Agriculture 2-43 image: Guidance for Federal Land Management in the Chesapeake Bay Watershed In laboratory studies, alum reduced ortho-P in dairy wastewater 93-99 percent at rates less than three g alum/L. Ortho-P was reduced to one mg P/L or less by a combination of alum and polyacrylamide (PAM) treatment (Jones and Brown 2000). Oh et al
Hepatic Proteome Analysis of Atlantic Salmon (Salmo salar
Pharmaceuticals are pseudopersistent aquatic pollutants with unknown effects at environmentally relevant concentrations. Atlantic salmon (Salmo salar) were exposed to Acetaminophen: 54.77 ± 34.67; Atenolol: 11.08 ± 7.98, and Carbamazepine: 7.85 ± 0.13 μg·L −1 for 5 days.After Acetaminophen treatment, 19 proteins were differently expressed, of which 11 were significant with respect to
The coagulant used was aluminum sulfate (Al 2 (SO 4) 3) and the anionic polyelectrolyte FX AS1 of FAXON Company, (Novo Hamburgo, Brazil, CAS:25987-30-8). For coagulation-flocculation assays stock solutions of 50.0 mg L -1 of coagulant (Al 2 (SO 4 ) 3 ) and 80.0 mg L -1 of polyelectrolyte were prepared.
