Coontail (Ceratophyllum demersum L.) plants when exposed to various concentrations of Pb (1-100microM) for 1-7days, exhibited both phytotoxic and tolerance responses. The specific responses were function of concentration and duration. Plants accumulated 1748mugPbg(-1) dw after 7d which reflected its

Cadmium (Cd) contamination of aquatic systems is of major concern since it is a nonessential element and hampers plant growth upon accumulation. The aim of this study was to investigate the Cd accumulation behavior of coontail plant, Ceratophyllum demersum L., toxicity induced and response of the

During senescence, leaves are deposited on aquatic bodies and decay under water releasing chemical substances that might exert physiological stress to aquatic organisms. Leaf litter alone contributes 30% of the total dissolved organic carbon (DOC) in streams. We investigated the impact of leaves

Microcystins (MCs) produced by cyanobacteria in natural environments are a potential risk to the integrity of ecosystems. In this study, the effects of cyanobacterial cell-free crude extracts from a Microcystis aeruginosa bloom containing three MC-congeners MC-LR, -RR, and -YR at environmental

Surfactants and phenolic compounds are common organic pollutants in aquatic and terrestrial ecosystems. However, the ecological risks of their combination are still unknown. This study investigated the effects of sodium dodecyl sulfate (SDS), phenol and their mixture on the growth and physiological

We report the effects of 1,2- and 1,4-dichlorobenzene (1,2-DCB and 1,4-DCB) on the aquatic macrophyte Ceratophyllum demersum. We evaluated the response of the antioxidant system through the assay of glutathione reductase (GR), guaiacol peroxidase (POD) and glutathione peroxidase (GPx). Additionally,

Ceratophyllum demersum L. is known to be a potential accumulator of arsenic (As), but mechanisms of As detoxification have not been investigated so far. In the present study, we analyzed the biochemical responses of Ceratophyllum plants to arsenate (As(V); 0-250 microM) exposure to explore the

Laboratory experiments were carried out to investigate pyrene bioaccumulation and its consequent biological responses in submerged macrophyte Ceratophyllum demersum. Plants were exposed to different levels (0.01, 0.02, 0.05, 0.07, 0.1 mg/L) of pyrene for 10 days, and the pyrene content, and total

4-tert-octylphenol (OP) is a persistent environmental pollutant with an endocrine-disrupting property. In the present study, we examined the effect of various concentrations of OP (0, 0.5, 1, 1.5, 2 and 3 mg L-1) applied to an aquatic plant, the submersed macrophyte Ceratophyllum demersum. The toxic

This study aimed to demonstrate the ways in which two chromium species, Cr (III) and Cr (VI), can affect various physiological and biochemical parameters in the plant Ceratophyllum demersum L., and to evaluate the single and combined impact of exposure concentration and duration. C. demersum was

Anatoxin-a is one of the common and major cyanobacterial neurotoxins acting as a powerful agonist at nicotinic acetylcholine receptors (nAChR). In recent years, the toxin has become the focus of public attention, due to the mass development of cyanobacteria (cyanobacterial blooms) in freshwater

Cyanobacterial toxins have been shown to have adverse effects on mammals, birds and fish and are therefore being increasingly recognised as a potent stress and health hazard factor in aquatic ecosystems. Microcystins, which are cyclic heptapeptides and a main group of the cyanotoxins, are mainly

In the present study, two fresh water plant species Egeria densa (Planch.) Casp. and Ceratophyllum demersum L. were subjected to separate and combined action of urea (2mМ) and metals (Ni and Cu, 10μM) to investigate the phytoremediation potential of these two submerged macrophytes during short-term

Recently, aquatic macrophytes have been considered as promising tools for eco-friendly water management with a low running cost. However, only little information is available thus far regarding the metabolic capacity of macrophytes for coping with cyanobacterial toxins (cyanotoxins) in the aquatic

We examined the uptake of five heavy metals (Cu, Fe, Ni, Zn, and Mn) in Ceratophyllum demersum L. (hornwort) and Potamogeton alpinus Balb. (pondweed) from Iset' river, Ural region, Russia. This study was conducted in a territory that is highly urbanized where the surface waters are contaminated by a
