Acrylamide in Environmental Water: A Review on Sources, Exposure, and Public Health Risks | Exposure and Health

Acrylamide and polyacrylamide (PAM) are used in diverse industrial processes, mainly the production of plastics, dyes, and paper, in the treatment of drinking water, wastewater, and sewage. Besides inorganic form, acrylamide is formed naturally in certain starchy foods that were heated to cook a temperature above 120 ¡ãC for elongated time. Researches in rats have demonstrated that acrylamide

Role of Polyelectrolytes in the Treatment of Water and Wastewater

10.3.2.3.1 Anionic Polyacrylamide (PAM) High molecular weight carboxylic acid polymers derived from polyacrylamide are used as flocculant in water industries. Copolymers with anionic structure are prepared by copolymerization of acrylic acid and acrylamide or its salts, or by polymerization of acryl amide followed by partial hydrolysis as shown in Fig. 10.8 (Haydar and Aziz 2009 ).

3.3.2. Characteristics of slime water. The main characteristics of slime water were as follows: high concentration, high content of fine particles, high ash content, many negative charges on the surface of particles. These particles kept stable dispersion in the water due to the repulsion of the homoelectric charge.

Physiological Response of Daphnia magna to Linear Anionic Polyacrylamide: Ecological Implications for Receiving Waters - Water, Air, & Soil Pollution

Linear anionic polyacrylamide (LA-PAM) is being considered as a soil amendment to reduce seepage and infiltration in unlined earthen canals. While polyacrylamides have been extensively used for potable water treatment, dewatering sewage sludge, coal and mine processing, paper manufacturing, and agriculture, little is known about its ecological impact to aquatic ecosystems. Acute toxicity (LC50
