Benzene, toluene, ethylbenzene, and isomeric xylenes in various water samples in Croatia
In this study, headspace solid-phase microextraction (HS-SPME), a variation of static headspace sampling, followed by gas chromatography/mass spectrometry has been applied to the analysis of benzene, toluene, ethylbenzene, and isomeric xylenes (BTEX) in river, marine, municipal, thermal, well and lake water samples collected in different areas of Croatia. The most frequently measured compound in this study (33 water samples) was m/p-xylene (in 100 % of samples analyzed), followed by toluene (94 %), and ethylbenzene (73 %). Benzene was found in only three samples (9 %), and o-xylene in only one sample (3 %). In most samples the BTEX concentrations were lower than 800 ng/L. The exception was toluene whith concentrations of 1.073 microgram/L in one municipal water and 41.736 microgram/L in one thermal water close to the oil-wells. In most of the samples analyzed in this work BTEX were in similar and low concentrations not representing a risk for environmental pollution.
