‘What do old books smell like?‘—Preserving smells as important cultural heritage

.

A ‘Historic Book Odour Wheel‘ which has been developed to document and archive the aroma associated with old books, is being presented in a study in the open access journal Heritage Science. Researchers at UCL Institute for Sustainable Heritage created the wheel as part of an experiment in which they asked visitors to St Paul‘s Cathedral‘s Dean and Chapter library in London to characterize its smell.

The visitors most frequently described the aroma of the library as ‘woody‘ (selected by 100% of the visitors who were asked), followed by ‘smoky‘ (86%), ‘earthy‘ (71%) and ‘vanilla‘ (41%). The intensity of the smells was assessed as between ‘strong odor‘ and ‘very strong odor‘. Over 70% of the visitors described the as pleasant, 14% as ‘mildly pleasant‘ and 14% as ‘neutral‘.

In a separate experiment, the researchers presented visitors to the Birmingham Museum and Art Gallery with an unlabelled historic book smell – sampled from a 1928 book they obtained from a second-hand bookshop in London – and collected the terms used to describe the smell. The word ‘chocolate‘ – or variations such as ‘cocoa‘ or ‘chocolatey‘ – was used most often, followed by ‘coffee‘, ‘old‘, ‘wood‘ and ‘burnt‘. Participants also mentioned smells including ‘fish‘, ‘body odour‘, ‘rotten socks‘ and ‘mothballs‘

Cecilia Bembibre, heritage scientist at UCL and corresponding author of the study said: “Our odour wheel provides an example of how scientists and historians could begin to identify, analyze and document smells that have cultural significance, such as the aroma of in historic libraries. The role of smells in how we perceive heritage has not been systematically explored until now.”

Attempting to answer the question of whether certain smells could be considered part of our cultural heritage and if so how they could be identified, protected and conserved, the researchers also conducted a chemical analysis of (VOCs) which they sampled from in the library. VOCs are chemicals that evaporate at low temperatures, many of which can be perceived as scents or odors.

Combining their findings from the VOC analysis with the visitors‘ characterizations, the authors created their Historic Book Odour wheel, which shows the chemical description of a smell (such as acetic acid) together with the sensory descriptions provided by the visitors (such as ‘vinegar‘).

Cecilia Bembibre said: “By documenting the words used by the visitors to describe a heritage smell, our study opens a discussion about developing a vocabulary to identify aromas that have cultural meaning and significance.”

She added: “The Historic Book Odour Wheel also has the potential to be used as a diagnostic tool by conservators, informing on the condition of an object, for example its state of decay, through its olfactory profile.”

The authors suggest that, in addition to its use for the identification and conservation of smells, the Historic Book Odour Wheel could potentially be used to recreate smells and aid the design of olfactory experiences in museums, allowing to form a personal connection with exhibits by allowing them to understand what the past smelled like.

Before this can be done, further research is needed to build on the preliminary findings in this study to allow them to inform and benefit heritage management, conservation, visitor experience design and policy making.

China shuts 1,300 metal firms since 2016 in soil clean-up

BEIJING/SHANGHAI (Reuters) - China has shut more than 1,300 heavy metal enterprises since 2016 as part of a long-term plan to curb widespread chronic soil pollution, an environment ministry official said on Friday.

Soil pollution is one of China’s biggest and most expensive environmental challenges. The last nationwide survey in 2014 showed that around 16% of its land - an area the size of Mongolia - was contaminated to varying degrees by fertilizers and pesticides, heavy metals, plastic and other chemicals.

But Su Kejing, director in charge of soil pollution at the environment ministry, told a Friday briefing he was confident China could meet a target to make around 90% of contaminated farmland safe for agriculture by the end of next year.

The cost of remediating contaminated soil ranges from 500 yuan ($71) to as much as 2,000 yuan per mu (1 mu = 0.67 square metres), putting China’s total bill in the trillions of yuan. Su said the focus, though, would be on tackling risks, rather than cleaning up every single site.

“It is one-sided to think soil pollution prevention and treatment are expensive,” he said. “The priority is preventing the pollution and controlling risks from pollution. Only a small amount of land will really need to be remediated.”

As well as shutting 1,300 firms involved in producing and processing heavy metal, China has also “rectified” nearly 700 enterprises working with cadmium, a major source of pollution in rice, Su said. He also said that converting arable land to less pollution-sensitive crops would also help mitigate risks.

Tackling soil and water pollution is a major part of China’s efforts to boost agricultural productivity. China is trying to squeeze more food out of its farming belts, especially as its urban populations soar.

A 2015 government study estimated that heavy metals had contaminated at least 10 million hectares (25 million acres) of farmland, reducing annual grain production by 10 billion kg (22 billion pounds) a year.

Beijing published a plan in 2016 that set a target of bringing soil pollution under “preliminary control” by 2020 and starting to cut contamination levels by 2030, but financing has been a major challenge.

Although Beijing has set up a fund to help pay for its clean-up projects, with 28 billion yuan made available over the last three years, it has struggled to create incentives and financing mechanisms, especially in old industrial or rural regions where property values are too low to make remediation worthwhile.

“In the next stage we will work with other departments to encourage private capital and enterprises to inject funds into soil remediation,” Su said.

Sewer technology passes sniff test

University of Queensland

monitoring technology to identify potential odour and corrosion hotspots in urban sewerage networks has been adopted by ASX-listed environmental management technology firm Envirosuite.

The SeweX technology uses mathematical modelling to predict odour and corrosion hotspots and to optimise mitigation strategies in sewer mains, and was developed by researchers from UQ’s Advanced Water Management Centre.

UQ’s technology transfer company UniQuest negotiated a licence agreement with Envirosuite.

AWMC Director Professor Zhiguo Yuan said the technology was developed in response to needs identified by the water industry.

“Corrosion and odour problems in sewers are most often caused by sulphate-reducing bacteria in sewer biofilms that produce hydrogen sulphide,” Professor Yuan said.

“Hydrogen sulphide is released into the atmosphere above the wastewater, causing odour problems, and is converted by sulphide-oxidising bacteria into sulphuric acid, which is corrosive to concrete sewer pipes.

“Sewer networks can include many kilometres of sewer pipe and various topographical elements, such as rising mains, gravity mains, pumping stations and manholes. It is practically difficult to physically inspect all these structures to identify corrosion issues, making modelling a more efficient and cost-effective alternative.”

Envirosuite Chief Scientist Robin Ormerod said corrosion in sewer and drinking water systems was estimated to cost almost $1 billion every year in Australia.

“This technology will keep towns and cities with reduced odour, and will save wastewater operators millions of dollars every year in operational costs and consumer complaint management,” Mr Ormerod said.

“This partnership is an exciting one. Bringing together tools like the UQ-developed SeweX, with Envirosuite’s digital technology focus, is hugely powerful.”

UniQuest CEO Dr Dean Moss said SeweX incorporated complex algorithms into its model to cleverly predict odour and corrosion hotspots across sewerage networks.

“It is fantastic to see UQ research helping an Australian company like Envirosuite to drive key improvements to the way water utilities manage wastewater to benefit communities right across the country, and even globally,” Dr Moss said.

Envirosuite will integrate SeweX into its product suite in early 2020.

Sydney seniors fed up with apartment building told odour, rodent issues to be fixed

A group of seniors in Sydney, N.S., has been promised that issues with odours and rodents in their government-run apartment building will be addressed in the next few weeks.

The building at 22 Tillock Drive is managed by the Cape Breton Island Housing Authority.

In September, a group of 20 residents complained about rodents and strong smells from old carpets. Several said mice were showing up in their beds and even their toasters.

Staff met with them on a couple of occasions. Last Friday, they met with Sydney-Whitney Pier MLA Derek Mombourquette.

Resident Joe Dithurbide said they told their MLA the problems are continuing.

George Mortimer/CBC

"The smell's been very bad, it's just a stinky smell," said Dithurbide.

As for the mice, he said they made their presence known as recently as a week ago.

"My TV shut down completely," said Dithurbide. "I called people, they were good enough to come in, they went out in the hallway and mice ate my wire, the TV wire, so the mice are still here."

The residents said they are also concerned about a first-floor emergency exit door that's been blocked by snow at times.

Mombourquette said a tender has already gone out for the carpet replacement and he expects the work will begin in early January.

He said a pest control company has also been called in and the emergency exit will be checked.

"There was a list that I took from the meeting, so any request that comes through, we ensure that it gets to housing," said Mombourquette.

'I'll believe it when I see it'

In an email to CBC News, Housing Nova Scotia, which oversees the provincial housing authorities, said staff have met with each tenant individually to discuss their concerns.

Dithurbide said although he appreciates the promise of help, he's not yet counting on anything.

"I'll believe it when I see it," he said.

SMELL OF THE DAY: PEACH BLOSSOM

Smell of The Day is about noticing and appreciating the smells around me. Just one smell. It might be a perfume, a fragrant flower, the odour of something cooking, an unpleasant smell. All smells are equal. All smells are interesting. All smells affect us. Smell of The Day posts will feature one smell that made an impact on me that day.

SMELL OF THE DAY: PEACH BLOSSOM

It’s late winter, and this year it’s been the kind of long, cold winter that I hope will end soon. Today I went for a walk in the cold, rugged up so much that I could barely move in multiple layers and my knee-length down coat. With wind chill the temperature was a brisk 2º celsius. I know that some parts of the world get much colder, but for a girl raised in sunny South Australia, 2 degrees is a shock to the system. The walk was challenging and cold, yet uplifting and energising. To reward myself at the end of it, I grabbed the secateurs and cut myself three stems of newly opened blossom from the old peach tree.

Peach blossom

Blossom is so beautiful – leafless stems dotted with clumps of flowers, both in bloom and still in bud – it creates a kind of instant, effortless Ikebana in the vase. I couldn’t resist placing them on top of my piano with my Japanese kokeshi dolls. Blossom reminds me of Japan, of the Hanami cherry blossom festivals held there in spring, and of Ukiyo-e woodblock prints.

Peach blossom and kokeshis

Peach blossom smells like honey. It’s sweet, almost in a sickly way. The smell is strong and as I sniff the blossom deeply my nose intuitively pulls back, feeling drunk with the pleasure of this overwhelming and narcotic scent, and perhaps anticipating a sneeze. The smell reminds me of sugar syrup bubbling on the stove, waiting to be made into tooth-breaking toffee. If I sniff a little less deeply, I detect a scent a little like that of sweet hay, grassy and dry. Peach blossom reminds me that the bees will soon arrive and harvest the precious, deliriously sweet pollen from this very tree. It makes me happy and reminds me that winter will soon be over. Peach blossom is the promise of spring in a vase.
