Abstract: | Littoral diatoms are important contributors of the primary production in shallow aquatic ecosystems and they can be used as
indicators of the trophic status. The aim of the study was to develop an index to assess trophic status of Hungarian lakes
as suggested by the Water Framework Directive. In spring of 2005 and 2006, epiphytic diatom samples were collected from 83
shallow lakes. Weighted average method was used to develop and test the TP model. In the developed TP model correlation between
the observed and diatom inferred TP was high (r
2 = 0.96, n = 67). The optimum and tolerance TP parametrics of 127 species were determined and trophic indicator and sensibility values
were defined for the Trophic Diatom Index for Lakes (TDIL). The TDIL was applicable to assess the ecological status of Hungarian
shallow lakes. According to the TDIL the ecological status of 4 lakes were in excellent, 25 in good, 21 in medium, 21 in tolerable
and 12 in bad status.
