Une étude de l'Eawag et de l'université de Zurich a révélé des faits surprenants : elle montre, grâce à une nouvelle technique d'imagerie, que la cocaïne s'accumule dans les yeux des poissons zèbres. Les résultats indiquent que, dans le contexte aquatique, l'évaluation des polluants, et en particulier des psychotropes, doit être conçue différemment, par exemple, des tests de médicaments sur les rongeurs. Et ils montrent surtout qu'il est encore hasardeux de transposer à l'homme ou aux mammifères les connaissances sur les mécanismes d'absorption et d'action de la cocaïne acquises sur les poissons.
