Respirable crystalline silica: quartz i cristobalite Determinantion in workplace air with infrared spectrometry (FT-IR), direct on filters
Journal Title: Podstawy i Metody Oceny Środowiska Pracy - Year 2014, Vol 30, Issue 3
Abstract
A new procedure has been developed for the assay of respirable quartz and cristobalite with infrared spectrometry. Method is based on filtering the sample air through a filter of polyvinyl chloride (PVC), and direct determination of quartz and cristobalite in the dust deposited on the filter. The method enables the determination of the concentration of quartz in the range from 0,01 mg/m3 to 0,7 mg/m[sup]3 [/sup]and cristobalite in the range of 0,03 mg/m[sup]3[/sup] to 0,7 mg/m[sup]3[/sup] (in both cases, these values relate to air samples volume of 700 l). The developed method of determining quartz and cristobalite has been recorded as an analytical procedure, which is available in the Appendix.
