Asbestos is the generic term for a group of naturally occurring fibrous minerals with high tensile strength, flexibility, and resistance to thermal, chemical and electrical conditions. Asbestos fibers are of high-tensile strength, flexible, heat and chemical resistance, and good frictional properties. Cement is the most essential raw material in any kind of construction activity. Ceramics also known as fire clay is an inorganic, non-metallic solid article, which is produced by the art or technique of heat and subsequent cooling. Limestone is a sedimentary rock, mainly composed of calcium carbonate CaCO3.

As the first public event to address the Greek asbestos legacy, the Hellenic Asbestos Conference attracted wide support and media interest, putting asbestos firmly on the national agenda. The participation of delegates from diverse subject disciplines ensured that this was not a run-of-the-mill academic gathering.
Greek trade unionists, medical specialists, general practitioners, medical students and others discussed a range of asbestos-related topics with doctors, scientists, lawyers, architects, victim support workers and campaigners from sixteen countries. The difference of opinions and clash of viewpoints that occurred produced a vibrant atmosphere in which constructive discussions took place. At a press briefing on October 29, Professor Panagiotis Behrakis, President of the Hellenic Thoracic Society and President of the Conference, told reporters that the purpose of the forthcoming meetings was to explore the repercussions of occupational and environmental asbestos exposure in Greece and identify ways of minimizing risks.
He said that the scientific and medical communities have an obligation to raise asbestos awareness amongst at-risk groups and the public. Laurie Kazan-Allen, the Coordinator of IBAS, pointed out that in the s, Greece was the 7 th largest asbestos producer in the world with the chrysotile white asbestos mine in Kozani, Northern Greece producing an average of 70, metric tons a year.
Although most of the asbestos was exported, some of it was used in asbestos-cement factories in Greece. The fact that Greece was both a producer and user of asbestos might explain why it is one of only two European Union Member States not to have banned asbestos.
Kazan-Allen hoped that the meeting would stimulate the national debate on asbestos. Categorizing the legacy of asbestos as an "invisible public health disaster," Dr. Barry Castleman, an eminent U. According to Dr. Castleman, the scale of the asbestos tragedy in the U. In Europe there will be at least , deaths from asbestos cancer in the current thirty-year period. There is no doubt that people in Greece will die from these diseases.
To illustrate this point, Dr. It was believed that his exposure to asbestos took place during his years in the merchant navy; he died the day after the press conference. The opening ceremony of the conference was held during the evening of October 29 and included a short program of speeches, followed by the opening of a photographic exhibition and a gala reception.
Welcoming delegates to the first session of the conference, Professor Behrakis emphasized the need for doctors to be involved in discussions with the Government, the Trade Unions and the injured.
He expressed the gratitude of all the delegates when he thanked Dr. Professor Stavros Constantopoulos, one of the key organizers of the conference, expressed his satisfaction at the broad range of support which the conference had received and thanked Laurie Kazan-Allen, the IBAS Coordinator, for her role in this event. The representative of the Greek General Confederation of Labor, Andreas Kollas, said that too often Greek trade unionists die from asbestos-related diseases just as they retire.
Although the Greek asbestos mine in Kozani is now closed, Mr. Kollas confirmed, the asbestos-cement factory in Thessaloniki will stay open until the EU asbestos deadline. It was unfortunate, the trade unionist said, that Government agencies responsible for protecting workers and the public from exposure to asbestos have not yet acted in an effective and coordinated manner. Conference delegates were delighted to hear the speech by Professor Evangelos Solinareos, an eminent doctor who has been studying occupational disease in Greece for decades.
Professor Solinareos recalled some of his cases and spoke of unsuccessful attempts to conduct X-ray examinations of workers, most of whom were in fear of losing their jobs. Detailing, the growth of the anti-asbestos movement, she said:. For over fifty years, international asbestos producers have used the considerable resources at their disposal to maximize sales and generate profits despite mounting evidence that exposure to asbestos caused disabling and fatal diseases.
Kazan-Allen reported that Chile, Argentina, most of Western Europe and much of Brazil have now prohibited the use of chrysotile, other forms of asbestos having been banned previously. In Asia and the Far East, the situation is changing. The Government of Vietnam has announced plans to ban chrysotile in High-level discussions about unilateral bans are proceeding in Japan and Malaysia. The previous system ensured that asbestos claims were rejected; nowadays compensation claims for workers, their families and the public are routinely paid by negligent corporations and Government agencies.
Senator Ruers discussed the concept of double standards; explaining that in Holland, former workers of the multinational corporation Eternit are compensated while in Belgium, they are not. As delegates entered the conference hall, they passed an exhibition of the work of South African photographer Hein du Plessis. His startling black and white photographs depict the impact of asbestos on people in South African towns that have been decimated by asbestos disease and pollution.
For decades, the British multinational, Cape Asbestos Co. A long-running legal action by 7, South African asbestos claimants has been dragging through the UK courts for years. Hein du Plessis explained his involvement with the case; his use of first person captions on the photographs was a deliberate attempt to give a voice to those no longer able to speak. Opening the exhibition, Dr. Sophia Kisting, who works with South Africans affected by asbestos, spoke eloquently of their dignity, expressing the hope that their struggle would not be forgotten.
During the first session on Wednesday morning, a panel of speakers addressed the situation relating to occupational asbestos exposure in Greece. Several salient facts were revealed during the presentations:.
Greece has the lowest rate of occupational disease in the European Union! Considering traditional working practices and the almost total absence of preventative measures, it is obvious that this statement does not accurately reflect the true incidence of occupational disease in Greece. Metoda Dodic-Fikfak from Slovenia said that although her country banned asbestos in , hundreds of people are still being occupationally exposed to asbestos; before , there were no asbestos claims from injured workers; since the national debate on asbestos began, the number of claims has grown; until there is a public debate on these issues, the problems will remain invisible;.
Many of the mesothelioma patients are retired, but there are a significant number of men in their 40s and 50s. The median survival rate for mesothelioma patients is 6 months. The earlier a diagnosis is made, the greater the chance that surgery could be considered.
This paper was presented by Dr. Gunnar Hillerdal from the Department of Lung Medicine at the Karolinksa Hospital in Stockholm and analyzed the risk to the general public.
Hillerdal said that because even low exposure can cause mesothelioma, it is important to continue phasing out asbestos in our surroundings: "Any source of asbestos releasing fibers in the environment should be identified and eliminated in a safe way.
Correct handling is essential in reconstruction or destruction of asbestos-containing buildings. Dodic-Fikfak and others who cited examples of pleural plaque patients with pain and breathing difficulties. The discussion on this topic continued in the medical workshop. A paper entitled The Global Use of Asbestos and Incidence of Mesothelioma showed the correlation between past asbestos consumption and the incidence of mesothelioma in industrialized nations.
Antti Tossavainen, from the Finnish Institute of Occupational Health, said: "The results of the research indicate that the national use of 2. While the disease rate could peak in Western countries around , Dr.
Tossavainen says "no reliable incidence data are available for the developing countries in Asia, Africa and South America. According to the United States Geological Survey, the processing of 64 tonnes of Greek ore was required per tonne of asbestos fiber produced.
During the s, average production at the Kozani chrysotile mine in Northern Greece was 70, tonnes a year; this means that over seven years, 32 million tonnes of ore were processed to produce , tonnes of asbestos. Given the long latency period of mesothelioma and the fact that production at the mine did not commence until the early s, the results of this exposure may not yet have become apparent.
Howie asked what steps have been taken to control fiber release from the mine tailings in Kozani? The younger the age at which someone is exposed to asbestos, the greater the risk that the disease will occur. Relative risk of developing mesothelioma by age 70 due to 5 year exposure starting at various ages. Unlike occupational asbestos exposure, the risk from environmental exposure is continuous; individuals may be exposed for 24 hours per day, days per year therefore "environmental fiber exposures must be stringently controlled to minimize risk.
Having taken us through the genesis of the EU asbestos ban, Mr. Vogel focused on recent developments. In September, , the Council of Ministers adopted a working text that revises aspects of EU asbestos regulations. Although the trade and import of asbestos and asbestos-containing products are banned within the EU all EU member states must comply by with the Directive which banned asbestos , there is ambiguity on whether the mining and export of asbestos from the EU to external countries is permitted.
The ETUC is pushing for clarification on this and other points such as the EU position on sending asbestos-contaminated ships to Asia for stripping, the sub-contracting of skilled asbestos removal work to unqualified companies, proposed revisions in the notification procedure which mean that whereas previously companies had to name the people who would be exposed before asbestos work began, now companies only need provide an estimate of the number of people likely to be exposed.
The speaker called for:. Due to unforeseen circumstances, the timetable was altered so that the next speaker was Dr. Sophia Kisting. In , the South African Government convened The Asbestos Summit in Johannesburg, bringing together a range of stakeholders including workers, trade unions, government officials, community groups, mining and asbestos companies.
While discussions at these meetings were productive, progress has been slow due to a lack of resources. The negotiated settlement reached in December, in the case brought by South African asbestos claimants against the British company, Cape plc had given hope to thousands of people in asbestos-contaminated communities. Four months after the money was due and ten months after the settlement had been agreed, no payment has been received leaving impoverished and ill workers in great difficulty.
The choice of topic by Asbestos Consultant Andy Oberta was particularly relevant to Greece - a country in which asbestos-cement products are still being manufactured. For nearly fifty years, amosite, crocidolite and chrysotile had been used at this site during the manufacture of asbestos-cement pipes and sheet products.
The factory owners distributed asbestos waste to local people for use on their driveways, paths and farms throughout western Galilee.
Although the plant shut in , friable and non-friable waste material was still lying on the beach and by the roads which bordered the factory site. A series of photographs illustrated the hazards of such a plan and Mr. Oberta explained the process by which negotiations with the Israeli Ministry of the Environment and local people resulted in the rejection of this idea. Vedsmand explained that although a Danish professor wrote a book about asbestos in , no one warned the insulation workers of the hazards for another twenty years.
An autopsy conducted in on an insulator who had worked with sprayed asbestos in the shipyards found asbestos in his lungs. By , a program had been set up to clinically examine insulators. The union campaigned for insulators to receive compensation for their asbestos injuries. There have been asbestos lawsuits in Denmark; one case against an asbestos-cement company went all the way to the Supreme Court.
The company was found liable for failing to inform the worker of the hazards of asbestos. Despite the fact that all forms of asbestos have been banned in Denmark for more than a decade, people are still dying and will continue to die from these diseases. To prevent more needless deaths, the union works with international groups such as the International Federation of Building and Woodworkers, which coordinates the efforts of trade unions with 11 million members in countries, and the International Confederation of Free Trade Unions to lobby for a global ban on asbestos.
Within Denmark, the union promotes awareness of the risks through its training courses. In Denmark, anyone whose work involves the risk of contact with asbestos is required to take a 4 day training course which covers information on the history and health risks of exposure to asbestos and practical guidelines on the recognition of asbestos-containing building materials and asbestos management techniques.
Subsequently, the Government of Buenos Aires began an asbestos removal project. Photographs from the first site visit to the jail show inspectors wearing ordinary street clothes; by the second visit, all the inspectors were in protective clothing and masks.
The photographs of the equipment and explanation of the procedures used in both places were informative.

For much of the 20th century, asbestos cement sheets provided builders with a rugged solution for simple roofing and siding projects. While these products were cheap to manufacture and buy, their true cost emerged years later in the form of deadly asbestos-related illnesses. Fibrous cement sheets are more durable than drywall and easier to work with than concrete, and they have numerous applications in construction. Today, the fibers in cement sheets are usually made of cellulose, a substance found in plants, but for the first eight decades after fibrous cement sheets were invented, they were primarily made with asbestos. Asbestos is a naturally occurring mineral that can be fluffed into a wooly consistency and mixed into building materials such as cement. Adding asbestos makes cement more durable, weatherproof and heat resistant, and because asbestos cement sheets are fireproof, builders initially considered them a much safer material than wood. Unfortunately, it is now well known that adding asbestos to cement also makes it highly toxic.

If you think you've found asbestos in your home, the first thing is: don't panic - but don't touch it. Asbestos in the home is a risk when it is disturbed in a way that produces fibres or dust containing asbestos fibres. This could include demolition work, renovating, drilling or doing work in or on roofs, around insulated pipes, and so on.
For the second year, the Russian economy has demonstrated an increase in export performance. According to the experts of REC, in , the volume of non-primary non-energy exports will amount to a record billion dollars against billion dollars last year and billion dollars in The growth of non-commodity non-energy exports is not accidental: Russian companies have adapted to new realities. As practice shows, with a responsible approach, negative news background and sanctions do not hinder development.
