Use of passive SPME sampling devices to determine exposure of oil painters to organic compounds

Abstract

A solid-phase microextraction (SPME) sampling device, called a needle trap samplers (NTS) that were packed with 60-80 mesh divinylbenzene (DVB) particles, was used to extract indoor volatile organic compounds (VOCs) that were emitted in an oil painting studio. This work compared the sampling performances of a passive NTS and an active charcoal desorption tube that was connected to a personal sampling pump (Method 1501), developed by the National Institute of Occupational Safety and Health, USA. The experimental results reveal that the NTS is a dependable alternative device to Method 1501 for monitoring indoor air quality. 2,2,4,6,6-Pentamethylheptane (isododecane) is the main emitted pollutant when oil painters use odorless thinner as a substitute solvent for turpentine oil, and the mean exposed concentrations of isododecane determined by NTS ranged from 0.83 to 3.10 ppm, which were dependent on whether the indoor ventilation was performed by the natural or mechanic mode. To maintain adequate air exchange rates in an oil painting studio, doors should be opened to increase air circulation, lowering the concentrations of isododecane to which painters are exposed.Implications: A needle trap sampler (NTS) was used to sample VOCs from oil painting in an indoor studio. Isododecane is the main emitted pollutant when painters use the odorless thinner. The NTS was evaluated to be a dependable alternative to Method 1501 for monitoring indoor air quality. To maintain adequate air exchange rates in a painting studio, doors should be opened to lower concentrations of VOCs.

Research on Oil Painting Layout and Expression Form Based on Multi Data Visual Communication

“…It is present process modifications in the new form, is being affected via many new media, and is additionally growing different new styles. Oil portray advent has determined a new improvement space, and it will coexist with different visible media for a lengthy time; it enriches our visible world together [14].…”

Recent progress in wearable extractive sampling technology

“…The TWA concentration of xylene after 8 h sampling with NTs showed a good agreement with the standard active sampling method (NIOSH 1501), highlighting the advantages of this device for routine exposure studies. The same type of NT device was also investigated for monitoring the exposure of oil painters to organic compounds such as isododecane, which is the main emitted compound from the oil thinners [53]. The obtained results from passive NTs and NIOSH 1501 active sampling generally agreed with slightly higher concentrations obtained by NTs, which was explained by the better efficiency for the extraction with NTs.…”
