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, ...

Propachlor is a pre-emergence and early post-emergence herbicide derived from acetanilide, and has been in use since 1965. The major formulations are as wettable powder, liquid flowable (suspension concentrate) and as ...

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 ...

This document represents the views of ICPFMC and is published by IPCS in an attempt to stimulate scientific discussion, as well as to provide guidance on the use of genotoxicity tests in chemical safety programmes. Although ...

This document is a review of occupational and environmental exposure to selected synthetic organic fibres. The particular fibres covered in this document have been selected because they are the only ones for which some ...
