Lake Garda - trophic evolution and current environmental conditionsFunded under: FP1-ENVIRO 4C
This study was performed to fill the existing gaps in the knowledge of the limnological conditions of Lake Garda. The enquiry, carried out from September 1988 to September 1989, examined four pelagic stations in which 1815 samples were collected and a total of over 20,000 analytical determinations were made. The picture which emerges from this research shows that the Benaco's actual trophic state is situated in the lower limit of mesotrophy. As for the nutrient loads which still affect the lake, they must be reduced by a further 65% in order to attain the final objective laid down by the General Water Clean-up Plan of the Lombardy Region. Concerning the presence of heavy metals and organic micropollutants in lake waters and in some fish species, the present levels are considerably lower than those laid down as acceptable for human consumption. No significant contamination with heavy metals and organic micropollutants was found in lake sediments.
