| الوصف: | The BBLOOMS project was a two-year program, which was primarilyproposed to make a first assessment of the extent of present cyanobacterial bloomsin Belgium and of the potential threat for the surface water resources. In this study,we addressed several aspects: (i) the extent and phenology of nuisance blooms inmultiple-use Belgian surface waters, (ii) the taxonomic diversity of bloom-formingcyanobacteria, using traditional and genetic tools, (iii) the use of genetic markers toestimate whether the organisms are potentially toxic, (iv) the measurement of toxinconcentration in field samples, and (v) the relationship between environmentalvariables and nuisance blooms in selected water bodies. Most field samples camefrom 4 reference lakes (Blaarmeersen lake in Flanders and three pre-dam lakes ofEau d’Heure in Wallonia) that were monitored intensively for 2 years. Twenty-threesamples were taken for Blaarmeersen, in a continuous manner. Seventy-threesamples were studied for the Eau d’Heure complex, but only when proliferationswere observed. Additional samples were provided by summer samplings in a seriesof small lakes in Flanders carried out by the University of Gent. As this wasinsufficient to obtain a global view of the phenomenon, we have built BLOOMNET, anetwork of water managers and users, who received information aboutcyanobacterial blooms and how to collect them for subsequent analysis. The networkcontributed about forty samples from all regions. |
