Automated, Rapid And Reliable Determination Of Dissolved Gases In Water By Static Headspace – Gas Chromatography
A. Caruso, M. Santoro, F. Bedini, P. Magni, S. Pelagatti

Purpose: Exploring the possibility to perform a quantitative determination of dissolved gases in water in a reliable and accurate way. Methods: The quantification of dissolved gases is performed by building a calibration curve spiking blank water samples with increasing quantities of saturated water followed by headspace sampling and GC/ FID analysis. Results: The results show good correlation factors and limit of quantification lower than 10ppb for the four gas analyzed.

GC-MS Comparison of Lavindin Grosso Oil Obtained by Steam Distillation and SFE
Claudia Worley, Lisa Zona, Susan Sonchik Marine

Oil was extracted from Lavindin Grosso using steam distillation and using supercritical fluid extraction (SFE). Multiple analyses of the same extract demonstrated repeatability of the analytical method. The variability between batches of distillate bracketed the composition obtained by SFE. The differences among the oils could be attributed more to where the lavender was grown than to the extraction method.

New Sorbent from Agro-industrial Waste and its Potential Use in 17ß-Estradiol and 17α-Ethynylestradiol Removal
Suzimara Rovani*, Éder C. Lima, Renato Cataluña, Andreia N. Fernandes

In recent years, the increasing introduction of new chemicals in the market, and the development of more accurate analytical methods, added a variety of endocrine disruptors compounds (EDC). Even though they are found in very low concentrations (range of ng L-1) there is still a lack of knowledge about long-term risks of EDC for non-target organisms as well as for human health.

Identification and classification of antifouling compounds secreted by anti MIC microorganisms. A metabolomic analysis.
Albillos SM; Balaña-Fouce R; Montero O; Barreiro-Mendez C; Blas-Galindo E; Barros-García R; Guedella-Bustamante E; Ullán RV

BIOCORIN project, aims to develop a green alternative to the coatings and solutions used up to date for MIC corrosion control. Some of the results of this project are presented here, with the identification of several relevant antifouling compounds secreted by environmentally isolated anti-MIC strains of microorganisms via a metabolomic approach.
