The data catalog allows you to consult and download data from the annual monitoring and reports of the complementary studiesstudies
Complementary studies allow to strengthen the analysis of the state of health of Lake Geneva
Given the large number of parameters andand the limited resources available to study them, it is notto study them, it is not possible to monitor to monitor everything, in all compartments, every day of the year.
To find a reasonable equibetween the information that can be and the cost of monitoring, the CIPEL isthe CIPEL relies on on the complementarity between a regular regular and annual monitoring program (temperature, phosphorusphorus, oxygen, plankton, micropollutants in water, etc.) micropollutants in water, etc.) and complementary studies, more (aquatic vegetation, micropollutants in fish, musselsmicropollutants in fish, mussels or sediment, etc.), in order toments, etc.), in order to consolidate an overall picture of theof the state of health of Lake Geneva
Scientific studies carried out by CIPEL:
The sediments
Studies of the sediments of Lake Geneva to measure the evolution of nutrient (in particular phosphorus) and metallic micropollutant contents, as well as the presence of certain organic micropollutants, and even microplastics.
organic micropollutants and even microplastics.
The flesh of the fish
Analyses of micropollutants in fish flesh to monitor the evolution of contamination (PCB and mercury) in the environment and analyses of microplastics to extend the studies already conducted on plastic fragments in the sediments of Lake Geneva.
Wastewater treatment plants
Modeling study of micropollutant inputs by wastewater treatment plants in order to draw up different reduction scenarios depending on the type of treatment.
Invasive alien species
Inventory of exogenous invasive species on the lake shore to record the presence and location of 12 species considered the most problematic.
Phytosanitary products
Characterization study of the risks of transfer of phytosanitary products of agricultural origin to surface waters.
Macrophytes
Inventory of the macrophytic vegetation of Lake Geneva to follow the evolution of the quality of the environment.
Diffuse phosphorus
Evaluation of diffuse phosphorus inputs to Lake Geneva.
The quagga mussel
The quagga mussel is an emerging invasive alien species in Lake Geneva. CIPEL has launched a first phase of study in order to better understand it and to be able to act more efficiently.
