Abstract

|
|
This study was performed to confirm an analytical method for polyunclear aromatic hydrocarbons (PAHs) in metalworking fluids(MWFs) which were used in metalworking factories. To ensure the analysis with accuracy and precision the fesults of PAHs in MMFs, this study was tried to use solid phase extraction(SPE) and gas chromatography/mass selective detector(GC/MSD). Also, this study was examined the concentrations of PAHs in MMF bulks and the qualitative analysis polycyclic aromatic compounds(PACs)excluding PAHs.
21 bulk samples were sampled in 7 metalworking factories. 21 bulk samples were 18 cutting oil(13 straight oils and 5 soluble oils) and 3 others(lubricating oil, discharge oil. compresses oil). 6 SPE cartridges were used to analyze PAH in MMFs and GC/MSD(satum 2000, Varian, U.S.A). Among the the 6 SPE cartridgesm this study was selected strong cation exchanger(SCX, aromatic benzene sulfonic acid functional group) cartridge for PAHs extraction in MMFs. Also the recovery test was performed.
1. The appropriated cartridge of SPE for analysis of PAHs in MWFs was found to be SCX.
2. The detected PAHs in MWFs were naphthalene(n=2). acenaphthylene(n=1). phenanthree(n=1), anthracene(n=2), fluoranthene(=7), pyrene(n=11) benzo[b]fluoranthene(n=1), chrysene(n=1), benzo[k]fluoranthene(n=1), benzo[k]fluoranthene(n=1).benzo[a]pyrene(n=1), dibenz[a,h]anthracene(n=2) and benzo[ghi] perylene(n=8). Total PAH(n=12) concentrations range were lower than LOD-270.03ug/ml.
3. The component of the PACs excluding PAHs were naphthalenes, acenaphthenes, chrysenes, anthracenes, indenes, fluoranthenes, fluorenes, pyrenes, benzopyrenes, phenantherenes and others volitile organic compounds(VOCs)were amines, phenols, aldehydes and others.
For the results, SCX cartridge was better than other 5 SPE cartridges. 13 of 16 PAHs components were detected in MWFs. However recovry rate in this study should be improved analytical techniques on PAHs in MWFs. Also this study was need for further investigation for more MWFs samples and environmental monitoring and evaluation of MWFs exposed workers.
