چکیده
Adsorbent tube samples are collected by drawing workplace air through either coconut shell charcoal or Anasorb 747 tubes with personal sampling pumps. Diffusive samples are collected by exposing either 3M 3520 Organic Vapor Monitors (OVMs) or SKC 575-002 Passive Samplers to workplace air. Samples are desorbed with 60/40 (v/v) N,N-dimethylformamide/carbon disulfide (DMF/CS2) and analyzed by gas chromatography using a flame ionization detector.

Exposure assessment of ETBE in gas station workers and gasoline tanker truck drivers.
OBJECTIVES In order to measure occupational exposure concentrations of ethyl tertiary-butyl ether (ETBE), we developed a diffusive sampling method for monitoring ETBE and performed an ETBE exposure assessment. METHODS The applicability of diffusive samplers was examined by exposing the samplers to ETBE vapor in test chambers. The personal exposure levels of workers and airborne concentrations...
متن کاملValidation of diffusive mini-samplers for aldehyde and VOC and its feasibility for measuring the exposure levels of elementary school children.
Exposure to various chemicals can cause adverse effects to health, such as asthma and allergies, especially in children. Data on personal exposure levels in children are scarce, thus small lightweight diffusive mini-samplers for aldehydes and volatile organic compounds (VOCs) were designed to measure the exposure level of children to these chemicals. The aim of the study was to validate and exa...
متن کاملPerformance of High Flow Rate Samplers for Respirable Particle Collection
The American Conference of Governmental Industrial hygienists (ACGIH) lowered the threshold limit value (TLV) for respirable crystalline silica (RCS) exposure from 0.05 to 0.025 mg m(-3) in 2006. For a working environment with an airborne dust concentration near this lowered TLV, the sample collected with current standard respirable aerosol samplers might not provide enough RCS for quantitative...
متن کاملMeasurement of 2,4-toluene diisocyanate concentrations by different samplers.
The standard sampling methods for toluene diisocyanate (TDI) only collect total TDI without separating the aerosol and gas phases. There are few other samplers, such as the dual filter, triple filter and annular denuder systems (ADS), which are able to sample the aerosol and gas phases simultaneously. This field study was conducted at two workplaces to access the total 2,4-TDI and the gaseous a...
متن کاملApplication of passive sampling technique for monitoring of BTEX concentration in urban air: field comparison of different types of passive samplers.
Urban air background concentrations of benzene, toluene, ethylbenzene, and xylenes (BTEX) were measured in 2007 in the Tricity area (Gdansk, Gdynia, and Sopot) and Tczew applying two types of passive samplers: Home-made permeation passive samplers and two diffusive passive samplers Orsa 5 (National Dräger) and Radiello (FS Maugeri). Differences between the time-weighted annual averages concentr...
