. 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 booksh...

Since 2016, China has shut down over 1,300 metal smelting and processing companies as part of its national campaign to tackle soil pollution , particularly from toxic heavy metals like cadmium, lead, and arsenic . These metals are harmful to human health and the environment, often contaminating farmland and entering the food chain through crops. 📍 Key Details Regulatory Action : The closures were carried out under China’s broader environmental crackdown and regulations such as the Soil Pollution Prevention and Control Action Plan introduced in 2016. Affected Industries : These included small-scale, often unregulated smelters and processors that contributed significantly to soil contamination. Geographic Impact : Many of these plants were located near agricultural areas or densely populated regions, increasing the risk of exposure. Health Risks : Heavy metal contamination can lead to serious health issues including cancer, neurological damage, and kidney disease. Government Goals : Chi...

Education   DECEMBER 4, 2019 11:48 AM AEDT Share   Twitter   Facebook 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 ...

SYDNEY, N.S. — Residents of a government-run housing complex in Sydney are calling for urgent action to address ongoing issues with odours, rodent infestations, and safety hazards at their building. The seniors’ residence at 22 Tillock Drive, managed by the Cape Breton Island Housing Authority, has been the subject of repeated complaints since September, when approximately 20 tenants raised concerns about deteriorating living conditions. Among the primary issues reported are persistent unpleasant smells emanating from old and damaged carpets, as well as an ongoing mouse problem that has seen rodents appear in residents' beds, appliances, and common areas. Joe Dithurbide, one of the affected tenants, described the situation as unacceptable. "The smell’s been very bad—it’s just a stinky smell," Dithurbide said. "And the mice are still here. Just last week, I had to shut down my TV because they chewed through the wiring." In addition to odour control and pest conc...
