Deadly Asbestos Taking Toll Years After Kids Exposed

“Wittenoom kids” who spent their childhoods exposed to asbestos in the north-west of Western Australia, are now developing a range of cancers or dying at a rate well above the average population, according to a new study by the Western Australian Institute for Medical Research (WAIMR).
Mining of the deadly blue asbestos at Wittenoom, 1106km north of Perth, ceased in 1966 and the town was later closed after airborne fibres in dust from mining operations were found to cause malignant mesothelioma, lung cancer, asbestosis and other serious diseases.
While data has been collected previously looking at asbestos related diseases caused by occupational asbestos exposure among men (either working in asbestos mining towns or using asbestos products), this new study is the first to look at the long term health of children who were exposed to asbestos at Wittenoom.
The study, which has been published in the American Journal of Industrial Medicine, shows that girls up to the age of 15, who lived in Wittenoom, have been more likely to develop mesothelioma, ovarian and brain cancers and have had increased death rates.
Boys who spent their childhood and early teenage years in Wittenoom during the years that asbestos was mined (1943-1966) now have elevated rates of mesothelioma, leukaemia, prostate, brain and colorectal cancer, diseases of the circulatory and nervous system and excessive death rates.
“The original township was only 1.6 kilometres from the mine,” said leading researcher on the paper, WAIMR’s Associate Professor Alison Reid. “Later, in 1947, when the population grew, the township was moved 12 kilometres away from the mine site but tailings from the mine were used throughout the town.
“These tailings, rich in crocidolite fibres, were used to pave roads, footpaths, parking areas, the local racecourse and school playgrounds. They were even used in people’s backyards, where, of course, children often played.” she said. “These “Wittenoom kids” are now reaching the age where chronic adult diseases are becoming more prevalent and many have died.”
Associate Professor Reid said the study by WAIMR researchers with the University of Western Australia’s School of Population Health, found that a total of 2,460 former Wittenoom children were documented to have been exposed to blue asbestos before the age of 15.
The median age of their first exposure was at 3 years of age.
Of the people studied, 63% were either born in Wittenoom or had moved to the mining town by the time they were 5 years old. The vast majority (93.5%) left Wittenoom by the time they were 16, so were only exposed to asbestos during their childhoods.
To the end of 2007, 228 of the former residents had died of a range of causes and to the end of 2009 there were 215 cases of cancer in 207 individuals.
This means that compared with the general population in Western Australia, Wittenoom girls have had a 20-47% greater risk of dying from any cause, while boys have had a 50-83% increased chance of dying from any cause.
“We will continue to follow this group to provide important information on the long-term implications of exposure to asbestos during childhood,” said Associate Professor Alison Reid.
The attached sandpit photo from 1953 shows four year old neighbours playing in an asbestos sandpit in a residential backyard in Wittenoom. Residents purchased the deadly tailings which were commonly used as sandpits in backyards for the purposes of children’s play and also to reduce dust around houses.
