Résumé : International audience
An inter-laboratory exercise was organized under the PHARMAS EU project, by the Advanced School of Public Health (EHESP), in order to evaluate the performances of analytical methods for the measurement of antibiotics in waters (surface and tap). This is the first time such an exercise on antibiotics has been organized in Europe, using different kinds of analytical methods and devices. In this exercise thirteen laboratories from five countries (Canada, France, Italy, the Netherlands and Portugal) participated, and a total number of 78 samples were distributed. During the exercise, 2 testing samples (3 bottles of each) prepared from tap water and river water, respectively, spiked with antibiotics, were sent to participants and analyzed over a period of one month. A final number of 77 (98.7%) testing samples were considered. Depending on substances studied by each participant, 305 values in duplicate were collected, with the results for each sample being expressed as the target concentration. A statistical study was initiated using 611 results. The mean value, standard deviation, coefficient of variation, standard uncertainty of the mean, median, the minimum and maximum values of each series as well as the 95% confidence interval were obtained from each participant laboratory. In this exercise, 36 results (6% of accounted values) were outliers according to the distribution over the median (box plot). The outlier results were excluded. In order to establish the stability of testing samples in the course of the exercise, differences between variances obtained for every type of sample at different intervals were evaluated. The results showed no representative variations and it can be considered that all samples were stable during the exercise. The goals of this inter-laboratory study were to assess results variability when analysis is conducted by different laboratories, to evaluate the influence of different matrix samples, and to determine the rate at which participating laboratories successfully completed the tests initiated.

Résumé : International audience
Although earthquakes and tsunamis are less frequent in the Dover Straitthan over active subduction zones, a plausible potential exists for intraplate earthquakes of magnitude Mw=6.9 generating a tsunami with damaging consequences. In April 1580, an earthquake shook the region violently and destructions were reported as far as London in the north andRouen in the south. Despite fair weather conditions, a series of abnormal sea waves was reported in several harbours (Calais, Boulogne and Dover) on the same day. A first step was to produce a range of numerical coseismic tsunami simulations and to compare them with historical witness accounts. Results raise the question of whether such earthquakes could also triggerchalk flow-generated tsunamis along cliff lines on both sides of the Strait. Gravity-driven collapses affect thechalk cliffs periodically, but local tsunami waves caused by very large mass movements could reach heights of several meters and, for example, strike Dover.

Résumé : The fish assemblages of two artificial reef systems of the south coast of Algarve (Portugal) are presented, and a comparative study is made of their species richness variation according to their location off the Ria Formosa lagoon. Each system consists of a protection reef and an exploitation reef. Gillnets, traps, longline and visual census were used as sampling techniques. Both reefs showed similar species richness, in each case higher than that of Ria Formosa. No significant differences of species richness were found between the reef systems (p = 0.1). However, the exploitation reefs showed a significant difference of species richness, that was more evident when accumulated species richness was used to compare them (p = 0.01).
