Permethrin was first synthesized in 1973 and marketed in 1977 as a photostable pyrethroid. Approximately 600 tonnes per year of permethrin is at present used world-wide, mostly for agricultural purposes. It has a potential ...

Man-made mineral fibres (MMMF), most of which are referred to as man-made vitreous fibres (MMVF), are amorphous silicates manufactured from glass, rock, or other minerals, which can be classified Into four broad groups: ...

Methyl bromide is a colourless gas at room temperature and standard pressure with a boiling point of about 4 °C. It is heavier than air and easily liquefied below its critical points. It is odourless, except at high ...

Alpha-hexachlorocyclohexane (alpha-HCH) is a major by-product (65-70%) in the manufacture of lindane (> 99% gamma-HCH). Its solubility in water is low, but it is very soluble in organic solvents such as acetone, chloroform, ...

This Environmental Health Criteria monograph on brominated diphenyl ethers has been prepared as part of an overview on the impact of a number of flame retardants on human health and the environment. The group of polybrominated ...

Glyphosate is a weak organic acid consisting of a glycine and a phosphonomethyl moiety. The empirical formula is C3H8NO5P. Glyphosate is usually formulated as a salt of the deprotonated acid of glyphosate and a cation, ...

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 ...

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 ...

Toluene diisocyanates (TDIs) are synthetic organic chemicals of low relative molecular mass (174.17). They are colourless to pale yellow liquids, at room temperature, with a distinct pungent odour detectable around 0.7 ...

This document comprises a review of data of effects of magnetic field exposure on biological systems, pertinent to the evaluation of health risks for man. The purpose of the document is to provide an overview of the known ...
