Asbestos history and use.

All six fiber types called asbestos can cause all the diseases related to exposure, including lung cancer. Known to the ancients, the modern history of asbestos hazards started in the 1890s with more and more data accumulating over time. Use increased exponentially in the middle of the 20th century with major use coming in construction and ship building. The recognition of asbestos as causing lung cancer dates to the early 1940s.

[The Amiantus Program in Poland - 20 years of implementation]. / Program Amiantus w Polsce ­ 20 lat realizacji.

BACKGROUND: Despite the ban on the production of asbestos-containing materials, introduced in Poland over 20 years ago, new cases of asbestos-related diseases are still being recorded. Systematic control of respiratory function in people exposed to asbestos dust is, therefore, extremely important due to the biological properties of this mineral. MATERIAL AND METHODS: The Amiantus preventive medical examination program was undertaken in 2000 to implement the legal rights of former employees of asbestos processing plants for this type of examinations. People who have ever been employed in such factories have been authorized to use preventive medical examinations for the rest of their lives. The research is continuous, spread over time and focused, in particular, on the assessment of the respiratory system. RESULTS: Since the beginning of the program, throughout 20 years of its implementation, 8329 people have been examined, including 5199 (62.4%) men for whom a total of 34 454 medical examinations have been carried out. During the program period, the percentage of diagnosed pathologies increased from 8% in 2000 to 25% in 2019. Overall, 2078 asbestos-related diseases were diagnosed among former employees of asbestos processing plants under the Amiantus Program, which accounted for 25% of this group. Among all diseases caused by exposure to asbestos, the most common were: asbestosis (1880 cases - 90.5%), lung cancer (121 cases - 5.8%) and pleural mesothelioma (77 cases - 3.7%). Diseases of pleura in the form of plaques and diffuse pleural thickening were diagnosed in 40% of the examined patients, while radiological pulmonary shadows affected over 65% of former employees of asbestos processing plants. CONCLUSIONS: The Amiantus Program, thanks to the long observation period, enabled monitoring the health of former employees exposed to asbestos, and created a unique opportunity to carry out epidemiological analyzes. These studies allowed the authors to expand their knowledge of the natural history of asbestos-related diseases. Med Pr. 2020;71(5):595-601.

Jock McCulloch (1945-2018): A Tribute.

Jock William McCulloch, who died at Melbourne, Australia, in January 2018, was one of the foremost historians of occupational health of his generation. This tribute reviews his career and oeuvre, which was tragically ended by his death from mesothelioma.

Experimental asbestos studies in the UK: 1912-1950.

The asbestos industry originated in the UK in the 1870s. By 1898, asbestos had many applications and was reported to be one of the four leading causes of severe occupational disease. In 1912, the UK government sponsored an experimental study that reported that exposure to asbestos produced no more than a modicum of pulmonary fibrosis in guinea pigs. In the 1930s, the newly established Medical Research Council, with assistance from industry, sponsored a study of the effects of exposing animals to asbestos by injection (intratracheal and subcutaneous) and by inhalation in the factory environment. Government reports, publications, and contemporary records obtained by legal discovery have been reviewed in the context of the stage of scientific development and the history of the times. Experimenters were engaged in a learning process during the 1912-1950 period, and their reports of the effects of asbestos were inconsistent. Pathologists who studied the effects of asbestos experimentally, at whole animal, tissue and cellular levels, advanced experimental methodology and mechanistic knowledge. In the hands of public relations experts, however, research was exploited to preserve an industry and perpetuate preventable diseases, a practice that continues to this day.

Clarence Borel.

Borel v. Fibreboard Paper Products Corporation is the 1973 landmark case that paved the way for successful litigation against the asbestos industry. Clarence Borel's granddaughter shares recollections of the reluctant man behind the court case.

[Asbestos at the time of the First World War]. / [L'amianto al tempo della Grande Guerra].

Between the end of the 19th century and the beginning of the 20th numerous asbestos industries began operations in various parts of the world. At the time of the First World War there is ample evidence of the use of this mineral in shipbuilding, the aircraft industry and in the construction industry. In the years 1912-17 the writer Franz Kafka was co-proprietor of a small asbestos factory in Prague. Some of the writer's novels and journal pages were inspired by this experience. In this way asbestos entered into the history of 20th century European literature. In 1917 asbestos extraction was started at the quarry in Balangero, near Turin, Italy. Risks related to the use of asbestos were known at the beginning of the 20th century and legislation aimed at preventing the harmful effects of the mineral were approved in Italy.

On Corporate Accountability: Lead, Asbestos, and Fossil Fuel Lawsuits.

This paper examines the use of lawsuits against three industries that were eventually found to be selling products damaging to human heath and the environment: lead paint, asbestos, and fossil fuels. These industries are similar in that some companies tried to hide or distort information showing their products were harmful. Common law claims were eventually filed to hold the corporations accountable and compensate the injured. This paper considers the important role the lawsuits played in helping establish some accountability for the industries while also noting the limitations of the lawsuits. It will be argued that the lawsuits helped create pressure for government regulation of the industries' products but were less successful at securing compensation for the injured. Thus, the common law claims strengthened and supported administrative regulation and the adoption of industry alternatives more than they provided a means of legal redress.

Malignant pleural mesothelioma: history, controversy and future of a manmade epidemic.

Asbestos is the term for a family of naturally occurring minerals that have been used on a small scale since ancient times. Industrialisation demanded increased mining and refining in the 20th century, and in 1960, Wagner, Sleggs and Marchand from South Africa linked asbestos to mesothelioma, paving the way to the current knowledge of the aetiology, epidemiology and biology of malignant pleural mesothelioma. Pleural mesothelioma is one of the most lethal cancers, with increasing incidence worldwide. This review will give some snapshots of the history of pleural mesothelioma discovery, and the body of epidemiological and biological research, including some of the controversies and unresolved questions. Translational research is currently unravelling novel circulating biomarkers for earlier diagnosis and novel treatment targets. Current breakthrough discoveries of clinically promising noninvasive biomarkers, such as the 13-protein signature, microRNAs and the BAP1 mesothelioma/cancer syndrome, are highlighted. The asbestos history is a lesson to not be repeated, but here we also review recent in vivo and in vitro studies showing that manmade carbon nanofibres could pose a similar danger to human health. This should be taken seriously by regulatory bodies to ensure thorough testing of novel materials before release in the society.

[Asbestos in pre-industrial times: from natural wonder to subject of scientific investigation]. / L'amianto in epoca preindustriale: da meraviglia della natura ad oggetto di approfondimento scientifico.

The author proposes a reading of "Concerning incombustible flax or asbestos stone" which was published in 1696 by Giovanni Giustino Ciampini, who was a historian, a man of the church and scientist in Rome. The text, which was originally written in Latin, is an excellent and early description of the need felt by the majority of scientists in Europe at that time for a change in method: that is, to use scientific experiments to explain and control the natural phenomena observed and even perhaps mythologized right from antiquity. In the case of asbestos this was necessary to check the veracity and consistency of a series of recommendations handed down by the earliest authors but also to revive and reinvent the techniques that had largely been lost so as to be able to utilize and develop a substance that it was thought could be of great benefit to society. In the presentation of Ciampini's text an attempt is made to recall and contextualize the earliest knowledge on asbestos and follow its evolution over a long historical period, up to the first half of the nineteenth century. It can thus be seen how asbestos, once considered "a wonder of nature", became a raw material widely used in industrial applications. The most significant steps in this phase of transformation were taken thanks to Italian entrepreneurs and technicians and to the presence of asbestos in the Alpine valleys of Italy.

Perceiving a dust hazard in ordinary conditions of work.

Twenty years before the ill-effects of exposure to asbestos dust became an issue of public concern in Victoria, medical knowledge about this occupational hazard and its management were readily available in the Industrial Hygiene Division of the Victorian Department of Health. The failure of the State Electricity Commission to incorporate this body of knowledge into the management of its power stations cannot be attributed to a callous disregard for workers' health. It was rather that the organisational structure and ethos of this semi-autonomous government agency, dominated by engineering expertise, fostered an intolerance of the expertise of other professionals-in this case, that of medical practitioners specialising in industrial hygiene. The events recounted in this paper illustrate the extent to which the perception of an occupational hazard in 'ordinary conditions' of work can be obstructed by the everyday circumstances of an organisation's operation.

A camel through the eye of a needle: expertise and the late recognition of asbestos-related diseases.

The aim of this study is to provide new insights into the late recognition of asbestos-related diseases in contemporary societies. It addresses the role of expert culture in the identification, management, and control of asbestos risks, and examines the contribution of these processes to the late recognition and minimization of risks. After focusing first on Spain, the article presents three historical case studies to illustrate some shortcomings of the expert explanatory model. First, the narrow definition of asbestosis forged by medical experts in interwar Britain helped shape a public perception of the asbestos issue as finite and controllable. Second, the alternative approach to asbestos hazard management proposed by the Spanish trade union Comisiones Obreras in the early 1980s, inspired by the so-called Italian workers' model, prioritized locally produced knowledge. Finally, in the changing public view of asbestos risks in France during the last third of the 20th century, cultural and social factors played a crucial role in broadening the issue beyond its conception as just an occupational health problem. The author argues that expertise itself becomes a deproblematizing agent for industrial health issues, paving the way for their social invisibility.
