Polyacrylamide (PAM) is a term
used to identify a class of water
soluble. high molecular weight. synthetic
organic polymers. All PAM
molecules have a backbone structure
comprised of acrylamide compounds.
C3115NO, modified via the loss of a C
to C double bond that are linked together
into long chains. The term
PAM is generic. describing a group
of compounds. each different in its
chemical and physical properties due
to different chain lengths and minor
alterations in some of the acrylamide
subunits (Lent: and Sojka. 1994).
Water-soluble PAMs are effective
flocculants. used as settling agents in
food processing. water treatment.
mineral processing and paper production
(Barvenik, 1994).
PAM is essentially non-toxic to organisms.
though one impurity present
in very low concentrations is a known
human neurotoxin (Seybold, 1994).
In the environment, the carbon backbone
of PAM is resistant to microbial
attack but susceptible to physical
breakage and chemical degradation
from either free radicals or ultraviolet
radiation. Seybold (1994)
concluded that PAM posed no environmental
threat and that it could be
used to reduce irrigation-induced erosion
and improve soil physical properties.
Characteristics of PAM and
several of its promising applications
in agriculture have been reviewed
recently by Lentz and Sojka (1994)
and Seybold (1994).
