  • Mesothelioma Due to Neighborhood Asbestos Exposure: A Large-Scale, Ongoing Disaster Among Residents Living Near a Former Kubota Plant in Amagasaki, Japan
    Asbestos Disaster, 2020
    Co-Authors: Norio Kurumatani, Shinji Kumagai

    Abstract:

    We describe a serious on-going outbreak of Asbestos disasters which were uncovered in Japan in 2005 (the Kubota Shock). According to our epidemiological study, around 100 residential mesothelioma cases have been attributed to a single Asbestos Cement Pipe plant. That plant, now closed, was located in Amagasaki City, Hyogo Prefecture, west of Osaka. It was run by the Kubota Corporation, currently a large machinery company world-wide. A significantly increased risk of developing mesothelioma occurred among residents in the area which extends 2 200 m south south-east and 900 m north north-west from the center of the plant. This is in accordance with the predominant wind direction in the area, which blows from the north north-west. New cases of mesothelioma have continued to arise among residents, with the total number of mesothelioma patients currently near 200. Asbestos has been widely used since the early twentieth century, and therefore many factories world-wide, some of which are now closed, have handled Asbestos and Asbestos-containing products and may have spread Asbestos into the surrounding communities. Mesothelioma develops more than 40 or 50 years after the first Asbestos exposure. Public health policy-makers, health professionals, and industry need to recognize the serious health risks associated with the wide areas of neighborhood Asbestos exposure in the present and in the future.

  • mapping the risk of mesothelioma due to neighborhood Asbestos exposure
    American Journal of Respiratory and Critical Care Medicine, 2008
    Co-Authors: Norio Kurumatani, Shinji Kumagai

    Abstract:

    Rationale: Little is known about neighborhood exposure to Asbestos and mesothelioma risk among residents around an industrial source of Asbestos.Objectives: To investigate the magnitude of the risk among residents by Asbestos exposure levels and to determine the range of the area affected by Asbestos.Methods: We calculated standardized mortality ratios of mesothelioma from 1995 to 2006 among the estimated population at risk that lived around a former large Asbestos Cement Pipe plant in Amagasaki City, Japan, between 1957 and 1975, the time when the plant had used crocidolite and chrysotile. The distance between the plant and homes and relative Asbestos concentrations obtained by diffusion equations involving meteorological conditions were used to determine Asbestos exposure levels among residents.Measurements and Main Results: We identified 73 mesothelioma deaths of 35 men and 38 women who had no occupational exposure to Asbestos. Among persons who had lived within a 300-m radius of the plant, the standar…

  • tetrachloroethylene leached from lined Asbestos Cement Pipe into drinking water with discussion
    , 2016
    Co-Authors: Charles D Larson

    Abstract:

    Tetrachloroethylene has been detected in concentrations ranging from a few micrograms per litre to several milligrams per litre in dead ends of water distribution systems made of vinyl-toluene-lined AsbestosCement Pipe. About 1600 km (1000 mi) of this lined Pipe is being used, primarily in New England. Tetrachloroethylene concentrations can be lessened by flushing and installing continuous bleeders, two of the solutions being suggested to correct this organics problem, which resulted from steps to control corrosion of AsbestosCement Pipe.
