| An intercalibration exercise on the characterisation of microplastics in marine sediment and water samples was carried out among five laboratories involved in the implementation of the Marine Strategy Framework Directive (MSFD) in their country. The samples were prepared by mixing cleaned natural sediment and sea water with microplastics sets made of particles of various polymers, shapes and colours. Overall, the errors on total counts were under 25% in absolute value. The risk of non-detection and loss of particles is greater than the risk of contamination during sample analysis. Significant differences are observed among particle types. It appears difficult to obtain reliable and comparable data on the colour of microplastics. A comparison of the errors... |

| Considering the necessity for standardization of toxicity tests and the need for simple and reliable routine tests, the <i>Artemia</i> Reference Center at the State University of Ghent in Belgium has developed a short term standard toxicity test with <i>Artemia</i> nauplii. This simple and inexpensive bioassay which can be used as a screening test to determine the toxicity of chemicals to aquatic organisms, has been discussed in detail during a special workshop devoted to toxicity tests with brine shrimp, at the occasion of the "International Symposium on the brine shrimp <i><i>Artemia</i> salina</i>"(Corpus Christi, Texas, USA; August 1979). Besides a few minor modifications, the test methodology was... |
