Armley asbestos disaster
The contamination was the result of the activities of a local asbestos factory, part of the Turner & Newall (T&N) group (often referred to by the name of its founders, J. W. Roberts Ltd.) and occurred between the end of the 19th century and 1959 when the factory eventually closed. At its peak the factory had 250 employees. At least 300 former employees are believed to have died from asbestos-related illnesses, and a number of cancer deaths in the Armley area were traced to the factory in 1988 as a result of an investigation by the "Yorkshire Evening Post". The estate was found to have the highest incidence in the country of mesothelioma. As the interval between exposure and diagnosis can be up to 50 years the number of further deaths which may occur due to the factory's emissions or residual dust since its closure cannot be predicted.
Arley, Warwickshire
The village once had an eponymous colliery running beneath part of its central area which employed 1,734 men when it was finally closed on 30 March 1968, by the National Coal Board. It had then been in operation for sixty six years and had once been owned and operated by the Arley Colliery Company Ltd. Production began at the pit on 1 January 1901 and the first coal was extracted from the mine in 1902. The mine was considered no longer economically viable by the NCB led by Lord Robens, officially of the Labour Party, in 1968, due to its relatively high costs and despite the cited fact that one hundred years of coal remained beneath. As production increased the colliery expanded and with this the population within the parish increased. This led to a need for new housing in the area. Between 1920 and 1955 six hundred houses were built on land which had been the Fir Tree Farm, this became New Arley.
