I also
wanted to consolidate the "information point" I made from the
floor on parentheses as much or more for the "public" as those
advised by Tom Blundell for "science". Consensus on
soundness is problematic for both of course, likewise dispositional
distortion (deliberate or otherwise) but I had in mind more dissemination
of dramatised dogma which in recent times has more often than not gone
inversely with rigour ~ spiking I think is fashionably apt for
selective slanting to secure the "right result". Speed
(pejoratively safety) cameras provide a paradigm but GM-ganic, F&M,
vCJD prognostications (probably also atmospheric carbon) have all furnished
happy hunting grounds for careerist "epidemonologists" ~ my
meldewismic moanings (via meta-moniker) meander around this morass. Sir
Tom would have been the right target for this stuff but I failed to retrieve
his @ddress so was hoping you'd pass on my comments just in case he's really
interested.
As for
the focus of your meeting, had it been an appropriate occasion I
would have suggested Silsoe's presentation provided a perfect platform for
positing optimal applications insofar as present low drift technologies entail
bigger drops that are incompatible with not just protective efficacy but
minimal residue as soil / water contaminants. I mention because there is a
technology that emerged from DTI SMART Awards a decade ago which was laboratory
verified at that time to possess an operational envelope ranging from halved
drift with standard drops to halved drop diameters with standard drift ~ and
with efficacy going mainly as interstitially rendered drop number, halved
drop diameters could even imply as much as 7/8th reduction in active volume.
I cannot
comment more because the extent to which these findings transfer to field
performance is presently the "subjudice" subject of a DEFRA
project led by others under commercial confidentiality restrictions ~
although the laboratory results have long been on the public record in
international patents approved a decade ago. Well worth a thought though, being
well within the interest remit portrayed at the meeting ~ ditto a further
related one on the extent to which existing best practice benchmarks prescribed
in so-called LERAP ratings really are relevant for optimal utilisation of
noxious substances in the sense defined above ~ as minimal compromise between
drifting and dumping. In giving no recognition to the morphological compliance
of crop realities LERAP is unduly biased to favour dumping which is not
incorporated in the approval assay ~ just another thought.
Use of
chemicals to cap costs is self-evidently worthwhile in furtherance of
staple crop production, whose accessibility is crucial to maintenance /
restoration of dietary health amongst poorer people denied access to
overpriced posh alternatives that are in any case are not more nutritionally
beneficial than the conventionally sourced bulk constituting 90%+ sales at 50%-
unprotected prices. Inevitable downside of course has been drift
persecution for the unfortunate few who actually reside within risk range of
spraying activities. My personal view would be it's a matter of common experience
that neither forecasting nor modelling of wind (like weather) can adequately
capture the complicated realities of statistical excursions and topographical
exceptions.
With this
stuff being so noxious that any direct deposition is unreasonable it seems to
me an elementary answer would be to a institute a regulatory requirement
stipulated spraying excluded from a quadrant or so (radiused maybe to 10s
metres) with approval subject to wind vectored away from agreed vulnerable
targets and in excess of some small speed (few mph) adequately accommodating
inevitable localised intermittent reversals including induction by equipment
turning or skew motions, etc. A very simple unambiguous rule is
what's needed here, not a pile of probabilistic pontification culminating only
in confused complication. There you go ~ that's it and if you like it then I'm
sure you'll communicate it through the right channels, hopefully including Sir
Tom at least in respect of the first point. Many thanks. Sincerely.
PS
Circulating copy to a couple of people who expressed interest in the SMART
technology hoping they'll get back to confirm it ~ maybe after glancing at the
SA (SPRAY Aeolian) link via my meta-moniker. Thanks.
My
interest stems from a decade on defence gizmos in material and dynamical issues
of underwater acoustics, former on design and evaluation of non-ionic polymeric
cocktails as powerful clathrating agents for stilling of surface waters, latter
on their stabilisation in dispersed deepwater foams. These things deploy as
monolayers and thus are truly nano unlike virtually all stuff masquerading
under that pseudonym for EC moneymaking purposes.
The link
to health relates to an unsuccessful bid for EC-fp2 money where interest was
triggered by decay of coastal vegetation (palms particularly) in vicinity of
Toulon, consistent with typical transportation ranges of marine aerosol by sea
breezes (100km). Toulon hosts French nuclear submarine facilities and we
conjectured non-nuclear maintenance nasties might provide a causative
connection ~ and that’s why we didn’t get the money of course! Comparable
concern was unofficially expressed at the time of the Sizewell Inquiry as to
whether sea breeze transportation of post catastrophe radionuclide aerosol had
been properly addressed ~ key here being restricted vertical dispersive
dilution delivered by air flows buoyantly capped to 100m depth or so.
A further
strand to this story is provided by an EC-fp5 project which I catalysed and
still hold background IP for automated water watching to monitor streakiness
whose density, intensity and longevity provides an index metric for ecological
health of the water column in terms of biodigestive rates and capacities. This
thing of course was spawned from the defence stuff, an important consequence
connection being made in terms of natural biopolymeric caging and micro
(nowadays nano!) layer accumulation of anthropogenic organics and metallics
from industrial activities and power stations as well as more routine stuff
sourced from sewage discharges and harbour operations etc.
Scavenging and concentration amplification capacities of these monolayers
awesomely resides in the order of inverse fractional depths, say 10^9 for
1-10nm skins riding on 1-10m columns at least as an indicator for low
solubility substances strongly partitioned by hydrophobicity (like metals and
organics). Streakiness is a ubiquitous facet of all natural waterscapes and the
project demonstrated reliable retrieval and extraction of these features using
primitive video and algorithms although didn’t get so far as to draw the
biodynamical inferences needed for commercial credibility.
The final
strands in my story are the UK being a hotspot for the explosive appearance and
expansion of asthma and eczema incidence since the ‘70s and the emergence of
coastal vegetation stressing in East Anglia akin to that reported for the
Riviera 20 years ago. My conjecture conveyed to the Asthma Society but sadly
not even acknowledged is that exotic toxics routinely used in the offshore oil
industry were also first introduced in the ‘70s and have been escaping ever
since as inevitable trace releases during routine operations, also as leachates
from seabed residues and of course from accidental escapes. Barium based muds and
organic mobilisers are employed as are powerful surfactants which could serve
as amplifying and transporting agents carrying sea skin concentrates shoreward
via surface stress from ambient sea breezes until eventually aerosolised into
breaking waves to become airborne for final phase carriage overland.
Bearing
in mind that UK sea breezes drive wind patterns more days than not and their
penetration has been logged to 200km inshore (ie washing the entire country)
these jigsaw pieces might be thought to provide a prima facie platform
deserving investigation as possible explanation for notified deteriorations in
vegetative and human health. Indeed, the highest incidence of asthma and oil
activity is in Scotland… just a thought, one which I’ve been touting for
several years but not seen anything in print to show it’s yet been taken as
seriously as seemingly deserved.
I’ll
close by reminding you of the nano links here, from monolayer source through
aerosol content extending to submicron residues from volatile mixtures ~
although I thought the traditional wisdoms in inhalation dynamics were that
>100mic is “harmless” because of early deposition and that <10mic is
“harmless” because of retained suspension. On the other hand that picture looks
a tad naïve when surface active agents add hitherto neglected complications
across the board from inbound transport to ultimate fate on membrane linings,
especially seeing as the latter respond dynamically to such stuff used as
dispersants for inhaler aerosols.
It’s a
fascinating puzzle, the more so because it hasn’t yet received the recognition
it seemingly deserves. My motive isn’t entirely passive ~ I’m always on the
lookout for involvement in projects but being unaffiliated I need alliances
with credible academics before funding agencies will even consider my ideas ~
nowadays affiliation secures success and intrinsic merit counts for nought.
Thanks
for your time ~ I’ll probably miss your “debate” having seen sound scientists
shredded by pop politicos in that earlier notorious thing on gemganic nonsense
when FoE morons and their media mates hijacked the agenda to claim popular
public support and screw the good guys. A distinguished old FRS told me
afterwards the distortion destroyed his lifetime faith in communication as
educational extension ~ in reality of course the public at large (ie 95%)
doesn’t give a toss beyond soap and soccer, merely reflexively returning the
“right” replies to Pavlovian pejorative poseurs. Democracy destroys
sensibility, certainly any demanding more than an iota of scientific
sophistication. So good luck Peter even though my story sits squarely on
Vyvyan’s side of this fence!
