In the last decades the creation of new Environmental Specimen Banks (ESB) is increasing due to the necessity of knowing the effects of pollutants in both the environment and human populations. ESBs analyze and store samples in order to understand the effects of chemicals, emerging substances and the environmental changes in biota. For a correct analysis of the effect induced by these variables, there is a need to add biological endpoints, such as biomarkers, to the endpoints based on chemical approaches which have being used until now. It is essential to adapt ESB´s sampling strategies in order to enable scientists to apply new biological methods. The present study was performed to obtain biochemical endpoints from samples stored in the BBEBB (Biscay Bay Environmental Biospecimen Bank) of the Marine Station of Plentzia (PIE - UPV/EHU). The main objective of the present work was to study the variability caused in biochemical biomarkers by different processing methods in mussels (Mytilus galloprovincialis) from two localities (Plentzia and Arriluze) with different pollution history. It can be concluded that the selected biomarkers (glutathione S-transferase and acetylcholinesterase) can be accurately measured in samples stored for years in the ESBs. The results also allowed the discrimination of both sampling sites. However, in a further step, the threshold levels and baseline values should be characterized for a correct interpretation of the results in relation to the assessment of the ecosystem health status.

[EN]If a frog is placed in boiling water, it will jump out; but if it is placed in cold water that is slowly heated, it will not perceive the danger and will be cooked to death. Without de ability to observe changing environmental conditions, the frog can find itself boiled alive before realizing it is in trouble. This is known as the boiling frog syndrome. In the same manner, it is impossible to be competitive without knowing and being aware of the environmental changes. From here comes the necessity for the Technological Watch and Competitive Intelligence. The main goals of this project are to evaluate the current Technological Vigilance System of the IK4-Tekniker research center and to develop services that help in improving the system. For that purpose, first of all the Technological Vigilance is going to be placed in the business field and its origins are going to be explained. Following that, the Technological Vigilance system of IK4-Tekniker is going to be analyzed for its evaluation. Finally the creation of the services previously mentioned are going to be described in detail, showing the technologies and tools used for that purpose like the Responsive Web Design.
