Airborne Asbestos Exposure from Gooch Fiber Use
نویسندگان
چکیده
Microscopical tests, including polarized light microscopy (PLM), phase contrast microscopy (PCM), scanning electron microscopy (SEM) and transmission electron microscopy (TEM) were used along with X-ray diffraction (XRD) in the characterization and testing of a laboratory-grade “Gooch fiber” asbestos sample. The sample was tested for possible fiber release during typical use as a substrate for gravimetric analysis methods. While preparing substrates, the concentrations of airborne asbestos fibers greater than 5 micrometers in length were approximately one fiber per cubic centimeter of air.

Background and aims : Asbestos minerals are divided into two main groups including serpentine and amphiboles and each has one or more subgroups. These minerals have been used in industrial products such as cement-asbestos sheet and pipe, brake shoe, clutch and insulation materials. Occupational and non - occupational exposures by this carcinogenic material have caused to develop several metho...

Occupational exposure to asbestos fiber of brake repair job (auto mechanics) has seldom been evaluated in Iran. Accordingly, we evaluated asbestos fiber concentrations in the breathing zone of auto mechanics between July 2008 and December 2008. The asbestos fiber concentrations of 60 personal air samples collected from 30 cars and trucks brake replacement and they were analyzed by phase-contras...

Introduction: Today, have been approved scientifically relationship between presence of asbestos fibers in the human respiratory area and malignant diseases such as lung advanced fibrosis (Asbestosis), gastrointestinal, lung and Laryngeal cancers. The aim of this study was the determination of asbestos fibers concentration in Yazd city’s air in the summer of 2015. Materials and Methods: ...
متن کاملAirborne asbestos exposures associated with the installation and removal of roofing products.
Asbestos-containing roofing products were widely used throughout the 20th century, and certain products are still used in limited quantities today. Roofing products are generally considered non-friable and are not expected to release appreciable amounts of airborne asbestos fibers; however, despite the variety of roofing products that have contained asbestos over time, there are no comprehensiv...
متن کاملAirborne asbestos and non-asbestos fiber concentrations in non-occupational environments in Korea.
Both airborne asbestos and non-asbestos fiber concentrations were evaluated in Korean non-occupational environments. The airborne fiber concentrations were analyzed in 96 air samples, from 48 different points, by transmission electron microscopy, with energy-dispersive X-ray analysis. The geometric means of the airborne asbestos and non-asbestos fiber concentrations were 0.62 and 67.86, and 0.3...
