Determining pollution level of a medium without wasting tools, time or solvents possible
Date:7/8/2011

d large molecule interference is avoided.

After extraction desorption should be proceeded with, in order to free the gases absorbed by the fibre and thus separate the substances. Mr Zuazagoitia opted for gas chromatography, by which the components can be separated with notable volatility at temperatures less than 350-400 degrees. Subsequently, the components were quantified using an FID ionisation detector.

Optimisation of three procedures

For his thesis Mr Zuazagoitia developed methods which, based on HS-SPME, determined various small and medium molecular weight PAHs simultaneously, considering the diversity of conditions that these methods have to comply with, depending on the matrix to analyse (water, earth, sediments, and so on). Likewise, given the numerous variables that condition the process, an experimental design that optimised the response of the method was opted for. Using the Statistica programme, it is not necessary to carry out trials with each variable in order to ascertain their ups and downs beforehand.

Mr Zuazagoitia stated that, effectively, there exist rapid and simple methods and that can be undertaken with any laboratory analytical tools. Other characteristics of these methods involve having a rapid response (positive/negative) objective and being environmentally friendly, on not using organic solvents. The three procedures optimised in the thesis (water, earth, sediments) comply with these features.

In San Sebastin, Bergara and Pasaia

The researcher also took on the task of putting into practice methods for studying the pollution of water, earth and sediments in Gipuzkoa. According to the samples analysed, the concentrations of PAHs in the sea and river water in the territory are not relevant. However, there is a high level of contamination in leached waters, meaning that there is a high concentration of PAHs in soil these originate from. With the soil samples, Mr Zuazagoit
