Diffuse phosphorus pollution is commonly remediated by diverting runoff through treatment wetlands to sequester phosphorus into soil layers. Much of the sequestered phosphorus occurs in organic forms, yet our understanding of its chemical nature is limited. We used NaOH-EDTA extraction and solution 31P NMR spectroscopy to speciate organic phosphorus sequestered in a large treatment wetland (STA...

The use of micro-glass electrodes sensitive to the activity of selected cations has permitted a direct measurement of intracellular ionic activity , e. g., the activity of hydrogen ion in a single crab muscle fiber (CALDWELL 1954), and in a single squid giant axon (CALDWELL 1958, SPYROPOULOS 1960), the activity of sodium and potassium ion in a single squid giant axon (HINKE 1960). With a micro-...

Plants are an abundant natural source of effective antibiotic compounds. Phytomedical investigations of certain plants haven't still been conducted. One of them is Najas minor (N. minor), an aquatic plant with confirmed allelopathy. Research conducted in this study showed the influence of water and ethyl acetate extracts of N. minor on microorganisms, in the view of chemical profiling of volati...
