Abstract:

Methylamines are low molecular weight organic nitrogen compounds found both in marine and terrestrial environments. In seawater, methylamines are commonly found in algae and fish and are also products of degradation, excretion and metabolism by marine bacteria and animals. Quaternary amines which are osmoregulators in many marine biota, are thought to be precursors of the methylamines. However, the production, concentrations, and consumption uptake rate of methylamines in seawater are not well known. The ambient concentrations of methylamines have been biogeochemistry has been difficult. I developed a method to measure three methylamines in natural waters in concentration ranges from nanomolar to micromolar concentrations. In this technique, the methylamines are concentrated and desalted using diffusion across a teflon membrane.
