| iodine (A nonmetallic halogen element; the poisonous, corrosive dark plates or granules are readily sublimed; insoluble in water, soluble in common solvents; used as germicide and antiseptic, in dyes, tinctures, and pharmaceuticals, in engraving lithography, and as a catalyst and analytical reagent) |

|
| ion exchange (The process in which ions are exchanged between a solution and an insoluble solid, usually a resin) |
schimb de ioni |
|
| ion exchanger (A permanent insoluble material (usually a synthetic resin) which contains ions that will exchange reversibly with other ions in a surrounding solution. Both cation and anion exchangers are used in water conditioning. The volume of an ion exchanger is measured in cubic liters of exchanger after the exchanger bed has been backwashed and drained, and has settled into place) |

|
| ionising radiation (Radiation that is capable of energizing atoms sufficiently to remove electrons from them. In this state atoms become more reactive, so that ionizing radiation increases chemical activity and in this way produces biological effects, including effects that involve alterations induced in DNA. X-rays and gamma-rays are the only electromagnetic waves that cause ionization in biological material) |
radiaţie ionizantă |
|
| ionosphere (A region of the earth's atmosphere, extending from about 60 to 1000 kilometers above the earth's surface, in which there is a high concentration of free electrons formed as a result of ionizing radiation entering the atmosphere from space) |

|
| iron (A malleable ductile silvery-white ferromagnetic metallic element occurring principally in haematite and magnetite. It is widely used for structural and engineering purposes) |

|
| iron and steel industry (Sector of the metallurgical industry dealing with the production of cast iron, steel and iron alloys. Emissions from these industries tend to settle quickly from the atmosphere and can lead to rising concentrations in the soil. The main raw material input to the production process is iron ore. Also recycled scrap is used) |

|
| iron industry (A sector of the economy in which an aggregate of commercial enterprises is engaged in the extraction and refinement of iron ore to produce cast iron, wrought iron and steel) |

|
| irrigation canal (A permanent irrigation conduit constructed to convey water from the source of supply to one or more farms) |
