Título Evaluation of public and worker exposure due to naturally occurring asbestos in gravel discovered during a road construction project
Información bibliográfica Sep. 2008, Vol.5, No.9, p.609-616. 20 ref.
Resumen During a road repair project in a remote region of Alaska, it was discovered that the materials used from a local material site contained asbestos. Evaluation of asbestos exposure to workers was required, as was the possible future exposure of workers and the general public. In addition, a decision was needed on whether to use materials from the contaminated site in the future. Of the almost 700 breathing zone air monitoring samples taken of the workers, 3% of the samples indicated exposures at or near 0.1 fibre/cc by phase contrast microscopy. Further analysis of 36 samples by transmission electron microscopy indicated that about 40% of the fibres were asbestos. Implications of these findings are discussed.
