Excessive use of pesticides and herbicides is a major environmental and health concern worldwide. Atrazine, a synthetic triazine herbicide commonly used to control grassy and broadleaf weeds in crops, is a major pollutant of soil and water ecosystems. Atrazine modifies the growth, enzymatic processes and photosynthesis in plants. Atrazine exerts mutagenicity, genotoxicity, defective cell

Occurrence of a New Generation of Disinfection Byproducts
A survey of disinfection byproduct (DBP) occurrence in the United States was conducted at 12 drinking water treatment plants. In addition to currently regulated DBPs, more than 50 DBPs that rated a high priority for potential toxicity were studied. These priority DBPs included iodinated trihalomethanes (THMs), other halomethanes, a nonregulated haloacid, haloacetonitriles, haloketones

Biofouling of Polyamide Membranes: Fouling Mechanisms
1. Introduction. Since its beginnings in the early 1960s, membrane-based desalination has become a leading technology in municipal and industrial settings, currently outpacing traditional thermal technologies [].As of June 2025, membrane-based desalination accounted for just under 2.5 million m 3 /day of annual contracted capacity, while thermal technologies accounted for less than 0.5 m 3

Fish industry waste: treatments, environmental impacts
The highest activities of cathepsin L‐like enzymes were found at pH 10.5, whereas cathepsin B‐like enzymes were highly activated with acid treatment . The best textural properties (breaking force, deformation) were recorded at pH 11 and 2, whereas the worst texture at pH 10.5 (Kim et al. , 2003) .

- What factors affect the flocculation effect of cationic polyacrylamide (CPAM)?
- Cationic polyacrylamide (CPAM) is a commonly used flocculant for water treatment. Factors that affect the flocculation effect and can be controlled manually include the type and dosage of CPAM, wastewater pH, stirring time and settling time, and their reasonable setting is critical to the flocculation effect of CPAM.
- What is cationic polyacrylamide (CPAM)?
- Cationic polyacrylamide (CPAM) is one of the most frequently used flocculants with high intrinsic viscosity and charge density. This flocculant is a water-soluble acrylamide-based polymer having cationic quaternary ammonium groups .
- Does cationic polyacrylamide flocculate Phaeodactylum tricornutum?
- However, Nguyen et al., observed high flocculation efficiency of marine microalgae Phaeodactylum tricornutum with a cationic polyacrylamide flocculant (FO3801). The discrepancy in the literature suggested that a future flocculation study using one type of polymer with multiple marine species.
- How cationic polyacrylamide (PAMC) is prepared?
- Flocculation and mechanism was discussed based on zeta potential and pH analysis. A novel cationic polyacrylamide (PAMC) with various cationic monomer contents were prepared by copolymerizing acrylamide (AM) and methacryloxyethyl trimethyl ammonium chloride aqueous solution (DMC) through low-pressure ultraviolet (UV) initiation.
