“…Previous study (Brown et al 1980) has shown that no degradation of AMD occurred in distilled or sea water after Adsorption of AMD on activated carbon was found to be a rapid process (inferior to 4 h), and no adsorption on kaolinite, montmorillonite, or exchange resins was found during a test period of 168 h (Brown et al 1980). In our study, no degradation of AMD was found during the test period.…”

“…For AMD initial concentrations between 100 and 10 4 μg/L, no significant adsorption of acrylamide on sludge, sediments, and clays was found after 24 h of contact (Brown et al 1980). On the other hand, it has been highlighted that the percentage of acrylamide adsorption was varying between 1 and 22 %, when the initial AMD concentration was ranging from 5000 to 50 μg/L, respectively (Arrowood 2008).…”

Polyacrylamides are polymers used in many fields and represent the main source of release of the highly toxic acrylamide in the environment. In this work, a simple, rapid, and sensitive analytical method was developed with HPLC/MS/MS and direct injection for acrylamide analysis in water and adsorption samples. AFNOR standards NF T90-210 and NF T90-220 were used for the analytical method validation and uncertainty estimation. Limit of quantification (LOQ) for acrylamide was 1 μg/L, and accuracy was checked at three acrylamide levels (1, 6, and 10 μg/L). Uncertainties were estimated at 34.2, 22, and 12.4 % for acrylamide concentrations at LOQ, 6 μg/L, and 10 μg/L, respectively. Acrylamide adsorption on clays (kaolinite, illite) and sludge was then studied as a function of pH, time, and acrylamide concentrations. Acrylamide adsorption on kaolinite, illite, and sludge was found to be very weak since adsorption percentages were inferior to 10 %, whatever the pH value and the initial acrylamide concentration. The low affinity of acrylamide for clays and sludge is likely due to its hydrophilic property, small size, and charge neutrality.

“…Mobility of AMD in soils has been little studied. Adsorption of AMD on kaolinite, montmorillonite and anionic, cationic, and hydrophobic resins is insignificant (Brown et al 1980), at acrylamide concentrations between 500 µg L -1 and several mg L -1…”

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. These polymers can contain residual monomer of acrylamide (AMD), which is known to be a toxic compound. This review focuses on the mechanisms of transfer and degradation, which can affect both PAM and residual AMD, with a special attention given to the potential release of AMD during PAM degradation. Due to the ability of PAM to adsorb onto mineral particles, its transport in surface water, groundwater, and soils is rather limited and restricted to specific conditions. PAM can also be a subject of biodegradation, photodegradation, and mechanical degradation, but most of the studies report slow degradation rates without AMD release. On the contrary, the adsorption of AMD onto particles is very low, which could favor its transfer in surface waters and groundwater. However, AMD transfer is likely to be limited by quick microbial degradation.

“…AMD was completely degraded within 5 days after applying 500 kg PAM kg -1 garden soil (Shanker et al, 1990). Lande et al (1979) applied 25 kg PAM kg -1 soil and reported that the half-life of AMD in agricultural soils was 18-45 h. Degradation may be slower in cooler more sterile waters, in sandy soils, or soils with low respiration rates because of temperature, soil water content, or other factors slowing microbial metabolism (Brown et al, 1980(Brown et al, , 1982Conway et al, 1979;Croll et al, 1974;Davis et al, 1976). Metcalf et al (1973) andNeely et al (1974) concluded that because of the ease with which AMD is metabolized by biological organisms and otherwise degraded, it is not likely that it can bioaccumulate to any extent in the food chain.…”

“…Thus even if there existed a small probablility for the AMD production from polymer chain scission, it would decrease drastically with time. Other research shows that any AMD present in microbiologically active soil environments is rapidly metabolized as an N source by several soil microorganisms including Nocardia rhodochrous, Bacillus sphaericus, Rhodococcus sp., Arthrobacter sp., and Pseudomonas putrefaciens (Abdelmagid and Tabatabai, 1982;Arai et al, 1981;Brown et al, 1980;Croll et al, 1974;Lande et al, 1979;Shanker et al, 1990;USEPA, 1985). noted that the end products resulting from PAM decomposition would not be AMD, even if the first step of PAM decomposition yielded the monomer.…”
