THE STUDY OF THE BIOLOGICAL AGGRESSIVENESS OF DUST OF ASBESTOSFORMED AND ASBESTOS-FREE COMPOSITIONS, BOTH IN THEIR PRODUCTION AND OPERATION

This manuscript provides basic information on the use of asbestos. Some physicochemical properties of the main component of serpentine asbestos (SA, 95% of all used asbestos) and the biological aggressiveness of the following are considered: dust types in the technology of creating asbestos-containing products and during their operation. Attention is also paid to the use of existing asbestos substitutes in similar products. The authors present data verifying that the incidence of asbestos-related diseases, including asbestosis of a professional and unprofessional nature, is increased, especially in the elderly, in the places of production of an SA variety – chrysotile asbestos {CA, aqueous magnesium silicate - Mg6[Si4O10](OH)8}. The authors pay particular attention to the use of CA in the production of asbestos-formed parts/products (AFP), for example, brake linings containing CA and its substitutes. It is known that such products undergo significant zonal stresses during operation. CA fibers lose hygroscopic and constitutional water (H2O = 13.04 – 14.80%) in the process of car braking due to high pressure and increased local temperature. As a result, they almost entirely turn into a non-aggressive (in the biological sense) material called forsterite. Studies of brake dust emitted during the braking of lightweight VAZ vehicles did not reveal similar transformations of СA degradation. They may occur when braking heavy vehicles with a mass of more than 2.5 tons and when braking high-speed trains with a mass of more than 60 tons.

Occupational Burden of Asbestos-Related Diseases in Korea, 1998-2013: Asbestosis, Mesothelioma, Lung Cancer, Laryngeal Cancer, and Ovarian Cancer.

BackgroundAsbestos exposure causes asbestos-related diseases (ARDs) including asbestosis, malignant mesothelioma, lung cancer, laryngeal cancer, and ovarian cancer. Although Korea used substantial amounts of asbestos in the past, no study has focused on its occupational burden of disease (OBD). Therefore, this study aimed to determine the OBDs of ARDs in Korea.MethodsThe CARcinogen Exposure (CAREX) database was used to determine the proportion of exposed population. Relative risks for lung cancer, laryngeal cancer, and ovarian cancer were used to determine the population-attributable fraction. Data for deaths caused by ARDs during 1998–2013 were obtained from the World Health Organization mortality database. The potential years of life lost (PYLL) and annual average PYLL (APYLL) indicated OBDs.ResultsIn Korea, the number of ARD-attributable deaths and PYLL due to all ARDs during 1998–2013 were 4,492 and 71,763.7, respectively. The number of attributable deaths and PYLL due to asbestosis, malignant mesothelioma, lung cancer, laryngeal cancer, and ovarian cancer were 37 and 554.2, 808 and 15,877.0, 3,256 and 47,375.9, 120 and 1,605.5, and 271 and 6,331.1, respectively; additionally, the APYLL were 15.0, 19.7, 14.6, 13.4, and 23.4, respectively, and the average age at death was 70.4, 62.6, 69.1, 69.9, and 61.8, respectively. Our study showed that although the use of asbestos has ceased in Korea, the incidence of ARDs tends to increase.ConclusionTherefore, efforts to reduce future OBDs of ARDs, including early detection and proper management of ARDs, are needed in Korea.

The incidence of asbestos-related diseases about on asbestos enterprises in Qingdao from 1988 to 2014

It can provide statistics reference for the prevention and treatment by analysising the status and characteristics related to the asbestos disease of an asbestos products enterprises from 1988 to 2014. We have collected the data concerning the case of asbestos-related disease between 1988 and 2014, then the data were arranged, collecteted and analyzed using statistical method. The total of patients is 625 (male: 225, female: 400). Diagnosis of asbestosis is 617 cases, Accordingly, stage Ⅰis 500, stage Ⅱis 112 and stage Ⅲ is 5. Average age of morbidity is 64.84±9.87 and working age is 24.45±7.40 years; The patients of lung cancer caused by asbestos are 12 people, and average age of morbidity is 66.25±11.20 years, and the working age is 29.18±7.77years; The patients of mesothelioma are 4 people, average age of morbidity is 49-78 (M=60) and working age is 27years. Asbestosis patients with complications of pleural plaque is 37.44%, complications of pulmonary tuberculosis is 5.19%., and there are 239 patients lose their lives, motality is 38.74%. There is a high incidence of a disease about asbestos related disease in the asbestos products factory, it has close relationship with asbestos exposure time, the dust concentration of workplace and type of work et al. Asbestos related diseases are still the main problem in Qingdao.

Asbestos-related disease

Asbestos exposure used to be commonplace among manual workers in the UK. Although its import and use has been banned since the 1980s, the long latent period between exposure and onset of symptoms, means that the incidence of asbestos-related diseases has not yet peaked. The number of deaths attributable to asbestos exposure is expected to continue to rise for at least the next 5–10 years. For these reasons, knowledge of the various asbestos-related diseases is required by GPs. This article aims to describe the presenting features of these diseases and provides an outline of how they are usually managed in secondary care.

Preventive Measures to Eliminate Asbestos-Related Diseases in Singapore

The incidence of asbestos-related diseases (ARD) has increased in the last four decades. In view of the historical use of asbestos in Singapore since the country started banning it in phases in 1989 and the long latency of the disease, the incidence of ARD can be expected to increase further. As occupational exposure to asbestos still occurs, preventive measures to eliminate ARD continue to be required to protect the health of both workers and the public from asbestos exposure. The majority of occupational exposures to asbestos at present occur during the removal of old buildings. Preventive measures have been utilized by different government ministries and agencies in eliminating ARD in Singapore over the past 40 years. These measures have included the enforcement of legislation, substitution with safer materials, and engineering controls during asbestos removal as well as improvements in personal hygiene and the use of personal protective equipment. The existing Workman's Compensation System for ARD should be further refined, given that is currently stipulates that claims for asbestosis and malignant mesothelioma be made within 36 and 12 months after ceasing employment.

Prospective study of asbestos-related diseases incidence cases in primary health care in an area of Barcelona province

BackgroundAsbestos related diseases include a number of conditions due to inhalation of asbestos fibres at work, at home or in the environment, such as pleural mesothelioma, asbestosis and calcified pleural plaques. Few epidemiological studies have established the incidence of asbestos related diseases in our area. The present proposal is based on a retrospective study externally funded in 2005 that is currently taking place in the same area and largely carried out by the same research team.The aim of the study is to achieve a comprehensive and coordinated detection of all new cases of Asbestos Related Diseases presenting to primary care practitioners.Methods/designThis is a multicentre, multidisciplinary and pluri-institutional prospective study.Setting12 municipalities in the Barcelona province within the catchment area of the health facilities that participate in the study.SampleThis is a population based study, of all patients presenting with diseases caused by asbestos in the study area.MeasurementsA clinical and epidemiological questionnaire will be filled in by the trained researchers after interviewing the patients and examining their clinical reports.DiscussionData on the incidence of the different Asbestos Related Diseases in this area will be obtained and the most plausible exposure source and space-time-patient profile will be described. The study will also improve the standardization of patient management, the coordination between health care institutions and the development of preventive activities related with asbestos exposure and disease.

Asbestos-Related Diseases in a Population Near a Fibrous Cement Factory

Background and Objective The first fibrous cement factory in Spain was set up in Cerdanyola, Barcelona, in 1907 and was a source of pollution there until it was closed in 1997. The aim of this study was to determine the clinical and epidemiologic characteristics of the population with asbestos-related diseases who had worked in the factory and/or lived in the vicinity. Material and Methods We retrospectively collected information available on patients with asbestos-related diseases who at the time of diagnosis had resided in the area near the fibrous cement factory. Information was obtained from the medical records of the primary care centers of the 12 surrounding towns and the sole referral hospital in the area for cases diagnosed between January 1, 1970 and December 31, 2006. Results In the 559 patients diagnosed, 1107 cases of asbestos-related diseases were identified. Between 2000 and 2006, the average annual incidence was 9.5 cases per 100 000 inhabitants for the entire study area and 35.5 cases per 100 000 for the area nearest the factory. The prevalence of asbestos-related diseases as of December 31, 2006 was 91 cases per 100 000 inhabitants in the entire study area and 353.4 cases per 100 000 in the area nearest the factory. Of the 1107 asbestos-related disease cases identified, 86.5% were benign and 8.4% pleural mesothelioma. Conclusions The factory introduced an important area-wide risk factor for asbestos-related diseases for both workers and the nearby population. The number of cases detected annually showed an upward trend and the incidence of asbestos-related diseases was extremely high.

Non-occupational exposure to commercial amphibole asbestos and asbestos-related disease: is there a role for grunerite asbestos (amosite)?

An increase in the incidence of asbestos-related diseases in the general population from non-occupational exposure to the various asbestos fibre-types has been a concern since the identification of riebeckite asbestos (commonly referred to as blue asbestos or crocidolite in the medical literature) as an aetiological agent in human mesothelioma. Almost 40% of the mesotheliomas initially identified occurred near a mining operation in South Africa among individuals without an occupational history involving asbestos. As the various asbestos fibre-types shared a common commercial name the initial expectation was that the carcinogenic potency of all the asbestos fibre-types would be similar, if not identical. Urgency was added to these concerns as asbestos-related pleural changes were found elsewhere in the general population in certain geological locales and low concentrations of asbestos bodies began to be found with frequency in the lungs of the general population in a number of urban centres. The seminal studies since 1960 are reviewed to illustrate the potential for the commercial amphibole asbestos minerals to produce disease among individuals with non-occupational exposure, with particular attention to grunerite asbestos.
