Cyanobacterial blooms cause potential risk to submerged macrophytes and biofilms in eutrophic environments. This pilot-scale study investigated the growth, oxidative responses, and detoxification activity of aquatic plants in response to cyanobacterial blooms under different phosphorus

We studied the antioxidant responses of macrophyte Vallisnerria natans seedlings to combined ammonia (0, 0.21, and 0.85 mg L(-1)) and microcystin-LR (MC-LR) (0, 10, and 50 μg L(-1)) for 7 days. Results showed that superoxide dismutase, catalase (CAT), peroxidase, and glutathione were significantly

With indoor static stimulation test, this paper studied the effects of different concentrations (0.01, 0.02, 0.05, 0.07 and 0.1 mg x L(-1)) pyrene on the pyrene accumulation, free radical, antioxidant defenses, and the contents of chlorophyll and soluble sugar in Vallisneria spiralis. The results

Phytochelatins (PCs) have been involved in metal detoxification, and used as potential biomarkers for an evaluation of metal toxicity. However, most studies have generally been limited to high concentrations of metals. In this study, low concentrations of cadmium (Cd) (0.01-0.64 microM) usually

Ammonia (i.e. the total of NH(3) and NH(4)(+)) has been one of the main causes of the decline of macrophytes in fresh water. In order to study the effects of ammonia toxicity, plants of the submersed macrophyte Vallisneria natans (Lour.) Hara were treated with various concentrations of NH(4)Cl (0.1,

The effects of Pb on photosynthetic pigments, oxidative stress and antioxidant response were assayed using biochemical and histochemical methods in leaves of Vallisneria natans (Lour.) Hara treated with 0-100 μM Pb(2+) for 0-6d. The Pb content increased with the increase of exposure duration and a

Microcystins produced by cyanobacteria in the aquatic environment are a potential risk to aquatic plants. In the present study, the uptake of microcystin-LR (MC-LR) and related physiological and biochemical effects on Vallisneria natans (Lour.) Hara were investigated at concentrations of 0.1-25.0 μg

Hazardous substances, such as anatoxin-a and microcystin-LR, are released into the aquatic environment during cyanobacterial blooms, causing significant ecological risk. To assess the toxic effects of anatoxin-a, microcystin-LR and their combined exposure on submerged macrophytes and biofilms,
