DEMOLITION: Dust swirls around central Christchurch after the implosion of Radio Network house in August 2012.

OPINION: Professor IAN SHAW looks at why demolition dust might be harming our health and explores whether the risk is worth worrying about.

I'm sitting in my office watching a building being deconstructed (the new euphemism for "demolished") with clouds of dust floating on a warm nor'wester towards my open window.

My first thought is "Close the window!", quickly followed by "I hope the deconstruction people have thought through the dust- associated risks."

So, what are the risks associated with dust and why has it become an issue? After all, we've been exposed to dust forever and it's done us no harm. Or has it?

Looking back into the annals of human health risk discoveries, the one that marks a significant change in thinking was Richard Doll's discovery in the 1950s that smoking is associated with lung cancer.

We all accept this now, but in the 1950s it was rather controversial.

If you look at the geographical mortality statistics for lung cancer in the UK it is clear that more people died of lung cancer in Lancashire, Manchester, Newcastle, Yorkshire and parts of Cornwall and Wales.

The common factor for these areas was mining.

Dust a post-earthquake hazard

Working or living close to demolition sites increases risk of dust-related health problems, says a toxicology professor.

Professor Ian Shaw, of the University of Canterbury, said attempts to reduce demolition dust in Christchurch were "variable" and often ineffective.

Residents and workers had been exposed to a lot more dust than in "pre-earthquake days", increasing health risks, he said.

"For most of us this is a very small increase but for demolition workers the risk is much greater."

Asbestos was of concern, but it was "a well-known dust carcinogen and is taken very seriously by building deconstructors".

Mr Shaw said fine respirable concrete dust particles, however, could also lead to potential health risks.

"Studies on workers exposed to concrete dust have shown that crystalline silica is the problem and that it is associated with a broad array of lung diseases, including silicosis and lung cancer," he said.

Demolition of concrete buildings "inevitably produces crystalline silica dust".

The effect of the toxin on health depended on dose, Mr Shaw said.

People who worked with concrete dust were in the top exposure bracket, while the general public were at the bottom.

Mesothelioma battle for family

DEMOLITION victims presently seeking refuge in roadside shanties in communities in Lugait, Misamis Oriental, can no longer stand their situation as they pleaded the municipal and provincial government leaders for transparency on their relocation.

We are asking if the local government of Lugait can present us a timeframe regarding our relocation so we wont live in danger in the roadside, the position letter by Alyansa ng mga Biktima sa Demolisyon sa Calangahan (Albidec) read.

The letter was addressed to Governor Yevgeny Emano and Lugait mayor Wellie Lim.

Albidec is the organization of the demolition victims in the villages of Calangahan and Biga in Lugait town.

Also, Albidec wants to have a more spacious lot area of 100 square meters per family at the relocation site.

But while the planning for the relocation is ongoing, Albidec also asked for water connection and makeshift port for their boats so they can go back to fishing, their main source of income.

At present, the whole area is fenced preventing them from using the shore as port for their small fishing boats.

Albidec also requested that the list of families for relocation would come from the organization to prevent opportunists (people whose homes were not demolished) to get a parcel of land from the relocation site.

The organization, through the same letter, urged the local government of Lugait to provide them with the promised aid, and not to solely rely on the aid from the provincial government.

Meanwhile, Christine Cabiasa, provincial information officer, said last week that the municipal and planning officer of Lugait and the owner of the relocation site conducted a survey.
