Jagusiewicz, A.
La reduction des emissions d'ammoniac pour atteindre des objectifs environnementaux tels que stopper la diminution de la superficie des ecosystemes non proteges contre l'acidification et l'eutrophisation va occuper une place de plus en plus importante dans la strategie de lutte contre la pollution. En raison de la reduction des emissions d'oxydes de soufre et d'azote operee au cours des 20 dernieres annees dans le cadre de la Convention sur la pollution atmospherique transfrontiere a longue distance, il est fort probable qu'en 2010 c'est l'ammoniac qui contribuera le plus aux emissions gazeuses responsables de l'eutrophisation et de l'acidification. D'ou l'importance de prendre des maintenant des mesures efficaces contre ce polluant, et ce a l'echelle continentale

As part of the Canadian Great Lakes Action Plan, the transport and effect of non-point source agricultural contaminants in wetlands were evaluated. Due to the broad scope of this study, the abilities of many individuals with different domains of expertise were employed. Stages of the study reported here include: 1) Survey of cropping and pesticide/fertilizer practices of farms in the selected watersheds; 2) Sampling and analysis of creek water and sediments for pesticides and other parameters; 3) Study of the reversible "loss" of pesticides by adsorptive and diffusive interaction with sediment particles; 4) Investigation of the effect of the agricultural contaminants on macrophytes and invertebrates. Among the findings of this work were the detection of some pesticides years after their last use as well as the presence of microorganisms, in all creek sediments tested, capable of rapidly and completely mineralizing atrazine.
