    Sammanfattning : Benthic diatoms are unicellular, brown algae with siliceous cell walls. They are often used to show water quality in river sand lakes. Benthic diatoms can show elevated nutrient levels, very acid conditions, pollution by organic matter and probably also pollution by heavy metals, which makes them useful biological indicator species.
