The first part of this project, dealing with in vitro studies, was published in 1985 (Ashby et al., 1985) and was summarized in Environmental Health Criteria 47 (WHO, 1985). The second part, which is the subject of this ...

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 ...

1-Propanol is a colourless, highly flammable liquid that is volatile at room temperature and normal atmospheric pressure. It is miscible with water and organic solvents. Analytical methods for propanol include gas ...

Cyhalothrin is formed by esterifying 3-(2-chloro-3,3,3-trifluoroprop-1-enyl)-2,2- dimethylcyclopropanecarboxylic acid with alpha-cyano-3-phenoxybenzyl alcohol, and it consists of a mixture of four stereoisomers. ...

1,1,1-Trichloroethane is a chlorinated hydrocarbon which is manufactured from vinyl chloride or vinylidene chloride by chlorination. The world production was approximately 680 000 tonnes in 1988. It is a colourless, ...

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 chemical name for diazinon is O, O-diethyl O-2-isopropyl-6-methylpyrimidinyl-4-yl phosphorothioate. The pure material forms a colourless liquid with a faint ester-like odour. The technical active ingredient is a ...

Methanol is a clear, colourless, volatile flammable liquid with a mild alcoholic odour when pure. It is miscible with water and many organic solvents and forms many binary azeotropic mixtures. Methanol occurs naturally ...

The PCBs are chlorinated hydrocarbons that are manufactured commercially by the progressive chlorination of biphenyl in the presence of a suitable catalyst (e.g., iron chloride). Depending on the reaction conditions, the ...
