“…A submersible PrimProd fluorometer was used to collect the measurements, registering in situ fluorescence of phytoplankton photosynthetic apparatus. Lake Gardno is one of nine coastal lakes that have rather unique characteristics, classified as a separate group in the Polish typology according to the requirements of the EU Water Framework Directive (Kolada et al 2005). This group of lakes has been relatively little studied as compared to other types of Polish lakes, and so this study is in response to a need for basic data.…”

In 2006 the spatial distribution and seasonal variations in chlorophyll concentration were measured, at about two-week frequency, in Lake Gardno. In general, chlorophyll concentrations in the central part of the lake were high throughout the growth season. The minimum chlorophyll concentration was recorded in March (7.5 mg m -3 ), and the maximum value in September (303 mg m -3 ). Higher chlorophyll concentrations and lower temporal variability were measured in the central part of the lake, compared to lower concentrations and higher variability in the vicinity of the Łupawa River input to the lake. Chlorophyll concentrations were measured fluorometrically along several vertical and horizontal profiles, enabling direct observations of the dynamics of changing chlorophyll concentrations in Lake Gardno throughout the year.

Establishing reference conditions is essential for performing ecological status assessments of surface waters according to the EU Water Framework Directive. Ecological status is described as the deviation from undisturbed (reference) conditions. This paper presents the process of establishing preliminary reference values for chlorophyll a, total phosphorus, and Secchi disc readings in different types of Polish lakes. This was done by selecting potential reference lakes and performing statistical analysis of the values of the main eutrophication parameters. The preliminary reference values for total phosphorus, chlorophyll, and Secchi disc depth were defined as 0.033 mgP dm -3 , 3.75 μg dm -3 , and 3.6 m for stratified lakes, and 0.048 mgP dm -3 , 5.80 μg dm -3 , and 2.5 m. for polymictic lakes, respectively.

“…-lakes with different mixing types: stratified and non-stratified, according to Polish abiotic typology (KOLADA et al 2005) belong to 2a, 3a, 5a, 6a and 2b, 3b, 6b, respectively. In stratified lakes, samples were collected from the euphotic zone -in spring and autumn and from the epilimnion in summer; in non-stratified lakes they were taken from the whole depth.…”

A new phytoplankton-based method (the Phytoplankton Metric for Polish Lakes -PMPL) for the ecological status assessment of lakes has been developed in Poland. This method has not been validated and tested on independent data, hence the aim of the study was to check the applicability of this method and the sensitivity of different phytoplankton metrics along pressure gradient. Phytoplankton data were collected from 33 Polish lowland lakes (20 stratified, 13 non-stratified), during the growth season in the period from 2005 to 2009. The biomass of phytoplankton was calculated from cell volume measurements and chlorophyll a concentration was determined spectrophotometrically by the alcohol method. Total nitrogen and total phosphorus concentrations were determined by standard methods (PN-EN ISO 6878:2006p.7 and PN-EN 25663:2001, respectively) and water transparency was measured using a Secchi disk.For comparability, an ecological status was determined according to three phytoplankton-based methods: Polish, German and Hungarian. Polish metrics showed a strong correlation with the other metrics (German, Hungarian), which are broadly and successfully used for assessment in Europe. However, a statistically significant correlation was found between all the metric values and the main parameters: total phosphorus, total nitrogen and Secchi disk visibility. The metrics based on quantitative phytoplankton features were more sensitive to the growth of eutrophication than others, based on indicator taxa. Total phosphorus demonstrated a stronger relationship with the tested metrics than total nitro-290 gen. Phytoplankton metrics reacted quite well to pressure gradients because of the decreasing tendency of metric values along the TP and TN gradient and an increasing tendency along the Secchi disk visibility gradient. The multimetric PMPL may be recommended as useful for the assessment of the ecological status of Polish lakes.Key words: WFD, ecological status assessment, phytoplankton-based method, PMPL, PSI, Q Index. ODPOWIEDZ METRIKSÓW FITOPLANKTONOWYCH NA WZROST GRADIENTU FOSFORU I AZOTU W JEZIORACH P£YTKICHAbstrakt W Polsce opracowano now¹ metodê do oceny stanu ekologicznego jezior na podstawie fitoplanktonu (polski multimetriks fitoplanktonowy -PMPL). Metoda ta nie zosta³a zwalidowana i przetestowana na niezale¿nych danych. Celem badañ by³o sprawdzenie mo¿liwo-oeci zastosowania tej metody oraz wra¿liwooeci ró¿nych metriksów fitoplanktonowych na gradient presji. Polskie metriksy wykazywa³y siln¹ korelacjê z innymi metriksami (niemieckimi i wê-gierskim), które s¹ szeroko stosowane do oceny stanu ekologicznego w Europie. Statystycznie istotne korelacje wykazano równie¿ miêdzy wartooeciami metriksów a g³ównymi parametrami presji, fosforem i azotem ogólnym oraz widzialnooeci¹ kr¹¿ka Secchi'ego. Metriksy oparte na cechach ilooeciowych fitoplanktonu by³y bardziej wra¿liwe na wzrost stopnia eutrofizacji ni¿ inne, oparte na taksonach wskaŸnikowych.
