Clustered and 'declustered' water
Peroxide and radical production in water
One of the difficulties in putting forward novel ideas for the structure of water is that the scientific press has been mistaken before and prefers to shuffle forward in the almost known rather than take big steps into the less well known.
The first water-related mischance, that the scientific literature fell into,
concerned polywater (originally called anomalous water); a dense
(> 1.3 g cm-3) and viscous (20 x increased) form of
'polymeric' water that was reported, in the 1960s, to form in narrow
(< 20 μm) capillaries [122].
The effects were later shown to be due to unforeseen impurities [123].
Some made unsubstantiated claims that stopcock grease and human sweat caused the original effects. However, some
samples contained just silica, dissolution of which was not anticipated
at that time as quartz vessels hold water without noticeable dissolution.
There were also delays in analyzing the polywater samples due to
the minuscule volumes available (< μg)
and consequentially low silica contents (< 10-4 μg
as then determined). Recognition that the properties of anomalous
water were due to impurities was not before it had generated a considerable
theoretical literature, both for and, less embarrassingly particularly
early on, against. There was a positive outcome to this work in
that it did stimulate much work on water at that time and showed the importance of materials dissolved from water containers. However, the episode seems to be usually
remembered with discomfiture and probably reduced the publications concerned with water structure over the subsequent few years as many scientists avoided the area to avoid any similar pitfall. Since then, high-density liquid water
has been verified to exist (at low temperatures [16]), but this is unrelated
to any of the polywater samples. Polywater is still researched but
on the basis of the properties of concentrated electrolyte silica
condensates. [Back to Top

More recently, IE (ice formed
by electric field forces) crystals (mm x 100 nm diameter)
have been proposed to form around ions due to their electric
field [124, 125a].
It is also proposed that these 'spherically symmetrical crystals'
can be broken by shaking to seed further crystal formation,
although this seems more likely to cause the loss of water
molecules from the surface (peeling) rather than the release
of fragments. The ions must be dilute (< 10-5 M) to prevent ions 'interacting' (reducing the electric field
gradient) before crystals have time to form. The crystals
are proposed to have 20% lower dielectric than water. These
IE crystals are now thought to be completely artifactual
with the term 'crystals' now being replaced by 'water clusters'.
Even with this change, these
theories have not been confirmed [125b]
and are not generally accepted and no ice
phase is formed above 0°C below 632 MPa. The presence
of extensive hydrogen-bonded clusters in less-than-pure water
containing additional hydrophobic solutes, however, is quite
reasonable. [Back to Top ]
Also recently promoted is 'HHO' a material produced from
water by electrolysis that is supposedly different of the
expected electrolytic mixture.b This process apparently breaks the (inviolable) laws of thermodynamics
and is backed by a paper that is full of scientific and numerical
errors [938].
The claims for this material (that is, HHO) should be
examined with great care, and are now correctly reported as totally erroneous [938b], although this is disputed [938c]. [Back to Top ]
An interesting development is the sale of 'neowater'
(water containing a minute amount of nano-sized, 10-50 nm,
particles of barium titanate) for various biotechnological processes.
It is suggested that the particles organize the surrounding
water and stabilize gaseous nanobubbles (more properly called nanocavities) resulting in the change in the liquid's properties.
Scientific support for this is beginning to appear [1129, 1172]. [Back to Top ]
Very recently there has been an explosion of Internet sites and sales outlets concerned with 'declustered' water and its production. Generally these concern the promotion and sale of relatively expensive water preparations for their health benefit. These appear to be related to Lorenzen's 'microclustered' water [164] or Hayashi's 'microwater' [111]. Lorenzen prepared such water by passing steam across a magnetic fielda (using magnetite), exposing it to light/radiation with a wavelength between 610 nm and 1 mm (preferably monochromatic at 640 nm) and adding materials such as 3 - 4 ppm metasilicate, up to 1% yeast cells and gas under pressure. His patents claim such water may be diluted by between 103 and 1020 times. A similar product (Willards water) also uses silicates and surfactants [193], whereas 'Penta' water uses acoustical cavitation and oxygen saturation [496]. Hayashi prepared his water by electrolysisb using the reduced and oxidized streams for different purposes. Although cluster size can be determined from the shift in the 17O NMR resonance signal in line with its reduction with increasing temperature, in some cases it seems to have been determined by means of changes in the width (at half peak height) of the 17O NMR resonance signal from above 100 Hz to below 100 Hz. Other conditions being equal this width is expected to give a measure of the strength of the clustering as motionally-hindered water has faster relaxation kinetics and hence should give a greater 17O NMR resonance signal width (for example, the width also decreases with increasing temperature). However these samples are not pure water samples as they have high (supersaturated) gas concentrations and may contain other additives. The widths do not appear to change reproducibly as Hayashi reports a width for impure water of 105 Hz but Lorenzen reports the width for distilled and triple distilled water as higher at 130 Hz and 115 Hz respectively. Unfortunately the data reported by Lorenzen and Hayashi is sparse and does not include any statistical data or precise experimental conditions. Also there does not seem to be much other data reported in the literature concerning the effect of solutes on the width of this resonance or its reproducibility. Other uncontrolled factors, such as pH, will also have a major effect. Independent NMR analysis [1516] fails to confirm any useful correlation with structure. Nor is there any unanimity on what cluster size any reduction in the width might indicate. Other unanswered questions concern (a) whether it is the strength or extent of the hydrogen bonding that is important, (b) if extent is important, is it the mean number of hydrogen bonds each water molecule participates in or the mean cluster size of fully satisfied hydrogen bonded water molecules that is important, (c) if strength is important, is it the mean strength of all the bonds around a water molecule or only the strongest of these, (d) what is the effect of the distribution of hydrogen bond strengths (or extents), and (e) how long do any effects lastc. More importantly, controlled clinical trials are lacking so that all sales patter extolling the health-giving virtue of such water involves the (scientifically irrelevant and basically biased) use of testimonials.
In the light of the increased promotion of 'special' water
preparations, it is important to take notice that there are
definite and proven health benefits from simply drinking
more water. [Back to Top ]
Free radicals (for example, hydroxyl radicals) and free (hydrated) electrons can be introduced into water by techniques such as electrochemistry, ultrasonics or ultraviolet radiation [497], but their lifetime is likely to be very short and health benefits unproven except in terms of disinfection. Water may also be split by electrolysis or mechanical methods such as stirring with a catalyst [739], to give H2 and O2 and some associated free radicals such as the highly reactive hydroxyl radical. In particular, low concentrations of hydrogen peroxide (H2O2) may be produced from water (H2O) by any process that moves clusters of water relative to each other such as mechanical vibration [1066]

The presence of such active oxygen species and gases or their mixtures in water may
have significant and long term 'memory' effects. [Back to Top ]
a It has been shown that a high
magnetic field has an insignificant effect on the equilibrium
content of dissolved oxygen (< 0.3 mM at 20°C under
atmospheric conditions) but does significantly enhance its
dissolution rate [176].
High electric fields (E ~109 V m-1)
reduce water's permittivity [616],
which will increase the solubility of gases. Water may be
supersaturated with oxygen (~3-6 mM; equivalent to less than
a breath of air in each liter of supersaturated water) under
pressure. It should be noted that, left by itself, degassed
water may take days to re-equilibrate with atmospheric gases
and as even small amounts of dissolved gases are reported
to have relatively large effects on the structuring of water
[560], it is
not unreasonable to suppose that artificially induced metastable
conditions with higher gas content may last for some time.
Drinking of oxygenated water does give a transient moderate
increase in serum ascorbyl radicals (with unknown consequences),
an affect that disappears with regular consumption [422].
It will not, however, significantly add to the body's oxygen
intake and has no apparent harmful or health-promoting effects
[772]. Production
of singlet oxygen (1O2;1Δg+,
electrons paired in their π-antibonding
molecular orbitals, cf. 3O2,
normal triplet oxygen, 3Σg-,
where two electrons are in equivalent but separate π-antibonding
orbitals with the same unpaired spin) during processing may
cause the dissolved peroxide concentration to increase via
the water-catalyzed reaction (x.1O2+2H2O
(1–x).3O2+2H2O2)
[1199] with possible consequential pharmacological effects. Interestingly
singlet oxygen takes part in antibody-catalyzed water oxidation
similarly producing triplet oxygen and hydrogen peroxide [624].
However, as the lifetime of the singlet oxygen is expected
to be in the μs range when dissolved
upwards towards 45 min in the (low pressure) gas phase, singlet
oxygen molecules are not expected to remain in processed bottled
water. [Back]
b At the electrolytic electrodes, water molecules are oriented, hydrogen bonds are broken and water‘s reactivity is increased. Anodic water (oxidizing, from the positive electrode) is biocidal and acidic and may contain H2O2, ·O2-, ·OH, 1O2, plus HOCl and Cl2 if NaCl is present. Cathodic water (reducing, from the negative electrode) has been used for washing and sanitizing [1277] and may be alkaline and contain H2. Such H2 may form a supersaturated solution and be present in nanobubbles (10-1000 nm diameter nanocavities) stabilized by salts (for example, Na+ and Cl-) present [974]. Extensive electrolysis will also change the isotope ratio which may have an effect [424]. [Back]
c There is one report that magnetically treated water (also from the same laboratory, electromagnetically treated water) retains a significantly changed effect on fungal spore germination for at least 24 hours [174]; however other parameters (for example, reduced dissolved oxygen levels) may be responsible for such effects. Mechanically-induced hydrogen bond breakage, caused by shaking (succussion) when producing homeopathic solutions, has been reported to last for weeks [336]. [Back]
