چکیده

During the past 20 years there has been increasing concern about the long-term effects of occupational exposure to a wide range of substances. Different techniques have been developed to assist in the retrospective study of whole populations exposed to such hazards. Doll (1952) used a gas company's pension records to identify an occupational risk of lung cancer; he also (Doll, 1955) used the personnel records of an asbestos factory to identify the risk of lung cancer among its male workers. Case and Bidstrup (1956) measured the mortality rate of 723 chromate workers who had been clinically surveyed. Case, Hosker, Macdonald, and Pearson (1954) obtained nominal rolls of workers employed in 21 firms in the dyestuffs industry and used hospital records and death registers to establish the incidence of bladder tumour. In the United States, Mancuso (1959) and Mancuso and Coulter (1963) have used a method of tracing an industrial population which is quite independent of local factory records. The Bureau ofOld Age and Survivors Insurance (BOASI), a department of the Federal Government, keeps records of nearly all employed persons in order to administer social security benefits. The record of the worker can be related to the employer. By using BOASI records they obtained data relating to those employed at a certain asbestos factory in 1938 and 1939 and studied the mortality of these cohorts. In this paper it will be shown how the national registers and local records can assist in tracing the fate of past employees at an asbestos factory. It is hoped to determine the mortality rates from various diseases and study the influence of length of exposure, of exposure to different types of asbestos, and of different jobs. The techniques used can be applied in tracing any industrial population.

Asbestos Presence in a Factory that Produced Asbestos-Containing Products

In 2007, research was carried out to determine the type and amount of asbestos fibers in a Croatian factory with a long history of making asbestos-containing products.Since the 1970s, asbestos fibres have been considered carcinogenic in humans i.e as a known cancer-causing agent. In the environment, asbestos fibres are inactive and naturally resist biodegradation. In time, fibres can only be gr...

Mortality among long-term employees of an Ontario asbestos-cement factory.

Mortality was studied among a group of 328 employees of an Ontario asbestos-cement factory who had been hired before 1960 and who had been employed for a minimum of nine years. The group of 87 men who had worked in the rock wool/fibre glass operations, or who had been otherwise minimally exposed to asbestos, had mortality rates similar to those of the general Ontario population, while the group...

Environmental history of a factory producing friction material.

The fibre concentrations generated during the production of friction materials, incorporating asbestos, over the past 60 years have been studied to provide cumulative dust exposure data for a mortality study of the work-force. Chrysotile has been used almost exclusively during this period. The measurements made routinely by the factory staff provided information from 1950 onwards; concentration...

Mesotheliomas and asbestos type in asbestos textile workers: a study of lung contents.

The asbestos contents of the lungs of former employees of an asbestos textile factory were determined at necropsy using a transmission electron microscope. Those who had died of mesothelioma were compared with a matched sample of those who had died of other causes. The predominant fibre processed in the factory was chrysotile, but crocidolite had also been used. The lung content was consistent ...
