  1. Respiratory health effects of opencast coalmining : a cross sectional study of current workers.

    Article - En anglais

    Objectives-To identify whether there is evidence of pneumoconiosis and other respiratory health effects associated with exposure to respirable mixed dust and quartz in United Kingdom opencast coalmines.

    Methods-A cross sectional study of current workers (1224 men, 25 women) was carried out at nine large and medium sized opencast sites in England, Scotland, and Wales.

    To characterise a range of occupational groups within the industry, full shift measurements of personal exposures to respirable dust and quartz were taken.

    Up to three surveys were carried out at each site, covering all four seasons.

    For the purposes of comparisons with health indices these groups were further condensed into five broad combined occupational groups.

    Full sized chest radiographs, respiratory symptoms, occupational history questionnaires, and simple spirometry were used to characterise the respiratory health of the workforce.

    Logistic or multiple regression techniques were used to examine relations between indices of exposure and respiratory health.

    ResultNone of the group geometric mean dust concentrations, based on 626 valid dust samples, exceeded 1 mg. m-3, and 99% of all quartz concentrations were below 0.4 mg. m-3, the current maximum exposure limit.

    The highest quartz concentrations were experienced by the rock drilling team and drivers of bulldozers (used to move earth and stone from layers of coal). (...)
