AIM: The main objective of this work is to describe the changes in water characteristics of a shallow subtropical lake, in periods with and without growing of macrophytes, related to periods of clear-macrophyte dominance and turbid-phytoplankton dominance states. METHODS: The study was conducted in Biguás Lake, in the south coastal plain of Brazil (32° 04' 43" S and 52° 10' 03" W). Samplings were carried out monthly between October 2000 and November 2013. The limnological variables measured in the water column were dissolved oxygen (DO), water temperature, pH, electrical conductivity (EC), chlorophyll-a, total nitrogen (TN), total phosphorous (TP) and suspended material (SM). Data were grouped according to periods with macrophyte growth dominance (MD) and without macrophytes, with phytoplankton dominance (PD), and applied t- tests among TP, TN, Chlorophyll-a and SM. During macrophyte growth we estimated the coverage (%) and biomass variation of plants. RESULTS: Over the 13 years, the lake was well oxygenated, alkaline, and with a temperature variation according to subtropical seasonality. The lower values of all of the limnological variables were verified during periods of macrophyte growth, characterizing periods of clear and turbid waters. CONCLUSIONS: The influence of aquatic macrophytes in improving water quality in this shallow lake during the studied period, reducing nutrient concentrations, chlorophyll-a and suspended material in water, favoring the maintenance of a clear water state, was verified.

Metallic elements in the water have been rapidly increased due to the high population growth, urbanization, and industrialization. Metals which have high density and high atomic weight are non-degradable, they persist in various environs, have the potentiality to enter the food chain or food web. Due to their toxic nature, heavy metallic contamination has become the most hazardous pollutant in the growing world. Therefore, reduce or remove water contamination is the predominant importance. Utilization of plants to refine water quality is a green technology, which is an effective method, environment-friendly and consumes fewer energy inputs, and also carried out less amount of cost. In this review article, we enlighten the potential of various aquatic macrophytes to reduce or remove the heavy metal contaminants from the aquatic eco-system.

Abstract With its diversity of water body types, the Danube Delta offers large possibilities for studies of aquatic macrophytes, their ecological requirements, ecological amplitude and communities. Sensitive to changes in water quality and physical parameters due to human intervention in the natural ecological network, aquatic macrophytes are used as quality indicators. Using the example of the system of channels and lakes of the Gorgova-Isac-Uzlina complex and some examples from the neighboring area, the aquatic macrophytes and their communities are presented and discussed in relation to the characteristics of the habitats and the changes of the environment in the course of decades, since human intervention in the delta.
