Marine grade oil adsorption performance of artisanal felt mat made using waste human hair.

This is an experimental study that aims to use waste hair in the fight against oil pollution in the sea and to support the art of felt making, which is in danger of extinction. In this way, it is aimed to contribute to sustainability by producing a product for environmental improvement from waste material that does not have any value, and by creating employment by preserving a handicraft with historical basis. As a result of the experiments, it was observed that adsorbent materials made from sheep wool with human hair added in different proportion showed adsorbent performance comparable to their equivalents and superior to some of them.

Heavy metals contamination levels at the Coast of Aliaga (Turkey) ship recycling zone.

Aliaga Bay is one of the most important maritime zones of Turkey where shipping activity, shipbreaking industry, steel works and petrochemical complexes exist together. Concentrations of heavy metals and organic carbon in sediment of the Aliaga Bay were investigated to evaluate an environmental risk assessment from metals contamination in 2009-2010. Comparison of the metal concentrations with average shale and Mediterranean background levels revealed that most of the samples from the Aliaga were polluted with Hg, Cd, Pb, Cr, Cu, Zn, Mn and Ni. It was found that Hg, Pb, Cu, Zn and Ni levels in Aliaga Bay exceeded the PEL values. Sediments, contaminated with Pb, Cr, Cu, Zn and Ni were considered as heavily polluted per the SQG.

Polycyclic aromatic and aliphatic hydrocarbons pollution at the coast of Aliaga (Turkey) ship recycling zone.

Aliaga Bay is one of the most important maritime zones of Turkey where shipping activity, shipbreaking industry, steel works and petrochemical complexes exist together. Polycyclic aromatic hydrocarbons (PAHs) and aliphatic hydrocarbons in sediment of the Aliaga Bay were investigated to evaluate an environmental risk assessment from PAHs contamination in 2009-2010. Aliphatic and PAHs diagnostic ratios were showed to be mainly petroleum-originated and pyrolitic contaminations, respectively. The TEL/PEL analysis suggests that Aliaga sediments were likely to be contaminated by acutely toxic PAH compounds.
