Phosphorus limitation

It has been argued that phosphorus limits oceanic productivity on the million year time scale (Broecker, 1971). The reason is that essentially all phosphorus in the ocean is introduced by rivers and thus ultimately from the weathering of continental rocks. This flux is, in effect.

The PHOSter II system is only applicable to contaminants that can be biologically degraded. In addition, it is only effective in settings where microbial activity is phosphorus limited. At sites with high contaminant concentrations, product recovery may be required during the initial treatment stage. Hydraulic conductivity and moisture content also determine the effectiveness of the PHOSter II technology.

White Phosphorus. Limited information on the immunotoxicity of inhaled white phosphorus was located. As discussed in Section 2.2.1.2, decreased leukocyte levels were observed in workers exposed to an unknown concentration of white phosphorus via inhalation, oral, and dermal routes (Ward 1928). It is not known if the decrease in leukocyte levels would result in impaired immune function.

Back River Sewage Treatment Plant of Baltimore, MD, discharges to the Back River estuary. The State of Maryland imposes on its permit a total phosphorus limitation of 2.0 mg/L. Assuming all the total phosphorus converts to orthophosphorus and assuming the dilution effect of the estuary cannot be neglected, calculate the concentration of algae theoretically expected.
