What is ionic polyacrylamide (PAM)?

Anionic polyacrylamide (PAM) has been sold since 1995 to reduce irrigation‐induced erosion and enhance infiltration.

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.

Does polyacrylamide reduce labor and material costs?

In construction applications, PAM reduces labor and material costs. Polyacrylamide can be cost effective in rain-fed agriculture under certain management regimes such as on soils highly susceptible to crusting and breaking the cycle of crusting-low organic residue production-crusting.

Is polyacrylamide a good solution for soil degradation?

Soil degradation is a significant problem throughout the world. Use of soil amendments, including anionic polyacrylamide (PAM), is one of many options for protecting soil resources. Polyacrylamide has been the focus of a substantial amount of research in the 1990s.

Does polyacrylamide reduce erosion?

Polyacrylamide provides substantial savings while controlling erosion and increasing vegetation establishment on construction sites. Using PAM in conjunction with other erosion control measures may also provide economical erosion control and warrants further investigation.

Is polyacrylic acid a product of Pam degradation?

Hayashi et al. (1994) suggested that the simple compound polyacrylic acid might be another product of PAM degradation under some conditions, which can also be metabolized by microorganisms.
