Impact of environmental pollutants on benthic diatoms
The aim of the project is to test the possibility of developing benthic diatoms indicators for hazardous substances in Swedish inland waters.
To meet the demands of the Swedish Environmental Objective 'A Non-Toxic Environment' and to screen streams and lakes for prioritized substances, there is a need to find indicators, which can show the integrated effect of environmental pollutants such as heavy metals and pesticides.
