Copper is a reddish-brown, ductile and malleable metal. It belongs to group IB of the Periodic Table. In compounds found in the environment it usually has a valence of 2 but can exist in the metallic, +1 and +3 valence ...

?letaliic vanadium does not occur in nature. Over 70 vanadium minerals are known, carnatite and vanadinite being the most important from the point of view of mining. Production of vanadium is linked with that of other ...

Ammonia (NH3) is a colourless acrid-smelling gas at ambient temperature and pressure. It can be stored and transported as a liquid at a pressure of 10 atm at 25 C. Ammonia dissolves readily in water where it forms, and is ...

Tributyltin (TBT) compounds are organic derivatives of tetravalent tin. They are characterized by the presence of covalent bonds between carbon atoms and a tin atom and have the general formula (n-C4H9)3Sn-X (where X ...

Aluminium is a silvery-white, ductile and malleable metal. It belongs to group IIIA of the Periodic Table, and in compounds it is usually found as AlIII. It forms about 8% of the earth's crust and is one of the most reactive ...

The dithiocarbamates included in this review are those that are mainly used in agriculture and form part of the large group of synthetic organic pesticides that have been developed and produced on a large scale in the last ...

Cypermethrin was initially synthesized in 1974 and first marketed in 1977 as a highly active synthetic pyrethroid insecticide, effective against a wide range of pests in agriculture, public health, and animal husbandry. ...

Pure pentachlorophenol (PCP) consists of light tan to white, needlelike crystals and is relatively volatile. It is soluble in most organic solvents, but practically insoluble in water at the slightly acidic pH generated ...

Phosphine, or hydrogen phosphide, is a colourless gas which is odourless when pure, but the technical product usually has a foul odour, described as "fishy or "garlicky", because of the presence of substituted phosphines ...

Mirex (C10C112) is a white crystalline odourless solid it is an extremely stable substance. Gas chromatography with electron capture detection is the analytical method most commonly used for its determination. Mirex is ...
