“…Common physico-chemical properties of metal substrata that could infl uence the settlement of organisms are their high surface energy and hydrophilicity. High surface energy of metal surfaces could promote adhesion, but is soon after immersion reduced by the adsorption of organic particles (KINLOCH 1990;CAILLOU et al 2008). Hydrophilicity of metal surfaces, as shown in several previous studies (PEDERSEN 1990;BECKER and WAHL 1991;BECKER 1996), makes adhesion of diatoms more diffi cult as opposed to adhesion on hydrophobic surfaces.…”

-The settling of diatoms as fouling organisms on a certain substrate is greatly infl uenced by substrate characteristics and the preferences of a diatom community and diatom species. A distinction among substrates can be made by analysing the specifi c abundance and composition of diatoms on different substrates. In this study, 11 different artificial substrates were exposed to a marine environment for a period of 30 days. Abundance and taxonomic composition of periphytic diatoms was determined on each of the substrates and on shoots of the marine seagrass Posidonia oceanica. The aim was to compare diatom community structure on different newly colonized surfaces. On all surfaces examined, periphytic diatoms were the pioneering organisms with differences in quantitative and qualitative composition on the different substrates. Taxonomic analysis of diatom communities on the substrates examined revealed 41 diatom taxa, with the dominant genera Cylindrotheca, Amphora, Nitzschia, Cocconeis and Navicula. Given that all the examined artifi cial substrates were solid materials, differences in the abundance and species composition of diatoms found between the materials point to the substrates' physical and chemical characteristics as a major infl uence on the fi nal settling of diatoms. Knowledge from investigating the settlement of fouling organisms on anthropogenic substrates can have future use in management of waste materials that end up in the marine environment.

“…This difference may not be due to an orientation of the polymer segments at the surface, given the structure of the repeat unit [-CH 2 -CH(-NH-CH 3 )-] and the analyzed depth. It is attributed to the simultaneous presence at the surface of PAH and organic contaminants (Caillou et al, 2008). As the N/C ratio does not vary with , the adsorbed organic layer appears to be a mere mixture, with no preferential accumulation of a component at the outermost surface.…”

“…Both compounds are due to adventitious contamination which may originate from adsorption from air, as always observed for high surface energy solids (Caillou et al, 2008;Mantel et al, 1995), but also from aqueous media (Landoulsi et al, 2008a). They may be taken as a global way to reflect the amount of compounds which contain hydrocarbon chains and oxygen, such as esters, but excluding proteins and silane.…”

“…Moreover organic contaminants are always present on high energy solids. They are mainly of hydrocarbon nature and are readily adsorbed from surrounding air or in surface analysis spectrometers (Caillou et al, 2008;Landoulsi et al, 2008a). The possible influence of contaminants on the silanization process and product is usually not considered.…”
