MAP20071022385Heida, HenkOccupational exposure and indoor air quality monitoring in a composting facility / Henk Heida, Frans Bartman, Saskia C. van der ZeeSumario: The objective of this study was to investigate indoor air quality in a completely covered enclosure used for the aerobic composting of organic wastes originating from vegetable, fruit, and garden refuse. Samples of gases and vapors were taken in the ventilation exhaust ducts. Volatile organic compounds were collected on Tenax absorben; after thermal desorption they were analyzed by gas chromatography/mass spectrometry. Hydrogen sulfide was determined using Dräger test tubes. Microbial samplings were conducted on four sites inside the hallEn: American Industrial Hygiene Association journal. - Akron, Ohio. - Vol. 56, nº 1, January 1995 ; p. 39-431. Higiene industrial. 2.
