Marine platforms range of their sensitivities to perturbation. Perturbation might be insidious - similar to expanding eutrophication of coastal parts - or it can be dramatic - comparable to a reaction to an oil spill or another coincidence. weather switch may perhaps take place incrementally or it can be abrupt, and atmosphere resilience could be a posh functionality of the interactions of the standards and species mediating key biogeochemical approaches.

Phenylalanine hydroxylase activity has been determined by electrochemically monitoring the conversion of tetrahydrobiopterin to dihydrobiopterin 273). Another monooxygenase, tyrosine hydroxylase, has been determined by detecting the DOPA produced by the enzymatic reaction 274, 275). Formation of DOPA has also been monitored electrochemically to determine the activity of L-aromatic amino acid decarboxylase 276). Other enzymes involved in catecholamine metabolism which have been determined electrochemically include: dopamine-13-hydroxylase 277~, phenylethanolamine-N-methyltransferase 278~, and catechol-O-methyltransferase 279~.

The limited selectivity of in vivo electrochemical techniques is also a disadvantage at present. However, the ability to make rapid measurements for continuous sampling to follow the dynamics of neurochemical processes more than offsets the disadvantages of the technique. It cannot be over emphasized that at present only in vivo electrochemical measurements provide a method of monitoring rapid changes in neurotransmitter concentration. Another advantage of in vivo electrochemical techniques is that tissue damage is less severe than with alternative perfusion techniques.
