamide Gel Crystals - Home Science Tools
These polyacrylamide crystals can absorb about 300 times their density of water. It is used in landscaping and agriculture to help retain soil water in dry climates, it is used for environment spill cleanup, it is used as an oil well drilling fluid, and it is even used to make soft contact lenses, to name just a few. Reviews & Questions
Polyacrylamide is a polymer that is formed from units of acrylamide, a known neurotoxin. However, Polyacrylamide itself is not considered to be toxic, but is a controversial ingredient because of its potential ability to secrete Acrylamide, according to Wikipedia. It is used in cosmetics and beauty products in two different forms, either as a
