Monitoring and Evolution of the Pollution by Volatile Organic Compounds (Vocs) in the Groundwaters of The Najerilla River Basin (Spain)

摘要: VOCs were detected and identified in the water of several wells area Najera (La Rioja). The past uncontrolled spills from an important painting varnishing industry other smaller ones devoted to manufacture furniture activities sources plume this aquifer. This article shows results obtained monitoring assessment pollution at 18 sampling points for more than a year. It has allowed us study evolution different pollutants influence remediation process applied by company main source. analytical method is based on headspace-solid-phase microextraction (SPME) using 75-μm carboxen-polydimethylsiloxane fibre. Quantification was carried out gas chromatography with flame ionization detection. determine 13 polluted underground samples providing good sensitivity (LOD between 0.1 6.0 ng/mL) reproducib...
