Summer cyanobacterial blooms caused an elevation in pH (9 to ∼10.5) that lasted for weeks in the shallow and tidal-fresh region of the Sassafras River, a tributary of Chesapeake Bay (USA). Elevated pH promoted desorption of sedimentary inorganic phosphorus and facilitated conversion of ammonium (NH+4 ) to ammonia (NH3). In this study, we investigated pH effects on exchangeable NH+4 desorption, ...

To improve the interaction between penetration testers and their processes and technology, we need to understand the factors that affect decisions they make with ethical import.
