Historically, the environmental risk of PAM was thought to be relatively low because the polymer is very large and non-toxic and would be strongly bound to soil particles, while the residual monomer and other degradation products are highly biodegradable and unlikely to persist in the environment.

BACKGROUND Anionic polyacrylamide is the copolymer of acrylamide and acrylic acid. No studies on the environmental fate of polyacrylamide are available. As a high-molecular weight, water-soluble polymer, it is not expected to biodegrade or bioaccumulate. Anionic polyacrylamide has a low acute toxicity concern to aquatic organisms.

Best Practices Guidance for the Use of Anionic Polyacrylamide

Polyacrylamide (PAM) Chitosan What is Anionic Polyacrylamide? • High molecular weight, water soluble molecule formed by polymerization of negatively charged acrylamide co-monomer. • PAM aids solid-liquid separation by causing suspended particles to bind and form larger aggregates. • The process is known as polymer bridging.

Considering the volume of polyacrylamide produced, these materials have been heavily scrutinized with regards to environmental and health impacts. Polyacrylamide is of low toxicity but its precursor acrylamide is a neurotoxin and carcinogen. Thus, concerns naturally center on the possibility that polyacrylamide is contaminated with acrylamide

We found that median lethal concentrations (LC50s) of polyacrylamide ranged from 411.7 to >1000 mg/L for glochidia and from 126.8 to >1000 mg/L for juveniles. All LC50s were orders of magnitude greater (2-3) than concentrations typically recommended for turbidity control (1-5 mg/L), regardless of their molecular weight or charge density.
