Can anyone help me with detail information on how macrophyte and phytoplakton can be use simontaneously in assessment of the ecological state of aquatic environment. what statistic can be use to present the result and what parameters i can use for the monitoring method? is it neccessary to analyse the plants for heavy mental too?
Please go through the following resources.

It is necessary to evaluate the metal content of plant absorb through the root system of the plant then go to the flowers/fruits/apical regions to better understanding of heavy metals accumulated. Chromatography will be the cheapest test for for it.
In fact, Aquatic species are of the
plants that have high potential for the
phytoremediation of water contaminated with heavy
metal,nitrates and phosphate
Dear Enodiana,
for assessment of the ecological state of the aquatic environment, you can quantify of chlorophyll-a concentration in collected water sample to predicting the level of eutrophication using Trophic State Index (TSI) according to Carlson (1977).
using Phytoplankton species diversity
and calculate Shannon-Wiener diversity index (H′), where it is one of the most
widely used indices for measuring diversity. It can change with key ecological factors such as competition, predation, and succession altering the diversity through changes in evenness without any change in species richness. also, you can use Shannon-Wiener index as a pollution index in diatom communities and suggested the following scale: 0–1 for high pollution, 1–2 for moderate pollution, 2–3 for marginal pollution, and 3–4 for incipient pollution or use palmer′s pollution index (Palmer, 1968) as an organic pollution index. you can determine Physico-chemical parameters in water samples like temperature, pH, TDS, DO, ammonia, nitrate, nitrite, phosphate,...
use canonical correspondence analysis (CCA) to examine the environmental variables influencing the phytoplankton community and it is very good analysis to present your final data.
good luck,

In the aquatic environment, algae and plants accumulate substances through the thallus and leaves (as in the case og angiosperm e.g. Posidonia oceanica) respectively, while the root system act as the base of the organism. In the case of e.g. radionuclides and metals in the marine environment, brown algae (e.g. Cystoseira) seem to bioaccumulate in higher level, while the the leaves of the adult angiosperms are the respective part with the higher accumulation.
