| metal fume fever | An occupational disease, characterised by malaria-like symptoms, due to inhalation of particles and fumes of metallic oxides. Fumes are formed by evaporation at very high temperature and condensation in air into fine particles. Synonym: brass founder's ague, foundryman's fever, metal fume fever, zinc fume fever.

| liquid metal | <radiobiology> Metal which has been heated past its melting point and can be used as a working fluid for pumping heat out from a powerplant. Liquid metal used as coolant in a system where significant magnetic fields exist, it behaves differently due to magnetohydrodynamic effects, these cause pressure which resists fluid circulation, suppression of turbulence, and altered flow patterns compared to non-magnetic liquid metal systems.

| liquid-metal fast-breeder reactor | <physics> Fission breeder reactor concept using liquid-metal coolant and breeding additional fuel off fast neutrons. See: breeder reactor. (09 Oct 1997) |
| heavy metals |
Mercury, lead, cadmium, and other heavy metals cannot be metabolized by the body and if accumulated, can cause toxic effects by interfering with various physiological functions. These substances are called "heavy metals," a term applied to metallic elements whose specific gravity is about 5.0 or greater, especially those that are poisonous.

| heavy metals |
Heavy metals are naturally occurring elements found in rocks and soils. They are also released to the environment by human activities. They generally do not change into other forms and therefore persist in the environment. Examples of heavy metals are mercury, cadmium and lead.

| heavy metals |
Metallic chemicals like cadmium, arsenic, copper and zinc that can be harmful pollutants when they enter soil and water. These chemicals are put into animal feed to help make animals grow faster. Heavy metals are present in human and animal waste and can enter the environment if waste is released without being treated. Animal waste is never treated to remove heavy metals. Once in the environment, heavy metals are almost impossible to get rid of because they do not decompose.
