Transfer and degradation of polyacrylamide-based flocculants in hydrosystems: a review
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
Polyacrylamide and its co-polymers are used as flocculants or coagulants wastewater treatment. For instance, according to a 2025 study from the United Nations University Institute for Water, Environment, and Health, about 52% of wastewater is

We tuned the lower critical solution temperature (LCST) of amphiphilic poly(N-isopropylacrylamide) (PNIPAAm) via copolymerization with a hydrophilic comonomer of N-hydroxymethyl acrylamide (NHMAAm). A series of copolymers P(NIPAAm-co-NHMAAm)
Interactive effects of biochar and polyacrylamide on decomposition of maize rhizodeposits: implications from 14 C labeling and microbial metabolic
Purpose The applications of biochar (BC) and polyacrylamide (PAM) may have interactive effects on carbon (C) dynamics and sequestration for improving the soil quality and achieving sustainable agriculture. Relative to BC and PAM, rhizodeposits

WHO/Europe | Nature and biodiversity play a vital role in protecting human health
Urbanization, land use, global trade and industrialization have led to profound and negative impacts on nature, biodiversity and ecosystems across the world. The ongoing depletion of natural resources not only affects environmental conditions
As long as we can afford to import food from other parts of the world, European food security may not seem to be at immediate risk, regardless of our support to European agriculture. But the choices we make will affect trade and global food
