Harm and protection of vanadium

wallpapers News 2021-11-10
Environmental hazards
Vanadium concentration in natural water is very low, 0.01 ~ 20ppb in general river water, the average is 1ppb. Seawater contains 0.9 to 2.5 PPB of vanadium. Although soluble vanadium content in water is very low, suspended vanadium content in water is very high.
The deposition of suspended matter causes vanadium to migrate to the bottom and purify the water. Vanadium mainly exists as VO3- anion in soil. The more oxidizing and alkaline the soil is, the more easily vanadium forms VO3- ion. When the acidity of soil increases, VO3- ion is easily converted to polyvanadate complex anion. They are easy to be fixed by clay and soil colloids and humus and lose activity, vanadium migration in the soil is weak.
Harmful effects of vanadium on the human body
The metal vanadium has very low toxicity. Vanadium compounds (vanadium salts) are toxic to humans and animals, and their toxicity increases with the increase of valence and solubility of the compounds. For example, vanadium pentoxide is highly toxic and can cause changes in the respiratory system, nervous system, gastrointestinal system, and skin.
Hazard prevention and control
Skin contact: take off contaminated clothes and rinse thoroughly with soapy water and clean water.
Eye contact: immediately open upper and lower eyelids and rinse with running water for 15 minutes.
Inhalation: Remove from the scene to the fresh air, wash the dust in the nasopharynx with water.
Ingestion: Seek medical advice if ingested by mistake. Symptomatic treatment.
Storage transport
Vanadium needs to be stored in a cool, ventilated warehouse. And vanadium must be kept away from ignition and heat sources. It should be stored separately from oxidants, acids, and edible chemicals, and must not be mixed. The storage place shall be equipped with the appropriate variety and quantity of fire-fighting equipment. The storage area shall be equipped with suitable materials to accommodate leaks.
