The Research and Special Programs Administration (RSPA) of the US Department of Transportation (DOT) published a list of the top 50 hazardous materials in a 1998-1999 summary of HAZMAT transportation incidents (24). The corrosive materials that were most involved in HAZMAT incidents in 1998 were sodium hydroxide solutions, basic inorganic liquids, hydrochloric acid, solutions, sulfuric acid, cleaning liquids, hypochlorite solutions, basic organic liquids, liquid amines, and ammonia solutions.

Metallic lead is soft, bluish white, highly malleable, and ductile. It is a poor conductor of heat and electricity and resistant to corrosion. A protective film of basic carbonate is formed on the surface of lead exposed to moist air. Lead reacts with water in the presence of air to form lead hydroxide. Inorganic Pb(II) compounds are mainly insoluble or slightly soluble in water. Exceptions are lead chlorate, perchlorate, nitrate, and acetate. Lead chloride is moderately soluble (9.9 g/liter at 20°C). The most important organolead compounds are tetramethyllead and tetraethyllead used as antiknock additives in fuel. Both are colorless liquids at room temperature with boiling points 110 and 200°C, respectively. Photolytically these degrade to RaPb , R2Pb , and Pb. The different chemical forms of lead have different toxicity, so that speciation information is important [1,2].
