When setting method, it was recommended that four times of gas volume exchange could be set as the start of sampling. After analyzing 26 water and air samples from wastewater treatment units, acetone and toluene were found at high concentrations in most samples. Depending on the characteristics of processing, benzene, 2-butanone, ethyl benzene and styrene can be also presented at high concentrations. After checking with raw materials used in processes, there is a high correlation between raw materials and the detected chemicals. However, the concentrations of air samples are not consistent with those of water samples.
Another testing of 29 volatile organic compounds from duplicate samples showed that the percentages of difference between duplicate analyses were from 0.0% to 195.0%. The difference of duplicate analysis was not quite well, and it might be ascribed to the heterogeneity of water samples from the continuous-flow units.
Air samples were sampled and analyzed by NIEA A722.74B, NIEA A701.11C and NIEA A715.14B methods. The results showed that the percentages of difference between duplicate analyses, checking recovery were complying with the quality specifications of each method.
The testing of 1,3 - butadiene was completed by using NIEA W785.54B method Measurement of volatile organic compounds in water by purge and trap coupled with Capillary Column Gas Chromatography / Mass Spectrometry . The results of duplicate analysis, checking recovery and adding standard recovery were complying with the QA/QC requirements of NIEA W785.54B method. Therefore, NIEA W785.54B method can be applied to the analysis of 1,3-butadiene.
