Ammonia is a colourless acrid-smelling gas at room temperature and normal atmospheric pressure. Most people can identify its odour at 35 mg/rn3 in air. It can be stored and transported as a liquid at a pressure of 10 ...

Environmental protection often Involves Costs to the enterprise. In the first four units, we have analysed the reasons why these costs must be accepted, how to minimize them, how to anticipate and plan for effective ...

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, ...

Chlorothalonil is a colourless, odourless, crystalline solid with a melting point of 250°C and a vapour pressure of 7.63 × 10-5 Pa (5.72 × 10-7 mmHg) at 25°C. It has low water solubility (0.6-1.2 mg/litre at 25°C) and an ...

The document focuses on describing and evaluating the risks of methylene chloride for human health and the environment. Methylene chloride (dichloromethane) is widely used as a multi-purpose solvent and paint remover. ...

Nephrotoxicity can be defined as renal disease or dysfunction that arises as a direct or indirect result of exposure to medicines, and industrial or environmental chemicals. It is well established that toxic nephropathies ...

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 ...

Hexachlorobutadiene is a non-flammable, incombustible, clear, oily and colourless liquid at ordinary temperature and pressure. It is poorly soluble in water but miscible with ether and ethanol. Hexachlorobutadiene is not ...
