This is a companion volume to Environmental Health Criteria 82: Cypermethrin. The Environmental Health Criteria (EHC) documents produced by the International Programme on Chemical Safety include an assessment of the effects ...

Lindane is a white, crystalline solid, with a weak, or no, odour (the characteristic smell of technical HCH is attributed to the impurities, particularly heptachlorocyclohexane). Lindane is stable to light, air, heat, ...

1,2-Dichioroethane is a colourless liquid, with a sweet taste aid a chloroform-like odour. Reportd odour thresholds are 25-450 mg/ni for perception and 162-750 mg/rn for recognition. 1,2-Dichiorethane is a volatile and ...

a- and 13-HCH can be determined separately from the other isomers, by gas chromatography with electron-capture detection, and other methods, after extraction by liquid/liquid partition and purification by column chromatography. ...

MIBK is a clear liquid with a sweet odour; the odour threshold is 1.64 mg/m3 (0.4 ppm). It is moderately soluble in water. MIBK can react violently with oxidizing and reducing agents. When heated, peroxides may form by ...

Formaldehyde is a flammable, colourless, reactive, and readily polymerized gas at normal temperature and pressure. The heat of combustion for formaldehyde gas is 4.47 kcal/g. It forms explosive mixtures with air and oxygen ...

Isophorone is a colourless liquid. Its odour has been described as similar to those of peppermint and camphor. It is soluble in water and is miscible in all proportions with aliphatic and aromatic hydrocarbons, alcohols, ...

Brodifacoum is an off-white powder, which is stable in the solid form. Its solubility in water is very low (less than 10 mg/litre at 20 °C and pH 7); it is slightly soluble in benzene and soluble in acetone.

Amitrole is readily soluble in water, methanol, ethanol, and chloroform, sparingly soluble in ethyl acetate, and insoluble in hydrocarbons, acetone, and ether. It forms salts with most acids and bases, and is a powerful ...

Methomyl is a white crystalline solid with a melting point of 77 °C and a vapour pressure of 0.72 mPa (25°C ). Its solubility in water is 54.7 g/litre and its octanol/water partition coefficient (K) is 1.24. It is stable ...
