cadmium is a highly toxic heavy metal and one of the most important environmental pollutants. cadmium has a particular interest among the heavy elements due to the high mobility, solubility, and toxicity for human, plants, and other organisms. in order to study cadmium toxic effect on green pepper, a completely randomized design was performed with three levels of cadmium (0, 0.25, and 0.5 mm as...

Toxicity tests were performed to assess the effect of tannery wastewater with different treatment levels on two wetland plants, Phragmites australis and Typha latifolia, which are frequently used in constructed wetlands (CWs) for water treatment, and thus deepen the knowledge on their capacity to withstand the application of industrial wastewater. Trifolium pratense, a plant generally used as a...

Lead is a nonessential element that has a negative effect on plant growth and development. Plant symbiosis with arbuscular mycorrhizal fungi (AMF) in soils contaminated with heavy metals can affect growth of plant, nutrition and tolerance against heavy metals. In this study, the effect arbuscular mycorrhizal fungi Glomus intraradices on the growth, photosynthetic pigments, protein content, prol...

The possible toxicity of a commercial chlorine dioxide preparation (Halox E-100) was evaluated on radish and lettuce seedlings growing in pots under controlled conditions. A single application of various dilutions to radish seedlings growing in a sterile or nonsterile commercial plant substrate only slightly decreased plant dry weight. At the end of the experiments, the plants appeared unaffect...

Insulin plant (Costus pictus) is one of the folk medicines used for the treatment for Diabetes mellitus. This plant belongs to Costaceae family, which has been separated from Zingiberaceae on the basis of the presence of spirally arranged leaves and rhizomes being free from aromatic essential oils. The plant commonly known as spiral ginger is originated in Mexico and is found to have antidiabet...

Aluminum (Al) toxicity is a key factor limiting plant growth and crop production on acid soils. Increasing the plant Al-detoxification capacity and/or breeding Al-resistant cultivars are a cost-effective strategy to support crop growth on acidic soils. The plasma membrane H+-ATPase plays a central role in all plant physiological processes. Changes in the activity of the plasma membrane H+-ATPas...

Small molecules of plant origin can have different effects on bacterial cells. At present, it is great interest to determine the toxic such compounds in order assess potential their use veterinary medicine and medicine. The aim this work was evaluate toxicity various chemically synthesized small using a luminescent biosensor based Escherichia coli cell culture freshwater ciliate Stylonychia myt...

The toxicity of levofloxacin to yellow lupin plants was evaluated in this study. Recommended indexes of plant (roots and shoots) growth were determined and new indexes were proposed which better characterise the phytotoxicity of levofloxacin. These were, in particular, the activity of antioxidative enzymes, the content of free radicals, as well as the root protein content and the root protein p...
