Soil organic carbon (SOC) is one of the most critical factors determining soil quality or fertility. Recent survey has reported the severe degradation of SOC by soil erosion in agricultural fields throughout the world. To maintain soil quality
- Does anionic polyacrylamide biodegrade?
- ent only.1 BACKGROUNDAnionic polyacrylamide is the copolymer of acryl mide and acrylic acid. No studies on the environmental fate of polyac ylamide are available. As a high-molecular weight, water-soluble polymer, it is not expected to biode rade or bioaccumulate. Anionic polyacrylamide has a low acute toxicity concer
- What is anionic polyacrylamide (Apam)?
- 1. Introduction Anionic polyacrylamide (APAM) is a kind of organic high-molecular polymer with high hydrophilicity and viscosity, which is easily dissolved in water [ , , ].
- Is anionic Polyacrylamide a Tier 1 chemical?
