Title = Comparison
of Volatile Organic Compounds from Processed Paper and Toners from Office
Copiers and Printers: Methods, Emission Rates, and Modeled Concentrations |
Abstract = The
emission of volatile organic compounds (VOC) from nine toner powders and
eleven types of processed paper from photocopying machines (6), laser (3)
and matrix printers (2), and one carbonless copy form has been measured.
A total of 61 VOC from toner powders were identified by heating (185 C)
the powder for three minutes for thermal desorption and by gas chromatography
followed by the use of low and high resolution EI and CI mass spectrometry.
VOC from processed paper were analyzed by headspace sampling on Tenax TA
from nylon bags. Thirty-one VOC with a wide range of volatility and persistency
were identified from processed paper. The total VOC emission from the various
types of paper differed substantially. Using the field and laboratory emission
cell (FLEC), the calculated initial emission rate of styrene was 5 ug m-2h-1
from a freshly processed paper. The VOC emission from machines and the
processed paper can be reduced by proper choice of office equipment. However,
an evaluation should consider all potential pollutants. |
