Detailed introduction

Sodium arsenite

Sodium arsenite is an inoganic sodium salt with formula with formula NaAsO2. It has a role as an insecticide, an antibacterial agent, a herbicide, a rodenticide, a carcinogenic agent, an antineoplastic agent and an antifungal agent. It is an arsenic molecular entity and an inorganic sodium salt. Get price

Fluoride is known to diffuse through cell membrane causing accumulation in soft tissues resulting in impairment in the cellular activities. Present investigation demonstrates significant alteration in the level of few essential trace elements (Iron, Zinc Copper) in Guppy ( Poecilia reticulata Peters) chronically treated with 5.75 ppm, 7.18 ppm 9.58 ppm of Sodium fluoride for the period of Get price

Eichhornia crassipes

However, due to easy accumulation of toxins, the plant is prone to get contaminated when used as feed. The plant is extremely tolerant of, and has a high capacity for, the uptake of heavy metals, including cadmium, chromium, cobalt, nickel, lead and mercury, which could make it suitable for the biocleaning of industrial wastewater.

Hydrogen sulphide, a novel gasotransmitter involved in

Hydrogen sulphide (H 2 S) induces stomatal closure in a dose‐dependent manner. Stomatal aperture measurements were performed on Vicia faba epidermal strips preincubated for 2 h in opening buffer (10 mM K‐MES, pH 6.1; 10 mM KCl) under light, and treated with different concentrations of the H 2 S donors NaHS (grey bars) and GYY 4137 (white bars), or with 500 μM Na 2 SO 4 (black bar) for 90 Get price

Macrophytes are a well suitable for water cleaning because of their ability to grow in flooded conditions and therefore they are generally used in constructed wetlands of water treatment facilities. Among them, Phragmites australis has been successfully utilized for phytoextraction of several xenobiotics including pharmaceuticals ( Matamoros et al., 2005 ; Hijosa-Valsero et al., 2010 Get price

Nonetheless, it is common knowledge that problems with exotic macrophytes are pervasive, especially in southern states, and that many thousands of acres are affected. The Great Lakes all suffer from a variety of exotic species problems, and with the recent zebra mussel invasion, problems caused by exotic species appear to be getting worse. Get price

In addition, it was made a distinction between accumulation in a small concentrations range, which occurs due to physiological needs (e.g., Zn) and apparently uncontrolled accumulation (e.g., Cd) []. It was observed that the mollusks from the Black Sea have shown a great tendency to accumulate in high concentration Cd and Cu from sediments as well as Cd, Ni, and Cu from water. Get price

Historical ecosystem modelling of the upper Gulf of

Ecological conditions in the upper Gulf of California (Northwest Mexico) have deteriorated significantly over the past seventy years through the removal of nutrients and freshwater from the Colorado River. Acting at the same time, uncontrolled exploitation has brought at least three fisheries to collapse and several endemic species, such as giant Gulf croaker (Totoaba macdonaldi) and the Get price

Gold nanoparticle biodissolution by a freshwater

The Au biodissolution rate was highest for the biofilm with the lowest prevalence of metal-resistant taxa but the highest ability to release cyanide, known to promote Au0 oxidation and complexation. Macrophytes and the associated microbiome thus form a biologically active system that can be a major sink for nanoparticle accumulation and transformations. Get price
