Comparison of different methods for extraction of polycyclic aromatic hydrocarbons (PAHs) from Sicilian (Italy) coastal area sediments.

2012

This paper describes a work aimed at improving the conditions of an extraction method, coupling GC-MS determination, for the analysis without cleanup phase, of polycyclic aromatic hydrocarbons (PAHs) from sediment samples. The automatic Soxhlet extraction in warm mode (using Extraction System B-811 Standard, Buchi) has demonstrated advantages for automation, reduced extraction time, and lower solvent use than for conventional Soxhlet extraction. Under these conditions, the recoveries are very good as they resulted greater than 85 % and, in most of the cases, near 100 %. The repeatability is also satisfactory (relative standard deviation less than 15 %). The detection limits are also accepta…

Polycyclic aromatic hydrocarbons (PAHs) in the polychaete Sabella spallanzanii, as a reliable bioindicator, by GCMS

2012

Every year 230.000 tons of PAHs enter the marine environment, resulting ubiquitously distributed worldwide. These compounds are aromatic molecules of special concern because of their toxic and carcinogenic properties. As a consequence of their hydrophobic nature, in aquatic environments, PAHs rapidly tend to associate with particulate matter and sediments represent the most important reservoir. In the present study the level of PAHs in the sessile filter-feeder polychaete Sabella spallanzanii was assessed. In particular, the concentration of PAHs was determined in polychaetes (body and tube) collected from three Sicilian areas, subject to different anthropic pressure. A transplanting experi…
