Rapid, simple, and inexpensive determination of PAM in solution could be a very useful tool for determining its fate in environmental applications. Our results suggest that the turbidimetric method by hyamine is relatively simple and efficient in determining PAM concentration in soil extracts with low organic carbon (

Biodegradation of Polyacrylamide and Its Derivatives – Springer
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. Microorganisms have been shown …
