All exposure determinations and risk assessments ultimately depend on accurate chemical analyses, and therefore some critical aspects of analysis for 2,4-D residues have been included in the present document. The available ...

Technical quintozene (pentachloronitrobenzene) is a white solid with a musty odour, that, is used in formulation as a soil fungicide and as a seed dressing. Hexachlorobenzene is a possible major contaminant in technical ...

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. ...

Although only key references essential for the evaluation of the risks for human health and the environment are cited, this document is based on a comprehensive search of the available, original scientific literature, while ...

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 ...

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 ...

Acrylonitrile is a colourless, volatile, chemically reactive liquid; it does not occur as a natural product. The monomer is used world-wide, on a large scale, in the manufacture of polymers, fibres, and rubbers and as a ...

The terms 'fluorine" and 'fluoride' are used interchangeably in the literature as generic terms. In this document, the terminology suggested by US NAS (1971) is followed: "This document, rather than following common usage, ...

Dichlorvos, an organophosphate, is a direct-acting cholinesterase (ChE)l inhibitor. Since 1961, it has been commercially manufactured and used throughout the world as a contact and stomach insecticide. It is used to protect ...

The major sources of exposure to chlorine and hydrogen chloride that are of significance for human health are found in industry. Both chlorine and hydrogen chloride are corrosive to most construction materials, as well as ...
