Effects of hafnium on health and environment

Protective measures The metal hafnium does not normally affect human health, but some compounds of hafnium are toxic and can have adverse effects on human health, such as hafnium chloride which corrodes the skin and mucous membranes. So we in contact with hafnium compound, should first understand whether the compound is toxic, in contact with whether the need should be protective measures, such as wearing masks, gloves and so on. People who are regularly exposed to hafnium compounds should have regular medical examinations, especially for the liver, as animal studies have reported that hafnium compounds cause liver damage in animals. In addition, hafnium compound production sites should have good ventilation facilities, regular dust removal, reduce the concentration of hafnium compound dust in the air, avoid because of contact or inhalation of skin, eyes and mucous membrane caused by irritation.

Although the dense metal hafnium nature is not active, the surface of the formation of oxide covering layer, at room temperature is very stable, but the hafnium powder in the air is very easy to spontaneous combustion, so whether in the hafnium powder production workshop, or we use hafnium powder, should be properly kept hafnium powder, ensure good ventilation, avoid spontaneous combustion.

Plants absorb a small amount of hafnium from the soil, but it has no effect on plant growth. Animal studies have shown that hafnium compounds can irritate the eyes, skin and mucous membranes. So far, there have been no other negative reports on the effects of hafnium on the environment.
