Sažetak
Algae and aquatic plants have a major role in the environmental conditions of stagnant and flowing waters, being important in the uptake, storage, release and deposition of nutrients (Fairchild et al. 1998). Much of the research has focused on the phytoplankton. Algae have been shown to be sensitive to a wide range of contaminants. Thus, algae have been recommended for use in regulatory testing (Halling-Sorensen et al. 1996). The potential effects of herbicides on aquatic primary producers are particularly important, and need to be studied in ecotoxicological experiments (Ma 2001). Due to the high costs of chronic toxicity testing with algae there have been several approaches to develop and establish miniaturized bioassays using algae (Eisentraeger et al. 2003). The objective of this study was to evaluate the sensitivity of the freshwater green algae Pseudokirchneriella subcapitata, Desmodesmus subspicatus and Chlorella kessleri to selected herbicides using standard Erlenmeyer flask and miniaturized microplate algal growth inhibition assays and to compare sensitivity among populations of these three green algae to the herbicides metribuzin, alachlor and isoproturon.
