Fearing the invisible – selling nanotechnology hazards

The community is not getting as concerned about nanotechnology as expected (or perhaps as needed). There is the occasional scare and the Australian unions have relaunched their campaign on the hazards of nanotechnology manufacturing. There have been several articles about the potential ecosystem damage of nanotechnology in our waterways. Frequently, it can be heard that nanotechnology is the new asbestos.

Nanotechnology is a new technology and all new things should be used with caution. It is odd that none of the nanotechnology protests seem to be gaining much traction.

Part of the problem is that nanotechnology is invisible and how do people become concerned about the invisible? This is a point of difference from the asbestos comparison. Asbestos was turned into asbestos products – from dust to roofing. But nanotechnology goes from invisible to items such as socks. The public see new improved versions of common items, nanotechnology is used in familiar items, but the public does not see the nanotechnology and therefore does not comprehend nanotechnology as a potential hazard.

It may be useful to jump back before asbestos to look for new communication techniques for warning consumers about the invisible.

In 1998 Nancy Tome published “The Gospel of Germs“. Tome looks at the slow realisation in the first half of last century by the public that germs and microbes exist and can cause harm. She is not interested in the germs themselves but how society accepted their existence and how they reacted. This reaction – improved hygiene, infection control, disinfectant, etc – can provide us with some clues as to how society embraces the invisible, particularly if the invisible can make us sick.

Nancy Tomes wrote the book in the time when AIDS was new. But since then SARS is new, Swine Flu is new and other pandemics will become new to a generation who have only known good health and good hygiene. Now we are creating invisible things that we know can have positive benefits but we don’t know the cost of the benefit.

It is perhaps time for the OHS lobbyists to take a page or two from the public health promotion manual (and Tome’s book) and begin to explain rather than warn. Nanotechnology is not asbestos and the comparison is unhelpful. The application of nanotechnology will be in far more products than was asbestos and the nanotechnology is smaller.

If the lobbyists can make the invisible visible then progress will be much quicker.

Nanotechnology safety campaign (with Interview)

On 18 March 2009, Steve Mullins the OHS Officer with the Australian Council of Trade Unions presented a paper on nanotechnology hazards to the “Science Meets Parliament” forum. His concerns over worker safety are not shared by the nanotechnology industry as media reports show but, as Steve points out, nanotechnology hazards have some interesting parallels with asbestos.

Below are the concerns that Steve has over the nanotechnology manufacturing industry in Australia:

No regulatory acceptance that nanomaterials are more hazardous

No nano specific risk assessment or controls mandated

No nano specific monitoring equipment

No nano specific MSDS

No exposure levels

No labels

No requirement to inform

No health surveillance

No training

No nano specific PPE

Where nano specific risk management applied or promoted, end up trying to apply controls designed for larger material anyway

There is no coordinated approach

Cancer fears in Tasmanian school

Over recent years Australia has had its share of cancer cluster fears, most of which have not had a cause identified. Cancer clusters are one of the most difficult workplace hazards to manage for several reasons:

Worker’s fear for their health;
Management fears for its staff;
Some management worry about the related business costs;
Clusters can generate considerable media coverage; and
Noone knows what’s really going on.

An August 2008 case appeared in Tasmania and, therefore, got almost no coverage in other States, even though it occurred in a media-friendly venue, a school. The experts say that the incident is not technically a “cancer cluster” however semantics is the least of the worries for the participants and, in terms of safety management (and the management of any “outrage”), the differentiation is irrelevant.

In early March 2009, the investigation was completed and, sadly, no cause was identified. In 3 March, the Director of Public Health, Dr Roscoe Taylor, issued a media statement.

The investigation concerned the potential risks from electro-magnetic radiation from nearby power lines.

Dr Taylor found there was no statistical significance in the cancer rates of employees who had worked at the school

“Taking into account the lack of identifiable hazards, as well as the very small population we are dealing with, the most probable explanation for the numbers of cancers appears to be chance variation,” said Dr Taylor.

“This was a rigorous and thorough investigation and while we probably can’t provide staff with the absolute assurances and certainty they would have been looking for, I think the results of the analysis mean we can be fairly confident that there has been no serious threat to public or occupational health at the school.

More details and Frequently Asked Questions are available. A particularly useful factsheet on clusters is available HERE.

The Australian Broadcasting Corporation’s Health Report has an excellent podcast available in which cancer clusters in workplaces are discussed.

New evidence of the risks of using glyphosate

RoundUp and other glyphosate products are herbicides used domestically and commercially. New evidence supports the calls by the Institute of Science in Society for a ban on the use of these products.

Scientists pinpoint how very low concentrations of the herbicide and other chemicals in Roundup formulations kill human cells, strengthening the case for phasing them out, and banning all further releases of Roundup-tolerant GM crops

Research that shows an alternate perspective is available through Monsanto’s website.

This type of opinion or science war makes it very difficult for safety professionals to determine appropriate control measures when the evidence fluctuates however, as ever, protect to the lowest common denominator and eliminate the hazard wherever possible.

Eliminate the hazards

The first control measure on the “hierarchy of controls” is to eliminate the hazard. OHS consultants and professionals should always consider ways to achieve this. It may prove to be impractical, or politically unpopular, but it should always be discussed or recommended. Reports and submissions that do not consider this control measure can be considered invalid.

In late-January 2009, the organic farmers in Australia reminded the media that its farming members are developing a safer industry for the customer and the producer. This industry has boomed in Australia since the 1970’s in as a result of a desire and commitment to “eliminate the hazard”.

Interviews conducted by Biological Farmers of Australia (BFA) to help discover why producers ‘go organic’ reveal a high number of farmers consider the switch for the health of themselves and their families.

Rob Bauer (Bauers Organic Farm, Qld), one of Australia’s largest organic horticultural growers, says he turned to organic farming 27 ago after farmers in his area became ill with cancer.

He says he wanted to decrease health risks associated with synthetic farm chemicals.

“I started thinking about farming differently after growing up in the Lockyer Valley (Qld) where friends and family passed away in their fifties after years of intensive agrichemical production.”

He says neurological problems, tumours, and cancer were among the chronic diseases he watched take their toll on his local farming community.

“I wasn’t comfortable with producing food using harsh farm chemicals for consumers,” he says.

Steve Skopilianos, commercial lettuce producer from Ladybird Organics in Keilor (Vic) looked into organics when he started a family.

“We had been applying pesticide blends with no understanding of their effect on people and employees. There were times prior to organic conversion where I would not take my own produce home for my family to eat.”

Biodynamic producers of macadamias are happy to avoid high levels of agrichemicals typically used on the nuts.

“Working without a high exposure to synthetic chemical farm products is a weight off your mind,” says Marco Bobbert, from Wodonga Park Fruit and Nuts macadamia plantation (Qld), certified biodynamic since 1987.

He says direct chemical exposure could easily occur on conventional farms from accidents in production. “All it takes is a broken spray pipe.”

He says it is not just organic farmers who are concerned – “All farmers try to minimise their contact with chemicals on-farm. But organic production actively works toward negating that risk”.

Research has shown there is good reason for producers’ concern – a high exposure to some farm chemicals can lead to major health problems.

Particularly problematic substances include organophosphate insecticides and pesticides, which have been connected to several types of cancer, sterility and cognitive deficits (1).

The agrichemical endosulfan is one example of a highly toxic organochlorine cyclodiene) insecticide still in use in Australia.

Possible cancer cluster at fish hatchery

For several weeks News Limited papers have reporting weird goings on around a fish hatchery in Queensland. In a small area of Cooloothin Creek people living on properties neighbouring the Sunland Fish Hatchery have been noticing an increase in cancers. The latest victim is a hatchery foreman who has been diagnosed with bowel cancer.

The issue has been bubbling along since a two-headed fish larva was discovered around 11 January 2009. On 26 January 2009, the foreman has formally requested an investigation into a cancer cluster. The 26 January quotes cancer expert, Bruce Armstrong.

Professor Armstrong said the fact there was more than one type of cancer would normally militate against a cluster. But the deaths and health problems among chickens, horses and dogs — as well as the fish — were extremely worrisome. “Clearly, there does seem to be an ecological issue here,” he said.

He suggested an investigation could help determine if the agrichemicals posed a threat to humans.

Local residents produced a video about the issue of crop spraying which is available on YouTube.

This current case will increase the pressure on government’s for increased regulation of farm chemicals and delivery systems.

UPDATE – 28 January 2009

Queensland’s Primary Industries and Fisheries Minister Tim Mulherin has established a taskforce to investigate the Noosa fish abnormalities. It’s first meeting will be on 28 January 2009.

It includes private aquaculture veterinarian Dr Matt Landos, who says the available evidence points to farm chemicals.

According to a ministerial media release Dr Landos said

“I am extremely pleased that the minister is keen to progress this issue and welcome the opportunity to work with the minister and the State Government. We need to consider interim alternative chemicals and farming practices in co-operation with macadamia farmers, to provide improved safety for aquatic animals and sustainable macadamia production.”

The ministerial release also said that

“claims of a cancer cluster in the area are a matter for Queensland Health to consider.

Queensland Health has said the need for an investigation into an alleged cancer cluster will be determined once specific information is received from the community about their health concerns.”

SafetyAtWorkBlog will be following the taskforce’s progress.

Indonesian Mines & Depleted Uranium

As in most professions during time in occupational health and safety, one meets amazing people. One that SafetyAtWorkBlog cherishes is Melody Kemp.

Melody is an ex-pat Australia who currently resides in Laos. As well as working on OHS matters throughout the Asian region she is also the author of the excellent OHS publication Working for Life: Sourcebook on Occupational Health for Women, a free download.

In 19 December 2008 Melody had an article printed in Asia Times Online concerning the social impacts of a proposed mine on the small Indonesian island of Lembata. In this era of corporate social responsibility, safety professionals have a broad brief which covers many industrial, corporate and environmental responsibilities and it is often company behaviour in far-flung outposts of the corporate structure or the world that indicates a clearer picture of corporate and safety culture.

Melody’s article is highly recommended for those with a social conscience, for those in the mining sectors and for those whose companies have Asian operations.

In 2003, Melody wrote an article on the health risks of the use of depleted uranium for Safety At Work magazine (pictured below). That article can be accessed HERE.
