Hannah Holmes is a Maine native who revels in the arcane technologies and techniques found in Maine's famously old housing stock. Previously a journalist, her writing clients have included National Geographic, The Discovery Channel Online, and The Old House Journal. Her realty clients have included a wildlife rehabilitator seeking three bedrooms, two baths, and accommodations for a large alligator.
As a real estate broker, her operating principle is that knowledge is power. To that end her goal in any transaction is to provide clients with all the information they need to make a financially sound and durable decision. A swift analyst and communicator, she is a formidable ally in today's fast-moving market.
Hannah is the author of four popular science books with subjects ranging from the science of personality, to the unique wildlife habitat provided by suburbs, and dust. Yes, dust. Google if you don't believe me.

The secret life of dust : from the cosmos to the… by Hannah Holmes
So I bought myself a rather nice "dissecting" microscope and a friend asked what I was using it for. "Oh, examining the dust from the vacuum cleaner" I replied. Well it's what you do isn't it? And I've long been curious about dust. How much of it is falling on us at any one time? Where does it come from? Am I getting dangerous levels of dust by living near to a freeway? Does it cause asthma? So I had quite a few questions before i even began the book. And, I must admit I was put off by the "accessible-science" writing style....lot's of folksy descriptions of people ..and overwrought prose....for example: “Hayley Duffel was a typical student, from Yorkshire, England. She was slim and wore her thick, dark hair in a sensible ponytail. With a quirky grin she introduced herself as a dust girl”. And then this: “The Phillipines islands……sit atop a seam in the planet. In fact, the entire Pacific Ocean is underlain by a particularly combative section of the earth’s crust. Its rock melting conflicts with neighbouring plates have earned the region the nickname the “Ring of fire”.”
All a bit much…. And given the size of Pacific, probably incorrect in the wider sense…. Yes there is a ring of fire but it’s not everywhere in the Pacific.
So in the initial stages I was getting so annoyed with the style that I almost gave up. But I'm glad that I soldiered on. The style was the same but there is some really interesting content in there. Though you do come up against the perennial problem of popularising science: how do you make the figures meaningful. So we are told that as the tires on your car wear down, 25,000 tons of rubber dust go into the air. And, hitting the brakes sends 35,000 tons of brake lining dust into the air each year in the USA. OK this sounds like a lot of pollution ...but if half of it falls to the ground within 5 min and the rest is mixed up with, say, the first 1000m of atmosphere the 25,000 tons of rubber dust becomes 0.0013 gm per cubic m of air. And this doesn't sound like quite so much to me. (In fact, it's significant because it's added onto all the other micro dust in the atmosphere and if it's all in the form of micro particles then we are talking about 1.3 micrograms of dangerous dust per cubic m of air. ......And there is no safe lower level of these particles). Anyway, it's hard to grasp the significance of such figures...and a lot of such figures are cited.
So where does dust come from? Well a whole lot of places really......from outer space comes a steady downpour.....from our deserts comes dust that crosses both the pacific from China and the Atlantic from Africa. And plants put out pollen and fungal spores and trees give off chemicals like isoprene, terpene, alcohol and formaldehyde, I've already mentioned from the roads and from engines. Add in dust from fires and volcanoes,..plus household dust (especially from mites and insect sheddings). If you're breathing really clean air you are taking in at least a billion and a half pieces of dust into your nose and mouth every day. (Sounds like a lot). And the industrial dusts of today (especially from diesel engines) are smaller than the dusts of the past and can penetrate the deepest recesses of our lungs.As one epidemiologist says..."air pollution kills people".
And there are some especially nasty dusts: mercury, asbestos, silica, coal dust (a black lung fund is doling out money to 200,000 people per year...both diseased miners and their families). But just about any mining dust can cause problems (I remember in Esperance, Western Australia, a few years ago birds were dying ...which was traced back to lead in the dust from a mine but it didn't stop there ....it was found that the lead and nickle were on the roofs and rainwater tanks of the entire city). But Hannah Holmes goes on to tell the horror stories from talc dust, wood dust, cotton dust, wheat flour dust (with its propensity to explode), synthetic fibre dust and dusts from intensive animal raising...especially poultry and pigs. Then there are cooking dusts ...especially bad for those who cook over open fires in confined spaces, pesticide dusts, mould clouds and spores from fungi.
Homes devotes quite a bit of energy to drawing a link between asthma and dusts but doesn't quite make the connection. There are obvious links but there always seem to be exceptions that don't fit the theory. For example, kids who grow up in dirty environments appear to have less asthma than kids who grow up in clean environments ......are the developing immunity? She finishes with a homily on the dusts from cremation...and some ashes being rocketed into space.
Altogether quite fascinating. A power of information there. Sufficient for me to overlook her overwrought prose and folksy introductions to the experts. Happy to give it 4.5stars.… (more)
