| Summary: | International audience After a mass mortality of fish in river Rhine, determinations of various toxichemicals (Mercury and organochlorine compounds) were made in five species of fish and in the eggs of six species of birds. The high concentrations of these pollutants found both in fish and birds quite probably explain their increased mortality rate during the period 1973-1975 it might also be responsible for some abnormal behaviour patterns recently noticed among gulls. Les auteurs relèvent la présence de polluants dans la zoo- coenose rhénane suite à une vague de mortalité de poissons et d’oiseaux de 1973 à 1975. Les analyses mettent en relief l’impor tance de l’intoxication mercurielle (18 ppm de mercure dans le foie d’une Sterne pierregarin) et des organochlorés. |
