“…As for the extract stability, acrylamide is not stable in contact with raw plant tissue or soil microorganisms (Bologna et al 1999). Cooking halts the biodegradation of acrylamide, so its stability in an extract is dependent on pH, exposure to light, reactive co-extractives and microorganisms.…”

Isotope dilution liquid chromatography coupled with electrospray ionization tandem mass spectrometry (LC-MS/MS) was applied to the quantification of acrylamide in chocolate matrixes (dark chocolate, milk chocolate, chocolate with nuts, chocolate with almonds, and chocolate with wheat best element). The method included defatting with petroleum ether, extracting with aqueous solution of 2 mol l À1 sodium chloride and clean-up by solid-phase (SPE) with OASIS HLB 6 cm 3 cartridges. Acrylamide was detected with an Atlantis dC 18 5 mm 210 Â 1.5 mm column using 10% methanol/0.1% formic acid in water as the mobile phase. The analytical method was in-house validated and good results were obtained with respect to repeatability (RSD < 3.5%) and recovery (86-93%), which fulfilled the requirements defined by European Union legislation. The acrylamide levels in chocolate were 23-537 mg kg À1. Therefore, the method was successfully used for the quantitative analysis of acrlyamide in various chocolate products.

“…A great number of methods have been developed to analyse quantitatively the acrylamide monomer, especially in sugar (Tekel et al 1989), field crops (Bologna et al 1999) and mushrooms (Castle 1993). The majority are classical methods based on HPLC or GC techniques.…”

Three relatively new applications for controlling wind and water erosion using polyacrylamide copolymers arc described that take advantage of their ability to stabilize and add structure to soil. In the first application, low concentrations of anionic, high purity polyacrylamide (PAM) eliminates sediment in runoff water by more than 90% when added to irrigation water at 10 ppm, or at a rate of 1 to 2 kg ha-1 per irrigation. Lab-furrow tests were utilized to characterize the role of molecular weight. charge, and ion concentrations in applying PAM during irrigation. In the second application, PAM is applied at construction sites and road cuts at rates of 22.5 kg ha -2 (tenfold higher rates than in irrigation control) resulting in reduction in sediment runoff by 60-85% during (simulated) heavy rains. Finally, a formulation of PAM mixed with aluminum chlorohydrate and cross-linked poly(acrylic acid) superabsorbent at a ratio of (6:1:1) has been applied to create helicopter landing pads that minimize dust clouds during helicopter operation. This formulation was specifically developed to minimize dust clouds during landing of helicopters in fine, and soils such as those potentially encountered in the Middle East. A biodegradable alternative to PAM, acid-hydrolyzed cellulose microfibrils, was tested in lab-scale furrows and was less effective than PAM at similar concentrations, but show promises. Microtibrils reduce sediment run-off in lab-furrow tests by 88% when applied at eight-to tenfold the concentration of PAM.

“…Environmental and safety considerations of anionic PAMs have been reviewed (Barvenik, 1994;Bologna et al, 1999;Seybold, 1994). The most significant environmental effect of PAM use is its erosion reduction, protecting surface waters from sediment and other contaminants washed from eroding fields.…”

“…Furthermore, AMD is easily metabolized by microorganisms in soil and biologically active waters, with a half life in tens of hours (Lande et al, 1979;Shanker et al, 1990). Bologna et al (1999) showed that AMD is not absorbed by plant tissues, and apparently breaks down rapidly even when injected directly into living plant tissue.…”

"Capsule": Polyacrylamide preparations show promise in reducing flow of sediments, nutrients and microorganisms from animal production facilities. AbstractWaste streams associated with a variety of agricultural runoff sources are major contributors of nutrients, pesticides and enteric microorganisms to surface and ground waters. Water soluble anionic polyacrylamide (PAM) was found to be a highly effective erosion-preventing and infiltration-enhancing polymer, when applied at rates of 1-10 g m-3 in furrow irrigation water. Water flowing from PAM treated irrigation furrows show large reductions in sediment, nutrients and pesticides. Recently PAM and PAM + Ca0 and PAM + Al(SO4)3 mixtures have been shown to filter bacteria, fungi and nutrients from animal wastewater. Low concentrations of PAM [175-350 g PAM ha-' as PAM or as PAM + Ca0 and PAM + Al(SO 4) mixture] applied to the soil surface, resulted in dramatic decreases (10 fold) of total, coliform and fecal streptococci bacteria in cattle, fish and swine wastewater leachate and surface runoff. PAM treatment also filtered significant amounts of NH4, PO4 and total P in cattle and swine wastewater. This points to the potential of developing PAM as a water quality protection measure in combination with large-scale animal feeding operations. Potential benefits of PAM treatment of animal facility waste streams include: (1) low cost, (2) easy and quick application, (3) suitability for use with other pollution reduction techniques. Research on the efficacy of PAM for removal of protozoan parasites and viruses and more thorough assessment of PAM degradation in different soils is still needed to completely evaluate PAM treatment as an effective waste water treatment. We will present analysis and feasibility of using PAM, PAM + Al(SO4)3 , and PAM + CaO application for specific applications. Our results demonstrate their potential efficacy in reducing sediment, nutrients and microorganisms from animal production facility effluents. Published by Elsevier Science Ltd.
